The centrifugal nozzle is a common spray device. According to records, it was first invented by Joseph Sloan in the mid-19th century.
Sloan was a British engineer whose centrifugal nozzles were designed for use in agricultural sprinkler systems. They were designed to disperse water into a mist through a rotating device, allowing for more efficient irrigation.
However, it is not popular in drone applications because it does not have enough pressure and cannot control the size of spray particles well. Sometimes large droplets can burn fruits and crops.
DJI has independently developed dual centrifugal atomization nozzles since the model T40, that effectively solve the problems of uneven atomization and dripping.
We summarized the following points to share them with you:
Uniformity: DJI’s dual centrifugal nozzles can evenly divide liquids more effectively, producing a finer, more uniform atomization effect, thereby improving coverage, effect uniformity, and greatly increasing product utilization.
Spray particle size: Through parameter settings on the Intelligent remote control, farmers can easily control the size of liquid particles and select the mist size required for different crops, to better control diseases and pests in time. This controllable size of droplets can help farmers more evenly cover the crop surface that needs protection, thereby greatly improving the utilization rate and effectiveness of liquid spraying.
Adjustable spraying width: By using the remote control, farmers can adjust the spraying width according to different needs and application scenarios. This greatly facilitates the needs of different terrains and crop operations.
Generally speaking, DJI’s drones are so popular among growers, mainly because of their advanced design and manufacturing, which can help users fly safely in complex farm environments and bring advanced technological work to growers.
Some friends think, “As long as I can fly small drones, there will be no problem for me to fly agricultural drones.”
That can’t be further from the truth. The working principle of large agricultural drones is much more complicated than that of small drones, and you need to use large agricultural drones to work in the fields for a long time, unlike flying small drones which you only use few times in a year.
You need to know how to avoid some potential risks. You need to know how to quickly diagnose and repair instead of sending it back to the maintenance center. This can ensure that you can operate the agriculture drone in the field without interruption.

We know everyone’s love for large equipment, so it’s not allowed to be mad when you see this comparison.
No matter which tool we use, there is only one purpose, which is to achieve better production results.
There’re lots of differences between ground rigs and DJI drones.
* DJI’s nozzles use their self-developed dual-atomization centrifugal nozzles, which effectively solves the problem of uneven spray particles on a single-layer spinner on the market. Therefore, its atomization effect is better and nothing is wasted.
* The spraying pressure is different from our mechanical pressure gauge. Its particle size and the amount of each Acre are controlled by the computer system, which is followed by the complex computing power.
* Whether dripping or not is not controlled by the rubber ring. The T50 has solenoid valves developed by DJI that can control spraying within milliseconds.
* And much more…

When the crops are short and the land is in good condition, large equipment has many advantages.
Mainly in the middle stages of the crop, the roots of the crops are absorbing nutrients and we do not want compaction. Also, large equipment is inconvenient to operate after rain, drones can come in handy.
The last focus is on the later stage. Variable spraying in crops that are about to mature to protect yields, spraying foliar fertilizers to increase crop absorption capacity and increase yields, and spreading cover crops can be done several months in advance to increase soil fertility.
Many drones of different brands have gradually entered the Canadian market. There were still many people watching the excitement, but by the end of the 2023 season, everyone is certain about the quality, ease of use and safety of drones. DJI Agras The T40 has become the top model of agricultural drones. Even before the T50 is launched, the T40 has already been sold out.
When you are on the top of a mountain, you can see the rushing river. When you are on top of the peaks, you can feel the strong wind. When you have a deep understanding and learn what is a safe and qualified agricultural drone, you will no longer use the capacity and speed as the criterion.
A company does not achieve success in a day. High-quality products are the first priority, safety is crucial, and ease of use and smooth after-sales service are indispensable.
DJI wants to use the best materials to make the best drones, but wants their agricultural drones to be affordable for every ordinary farmer.
DJI said that they will be like farmers farming, no matter how hard they work, no matter how much they gain, they will not do anything deceptive, but will only be a company that everyone trusts, and a company will always consider you as DJI’s family.
DJI did it!
And more!

In 1987, Yamaha produced the first 20kg spraying drone “R-50”. After that, Japan widely used unmanned helicopters for field crops. But they don’t want to sell the device to other countries.
At that time, there were self-assembled agricultural drones on the market, but they were not only expensive, but also prone to problems. To be more direct, their operability was not quite as good. This “no drone available” situation lasted until November 2015 – DJI entered the market. DJI has brought technology, experience and a mature service system, which to some extent has gradually pushed the industry towards formalization.
Since 2015, DJI’s agricultural drone hardware and applications have developed rapidly, and market ownership and operating area have grown rapidly. From the MG series to the T16, T20, T10, T30, and T40 series, DJI Agriculture has completed the entire line of product upgrades, integrated intelligent configuration, cloud platform, and equipment service system integration.
What is even more popular among the agricultural community is the “smart agriculture” solution that DJI has built since 2019. It can be understood as the agricultural version of the “metaverse”, which is built through the combined use of AI, Internet, intelligent system and other black technologies. Since then, a new agricultural system linked by digital technology.
In this system, from digitalization and intelligence of the entire process to reducing management costs and improving agricultural efficiency.
At present, this platform has formed a “small closed loop” of “data collection – analysis and decision-making – efficient execution”, and this “small closed loop” can be embedded into the “large closed loop” of smart agriculture to provide farmers with systematic Smart agriculture solutions.
Early drones were expensive, and DJI stated that drones are not the exclusive preserve of a few large farms. They are committed to making high-quality spraying drones affordable to ordinary farmers. Great efforts have been made in terms of product technology and ease of use. The hard work of thousands of developers and engernieers is behind this easy-to-use and safe device.
Compared with ground machinery, agricultural drones have the advantages of high efficiency and strong terrain adaptability. The application of drones has effectively filled the shortcomings and gaps in the application of traditional ground agricultural machinery, and is of great significance to improving the mechanization of weak points in agriculture. In addition, compared with ground machinery, drones have better intelligent software and hardware systems, which are also an important support for the continued promotion of digital agriculture in the future.
The prosperity of the industry also depends on the establishment of an ecosystem, and professional drone pilot training and pre-sales and after-sales service systems are critical. In order to ensure that customers can understand the operating principles of drones and know how to self-predict some risks and failures, DJI established the DJI Academy as an important guarantee for the safety of farmers flying drones.
For example, in terms of agent training, DJI Academy has carried out pre-sales training, after-sales training, instructor training, special training and other trainings to help them quickly understand the characteristics of new products, improve actual maintenance and three-guarantee service capabilities, and promote the conversion of potential users, achieved results such as sharing successful cases with other dealers.
Regarding future market trends, judging from the needs of our customers in the Canadian market in the past few years, as agricultural pests and diseases intensify and farmers’ costs continue to increase, agriculture drone products are becoming more and more widespread, and agricultural producers and operators are paying more attention to crop protection.
Currently, drones are mainly used in the United States to spray fungicides after rain to promptly control the spread of soybean white mold, and to spread cover crops before harvesting tall crops to increase soil fertility.
Grower’s Questions:
We like to use as much water as we can and 10 to 15gal an acre at times (depending on Chem) isn’t out of the question, and can do 160ac in ~1.5 to 2 hours a field depending on fill time.
Answer:
The T40 operates at a rate of 40 acres/hour. If you need to achieve the same coverage area, you need 2 drones to work together, and DJI drones use high concentration and low flow technology to make the droplets more uniform and effectively improve the pesticide utilization rate. The pesticide application amount is 2-3 GPA Depends on product and weather.
Current operation: 1 operator, 1 sprayer, 1-2 fills, 7-15gal/ac.
Answer:
You are right, drone spraying does not have the advantages of large tractors in the early stage if the ground condition is good for the tractor to get in.
Drones have been used in the following scenarios in these years: *Soft ground *After the rain *Tall crops *Spot spray weeds *Only spray the edges of the field *Cover crops in mature crops
Protect crops while increasing yields and profits.
Grower’s Review on the use of drones:
No tracks, can go way before a ground rig in wet conditions, perfect for spot spraying weed patches like toadflax or Canada thistle.
I like the drone can blow droplets to the intersections and backs of leaves.
Cell phone controlled drones are usually controlled via an APP on a smartphone or tablet connected to a Wi-Fi or Bluetooth device.
Drones of this type usually have shorter control distances and lower signal stability because they are limited by the wireless signal range and performance of smart devices.
Agriculture Drones operated by professional DJI remote controllers usually use dedicated remote controllers. These remote controls usually use dedicated wireless communication protocols (such as OcuSync or Lightbridge), which have longer control distance (up to 2KM) and more stable signal transmission. These professional remote controls also typically have more physical control buttons and joysticks, providing more flight control options and features.
Therefore, drones operated by professional DJI remote controllers are usually superior to drones controlled by mobile phones in terms of signal stability, control distance and flight control options.
The battery of a drone is an important part of the drone. You may have noticed that there are currently high-performance lithium batteries and air-cooling technology represented by DJI on the market.
At the same time, you may also see that some drones use mist-cooled batteries.
What’s the difference between them?
We mainly look at their safety and reliability.
DJI’s lithium batteries are made of high-quality materials, charge and discharge very smoothly, and can operate safely and efficiently for a long time. You can all know this through the users of DJI Agras drones around you in the past few year.
Other brands of drones use the more traditional mist-cooled battery technology on the market. This kind of battery is relatively low-cost and has poor heat dissipation effect. The manufacturer basically recommends cooling it in water.
However, after long-term use, the battery sealing effect will be reduced, it will cause inevitable accidents.
Therefore, DJI’s drone battery is one of its highlights. There are many more, you are welcome to visit our show room or register for our Zoom to learn more.
1- Spring: T40 drones can help spread alfalfa or clover in winter wheat at 10lbs/acre, increasing soil N fertility, plus, the crops also gain other intangible benefits, such as improved soil structure, and increased beneficial soil microbial populations. (Thanks to DJI firmware upgrade, the current working efficiency of T40 is about 300-400acres/day)
2- Summer: Drones can help keep the foliage coated at all times. According to our growers who use drones “Drones can be great! It blows the mist droplets to the intersection and back of the leaves.”
Multispectral UAV M3M A- Spring: 1- It can help you check the land leveling situation in time and generate a terrain leveling map with a positioning accuracy of 2.74 cm. This can help you make land leveling plans before planting. 2- Field patrol, this fast and convenient tool can help you obtain the precise data you need within half an hour, reducing errors in judgment. 3- Weeds, we usually spray the whole field, with this drone you can spot spray the weed areas by using both tractors and drones.
B- Summer: Different from satellite multispectral, the chlorophyll index collected by M3M drone’s multispectral is real-time, so you can make correct judgments on crop management during the same day. Then use tractors or drones to carry out spot spraying management.
Recreational drones are not the same as M3M. They do not have sun-sensor, so when you use these recreational drones to take photos, the photos may be taken when there is reflection, which will cause your data to be inaccurate, thus this creates unnecessary risks for crop management.
3- Autumn: Check weed areas for timely crop quality control.
Software Platform: These DJI devices do not require third-party software and form a convenient closed-loop operation for agricultural management, thereby greatly reducing the burden of data processing on growers.
The melting snow in the land is the prelude to the arrival of spring and the starting point of the cycle of four seasons. So, how can multispectral drones help manage weeds at this stage?
In Spring, the Mavic 3 multispectral (M3M) drone can be used in a variety of ways for weed detection.
Early detection: Multispectral imaging can detect the early stages of weed growth. By identifying weeds early, farmers can take timely action to prevent them from competing with crops for nutrients, water and sunlight in the future.
Mapping weed areas: Mavic 3 can be used to create multispectral data of weed infestation within agricultural fields and quantify weed coverage. This information can help farmers prioritize areas for targeted weed management interventions rather than blanket spraying.
Precision herbicide application: Mavic 3 software uses multispectral data to identify and map weeds, allowing farmers to use precision herbicide application technology.
Not only can the variable job maps generated by M3M be used directly on DJI Agras drones, you can also upload the images for use by using a GPS-guided tractor sprayer. This helps farmers minimize chemical use and reduce environmental impact.
Monitor weed control efforts: Once weed control measures have been implemented, the Mavic 3 can be used to monitor the effectiveness of those interventions over time. By regularly collecting multispectral data, farmers can assess changes in weed coverage and adjust their management strategies as needed.
The Mavic 3 multispectral drone has become a valuable tool for spring agricultural weed detection and management, helping farmers increase efficiency, reduce costs and minimize environmental impact.
Here’s an article we would be glad to share with you:
Spot Spraying With Drones: Using Technology to Cut Herbicide Use in Half
We all know that summer is the time when agricultural drones are used most frequently, so what can agricultural drones do starting from March every year? We briefly list a few things that producers are using them nowdays:
A: Planting T40 Drone: Spreading red clover. You no longer need to worry if the land is too wet. M3M Drone: For monitoring sowing and planting processes. They can help check data on sowing and emergence rates, plant distribution and growth, and help farmers optimize planting plans.
B: Pest and disease monitoring M3M Drone is a mapping and multispectral drone that can be used to detect pests and diseases in farmland. This helps detect plant health problems early, allowing farmers to take preventive management.
C: Irrigation management By monitoring the whole fileds, M3M drones can accurately analyze the height of the terrain, helping farmers manage water resources more effectively.
There are more. If digital agricultural management can save us worry and effort, why not let them do it?
If you plan to use a drone in March, we recommend that you give yourself one to two months of training time to fully understand and learn the use of drone equipment. If you haven’t planned it yet, we recommend that you make an appointment with our agricultural drone service team to help you protect your crops and help make the soil healthier.
Your favourite potato chips are actually related to drones. Let’s take a look at what kind of technological care it needs to grow.
Speaking of crispy potato chips, everyone has eaten them, but you may not know what kind of technological care a potato needs to undergo during its growth process before it grows into a potato and then sliced into chips.
“For agronomists, taking care of potatoes is like taking care of children” – the drone specialists at DJI Agriculture.
They will need to pay attention to its growth and pests at any time, and apply fertilizers and pesticides according to the farming season. Once there is a problem, a year of hard work will be in vain.
Since 2020, DJI Agriculture has begun to provide a digital agriculture solution for a world-renowned food company. It provides a complete set of solutions for terrain monitoring – growth monitoring – pest monitoring – variable fertilization and pesticides through drones to provide refined and digitalized potato planting. management to increase production and income. So far, the Phantom 4 multispectral drone has been applied to its 14 farms, using an area of more than 10,000 Acres.
(Note: The latest multispectral drone model released by DJI at the end of 2022 is the Mavic 3 multispectral）
Terrain monitoring
Land leveling is very important for potato growth. Uneven drip irrigation plots can easily cause uneven distribution of water and fertilizer, and the growth of plots varies greatly. At the same time, depressions are prone to the accumulation of water, resulting in a high incidence of pests and diseases.
In August 2022, at the Hebei farm of Lay’s Farm, agronomists used the Phantom 4 multi-spectral drone to monitor the elevation of the fields and then reconstructed the aerial imagery through the DJI smart agriculture platform to identify the highlands and depressions of the plot.
The blue part is low-lying fields
Based on the elevation map, agronomists can focus on and inspect depressions during periods of high disease and insect pest incidence to improve management efficiency. In addition, when laying the drip irrigation belt, it can also be designed according to the elevation map to make up for the spatial difference of water and fertilizer caused by the height of the terrain.
Growth monitoring
In the past, the farmland of 100 Acre required an agronomist to walk a day to complete it, and it could not completely cover every corner. Multi-spectral drones can complete field inspections in a few hours so that the whole field can be seen at a glance, and the growth of the whole field can be viewed through vegetation indices such as NDVI.
In 2022, Lay’s Farm used the Phantom 4 multi-spectral drone to monitor the farmland, capture the difference in the growth of potato plants, and make timely adjustments to farmland management.
Pest monitoring
In the past, agronomists needed to inspect the growth of potatoes on foot, but due to the limitation of walking speed and field of vision, it was easy to miss early disease sites. The use of drones can achieve efficient and full coverage of the field, greatly improving management efficiency and quality. Based on high-definition images captured by drones, combined with
AgroScout’s artificial intelligence automatic identification can also efficiently monitor potatoes for early blight, late blight, nutrient deficiencies, insect pests, and other abnormalities.
Variable Fertilization
Traditional crop protection operations are generally applied throughout the field and cannot be targeted with the areas. There is the problem of excessive use of pesticides and fertilizers, resulting in waste of input and environmental pollution.
In July 2022, Lay’s Farm used the Phantom 4 multispectral drone to monitor potatoes, accurately judged the difference in potato field growth based on NDVI vegetation index, and generated a variable fertilization prescription map to guide the T40 drone variable spraying of foliar fertilizer. The dosage of 24L/Acre is used for areas with weak growth, and the dosage of 12L/Acre is used for areas with better growth. While reducing the amount of fertilizer, uniformity of growth is ensured.
In addition, traditional ground rig spraying needs to reserve lanes for tractors, which will occupy about 1/7 of the farmland area. The use of drones for full flight control can avoid production losses caused by reserved aisles, which is equivalent to avoiding a 5% production reduction.
Tractor tracks
In addition, local agronomists said that in the case of a lot of rain, large tractors could not go to the field, which would have a greater impact on agronomic operations.
Moreover, in the later stage of potato planting, the tractor entering the field easily scratches the potato seedlings, increasing the risk of disease occurrence and spread. Drone operation does not touch soil and plants, reducing plant damage.
Lay’s, a global food and beverage industry leader, is committed to building a sustainable food system and promoting sustainable agriculture. By providing reliable digital agricultural solutions and intelligent equipment, DJI helps to achieve refined management of potato cultivation and promotes the green and high-quality development of the potato industry.
In the future, DJI Agriculture will continue to innovate, using advanced technology and solutions to empower more partners with field management, help improve the quality and efficiency of agricultural production, make agriculture easier, and make life better.

A peach orchard in Jingshen Village, Taigu District, Shanxi province suffered devastating aphid swarms this year due to insufficient pest control and unfavorable weather, which would have resulted in severe yield decreases if not controlled. The DJI Agriculture T20 aerial application drones were used to spray pesticides to control the pests in the orchard.
This operation was carried out in Jingshen Village, Taigu District, Shanxi province on June 3, 2020. The peach trees were 10-15 years old and 2 meters high with a crown diameter of 3 meters, and in the shape of open-top heart.
Overview of Pests
A large number of aphids were found on leaves, trunks and branches of the peach-bearing trees, particularly on the tender treetops, with up to 800-1,000 aphids on the back of a single leaf. As a result, the leaves curled, withered and turned black.
Aphids cause severe damage
Operation Parameters
Interpretation of Parameters
Speed (2m/s): Given the severe damage caused by the aphids, the operation speed was set to 2m/s to ensure a sufficient dosage was kept for the back of leaves.
Operation spacing (4m): The peach trees are in the shape of an open-top heart, with thin crowns, and a width of up to 4m.
Water consumption per hectare (75L): Water consumption was increased to 75L/hectare given the massive number of aphids on the backs of leaves.
Flight height (2m): Testing data indicated that 2m was high enough for the spray to penetrate the crown canopy, given the large weight of T20 and the strong wind.
T20 in operation
Pesticide Information
Note: The pesticide consumption was increased as a result of the severe damage caused by aphids resulting from poor management. Besides, proper adjustments are needed depending on the severity of the damage caused by the pests and the density of the crown canopies. Other pesticides may be used as alternatives in the future to avoid pesticide resistance with the aphids.
Pesticides
In this case, acetamiprid and avermectins-imidacloprid were used.
1. Acetamiprid
This product is a nitromethylene heterocyclic pesticide, which kills pests on contact and causes stomach poisoning. The pesticide is highly penetrative and can effectively control aphids and other pests. It targets the nicotinic acetylcholine receptor at the synapse of the insect’s nervous system to interfere with the conduction of stimulus and blocks the pathway of the nervous system, resulting in a buildup of acetylcholine at the synapse, and paralyzing and eventually killing the insects.
The product is toxic to bees and silkworms and should be handled with caution during florescence. Do not use it together with any alkali substances.
2. Avermectins-imidacloprid
This product is a compound of avermectins and imidacloprid.
(1) Avermectins
The product is a macrolide disaccharide pesticide, which kills pests on contact and causes stomach poisoning and has slight fumigation effect. It kills imagos but not eggs. It interferes with the insect’s nervous physiological activities.
The product is toxic to bees and silkworms and should be used with caution during florescence. Do not use it together with any alkali substances.
(2) Imidacloprid
The product is a nitromethylene pesticide, which kills pests on contact and causes stomach poisoning as well as systemic effects. It can control aphids effectively. Upon reception of this pesticide, the normal conduction of the central nervous system of the pest is blocked, resulting the paralysis and death.
The product is toxic to bees and silkworms and should be used with caution during florescence. Do not use it together with any alkali substances.
Control effect
Follow-up 72 hours after application: Evaluation conditions: under normal weather conditions, without rain, and within 72 hours after application. According to the on-site evaluation by the Plant Protective Station of the Agriculture Bureau of Taigu District, Jinzhong City, Shanxi Province, the control effects are as follows:
For treetops with severe insect damage, the death rate of aphids on the front of leaves was greater than 99%, while on the back of leaves greater than 95%, and on the trunk greater than 99%. The results met expectations.
Effect after application
Aphids on treetops with minor pest damage were essentially eliminated, and the health of leaves was obviously improved.
More than 95% of the aphids on the surface of bearing leaves were killed.
All aphids on the trunks were eliminated.
Summary of Experience
(1) The aerial application drones used for this operation are suitable for peach trees. The pesticide was properly selected, and the dosage met the requirements given the pest damage. The flight parameters and the flight plan were appropriate. In addition, the meteorological conditions were also satisfactory. Therefore, the pest control was very successful.
(2) Wind scale: During this operation, the wind scale was 0, which had no impact on spraying. In case of stronger wind, it is advised to lower the flight height as needed. When the wind exceeds gentle breeze, stop spraying.
(3) The temperature (30°C) and the relative humidity (80%) had little impact on the deposition and evaporation of the mist. In case of high temperature or low relative humidity, increase the water amount as needed, or stop spraying.
(4) Flight parameters: With a broad wind field, the T20 drone covered the whole crown canopy. It is suggested that various speeds and operation spacings should be tested in the future to ensure higher efficiency of T20 for operation on peach trees.
About Our Team
This pesticide application effect test is a field test for the project “Standard Operation Code for Plant Protection Machinery in Orchards”, which is jointly implemented by DJI Agriculture and the Center for Chemicals Application of China Agricultural University.
The test was supervised by Professor Wu Zhiming from Shanxi Agricultural University. A group of experts determined the flight parameters, plan, and pesticide technology. No repeated spray and missing spray were found during the field operation, and the pesticides were evenly applied, indicating that the Fruit Tree mode of T20 drones has satisfactory effect.
Using drones to pollinate pear trees can not only improve the growth of crops but also promote the germination of pollen and the growth of pollen tubes, thereby increasing the rate of speed setting and fruit set.
In the past, in addition to bee pollination, there was artificially assisted pollination, but it was time-consuming, labor-intensive, costly, and uneven. The flowering period of pear trees is short. Normally, 40% of the flowers are pollinated for the first time, and 70% of the flowers are pollinated for the second time. However, due to the low efficiency of artificial pollination, the whole process can only be completed once, which greatly affects the fruit setting rate.
Nowadays, the use of drones for liquid pollination has become the choice of more and more farmers due to its high efficiency, high fruit set, and high yield.
The DJI agricultural drone custom farming team in northern China has been the first to use DJI plant protection drones to carry out liquid pollination of pear trees since 2019.
Due to its high efficiency, uniformity, and pollen saving, the team quickly opened the drone service market for pear tree pollination.
Two people a day and one drone can operate 40Acres orchards, which greatly improves the operation efficiency. From April 4th to 13th this year, they invested a total of 15 T-series DJI agriculture drones to pollinate 1700Acres pear trees.
“We used T16 for pollination in 2019, and many orchard farmers asked us to use DJI drones for pollination this year.”
Precautions for configuring pollen solution
1- Purified water is required to ensure the quality of the water.
2- Add sugar to the water to provide nutrients to the pollen, ensure the activity of the pollen, increase the viscosity of the pollen, and improve the adhesion rate.
3- It needs to be prepared and used immediately to avoid pollen inactivation.

DJI agricultural drones can penetrate the pollen solution from the top of the pear tree to the roots with a strong wind field penetration, and the pollination is uniform and the effect is good.
Tip: When working on pear trees, you should avoid the high-temperature time, between 6-25 °C, to ensure the pollination effect.
Compared with manual work, drones pollinating fruit trees can not only help local growers reduce costs, ensure efficient pollination rates, improve the yield and quality of pears, but also drive local employment rates.

1. Pain Points in the Aerial Protection of Lychee Trees
Lychee, along with longan, bananas and pineapples, are known as the “Four Great Fruits of Southern China”. In 2020, lychee was grown on approximately 540,000 hectares of land in China, distributed mainly in provinces such as Guangdong, Fujian, Guangxi and Hainan. Guangdong alone has about 273,000 hectares of lychee orchards, which accounts for over 50% of the total cultivation area in the country.
In lychee orchards, crop protection operations are typically carried out 14-16 times on average a year (the number of spraying rounds vary depending on the region, crop variety, and management method, from 6-8 times to 20 times a year). In cases where crops need to be sprayed frequently, the combined factors of limited time windows and labor shortage drive up the operational cost.
Agricultural drones, the Phantom 4 RTK, the Phantom 4 Multispectral and other advanced tools and technology are constantly being innovated and evolving to reshape people’s production methods and lifestyles. The replacement of labor with machines addresses the issues of labor shortage and high production costs faced by fruit farmers.
Firstly, lychee (or longan) trees typically live longer than citrus and mango trees (those in some lychee orchards in Maoming are 20 to 30 years old). The size of lychee trees and their canopy diameter (usually six to eight meters tall, and canopy diameter four to six meters) are both larger than those of citrus and mango trees. Lychee plants enjoy sunlight with most of their leaves growing in the outer layers while the foliage closer to the center is sparse. In comparison, the leaves of citrus and mango trees are denser in their canopy. This presents a great challenge to agricultural drones, whereby the pilot must ensure the droplets can penetrate the plants while not harming the flowers and fruits with the strong draft from the aircraft. As a result, we had to conduct a large number of spraying tests within the growth cycle of lychee plants, to confirm the operating parameters suited for lychee spraying.

Secondly, most of the lychees in Guangdong are planted on hill slopes. The varying heights of the trees, altitude difference of the ground, and intricate power lines in these locations are particularly challenging for terrain-follow flights and obstacle avoidance by drones.
For the T30 agricultural drone, you would first need to generate a 3D map of the orchard and plan a 3D flight path using the Phantom 4 RTK. For the T40 or T20P, if the terrain’s incline is less than 45 degrees, the area can be mapped and a 3D route generated with the agricultural drone directly, which reduces the difficulty and cost of the operation.

2. Aerial Protection Solution for Lychee Trees
To tackle challenges of aerial fruit tree spraying, DJI Agriculture has been innovating its technology constantly to offer optimal solutions. For large orchards with steep slopes and complex terrain, the Phantom 4 RTK is used to survey the area, with a 3D map and flight routes then generated with DJI Terra or DJI Agras Intelligent Cloud, and then imported into the agricultural drone for it to carry out the spraying operation. For smaller orchards with flat terrain, the T40 or T20P can be used to map the area and plan a 3D flight operation directly.
DJI Agras Intelligent Cloud
The Fruit Tree Mode has two spraying and four planning modes. The two spraying modes are Continuous Spraying and Spot Spraying. The four planning modes are Distance Interval (Auto), Tree Crown Center (Auto), Semi-automated, and Manual.
Multiple Spraying Methods
[Continuous spraying]: The drone sprays evenly on the fruit trees throughout the flight. This method has highly efficient and suited for orchards with evenly spaced trees.
[Spot spraying]: The drone only sprays while hovering or circling over the top of each tree. This method is less efficient and suited for orchards with scattered trees or where only tree crown centers need to be sprayed.
The Two Spraying Modes
Multiple Route-planning Methods:
[Distance Interval (Auto)]: Adds field and boundary points, and automatically generates a zig-zag route with the same line spacing, similar to flight paths for field operations.
[Tree Crown Center (Auto)]: Adds field and boundary points, and automatically generates a route including all the tree crown centers.
[Semi-automated]: Adds waypoints along the fruit trees, which automatically connect to form a route. The route is automatically adjusted to link to the surrounding tree crown centers, generating a final operation route.
[Manual]: Adds waypoints along the fruit trees, which automatically connect to form an operation route.
The Four Planning Modes (From left to right, Auto Distance Interval, Auto Tree Crown Center, Semi-automated, Manual)
For better results and efficiency, the “Continuous Spraying – Distance Interval (Auto)” and “Continuous Spraying – Semi-automated” modes are typically used, depending on the terrain of the orchard. Due to the tall heights and dense canopies of lychee trees, the height and row spacing applied in operations would be slightly smaller than those for citrus and mango trees.
3. Setting Operating Parameters
The operating parameters for fruit trees are determined based on many factors, such as their growth momentum (e.g. age, height, canopy diameter, etc.), growth phase (e.g. flowering, fruiting, shoot controlling or other phases), the growth phase of the targeted pests or pathogens (e.g. eggs, larvae, or adult worms), pesticide types, and weather. By taking into account these conditions together with the drone’s performance, you could then decide the best parameters to operate under. Lychees are susceptible to fewer pests and diseases. They include Litchi stem borers, eriophyid mites, and geometer moths, as well as fungi such as Litchi downy blight and Litchi anthracnose.
The following parameters are based on operations carried out on lychee orchards in Maoming. They may vary from location to location and are thus for reference only.

Note that the more optimal parameters had been tested and verified continuously during the growth cycle of lychee trees. As it stands, the parameter categories for which we have operated the most are lychee trees around four to six meters tall and canopy diameter around four to five meters long. For specific pesticides, the above parameters deliver comparable results to those of manual spraying. The other parameters had been tested with smaller sample sizes and therefore should be set with more care and discretion before they are applied.
Switzerland contains a total vines area of 14712 ha. The annual turnover of the grape growers in Switzerland is approximately CHF 550 million.
For the optimisation of the grape harvest, viners treat the plants with pesticides, multiple times per season. Traditionally, this work is mostly performed manually or with specialized machines, which is physically very demanding on the one hand and can be time-consuming on the other. 8-10 treatments are applied, which gives a rhythm of about 10 days for the repetitive spraying with pesticides. A mildew attack does not only destroy the actual harvest in the worst case, it even has negative effects for the following years.
On very steep slopes, there is a big risk of accidents with the vehicles, as these can overturn. Numerous deaths from the past years testify to this.
For the winegrowers, treating the vines from the air with an agricultural drone brings clear operational advantages. Some winegrowers have already had some experience with this and there is a certain acceptance of the new technology.

5. Conclusion
A lot of vines are sprayed in Switzerland with drones. This client is special because we spray young plants for him, which are especially sensitive and valuable. Manual spraying is done with tractor, but they have lots of problems in steep hills.
The drone spraying application is very dense monitored by the customer who is a country widely-known specialist for young vines. He built up special landing platforms for the spraying drone.
Spraying in vines is mostly for preventing against the disease happening.
Downey mildew happens if no spraying.
Healthy plants after spraying
The client actively compares drone spraying with earlier tractor spraying. The client is happy with drone spraying, reasons:
No personal contact to pesticides
Same speed in flat terrain as tractor, however, in steep terrain the DJI Agras has a much higher efficiency.
Warm prompt: The content and parameters provided here are just for reference. You should adjust the operation mode and the parameters and use a correct way to spray your field according to the different weather, the crop characters, the habit or history of using chemicals (you could change other chemicals in case that the resistance occurs), etc. If you are not sure what operation parameters you will choose or not sure about the spraying efficacy, then you should firstly do a small plot test in this field before a big area spray.
Farmers around the world already rely on DJI equipment to plan, manage crop health, and identify issues before they impact bottom lines. Drones have become a necessary and important tool for boosting efficiency and maximizing yields. The latest addition to our agriculture fleet is truly game-changing: Enhanced multispectral data from a platform that’s capable of much more besides.
Here are the top eight features of the new Mavic 3M.
The world’s smallest 4-band multispectral drone camera
Multispectral imagery gives agriculture professionals a way to see the invisible and remove the guesswork from day-to-day operations. By having access to data across specific parts of the electromagnetic spectrum, farmers can build smarter workflows that lower costs, use resources more efficiently, and ultimately maximize yields.
The Mavic 3M has a built-in sensor array that combines Green, Red, Red Edge, and Near Infrared sensors to support the NDVI, GNDVI, and NDRE vegetation indexes.
All three provide powerful insights for farmers. The NDVI makes it possible to detect plants under stress, differentiate between crops, and determine at which stage they are in their growing cycle. The NDRE index provides insights on chlorophyll content in leaves, and the GNDVI is useful for estimating photosynthetic activity, as well as water and nitrogen content in the plant canopy.
Pilots can harness multispectral insights in real-time, thanks to a new feature that shows you live vegetation indices in split-screen alongside the visual feed.
All of the above is enabled by DJI’s latest: the smallest 4-band multispectral camera in the world.
A sunlight sensor for more consistent data
When assessing agricultural data over time, changes in the weather from day to day can interfere with the clarity of your NDVI results. The Mavic 3M has a built-in Incident Light Sensor on the back of its airframe that works to mitigate this. It takes solar irradiance readings that can be used to calibrate and normalize your multispectral data in post-processing. By adjusting for sunlight levels, you get more accurate NDVI results and better data, no matter the weather or season.
An advanced visual camera for efficient surveying and mapping
Beyond its multispectral capabilities, the Mavic 3M has a visual camera that’s been developed to take agriculture and mapping workflows to new heights. With its huge 4/3 CMOS and 20MP image sensor, a mechanical shutter, and 0.7-second interval shooting, everything is geared towards rapid aerial surveys and data quality. Pair this with a 43-minute flight flight time, the Mavic 3M can capture data across up to 2 square kilometers in a single flight.
We see these speedy aerial surveys as the perfect partner for multispectral data gathering. For the first time, a single platform can be used to generate both high-quality photogrammetry and multispectral assets, making it cheaper and easier than ever to set up a digital twin of your farm and overlay NDVI data over time.
We also know that agricultural professionals work around the clock. The Mavic 3M’s visual camera is designed to be just as flexible, with 3.3μm pixels and improved low-light software that offers superb performance in dim conditions. Ultimately, the Mavic 3M is about working faster and smarter. With rapid surveys and features designed to mitigate low and inconsistent light, your operational window is wider than ever.
RTK compatibility for precision surveys
When you’re creating photogrammetry assets and gathering multispectral data, precision is everything. The M3M is compatible with our RTK accessory to allow agricultural professionals to conduct surveys with care, efficiency and – crucially – without the need for Ground Control Points.
Whether you want to level land, spray crops, gather multispectral data, or optimize harvesting lines, working with centimeter-level accuracy can make a huge difference to the quality of your insights and the detail of your planning. In turn, this will feed into the efficiency of day-to-day operations, with fewer mistakes and marginal gains across the board.
Setting the standard for safety and stability
The Mavic 3M harnesses the latest in DJI’s safety and transmission technology to reduce the risk of accidents.
Chief among them is state-of-the-art obstacle sensing and navigation powered by our Advanced Pilot Assistance System (APAS 5.0). Data from six vision and two wide-angle sensors are assessed in real-time to detect obstacles in every direction and – when using Avoid mode – reroute your flight path accordingly. APAS 5.0 also powers the Mavic 3M’s advanced Return To Home feature, which optimizes your flight path to preserve battery and get your aircraft home safe and sound at the touch of a button.
Last but not least from a safety perspective: As with all of DJI’s latest enterprise platforms, the Mavic 3M’s built-in AirSense system provides an early warning of nearby crewed aircraft transmitting ADS-B signals.
Your connection to the drone is just as stable as its flight. The Mavic 3M comes with DJI’s O3 transmission technology. It sets the standard for video and control stability and provides a reliable link between pilot and aircraft.
A compact platform for rapid deployment
Agriculture professionals are used to working with heavy machinery, but gathering data doesn’t have to be that way. The Mavic 3M is small, compact, and foldable – easily sliding into a backpack for easy transportation from one site to another.
You can carry the Mavic 3M in one hand and take off in a matter of seconds. This is true portability alongside the smallest multispectral camera on the market. There’s no longer a choice to be made between convenience, capability, and performance. With the Mavic 3M, you can have it all.
Full compatibility with DJI’s SmartFarm App and DJI Terra
The Mavic 3 Multispectral is fully compatible with the DJI SmartFarm app, allowing agriculture professionals to coordinate any data gathered with spraying and spreading operations.
SmartFarm comes with a range of features for streamlined workflows, including intuitive mission planning, a full fleet overview, field management, data assessment, and effortless collaboration between teams.
We’re keenly aware that no farm is the same and that, in particular, not all farms are on flat terrain. That’s why the Mavic 3M offers Terrain Follow so you can maintain an even altitude as you fly a survey mission across varying terrain. By smoothly adjusting according to the terrain, you can secure the integrity of your data while it’s gathered, without having to account for any differences in post-processing.
For situations when you weren’t able to import a DSM or local elevation data pre-flight, the Mavic 3M’s collision avoidance sensors can take over by detecting the ground below and automatically adjusting flight height accordingly.
Cloud API and ecosystem support
If you would like to work with or build a custom solution with Mavic 3M, you can do so with DJI’s Cloud API. It allows developers to connect to the Mavic 3M’s hardware, video feed, and photo data in third-party software.
With Mobile SDK and Payload SDK, developers can expand the applications of Mavic 3M thanks to its top accessory port.
Redefining drone multispectral
The Mavic 3M is compact and portable but offers revolutionary capabilities for agricultural and surveying professionals. This drone redefines industry standards for small multispectral tools, and has a little something for everyone.
DJI AG drones help corn to prevent diseases and increase yield in the later stage
In the past two years, with the rising price of corn, many farmers turned to corn planting. However, although corn is a high-yielding crop, it is often difficult for growers to cultivate it to a peak yield. In order to improve the quality and yield of corn, in addition to selecting high-quality varieties, timely sowing, and strengthening field management, there is also a very key element, which is to strengthen the control of diseases and insect pests and nutritional supplements in the middle and late stages of corn to reduce empty stalks and bald ears.
Right now is the flowering stage of corn, which is also a critical period for corn growth. Due to the low temperature and frequent rains in this area in the early stage of this year, the corn was flooded, and the entire growth cycle of corn was forced to be delayed. In addition, the weather is humid, and red spiders, aphids, and other diseases and insect pests also occur frequently. If the disease prevention and yield increase are not timely, corn will face serious production reduction or even no harvest.
“Almost 5x return”
The local agricultural science and technology crop management team set up demonstration fields and performed yield enhancement and sterilization operations on more than 50 Acres of corn fields.
The team said they have been spraying corn booster packs with drones since 2019. “If the management is carried out in the later stage, the yield can be increased by 540KG per acre. According to the current corn purchase price and input cost, it can almost bring a return of 5 times.”
After 15 days of operation, the demonstration field has been clearly differentiated. “This is the difference between spraying and no spraying. You can see the difference in the autumn harvest. The yellowing corn field next to it has not been treated to prevent diseases and increase production, and the loss of water and fertilizer nutrients may cause the corn to not be fully ripe.
As the frost began to fall at the end of September, if the corn could not be fully ripened in time and the weight could not rise, the harvest would inevitably be affected. He said.
15 days after the operation
“Spraying is really different from not spraying, and the money is not in vanish.” Through this comparative experiment, farmers are very satisfied with the operation effect of DJI agricultural drones.
Can’t get off the ground?
A new tool for “over the air” management
Since the corn ridges have been closed in the later stage, and the rain is frequent this year, traditional tractors and elevated vehicles cannot enter the corn fields, otherwise, it will cause problems such as crushing seedlings and trapping vehicles, while the use of drones is not restricted by terrain.
Drones can reduce costs while increasing efficiency and quality by 30%.
Corn disease prevention and yield increase
Many farmers do not have awareness of later investment, thinking that the appearance of corn looks similar, but the difference can be seen when the autumn harvest is weighed. The corn that is growing well has large cob, full grain, and no bald tip.

The Tanaka in this operation was endangered by whitefly and cutworm. Therefore, carbosulfan is used to control aphids and whitefly. Emamectin has high activity against lepidopteran pests and is used to control cutworms. At the same time, two broad-spectrum fungicides, difenoconazole, and myclobutanil, were used to prevent the occurrence of powdery mildew.
Pumpkin Leaves
Pumpkin powdery mildew is the most common and serious disease of pumpkin, which mainly damages leaves. Serious leaf yellowing or even scorch, affecting the fruit of the pumpkin. The incidence of pumpkin powdery mildew peaks when high temperature, high humidity and high temperature and dryness alternate. At the same time, the disease is prone to or heavier in fields where nitrogen fertilizers such as urea are applied more, planted too densely, and humid.
First, you got the farm multispectural map out (after uploading all the photos, we used about 10 minutes to generate this VR map). This is how it looks in DJI’s Terra software.
P4M is an integrated high-precision multispectral imaging drone launched by DJI in 2019. It is mainly used to monitor the growth and health of crops, and you can accurately see the crop conditions and water stress map through the software.
You can shift the RGB image to any of these spectral images easily.
You can zoom in to see the details for unhealthy areas. In some software, red means death, in DJI Terra software, the areas in red are the areas with the most biomass and vice versa. We usually use this map to directly judge the areas that need to be inspected and judged. At the same time, with Terra software, you can directly create variable job maps, whether spreading fertilizers or spraying liquids.
Then you can select the problem area and do VR application.
The above is our cloud version Terra software, DJI is going to have an English version by the end of this year.
The desktop version of Terra software has all kinds of language selections.
You can use google translate to read Chinese on screen for now.
This is a total of 0.15 acres. You can make 5 levels in total, in this software, we choose 2 layers so that you can see the light green area is the place we need to take care of. So that you can input your rate accordingly.
This VR map can be read directly by the DJI Agras drone for the target spray/seeding/replanting.
You can also adjust the VR ratio by sliding the bar area.
Elevation map
The software can also easily analyze the high and low terrain so that you can better manage water stress areas.
Please let us know if there are any questions you might have about these drones, we’d be glad to help!
Using drones to pollinate pear trees can not only improve the growth of crops but also promote the germination of pollen and the growth of pollen tubes, thereby increasing the rate of speed setting and fruit set.
In the past, in addition to bee pollination, there was artificially assisted pollination, but it was time-consuming, labor-intensive, costly, and uneven. The flowering period of pear trees is short. Normally, 40% of the flowers are pollinated for the first time, and 70% of the flowers are pollinated for the second time. However, due to the low efficiency of artificial pollination, the whole process can only be completed once, which greatly affects the fruit setting rate.
Nowadays, the use of drones for liquid pollination has become the choice of more and more farmers due to its high efficiency, high fruit set, and high yield.
The DJI agricultural drone custom farming team in northern China has been the first to use DJI plant protection drones to carry out liquid pollination of pear trees since 2019.
Due to its high efficiency, uniformity, and pollen saving, the team quickly opened the drone service market for pear tree pollination.
Two people a day and one drone can operate 40Acres orchards, which greatly improves the operation efficiency. From April 4th to 13th this year, they invested a total of 15 T-series DJI agriculture drones to pollinate 1700Acres pear trees.
“We used T16 for pollination in 2019, and many orchard farmers asked us to use DJI drones for pollination this year.”
Precautions for configuring pollen solution
1- Purified water is required to ensure the quality of the water.
2- Add sugar to the water to provide nutrients to the pollen, ensure the activity of the pollen, increase the viscosity of the pollen, and improve the adhesion rate.
3- It needs to be prepared and used immediately to avoid pollen inactivation.

Tip: When working on pear trees, you should avoid the high-temperature time, between 6-25 °C, to ensure the pollination effect.
Compared with manual work, drones pollinating fruit trees can not only help local growers reduce costs, ensure efficient pollination rates, improve the yield and quality of pears, but also drive local employment rates.
DJI Agras drone unboxing and precautions for users in Canada
Congratulations on your purchase of the first/first set of DJI Agriculture 2-in-1 spraying/spreading drones, I hope it will be your good helper and help your agricultural business shine more brightly. How do we debug, and take off? Here are some small details to share with you.
1. Unpacking
Carefully lift the whole machine out of the box, find the remote control, and check the power of the remote control. After starting the remote control, follow the prompt steps to register the device. For customers who have purchased multiple drones, the registered user names must be the same to facilitate group flight settings.
2. Charger precautions
The T20 can be charged normally on the walls of the farm shop (say where you use the hairdryer)
The T30 uses a high-power charger with a rated power of 7200W, which cannot be directly charged in a single wall socket. If using two power cords to connect to the wall for charging, make sure that the two plugs are connected to two separate breakers in the electrical box, or you need to use an adapter power supply (greater than 9000W).
3. Connect the drone Move the device to an open and unobstructed place outdoors for connection. 1) Start the remote control first 2) Connect the drone as required by the remote control 3) After the connection is successful, perform the lift operation of the aircraft (up and down is lift, left and right is self-rotation) (left button).
4) After completion, rise to about 3 meters, 10 meters away, first push the rod slightly upwards, push up to move forward, downwards to retreat, and then perform lateral movement training, move left to move left, and move right to move right (right button).
Never fly the drone towards you, the direction of your remote controller and the nose of the drone must be the same（the rare light is green colour）. The flight speed of the plane is very fast, if you are facing yourself but the speed is not controlled well, you may hurt yourself.
After the drone takes off, it must maintain a one-button operation, that is to say, only give the drone one command at a time. You can’t let it go up and push the button to make it go forward at the same time. If the data cannot be processed, accidents will happen.
5) Press the “H” key, the drone will start to automatically return to the take-off point. The drone will hover 3 meters above the take-off point, and you can choose to land automatically or manually.
4. RTK connection *** Move the device to an open and unobstructed place outdoors for connection. 1) Start the remote control first 2) Select RTK+Aircraft mode on the remote control and complete it in four steps. Start RTK mobile station, keep low frequency and slow flash Press the M key and press next on the remote On the remote control, make sure that the remote control is connected to the RTK pole Turn on the aircraft to connect the remote controller to the aircraft, it will display the connection RTK mobile station, you need to wait patiently for about 20 seconds. At this time, the remote controller will display the remote controller, and the connection between the RTK stick and the aircraft is completed.
5. Map flight planning With the RTK stick connected, let the aircraft fly around the target area with no load.
6. Precautions for operation
When editing the plan, be sure to edit the flight path from near to far (allowing the pilot and drone to have sufficient warm-up time).
After the drone operation is completed, it will return to the take-off point. People and pets must not stand in this place.
When the drone is working in the field, it is absolutely forbidden to patrol the field under the aircraft to observe the operation effect.
7. The sequence of battery replacement and dosing
Change the battery first, then change the water tank or add the mixed solution, which can effectively prevent the mixed solution or fertilizer from entering the distribution board, and avoid the corrosion and oxidation of pesticides and fertilizers on the distribution board. Use a funnel as much as possible when adding the mixture to avoid waste of liquid and corrosion of the fuselage, distribution board, and radar
At the end of each day, use a brush dipped in 95% alcohol to clean the distribution board to keep it clean, and free of black oxide and green patina to ensure efficient operation. For the battery socket, it should be cleaned weekly with a cotton swab dipped in 95% alcohol to remove black and green oxides and avoid bad conditions such as battery certification failure.
When the battery is about to run out, the drone must return in time when it is required to return.
The drone’s smart system will calculate the amount of power needed to return it, and if you ignore the alarm it will crash the drone.
8. Precautions for the use of spraying system
The water tank filter of the T20 needs to be cleaned if it feels clogged. At the bottom of the tank, just pull it out.
T30 adopts the plunger pump design, which has the advantages of large flow and high efficiency, but the plunger pump also has the characteristics of not idling and has certain requirements for the type of liquid. equivalent dosage form.
9. The following points should be paid attention to in daily work:
After each operation, add clean water (add a little detergent) to the medicine box and start spraying to flush the spraying system.
It must be ensured that the liquid medicine is effectively filtered, and the sediment in the liquid medicine must not be poured directly into the medicine box. The filter at the bottom of the medicine box and the filter at the mouth of the medicine box must be cleaned regularly to ensure smoothness.
After the T30 plunger pump has been running for 300 hours, the lubricating oil should be replaced. The capacity is 30ML, and it is preferred to use high-quality lubricating oil, or gear and bearing lubricating oil with similar performance.
10. Maintenance after the operation
If it is spraying liquid, be sure to fill it up with clean water after the end of the day’s work, and open the water to the maximum for spraying and flushing the pipeline. three times.
1) The battery must be removed before cleaning the body;
2) Install the battery after the distribution board is completely dry;
3) Do not use a high-pressure water gun to wash the motor cover, try to clean it with a rag.
After using the viscous agent, it is recommended to clean the filter to prevent clogging and leakage.
If it is a spreading system, it is recommended to simply disassemble and clean the spreading system after each spreading operation, and clean the residual fertilizer in the material box, which can effectively prevent the fertilizer from corroding and prolong the service life.
If in daily use, after the empty water tank is filled with water, the remaining amount of medicine shows 0L, it is recommended to clean the single-point level gauge and check whether the level gauge is installed properly.
The nozzle has a huge impact on the performance of the work, so it should be ensured that it is in good condition. In the process of daily spraying operation, it may be blocked by powder. At this time, brushes such as toothbrushes must be used for cleaning. Never use metal such as steel wire for cleaning, which will cause damage to the nozzle and reduce the operation effect.
Please always keep safety in mind and never underestimate the power of naturalwind and propellers.
After long-term and high-intensity operations, some parts of agricultural drones may experience aging and damage, which will affect the efficiency and effectiveness of operations, and even bring security risks.
It is recommended to conduct a comprehensive inspection of the plant protection drone for about one month of high-intensity operation to ensure the stability and reliability of the plant protection drone.
1. Inspection of the sprinkler system
Remove the water tank and observe whether the sealing ring is greatly deformed or the sealing surface is damaged. If so, please replace it immediately, otherwise, it will cause failures such as air intake.
Remove the screw cap at the bottom of the water tank, remove the filter screen and the corresponding sealing ring, check whether the filter screen is blocked, and clean the filter screen.
Liquid box filter and rubber gasket
Check the two-level gauges inside the tank, clean with clean water, and check for corrosion.
Check whether the pipe joints of the spraying system (water tank, water pump, flow meter, etc.) are loose or not and whether the pipes are broken.
Observe whether the pressure relief valve sees water. If there is a problem, replace the sealing gaskets in two places in time.
Check the atomization of the nozzle. If the atomization is poor, clean it thoroughly or replace it with a new nozzle.

2. Maintenance and inspection of power system
a) propeller
Clean the propeller with a well-wrung, damp cloth, grasp the end of the blade, lift the blade down or up, and inspect the edge of the propeller for cracks.
Check whether the propeller gasket is worn. If the wear is serious, please replace it with a new propeller gasket in time.
Rotate the propeller to check if the propeller clamp is loose. If it is loose, use an M4 screwdriver to tighten the blade fixing screw.
b) Motor
Rotate the rotor of the motor and check whether the motor is stuck or locked.
Pull the motor rotor slightly vertically upwards to check for looseness of the motor rotor.
Shake the motor horizontally from side to side to check whether the connection between the motor and the motor base and the machine arm is firm. It is recommended to remove the black motor protective cover, check whether the two screws fixing the motor base are loose and whether the limit module between the motor base and the machine arm is worn.
3. Maintenance and inspection of the fuselage
Check whether the arm is cracked or deformed, unfold the arm, and check whether the threads of the sleeve and the locking position are worn.
Check whether the RTK antenna and SDR antenna are fastened and whether the RTK module above the machine head is loose.
Check the air filter cover in front of the upper cover of the aircraft and clean it in time.
Check whether the tripod and the fuselage frame are loose.
Check whether the radar casing is damaged and whether the radar bracket is firmly installed.
4. Remote control maintenance and inspection
Remote control suspension: The remote control can be hung under the aircraft, but it is necessary to ensure that the aircraft does not penetrate liquid, so as to avoid liquid infiltration into the remote control and cause damage.
Remote control cleaning: The remote control needs to be wiped regularly to avoid the accumulation of dust, etc., to ensure a clean appearance of the remote control.
Remote control antenna: When the remote control is not in use, the remote control antenna needs to be folded and stored to avoid breaking the antenna.
Remote control external battery: Check whether there is mixed liquid and dust at the interface between the remote control external battery and the remote control. If so, please clean it up in time. When the external battery of the remote control is stored, it needs to be stored in two cells. It is forbidden to store it with full or low power.

5. Battery Check
Check whether the appearance of the battery is normal. If the casing is damaged, deformed, or leaks, please contact our after-sales service and do not use it again.
Check the metal reeds of the battery and battery holder. If there is a little blackening, wipe it with alcohol in time. If it is black in a large area, please replace it in time. The battery is not waterproof, so do not wash it directly with water or soak it in water.
Batteries and Battery Holders
When working, the operator should return to the drone in time for charging when the battery has 30% remaining power.
If you continue to use it and over-discharge many times, it will seriously affect the battery life.
6. Inspection of the spreading system
Check whether the connection between the tank and the spreader is loose if there is a lock key for the replacement box.
Separate the tank from the spreader, check the parts of the spreader, use a soft brush to clean the surface attachments, and do not rinse directly with clean water.
Detach the spreader plate and check the plate. If there is obvious wear and tear, please replace the spreading disc in time.
Comparison of old and new spreading plate
The spreading system is factory calibrated and ready for immediate use. If the following conditions occur during use, the user needs to calibrate by himself:
The door does not fully open or close;
The blanking rate deviates from the expected value;
App false alarm and no material alarm.
Calibration steps: Enter the App operation interface – setting options – seeding system, click calibration in the seeding system settings, and then wait for the calibration to complete. If the calibration fails, please try again.
Agricultural drones with battery storage
1. Agricultural drone storage
Agricultural drones should be stored indoors in a ventilated, dry and protected place from direct sunlight. The temperature in the storage room is within the range of 18-25°C, not higher than 30°C. Do not place agricultural drones in dark, damp corners or store them in the open air.
In addition, it is necessary to ensure that the storage environment is free from pests and rodents, and it cannot be stacked with highly corrosive items such as fertilizers and pesticides, so as to prevent the plant protection drone from being rusted and damaged.
2. Battery Storage
If the battery prompts low power after the operation, it needs to be charged until the battery indicator is two to two and a half bars and stored, otherwise the battery may be damaged if stored for a long time.
The storage environment of lithium batteries should be kept dry. Do not place the battery in water or where it may leak, and do not place the battery near heat sources, such as in direct sunlight or in a car on a hot day, a fire, or a heating stove.
If the battery is to be stored for a long time (more than 3 months), store the battery in a dry and ventilated place, away from heat sources, in a special explosion-proof cabinet. And recharge and discharge every 3 months or so to keep the battery active. Storing the battery in sub-zero temperatures can result in impaired battery performance.
The farmland plant protection operation environment is complex, and it is used every day when the operation period is tense. Therefore, it is very important to maintain the agricultural drone in your hand, and you can count on it to change to a better house.

It’s a great honour to participate in the 46th annual tomato day in Chatham, ON.
Red Gold Farm shared that “When Dad says its too muddy to go to the fields…”
We all want to succeed, we don’t want to fail, we all want to hurry, we don’t want loss. To judge whether an agricultural tool is useful or not, it is to see if it can bring us value and solve problems.
We shared the drone technology, many people think, what can such a small tank do? It’s not enough for me to spray a few feet of the field.
How are agriculture drones helping our large size farmland?
Actually, the drone is not designed for large-scale farming purposes. It is an additional tool to the toolbox. It uses only 10% around mixture while saving 30-50% of chemicals, the application of multispectral drones the variable-rate help you only sprays the problem areas and saves another 20~30%, save 80~90% of water, and no annual fee for RTK equipment.
The work efficiency is about 40 acres/hour at a 5L/acre rate for the Agras T30, if you apply 7-9L/acre, it will slow down the total work efficiency. The battery is using premium material, rechargeable, no need to cool down, you can charge directly, every T30 equipped with 3 batteries so that you can continue to work.
It’s good to use for irregular terrain and wetland, the spray width can be adjusted from 4M-9M from the remote controller.
Is a battery-operated agriculture drone an option?
As fuel prices rise, so does the cost of agriculture. If we want to reduce the input cost of agriculture and increase the profit of crops, we must consider all aspects. The high-efficiency drone battery can be repeatedly charged and used, which can help reduce the use of diesel by 60~70% for the same acres of operation.
How did we get this number out:
The 2 in 1 spraying and spreading drone, Agras T30’s new smart battery guarantees 1,000 internal cycles, operates up to 5,000 acres( fuel consumption is: 0.6L fuel/battery/5acres x 1000 internal cycles=600L), that means you use 600L fuel can operate up to 5,000 acres.
10-12 minutes to complete the ultra-fast charging, only 3 sets of smart batteries and a charger can be used for uninterrupted operation.
There’s also an DJI Agras user talked about this saving, in this article, link, click here.
Is a battery-operated agriculture drone an option?
Many people want high-capacity, wide-wing drones to do farm work. We talked to DJI about it, they could make bigger drones, but why not? As there’re many factors to be considered and tested by the engineers and research teams to test with all the aspects step by step, drift control, whether the downforce wind pressure will damage the crops, safety considerations. But the good thing is that this technology allows you to use a remote to operate 3 drones to work together if you have a large field to deal with.
Drone tech is also helping to minimize soil disturbance, targets precisely, increases work efficiency, and ensures people’s health.
We cooperate with Corteva Agriscience in 2021 by using DJI Agras T20 to test fungicide Acapela on their soybean field for white mold prevention. Corteva stated that The good news from the drone operation is that there is a clear plant health effect of the spray.
(Photo provided from Corteva Agriscience)
All of these need strict tests in the laboratories and in the field as well. DJI agriculture drone due to its cutting edge knowledge and safety performance has been widely recognized by farmers around the world as a qualified and responsible drone manufacturing company.
Bayer in the US also tested soybeans and corn last year, confirming the effectiveness of around 10% mixture for the same yield as ground equipment. Watch their video Applying fungicide with UAVs, click here.
A grower shares what he has to say about Bayer’s spraying drone test field “They were super impressed with spray coverage and the most healthy and uniform field they saw all year. I find it hard to think 2 GPA will do the same as me soaking corn plant from tassel to just below cob, that is 5-6’ of soaking”
For example, some places are relatively wet after rain/snowmelt, and large-scale equipment cannot enter. At the same time, there are often places, edges, corners that cannot be sprayed, which are also the places that outbreak of pests and diseases that spread to the interior field. The sprayer drone is a just-right tool to help with these concerns.
EU plans to reduce pesticides by 50%. Hungary tested weeding by using DJI Agras drones with P4M together last season which proves to save nearly 70% of chemicals.
Here’s the link to the article: Spot Spraying With Drones: Using Technology to Cut Herbicide Use in Half
Chile also tech Biosmart by using DJI Agras drones on the sweet cherry trees, which shows that instead of 800L-1200L of water, it only uses 30L/Ha.
Before DJI releases the agriculture drone to the market, they have undergone rigorous coverage testing and particle size testing.
They are not only testing the front of the leaves’ uniform coverage but also the back of the leaves, as they stated that the back of the leaves are the places where the bugs are hidden. The drone needs to be able to spray the back of the leaves to kill those bugs.
How to achieve a closed-loop precision agriculture solution?
When we do farm work, we want accurate forecasts to deal with pests and diseases.
DJI drones operate in the same platform which greatly reduces your downloading time and generates variable rate map time from 4-5 hours to 15-20 minutes, which greatly reduced the risk on yield.
DJI P4M multispectral drone is an integrated device that can be easily brought to the farmland to monitor the chlorophyll index of crops from time to time.
Agronomists can help farmers make timely judgments and treatment on the field conditions based on the specific problems of the field designated by the images, thereby avoiding losses and increasing yields.
Spring is here， do you have the drone ready to take care of your 2022 season?
And also, many places are starting to use the DJI P4M multispectral drone to scout some winter wheat fields now. Agronomists instruct farmers in variable spreading operations based on crop growth. Save time and cost.
Welcome to give us a call and we would be glad to help your farm select the right agriculture drones, or you are welcome to make an appointment to try ag drone services.

Dimethomorph is a specific oomycete fungicide with systemic therapeutic properties and can be used to control downy mildew and late blight. Fluazinam is a broad-spectrum and efficient protective fungicide. Very effective against Alternaria, Phytophthora, Plasmopara, Sclerotinia, and Sclerotinia.
Chlorpyrifos is a broad-spectrum organophosphorus insecticide with stomach and contact effects and was used in this operation to control underground pests. The special adjuvant for the red swift low-volume spray is a special adjuvant for flight control, which can improve the effect of flight control.
Introduction to Pests and Diseases
Potato late blight is a worldwide disease with a high probability of occurrence on potatoes.
Caused by Phytophthora infestans, it is a devastating oomycete disease that causes leaf death and tuber rot in potatoes.
The infected leaves first develop water-soaked green-brown spots on the leaf tips or leaf margins, with a light green halo around the lesions. When the humidity is high, the lesions rapidly expand, turn brown, and produce a circle of white mold; when dry, the lesions turn brown Dry, brittle, and easy to crack, with no white mold, and slow expansion.
Stems or petioles are infected with brown streaks. The severely diseased leaves droop and curl, and eventually, the whole plant is black and rotted, and the whole field is scorched and rotten.
Tubers infected with primary brown or purple-brown large lesions, slightly sunken, and the subcutaneous potato flesh of the diseased part is also brown, and slowly expands or rots around. The disease is more severe in rainy years when the air is humid or warm and foggy.
Common underground pests that damage potatoes include needle worms, cutworms, and grubs.
The golden needle insect mainly bores the buds, roots, and underground stems of potatoes, causing the seedlings to gradually wilt or die. Drilling into the tuber creates tunnels and reduces quality.
Cutworm is a lepidopteran larva, which mainly harms potato seedlings. It bites the seedlings close to the ground, causing the whole seedling to die. The young larvae also bite the tender leaves, causing the leaves to have nicks and holes.
The grub, also called the ground silkworm, is the larva of the beetle. It mainly damages underground tender roots and tubers, causing above-ground stems and leaves to die due to insufficient nutrition and water supply.
After the tubers are bored, they cause loss of quality or cause rot. Adult insects can also fly onto plants to feed on leaves.
When the spring flowers bloom, the wheat begins to enter the greening period. The leaves gradually turn from yellow to green. The greening and jointing period is the core key period of wheat growth.
In February, the average temperature in Shandong is above 8℃. The local drone Custom Farming Team seized the good weather and started weeding operations one after another.

Ruichao wheat (300 grams of Ruichao wheat + 900 ml of special additives for Ruichao wheat), 75% fluoxuron-methyl water-dispersible granules, Guanyun foliar fertilizer, 28-homobrassin.
The main reasons for the selection of Ruichao wheat herbicide this time are: the weeds in the wheat field in this area are mainly broad-leaved weeds, Artemisia spp. Fluoxasulfone is effective in controlling grass weeds.
The combination of two herbicides can control grass and broadleaf weeds at the same time. Adding Guanyun foliar fertilizer and 28-high brassin can increase nutrition and promote the growth of wheat.
Spraying effect: 10 days after spraying, the grass in the wheat field began to turn yellow.
In the winter wheat field after spraying, it can be seen that the weeds are basically wilted and twisted, the leaves are yellow, and some have withered, but the growth of the wheat is not affected. This work has met the prevention and control requirements.
Affected by the drought, there have been outbreaks of corn Western bean cutworm in many places in northwest China. Western bean cutworm is a migratory pest with the characteristics of sudden and gluttony. The corn Western bean cutworm gluttonously eats corn leaves as larvae. In severe cases, the leaves are eaten up to form bare stems, resulting in severe yield reduction or even no harvest, affecting crop yield.
“Seeing that the corn is about to be harvested, but now the corn leaves are almost all eaten by insects.” At first, the farmers did not take it seriously. Within a few days, the corn was almost eaten into “bare rods”. The farmers said that because of the continuous drought, This kind of bug reproduces rapidly. If the corn is not treated with pesticides, the corn will soon be eaten to the stalk.
In severe cases, there are more than 200 bugs per 100 plants.” Since July 1, the DJI drone custom farming team has convened a total of 100 pilots, dispatched more than 100 units of DJI Agras drones, and sprayed a total of 115,000 Acres.
One unit of T30 spraying drone can operate about 40 Acres per hour, which is very efficient.
This is the first time for large-scale spraying and control for the outbreak. Generally speaking, there is no problem with scheduling. The overall customer evaluation is very satisfactory, and the control efficiency can reach 85%. “
In some places, farmers couldn’t wait, so we dispatched multiple drones to operate.
We use systemic pesticides, and the effect is very good. During the day, the insects hide in the heart of the corn and come out to feed at night. Therefore, the systemic pesticides can effectively avoid the problem of poor work results during the day.

Farmers are very anxious, and we also hope to complete the control work as soon as possible and efficiently to curb the spread of pests.
Pest Control Effect
Random sampling before spraying showed that, on average, the bugs mortality rate was about 85%.
Result
The spraying proved to be highly effective in controlling pest infections.
The 15 Acres orchards are certified orange demo orchards by Syngenta Group China in Wuming, Guangxi.
Efficiency takes off, drones fly into Syngenta orchards
Since this year, the plant protection management of the demonstration garden has ushered in a new change.
There are more than 5,000 trees in the 15 acres orchard. One DJI T20 and one DJI T30 can complete the pesticide application of the 80-mu orchard in 4 hours.
The biggest feeling that the new changes brought to the technical director of Syngenta Orchard, Mr. Li, was, “The efficiency has improved too much!”
The high efficiency of drone operations is particularly important in the rainy season. From April to August, Wuming has frequent rainfall and a short window period. If it rains within 4 hours of spraying, the efficacy of the chemical will be greatly reduced.
If you use a drone, it only takes half a sunny day to complete all the work. “Technical guide Mr. Li said.
The high efficiency of drones can also effectively solve the current shortage of manpower for orchard spraying and the problem of manpower being easily poisoned.
Canker, leaf miner, T30 control is fast and good
In addition to efficiency, what Mr. Li is most concerned about is the control effect of drones on citrus pests and diseases.
The Syngenta Orange Demonstration field has been exploring the operation plan of combining chemicals and drones. From March to now, a total of 8 flight defenses have been carried out.
“Currently, the use of drones to spray with suitable pesticides can effectively control leaf miners, thrips, aphids, and cankers,” said Ye, technical manager of Syngenta Guangxi.

Canker and leaf miners are common pests and diseases on citrus, which often occur together and spread very fast. Failure to prevent and control them in time will have a great impact on fruit yield and quality.
“This year in Wuming, there was a lot of rain, which coincided with the high incidence of ulcer disease. Some orchards did not catch up with the sunny days and could only watch the ulcers slowly rise, causing great losses.” Li said.
If you use a drone and choose the right pesticide, you can quickly control it in a short window period. The liquid sprayed by DJI T30 can reach the middle and lower layers of the periphery of fruit trees along the wind field, quickly and effectively curbing the spread of canker and leaf miners.
In the picture, the left side of the road is the orchard operated by DJI Agras drones, and the right side is the orchard operated by traditional method. It can be seen that the growth on the left side is significantly better than that on the right side.
Reduce pesticides by 30%, significantly reduce orchard management costs
After experiencing the efficiency and effect of DJI drones in managing orchards, orchard managers also found that this year’s chemical cost was reduced compared with previous years. “After the use of drones, the number of chemicals in the orchard (influenced by the market), the amount of chemicals, and labor costs are all reduced this year.”
According to a rough calculation, for a 15 acres orchard, the use of pesticides by drones is 25%-30% less than that of manual labor, and the water consumption is saved by more than 95%. Overall, it is more cost-effective.
The agriculture drone operation has a strong wind field that uses a small amount of water to drive the liquid to cover the peel and leaves. Compared with the traditional method, which needs to irrigate fruit trees from top to bottom, resulting in waste of liquid medicine, the utilization rate of the chemical in drone operation is higher.
“Traditional spraying uses a lot of water. Last year, it was because the spraying was too intense and the fruit area was too watery, which caused pesticide damage and resulted in a lot of spotted fruit.” Technical guide Li said, “The atomization of the drone is fine, and it is not easy to produce The accumulation of water forms medicinal spots, which can improve the quality of the fruit.” The savings from drones are not only cost but more protection of orchards and the environment.
The Syngenta Orange Demonstration field uses DJI drones for plant protection, which further affirms that drone operation is the future trend. Under the problems of labor shortage, low labor efficiency, and labor safety, we need more excellent chemicals and advanced machines to jointly promote the mechanization and modernization of orchard plant protection.
According to the forecast of the United Nations, with global warming and energy shortage, human beings will face difficulties in food, energy, water, and other aspects.
Efficient, intelligent, green, and sustainable agricultural production methods are imminent.
The stability, load capacity, high-quality image transmission, and battery life of DJI UAVs have been recognized by the global agricultural community.
In 2021, DJI agricultural drones covered 167 Million Acres in operations. This not only drives the improvement of mechanization efficiency but also brings greener production methods for the sustainable development of green ecology.
3.43 million tons of carbon emissions were reduced
Compared with traditional agricultural machinery, drones can reduce carbon emissions by 20.58KG CO2e from the energy consumption of a single Acre. The operation of 167 Million Acres is equivalent to reducing carbon emissions by 3.43 million tons of CO2e.

Equivalent to the water consumption of 527.2Million residents in one-year
DJI Agriculture drones are protecting the earth, from now on.
It is becoming more and more common for agronomists to equip drones to monitor and manage crops in the field, but people are not very familiar with drones and accompanying software. We’ve had a lot of calls over the past few months asking about multispectral cameras, drones, software, download times, companion apps, and more.
We would like to share some agricultural drone information with you to help agronomists understand what drones are needed to effectively assist their work in the field.
Let’s take a look at a Multispectral drone – DJI P4M
In daily agricultural management, we usually need to use multi-spectral technology to monitor the growth and health conditions of crops at various stages in combination with actual production management, so that farmers and agronomists can make timely judgments and optimal decisions over there.
The DJI P4M multispectral drone is mainly used for crop emergence monitoring, nutrition monitoring, weed monitoring, land level inspection, etc. Monitoring results are combined with DJI’s precision agriculture drone solutions, from identifying crop health at each stage to precise application rates and crop protection efforts.
The DJI P4M and DJI Agras drones can be operated on the same software platform (DJI Terra software), and the NDVI and RGB images will be displayed in real-time on your iPhone or iPad while you standing in the field. Precision crop prescription maps can be downloaded in under 10 minutes, allowing your customers to make decisions before they face challenges.
This is why DJI’s precision agriculture drone equipment is so popular with agronomists and agricultural industries all over the world.
Simple, easy to use, integrated, powerful, and safe. This is what they call DJI ag drones are the only precision agriculture drone equipment in the world that can operate in a closed-loop and brings lots of conveniences.
This software is free to use for the whole first year, so you can experience it as much as you like. lol
Potato late blight, caused by Phytophthora infestans, is a devastating oomycete disease that causes leaf death and tuber rot in potatoes.
Potato late blight
Late blight
The leaves are infected with water-soaked green-brown spots first on the leaf tips or leaf margins, with a light green halo around the lesions. When the humidity is high, the lesions rapidly expand and turn brown, and a circle of white molds, namely cysts and spores, is formed. The sac, especially on the back of the leaf, is most obvious; when the disease is dry, the lesions become brown and dry, brittle and easy to crack, no white mold is seen, and the expansion speed is slowed down, and the stem or petiole is infected with brown streaks.
The severely diseased leaves droop and curl, and eventually, the whole plant is black and rotted, and the whole field is scorched and rotten. Potato late blight occurs all over the world and typically reduces yields by 30% in epidemic years.

After spraying, growers reported that there was basically no late blight in potato fields, and the preventive effect was outstanding.
UAV plant protection operations have brought us more convenience, allowing people to fully appreciate the power of technology. With the advancement of technology, traditional production methods will change, and more efficient and convenient production tools will further improve production efficiency.
It contains prostaglandin A, which can reduce peripheral vascular resistance and blood viscosity. It can be used to lower blood pressure, refresh the mind, relieve stress, and prevent colds.
Onion
What we usually eat is the stem of an onion. Onions do not have taproots, but mainly string-shaped fibrous roots. During the reproductive growth period, onions will bloom and bear fruit. The flowers of onions are generally about 1 meter high in the air, cylindrical, and swollen below the middle. The inflorescences are umbel-shaped, many and dense, and the pollen is white.

Common diseases of onion
Downy mildew can occur at all stages from plant seedlings to harvesting, and adult plants are severely damaged. It mainly damages the leaves and develops from the base to the upper leaves. When the air is humid, the back of the leaves produces a frosty mold layer, which can sometimes spread to the leaf surface. In the later stage, the lesions were withered and contiguous and were yellowish-brown.
The soft rot lesions spread upward from the petiole in sheets, and eventually, the leaf bulbs rot from the outside to the inside. When expanding upward from the root, the leaf ball rots from the inside to the outside, and it is milky yellow muddy, and smelly. Because the tissues of the roots and stem bases become brittle after being damaged, the leaf balls are easy to fall off, and they fall when touched. During storage, the leaf bulbs are easy to fall off or rot and the veins of the affected leaves turn dark brown.
Medication Information
In order to prevent the occurrence of diseases, after consultation with pesticide experts, the medication is as follows:
Incidence rate before spraying = 11 shots of diseased seedlings / 200 shots of inspected seedlings × 100% = 5.5%,
Incidence rate after spraying = 0 shots of diseased seedlings / 200 shots of inspected seedlings × 100% = 0%
Disease reduction rate=(5.5%-0%)/5.5%×100%=100%
From the data, it can be seen that this work performed well. The use of drones to carry out plant protection operations on economic crops can ensure the effect and efficiency while avoiding the crushing of crops by machinery entering the field and ensuring farmland output. In this era of rapid development, we look forward to using technology to change the future of agriculture!
Use multi-spectral data to detect the area of weeds, and make timely management decisions. Include forestry and ecology industry in your area, and significantly improve the efficiency of expansion and environmental data acquisition.
Compared with satellites or airplanes, the DJI P4M covers a wide range, and its blue band is between 450±16nm, which has a significant role in water pollution monitoring. It can monitor lakes at a lower cost and higher resolution.
Studies have shown that water bodies have strong reflections in the blue-green band, and impurities such as sediment are sensitive to the blue band. Therefore, using the blue band of the P4M can help assess pollution.
At the same time, water nutrients can increase the chlorophyll content in the water, and there is a correlation between the chlorophyll concentration and the vegetation index. Therefore, the use of multispectral images and advanced products can detect the concentration level of water nutrients, which will help predict the growth of cyanobacteria in the next few days. It can help you to make timely judgments, formulate and implement pollutant interception and treatment plans.
For common water bloom problems such as cyanobacteria, it can also be efficiently identified through the NDVI index. Through the two-dimensional multi-spectral reconstruction, the spatial distribution range and area are further confirmed, and the distribution rules in a specific time are summarized, which provides a timely, effective and objective basis for the ecological analysis of cyanobacteria early warning and management.
Accurate land cover classification and feature identification are essential to natural resource management, investigation, monitoring, and operation. As an important means of low-altitude remote sensing, multi-spectral drones can collect a wealth of information at one time, greatly improving the ability of fine-grained survey and monitoring of natural resources.
Both the visible light and the multi-spectral camera of the Phantom 4 Multi-spectral UAV are 2 million pixels. Real-time images are generated during flight. Users can switch between NDVI images and RGB images in real-time. When the flying altitude is 100 meters, its ground resolution With a rate of 5.3 cm, both RGB images and multi-spectral images have a high spatial resolution, providing high-precision data for the quantitative survey of natural resources.
In the earliest years, everyone knew that DJI’s agricultural drones could directly sow rice seeds. After the rice seedlings emerge, the spreading effect is uniform and the emerging rate of the rice is high. The farmers are very satisfied with the spreading result.
In addition to rice sowing, the DJI drone sowing system is also suitable for sowing clover, cover crops, rye, grass seeds, forest seeds, etc. Now it can successfully sow rapeseed after passing the test
In many rapeseed planting areas, due to the irregular terrain, soil moisture is not suitable for large-scale ground planting machinery. If small seeders are used for direct seeding, there are problems of uneven distribution of rapeseed and uneven emergence rate.
Here we would like to share with you a case study of rapeseed sowing by using DJI Agriculture Drones.
2017 DJI MG1
Spreading parameter test
Due to the small particle size of rapeseed, about 1-2 mm, the flying height should not be too high. Under the premise of ensuring the uniform spread of rapeseed, one of the DJI agricultural drone teams has conducted multiple tests and finally guaranteed that the seeding amount per acre is Under the premise of 2.4-3kg/acre, the best operating parameters have been found.

After finding suitable operating parameters, in order to reassure local users, this team selected 10 acres of experimental fields for field tests.
After using the DJI Agriculture drone spreader for 4 days, the emergence of the rape seedlings made the local agricultural growers quite satisfied with the spreading effect of the DJI Agras spreader, and the task of planting more than 5,000 acres of rape was handed over to this team.
Farmers feedback
After filling the seeds and fertilizer, tap the screen of the remote control, and the drone will sow the seeds on the land according to the set route.
It is very intuitive to see that the drone seeding is not restricted by the terrain, and the spreading accuracy is high and the efficiency is high. Everyone praised again and again: Drone sowing small seeds can be so convenient!
Conclusion
The drone can perform precise seeding according to the area of the plot, avoid omission and duplication.
In the spring of 2020, the temperature was higher, the rainfall amount was larger, and the risk of rape sclerotia is bigger than usual.
On February 14th, the Sichuan UAV custom farming team helped his customer’s 100 acres of rapeseed to apply boron fertilizer and rape sclerotia.

The shape of the operation plot is relatively regular, and the operation is carried out in the AB point mode. The flight speed is set to 6 meters to ensure operational efficiency. The routing width is 5 meters. This time the amount of mixture used is relatively large, so the higher Acre dosage of 9 liters was chosen.
Carbendazim is a broad-spectrum fungicide, which has the dual effects of protecting and curing various fungal diseases. It can be used for foliar spray, seed treatment, and soil treatment.
In this case, the main use of sclerotium disease that has not yet occurred is to play the protective effect of carbendazim. Brassinolide is a new type of green and environmentally friendly plant growth regulator, which can promote the growth of rapeseed, improve the quality, increase the yield, and make the crops brighter in color and thicker by spraying with appropriate concentrations of stems and leaves.
Since the DJI AG drone fully protects the crops from crushing, and at the same time the effect is very good, the grower has given a thumbs up to the drone’s control efficiency and operation effect.
Introduction to Pests and Diseases
Sclerotinia sclerotiorum is one of the important diseases in rape production. The incidence rate of perennial plants is as high as 10% to 30%. It can occur during the entire growth period, and it occurs most severely during the fruiting period. Stems, leaves, flowers, and siliques can all be affected, and the stems are the most affected. Light brown water-stained lesions appear on the stems after infection and then develop into long striped spots with a round pattern with brown edges. When the humidity is high, there will be cotton-like white hyphae on the surface. Black rat fecal sclerotia. The diseased leaves showed irregular water-soaking shape at the beginning, and then formed yellowish-brown central, dark blue peripheral, and light yellow peripheral spots. The siliques are infected with water-stained brown spots at the beginning, and then turn gray and white, and the seeds are thin and dull.
According to observations, rape sclerotia disease usually occurs twice, once in late November to December, and once in March to April of the following year (this period coincides with the susceptible flowering period of rapeseed, and it is also the victim of rape. The main period), if there is rainy, humid, and warm weather during this period, the rape sclerotinia disease will be serious.
Boron fertilizer can promote the growth and fruiting of rapeseed, and ensure the nutrient requirements of the plants during the flowering period. Severe boron deficiency can cause diseased rapeseed plants to shrink and die. When there is moderate to mild boron deficiency, rape cannot produce normal results. Foliar spraying of boron fertilizer can choose the late seedling period (before and after flower bud differentiation) and bolting period (stalk height 15-30 cm), and apply it two times. It is better to spray before 10 am or after 4 pm on a sunny day.
If you live in the Simcoe area, you will be very familiar with the black soil of 400 highway.
According to the history, this is the basis for the first layer of organic soil formed in the Dutch swamps 4000 years ago by decaying forest vegetation. Approximately 30 cm of dead material accumulates every year, resulting in extremely fertile black organic soil.
It is a great honor to be invited to do a flight demo for Holland Marsh growers! We are thankful to the association for the support of ag tech, the introduction of world cutting-edge precision DJI ag knowledge to members, and how these ag drones could benefit our wetland crops and ease the work for our growers.
The soils of the Holland Marsh are particularly well suited to the production of root crops, such as carrots, onions, beets, and parsnips.
DJI drones can work well on these wetlands and leave no prints in the fields. Since these equipment are not in contact with crops, it is avoid the touch and spread of weed seeds and the spread of pests and diseases as well.
Due to the DJI drone dosage, it can not only save 30-50% of pesticides but also protect the quality of the soil as the mixture will stay on the leaves as the mist droplets format, it will not drip down to the soil.
We demonstrated the two-in-one function of spraying and spreading DJI Agras T20 drones to growers.
Through the high-brightness touch screen remote control, the growers can directly plan the plots to be worked on through the GPS map. You only need to enter the amount of liquid required by each Acre in the remote control, and this fully automatic drone will set other parameters by itself, including flight height, flight width, and flight speed.
After the drone completes the operation, it will return to the take-off point.
A T20 drone is equipped with 4 batteries, 2 water tanks. You can replace the battery and the next tank within 10 seconds, and it can auto release air and do carlibration from remote control as well, just in few seconds.
The drone can automatically return to the breakpoint to continue the operation from the breaking point without missing any area or double spray any area, this is the merits of data based precision system.
We also shared with growers how the integrated ag drones system works without bothering about the matching and application of software and data between various ag devices.
Through the DJI P4M multi-spectral drone diagnose the change of the multi-spectral vegetation index, the undernourished area can be found in time, and then the DJI Agras drone of DJI can be used for variable operation for any target area or it can do the variable operation for the whole area. This is how you see the crop colour becoming more and more uniform. In this way, this technology can help the crops grow more evenly so that the bushel harvest in all areas is closer to the highest value.
Agricultural drones have changed our agricultural farming methods. It is not only convenient and enriching the agricultural life of each of us. Its cloud computing, big data function, artificial intelligence, edge computing technology, and agriculture are well integrated. This promotes the important driving force for the intelligent transformation of the industry in the production, operation, and management of various production links in agriculture.
We are very honored to be invited to participate in this panel of Trent University.
In the precision agriculture system, drones and drone systems have become an important aspect of agriculture, reducing inputs and increasing yields, while benefiting the environment and promoting economic development.
Agricultural drones are mainly a sustainable ecological clean technology device combined with earth science and natural resources, which greatly helps to analyze and improve crop production.
We are delighted to provide students with one tool in a useful toolbox so that when they graduate, they will be decision makers and managers in the industry. This is what they need to learn and know now, and need to practice.
Students learn that actionable and precise data can help farmers get more convenient, economical, and faster information in the right window to make the best decisions.
This is diversified thinking about agriculture in the digital age, and it is a collision of open and inclusive views on agricultural smart equipment.
From last year to this year, undoubtedly, the intelligent fully automatic DJI agricultural drone has become our hot topic. So what changes will DJI agricultural drones bring to our lives and agricultural production? What is the impact of the development of science and technology on women engaged in agriculture? Please take a look at the topics we shared.
Do not let gender limit your potential. Technology is a work that both men and women can participate in.
The gentleness and kindness women brought to the family, the support and confidence women instilled in the children, women are synonymous with land, and are synonymous with fairies.
Women’s participation in agriculture makes the mental health of agriculture more fair and tolerant.
Women, especially wise women, are the treasures of the family. Technology is an industry in which both men and women can participate, it breaks the barrier and promotes gender equality in agriculture, supports women’s participation in technology.
This agriculture tech provides a great platform to have so many young designs their own life and write their own story. They believed they could, so they did! You can do it too!
Sustainable agriculture education & Precision agriculture are tightly related as a career
I think everyone has heard one sentence, technology changes lives. Technology has been advancing, and we must continue to learn to adapt to the needs of the new era.
AI can help agriculture more effectively complete work in digital form，save and effectively use various resources, making agriculture and food supply more sustainable. There are now more and more green job opportunities in the precision agriculture field.
As an important part of smart agriculture, drones have enriched and optimized the structure of agricultural equipment and perfected the agricultural ecosystem. They are currently widely used by growers for some important aspects of farmland management.
* Spraying and seeding drones: commonly used for high-stem crops, densely planted crops, mature crops, wetland crops, etc.
* Multi-spectral drones: accurately and effectively convert data into the language of plants, which are commonly used in each growth stage of crops to help farmers intuitively understand the health of crops. Agronomists could use multi-spectral data to analyze crops’ health conditions. Precisely make optimal decisions about the actual crop diseases and insect pests and the nutrient requirements of the crops.
* Mapping drones: Surveying and mapping drones are mostly used in large areas of farmland. Through AI system analysis, it can quickly obtain high-definition farmland maps and identify farmland boundaries, trees, ponds, buildings, obstacles, etc., so as to help accurately plan the flight route of the required operation area.
Every farm has similarities and differences. We hope that the experience and knowledge of DJI precision agriculture drone equipment that we share can positively help bring out the best of your crop yield and boost up your agricultural business.
For a long time, due to lack of understanding, many of us have had some misunderstanding about agricultural drones:
1- I already have large-scale spraying equipment, do I still need agricultural drones?
For work areas that are not easy to reach by tractors and helicopters, drones can be good agricultural supplement equipment to fill the gaps in the very limited window period. So that to reduce the pressure from pest and disease and increase more yield from land.
For example, this kind of plot:
Can a tractor do it?
Answer: yes, but not easy…
Can helicopter do it?
Answer: not exactly…
What shall we do with this plot?
Answer: Drone for rescue!
Nobody like tracks, here’s the simple aerial solution. Imagine if your crop can increase the yield by 10-20%, maybe more, through such precise digital aerial management technology. Isn’t this a beautiful thing?
For irregular terrain, and slippery hillsides, small plots
Either big sprayer or helicopter would not like to do it…
Drone for rescue! Fast, efficient, and safe. It not only ensures the uniformity of the spreading and spraying work, but also saves the short window period of each of our Acre crops.
DJI AG Drones can not only spray foliar fertilizers, biological agents but also sow seeds and cover crops. We should let the equipment play its due advantage.
2- Application
AG drones can help you manage tall crops, wetlands, target disease areas in time, effectively increase benefits, reduce losses, and easily reach farmland areas that you could not reach before.
3- Is spraying other than pesticides subject to PMRA?
* Use drones for foliar fertilizer, biological, seeding, and spreading urea fertilizer is no problem.
* The time to clean the water tank and the material used to clean the water tank
* Time and labor cost for automatic exhaust and calibration
* Saved agricultural investment costs and time costs （ It saves 30-50% pesticides and 80-90% of water)
5- Improve work efficiency
* The drone can automatically navigate, and the left and right deviations of spraying and seeding paths are within 2.47 cm, reducing replay and missed area, and greatly improving work efficiency.
* During the limited crop window period, field management of high-stalk, mature crops, wetland crops such as sterilization, insecticide, weeding, etc.
6- Large area application
* Before you become an experienced drone pilot, we do not recommend that you operate a group of drones at once. You can’t rush for success. Equipment operation requires time for learning and training, and welcome to join our training class for skill operation training courses on DJI agricultural drone equipment.
* At present, drones can be used as a beneficial supplement to large-scale equipment, so as to effectively function where it can be used, thereby increasing output and increasing product quality.
7- Multispectral applications
The combined application of DJI multi-spectral drone technology saves a lot of uncertainty and guesswork about crop health.
Using DJI P4M for crop health diagnosis, and then using DJI Agras drone for variable operation, do you see the colour change from inconsistent to gradually uniform? This means that the crop is growing evenly, and it also means that the yield of each acre can reach the rightmost harvest value you usually see.
For a farm, every bu/acre matters. In the middle and late stages, drones are used for stand corn operations to manage diseases, insect pests and nutrientriants, which can increase an average of 12-21bu/acre. Isn’t it beautiful?
Moreover, the DJI Agras drone can save 30-50% of the dose and 80-90% of the water. Through multi-spectrum, instead of blanket carpet applications, growers can save 20-30% again of pesticides and 10% of fertilizers, and increase production by 10%.
On average, farmland application and management through DJI drone agricultural equipment can save an average of 70% of agricultural management costs.
This picture shows that after precision farmland management is carried out by drones ( Agras drones + P4M), the growth of crops gradually tends to be even, so as to achieve a better effect of increasing crop yields.
The purchase and application of these precision DJI AG drone technology may be the most economically significant investment in your agricultural business.
8- Career planning of drone custom farming
The application of drone technology in agriculture may be the industry with the least input and the highest output.
Calculated based on the work area of a 19-year-old girl in Mexico using a drone for a year of 12,300 Acre. In 2 years, you can afford the down payment for a house.
There are also these career plans to choose from, and large farms can also hire agricultural talents with professional high-tech equipment in these areas:
This year’s climate change is not normal. Some areas are too hot and dry in summer, and some places have too much rain.
The problems
We received calls from canola growers. They mentioned that the growth and maturity of canola crops vary throughout the field this year, there are many weeds in the field irregularly distributed in the rape field. A large spreader will reduce the crop yield, they don’t want to do that, they need to desiccation the field, target the weeds areas by using the aerial application.
Desiccant
These symptoms have been caused by heat and drought stress throughout the growing season and desiccants are used to improve crop uniformity so that the crop dries out more quickly and evenly, desiccation will even crop maturity to allow for a timely and even harvest with optimum quality and this helps to desiccate weeds and plants and increase harvest efficiency.
Drone Solution
Growers are currently spraying desiccants on sunflowers in many countries around the world by using DJI AG drones. The crops are protected, and farmers have increased their yield, which is very popular with growers.
We combined with the application cases of drone spraying desiccant all over the world. The agronomist carefully matched the ratio of drone spraying. We and growers tried drone spraying desiccant in a small area and carried out targeting spray.
In order to increase the coverage rate of the herbicide activated by sunlight the next morning, so that the plant tissue can absorb it more completely. We use the drone’s AI fully autonomous RTK operation function at night, and spraying desiccant at night will slightly spread the herbicide from the droplet contact point.
The effect is exciting.
Grower’s review:
The herbicide appears to be working very well. The crop appears to be uniformly dying with good penetration into the bottom. Looks good!
Canada has four distinct seasons, fertile soil, abundant rain, and sufficient sunlight. Canadian soybeans grow on the world’s largest freshwater system and fertile land. They are world-renowned for their excellent quality.
Our tireless farmers have been actively using precision agriculture technology to continuously improve their farms to grow these leading quality soybeans.
Weeds problem in maturity soys
Soybeans are about to mature in mid-to-late September, but there are a lot of weeds in the observation field at the beginning of the month. If you use a tractor, it will cause a lot of yield and economic losses. Moreover, the areas where weeds grow are irregular, some are many, some There are few places, and some weeds gather in the middle part of the soybean field, which brings a lot of inconvenience to the harvest.
Some soybean growers contacted us, hoping to use drones to test spraying weeds in soybean fields.
Solutions:
The agronomist carefully prepared the mixture according to the recommendations of the drone dosage, we used the T20 drone to conduct a small area test. Due to the irregular area, we planned the drone flight route for the target area and then carried out the fully autonomous target spraying operations according to the planned area.
Customer’s review:
The work of the drone is impressive. I am very surprised that the spraying measures out the liquid can be set up very precisely from remote. It protects soybeans and prevents the spread of weed seeds with the tractor.
DJI agricultural drones are modern agricultural equipment based on artificial intelligence technology and accurate digital computing power.
You only need to simply enter the sowing parameters you need, set the opening size of the spreading tank, use seeds between 0.5mm-5mm, and its rate is very accurate. For sowing small seeds, clover seeds, alfalfa radish, mixing with large-seed grass or rye, granular urea is no problem.
Sowing red clover into winter wheat is not only beneficial to soil health and structure but also increases the yield of other crops in the rotation. The seeds will germinate well at lower temperatures, which makes it ideal for planting clover into winter wheat in early spring.
The general method of spreading clover is to use an ATV with a rotating spreader to avoid compaction. Generally, growers sow red clover at a weight of 8 to 10 lbs/acre.
After the spring snow melted, the land was very wet and soft, and large machinery could not enter it.
In March of this year, we used the DJI T20 2-in-1 spraying/spreading drone to spread clover in the air in winter wheat.
Customer’s review: In this video, the DJI AGRAS T20 UAS (drone) launches loaded with Red clover seed returns to where it left after returning to reload with seed and fresh battery to make a few 15 foot wide passes back forth to finish off a 4-acre field of #pioneerseeds #25R74 winter wheat on March 27th, 2021.
The field boundaries had been entered on the controller using the satellite imagery on the touch screen. The downdraft from the UAS is quite impressive and undoubtedly negated any impact of the light breeze of 5 knots..
The seed distribution appeared to be good. The field was too wet to be passable by ground rig as we had 2″ of rain two nights before the flight.
Growers usually spread cover crops at the 50% yellow leaf stage when soybeans are about to mature to benefit the seedlings of the cover.
DJI agriculture drone’s aerial sowing mulch is a very crop-friendly application, it is not only spreading uniformly, also that it does not leave prints, but more importantly, as it does not touch corps, so that it does not bring some diseases or weed seeds to various places in the field, which greatly improves the uniformity of soil fertility, protects the crops and unlock more crop yield potential.
How does it work?
The amount of spread required for each acre can be set directly from the remote control, including the spreading width and flying height. After the parameters are set, the drone will accurately perform operations according to the requirements and RTK routes you set.
After the operation is completed, it will automatically return to the take-off point.
All you need to do is replace the battery and refill the tank. One unit is equipped with 4 batteries so that you can work continuously.
The spreading tank of the Agras T20 is 20 kg. According to the application of 10lbs/acre and its work efficiency, it can operate 30 acres per hour.
The Red Clover is coming nicely see how it overwinters – this was applied Sept 1 into standing soys.
Red Clover progress report first 2 pics were from the drone flown into standing beans. Last 2 photos where established when we drilled the wheat. Approx 1 month between “plantings” rest of the field will be frost seeded next year.
Agriculture is a great industry, which ensures that everyone has enough quality food to eat. Farmers are at the forefront of the industry. They should be able to have enough support and should be respected. We need to create equal technological conditions for everyone in it.
Big thank you to Outdoor Farm Show for bringing our local growers the most advanced and popular for-front tech to the show, the DJI’s full range of agricultural drones. This opened a new chapter in our Canadian precision technology agriculture.
We shared the whole series of drones with participants which including mapping/surveying drones, multispectral crop health analysis drones, and seeding and spraying two-in-one drones.
The measuring drone Phantom 4RTK can accurately map the spraying route of all the areas that need to be operated in a short time so that the grower can quickly and intelligently understand the farmland, so as to ensure the best application based on the health of the crop.
The Multispectral drone P4M, the same as Phantom 4 RTK, can cover an area of 167 Acres within half an hour. These accurate, high-definition multi-spectral real-time data are not affected by clouds, it is more timely and accurate than satellite data.
You can scout crops’ health with it at any time. The data can be quickly analyzed by DJI agricultural software Terra. It is very convenient to identify if the crops or soil are under pressure and the agronomist could give variable application plans according to these data.
We can see that one week after variable fertilization, the growth situation has been greatly improved.
We in Canada have an excellent team of agronomists.
The design of DJI agricultural drones and precision agriculture aerial applications undoubtedly provide them with the best method.
This system will spray and fertilize all agriculture, analyze crop health in real-time, and lock the crop problem area target in the air.
The problem area treatment is easily converted into a breeze for our growers. These devices not only greatly reduce the cost, but also indicate that the yield can be increased through controllable, precise artificial intelligence and digital scientific methods, and the income of growers can be greatly increased.
During the two days demonstrated in Canada’s Outdoor Farm Show, winds reached 18-26 km/h. Drifting under the action of the wind is inevitable, however, DJI has the world’s most advanced wind laboratory and the most rigorous drone engineering design center. The growers said that they saw the unbelievable balance of DJI Agras T20, and the powerful down-pressure wind field greatly reduced the drift, the droplets were accurately and uniformly sprayed on the soybean till to the roots.
Every small achievement actually has undergone thousands of laboratory and field tests. The final result is that the effective spraying width of T20 is 7M.
Because the remote controller can set the spraying width to 4M-7M, the drone will not miss or repeatedly spray any area.
The drone demonstrated this year is DJI Agras T20.
The models to be launched next year are T30 and T10. Pre-orders are now accepted.
These drones only need 10% of the current mixture to complete the same operation effect, while saving 50%-30% of pesticides.
The advantage of T20 and T10 is that their spray tank is pluggable, and it is convenient for growers to prepare two liquids at once without cleaning the tank.
At the same time, the T10 take-off weight is less than 25 kg, and the basic UAV pilot certificate can fly it.
The T20’s advantage is it comes with 2 tanks. You can have another tank ready before the drone land off.
The capacity of T30 is a 30L spray tank, which cannot be plugged in, but it can achieve more effective spraying, especially for fruit trees. This is a major advancement in global aerial spraying.
This is also the first and only drone in the world that can be sprayed according to the growth direction of branches by the outstanding DJI R&D staff.
The drone T30 helps reduce fertilizer use and increase production through effective, data-driven best practices. Its unique branch aiming technology and adjustable arm enable Agras T30 to penetrate thick canopy through oblique spraying, ensuring uniform spraying of liquid pesticides and doubling the number of droplets.
These drones can all work in groups. A pilot can use one remote control to remotely control 3 drones at the same time, which greatly improves the operational efficiency of agricultural operations.
This technology is a miracle of agriculture. At present, DJI’s agricultural drones have been widely used by farmers all over the world. Through searching the Internet, we have coincidentally seen articles shared by everyone saying that DJI’s drones are spraying accuracy and the results in respects of optimal use of chemicals and liquid fertilizers exceeded expectations, thereby reducing costs and ensuring that the specific needs of each crop are met.
DJI agricultural drones have made outstanding contributions to sustainable development.
It uses high-performance batteries instead of fuel, which greatly reduces carbon emissions. The battery does not need to be cooled and can be charged directly (if you use a generator to charge the battery, you can save 60%-70% of fuel).
It is small and flexible, can be folded, is equipped with high-brightness LED lights, has RTK function, and the saved map can be found and used from the remote control at any time. Growers no longer have to worry about a series of problems such as work at night, wetland, and short window periods for crops.
The application of agricultural spraying drones means that less water is used, and accurate pesticide usage calculations ensure that it can reach where it needs to be accurately and uniformly. Instead of wasting or flowing into the fields.
It is our great privilege to be the general distributor of DJI agricultural drones in Canada. We are very willing to work hard with Dealers in provinces and regions to comprehensively train and help local agronomists and growers through the use of these efficient and advanced agricultural aerial tools to improve work efficiency, enhance the safety of agricultural tools applications, and protect their health from the spraying environment.
Thanks to the brilliant DJI R&D staff, they bring out all the best of this high-tech equipment and make them easily used by growers.
Through accurate computer analysis and precise data calculation, this kind of drone sprays can help to achieve more effectively, more cost-effectively, less harmful to humans, and friendly to the crops and environment.
The development of science and technology has been advancing, and the development and application of science and technology by brilliant R&D friends are gradually making our lives more convenient.
The development of agricultural science and technology is gradually moving towards intelligence, precision, and efficiency. Meanwhile, the modernization of agriculture has increased the income of farmers and promoted the continuous optimization of the agricultural economic structure; thereby improving and protecting the ecological environment and promoting the sustainable development of agriculture.
So, how can drones be a beneficial addition to agricultural tools
1- No Compaction
Some fields are relatively wet after rain/snowmelt. At the same time, there are often places, irregular fields, rolling fields that hard to deal with. The sprayer drone is a just-right tool to help with these concerns.
2- Easy to carry
DJI’s agricultural drones can be folded down to 70-80% in size. The sturdy frame construction makes it easy to load on a truck for transport.
3- Low volume and high deposition tech
The production, research, and development of agricultural drones in DJI have always been very rigorous. There are not only countless tests of every function in the laboratory, but also thousands of field tests to ensure that the products are qualified and safe when they are released to the market so that farmers can use the products with confidence.
DJI sprayer drone technology can help you save 30-50% chemicals, use only 10% around the mixture to achieve the same yield compared with a ground rig. This tech has been proved by so many countries and regions, including Bayer US. They tested corn and soybean field in the season of 2021, we can see in the chart below that DJI UAV was using only 10% around the mixture to achieve the same yield.
DJI spraying drones either T20 or T30 are equipped with solenoid valves and flowmeter systems to ensure that the amount of liquid from each pipe and each nozzle is uniform.
At the same time, the wind field of DJI UAV is not simply a wind field with propeller pressure as we think. This is calculated through scientific calculations and tested thousands of times from wind field labs and farm fields. The designed downward pressure wind field makes the leaves of fruit trees evenly sprayed on the front and back（This solves the problem of bugs hiding behind the leaves.）. You are welcome to check some fruit tree spraying articles that were shared in our Case Study.
2- Saving
Only use 10% of the mixture, use 30-50% of the medicament. Save 60-70% fuel. This is an amazing saving. You can calculate how much money you can save in a season. No doubt, these savings become your profit and keep you in a leading position in the fierce market competition.
3- Spraying width
The T20 can be set to 4M-7M on the remote control, T30 is from 4M-9M, you will not miss any corners. Traditional equipment needs to turn off some nozzles, but turning in corners is sometimes a headache. The drone can directly adjust the width of the spray, thus avoiding repeated spraying or some places being missed. If the corners are not sprayed, that is where the pests and diseases started, and the diseases spread from the edges to the inside of the farmland.
4- RTK positioning
The spraying route accuracy can reach 2.47 cm.
This error size of less than one inch ensures that the drone sprays strictly according to the route you require, and when you spray, it minimizes the impact on neighbours’ farmland.
5- Hillsides and wetlands
It is not restricted by terrain and land moisture. In many areas, DJI’s Agras drones are used for rice sowing, spraying, and fish feed sowing, so it is not an exaggeration to say that it is an aerial robot above the water.
6- Tall crops
With fixed-height radar, it is not restricted by the height of crops, thus well protecting the crops. The drone’s fixed altitude radar can accurately calculate the distance from the bottom of the drone to the tip of the crop by itself, to imitate ground flight.
7- Personnel safety
The operator always uses the remote control to operate, thus avoiding being in a spray environment for a long time.
8- Calibration
Each nozzle of T20 or T30 does not require manual exhaust calibration, which can be completed in a few seconds by a one-key operation of the remote control. This greatly saves the operator’s time and energy.
9- Signals
All the DJI Agras drones are equipped with an RTK2 mobile station that works independently to receive satellite signals. It ensures that your spray/seed drone equipment works smoothly, so your operation will not be affected by your cell network.
10- Application range
Its application range can not only spray farmland but also spray fruit trees. You no longer need to replace equipment for spraying in orchards. In particular, T30’s unique branch orientation targeting technology is the world’s leading cutting-edge technology.
11- Protect the soil
Obviously, it protects the soil from compaction. Moreover, the sprayed droplet size strictly meets the best standards of our Canadian pesticide management regulations. Water droplets will not fall into the soil from leaves, thus protecting the soil.
12- Spreader Drone
It can also spread, but sowing is not the main function. But for plots with fewer lbs seeds requirements, it is completely capable. 1 unit of T30 can do 1 ton of urea fertilizer in one hour.
If your driveway or farm walk is long, you can also use DJI’s RTK Agras drone to spread ice salt. It can be used above minus 10 degrees.
The map can be saved to your remote, you can pull it out to use at any time you need.
This year we received more calls and emails than ever before.
Actually, many countries tested drones on pesticides for already many years and actively to utilize the precise drone tech with our current tools, we can tell that everybody was excited about the results. Regarding the case of drones spraying pesticides on different crops, you are welcome to search the Internet for information. We have also compiled some cases of drone spraying pesticides for your reference. The link is at the end of the article.
Indeed, it can be used for vicious poisonous weeds before arable land no longer requires whole-field spraying, and drones can achieve spot spray. It also helps to work on the edge of the plot to reduce the spread of pests and diseases to the interior. However, the label isn’t coming out yet… Is drone an option for our Canadian growers?
What we have learned, an application for a label requires a lot of testing and research work, not something that can be done in a few years. Other countries, their local growers actively work with agronomists, ag experts, professors, and chemical companies, dedicated to testing and trying things out. After all, as clean and sustainable tech, this method can save 30-50% of pesticides and 80-90% of water.
I remember once a grower said:
The central part of the United States has begun to apply it on a large scale. The EU Plans To Reduce Pesticides By 50%. It wouldn’t be fair to our nation’s growers if everyone’s costs were reduced.
Now, along with the app of the drone in real agriculture production, the key point of everyone using drones is not to save pesticides. They are mainly used after rain, on tall crops, spot spray weeds, hillside crops, and mature crops desiccant spraying. As a complementary tool for larger equipment.
For crop dusters, aerial applicators, custom farming, it’s very clear that the drone tech isn’t a competition to you, reverse, your previous mission impossible can now be converted into profit. This would be your new business profit angels.
With the development of science and technology, the level of agricultural mechanization has been continuously improved. As a powerful helper for large-scale machinery, DJI agricultural drones have been widely used in the field of global crop protection.
This year, we talked to growers about some of the toughest crop applications at the moment, using DJI’s spray 2-in-1 drone, the Agras T20, for some demonstrations and tests in different parts of Ontario. Very pumped to see we have many experts and professors to lead the way in trying the new technology with growers. Hope more researcher and experts could participate in and try this new tech to see if it is indeed can bring values to our ag industry.
Regarding the application of pesticide drone spraying, we would like to clarify here. For a long time, everyone has had such a misunderstanding that it is a drone company that needs to contact PMRA to apply for a pesticide label. In fact, PMRA has been waiting for chemical companies to apply for a label that can be used by drones.
We only have agricultural drones and technology, that provide growers convenient, safe, and easy access and practical devices and we would be very glad to share with you this tech so that you can have this additional tool to empower the ag field with your current tools.
However, the drone is not a tool that can only spray pesticides… It’s entirely up to you whether you’re willing to research and use it for pesticides. You are our industry leaders who determine the direction and speed of progress. We just have an advanced tool.
To our Canadian growers, the good news is, The DJI Agras T30 now can be registered with Transport Canada, and the drone is currently widely used for sowing clover seeds precisely & accurately, cover crops, pollination, urea fertilizer, and foliar fertilizers. These are all legal.
Agricultural production is not easy. If one step is not done well, a year will pass. We all face challenges, not just pests and diseases but also natural disasters and material prices.
We have selected several cases about the application of drones in Canada to share with you. Hope these cases can give you some inspiration to see if this tool can help you overcome some obstacles in agricultural production, meanwhile，you can judge whether drone technology can help your production applications in some aspects.
For some completed articles, clicking on the text will have a link. If there is no link, the article is still in preparation. stay tuned. Also, you are welcome to give us a call or email to find the information you need. We are with you!
With the widespread use of plant protection drones around the world, the “trend” profession of plant protection pilots has also entered the field of vision of the Ukrainian public. As of this year, the number of plant protection drones in the Ukrainian market has increased by 8 times compared with last year . “Plant protection pilots” have also begun to become a new career choice. Pavlo Laskovets from Ukraine transformed from an IT engineer to a DJI plant protection drone pilot. His entrepreneurial road.
Pavlo’s first “connection” with DJI Agriculture
Pavlo is an engineer who previously worked in sales and consulting in the IT industry. Later, by chance, he saw an advertisement about pilot training on the Internet. “Suddenly stimulated my great interest. At present, agricultural technology is in a period of rapid development. My intuition tells me that the application and innovation of drones in the agricultural field will fundamentally change the future of the industry in the future. I am serious. After thinking about it for 2 days, I dialed this call. After a period of learning and precipitation, I successfully transformed into a plant protection drone pilot.” Pavlo recalled.
Pavlo Laskovets’ first job
As an IT engineer, Pavlo talked about the first time he went to the field to spray medicine for a client. “The first task I received was to spray desiccant on sunflowers and corn. At that time, I was both excited and nervous. I spent a lot of time consulting senior colleagues on many details, and prepared as much as possible for unexpected situations, and finally successfully completed my first job. In the past, most of my customers used fixed-wing agricultural aircraft, but This will cause a certain amount of damage to crops, with a loss of 3% to 7% of the harvest. If calculated in a thousand hectares, the economic income loss caused by this cannot be underestimated.”
Don’t be afraid of “clearly settle accounts”, cost saving is visible
At the beginning, Pavlo’s customers had concerns about plant protection drones to fight drugs, but his strategy was to “clearly settle accounts” with customers. Pavlo, who is an engineer, is naturally sensitive to numbers, and his past experience in sales and consulting has just become a bonus for his new career.
“In the long run, if you use a plant protection drone, the water required per hectare (1 hectare = 2.47 acres) . If you use traditional sprayers to operate, 100 hectares will require 15-20 tons of water. Use DJI T20 Drone spraying requires only 6 tons of water for 100 hectares. If the farmland area is 10,000 hectares, 2,000 cubic meters of water can be saved, which is equivalent to the water consumption of the entire Olympic standard swimming pool. This saving is considerable, and even saves More and saves resources.” Pavlo said confidently.
Zero industry experience, new career prospects
Pavlo didn’t have any industry-related experience in agriculture in the past. He gave up a high-paying job in the IT industry and decided to start a business. In addition to being optimistic about the plant protection drone track, he also believed that he was doing a “valuable job”. “‘S career. “In terms of physical strength, only two people are required for the job, a pilot and a deputy. The job price per hectare is 350 hryvnia or higher. Therefore, only 20 days are required that I will be able to recover the cost of purchasing the machine and start to make a profit. The investment is small and the return on the cost is fast. The most important thing is that I think the business I have done is very valuable. We are trying to use technology to innovate the traditional way of working.”
Ukrainian farmers usually have a farm area of 50-80 hectares, small customers do not have the ability to purchase fixed-wing agricultural aircraft, medium-sized customers have difficulty in hiring pilots, and large agribusinesses lack manpower during peak seasons. Pavlo aimed at the market gap of plant protection drones and quickly seized the market.
“The advantage of plant protection drones is that in places where tractors are impassable, drones can pass unimpeded. In addition, large aircraft can operate at a price of up to 500 hryvnia per hectare, which does not include construction. For some small customers, the cost of spraying pesticides and pilots is prohibitive.”
“Another key point is that in the past few years, one-fifth of the pilots around me have switched from aviation spray aircraft. This is the market demand and the industry’s potential.” Pavlo added.
Jump out of your comfort zone and achieve your new self
Has Pavlo regretted giving up a high-paying job in the past and choosing to start from scratch? Pavlo smiled and replied: “I never regret it. Only after leaving my comfort zone can I have a chance to enter the wider world. I am now not only a pilot, but also the leader of the company.
In the process of starting a business, I kept upgrading and fighting monsters and exploring new areas. In the past, there were many pain points in agriculture. Plant protection drones have brought solutions to this industry. We cannot stand still, or we may miss the industry market. I hope that more young people can join the plant protection drone industry and make their own way.. “
The high-quality beef we usually eat comes from the good pastures of the cattle farm and the careful management from the young cattle period. Therefore, we can obtain high-quality meat, milk, and cheese products.
Problem
We received a call. This is a farm on a bumpy hillside with very irregular terrain. It is not easy to reach the corner areas of normal operations, and they usually have to give up.
Traditional operations
Growers usually use a ground sprayer to do where ever it can reach. There are also areas where the nozzles are turned off and the arms of the equipment are folded to achieve operation, but the slopes are very slippery and sometimes very dangerous.
Pests and diseases often spread from surrounding areas to farmland. The treatment of borders and corners is very important to protect crops and increase yields.
Solution
DJI AGRAS T20 is equipped with omnidirectional radar plus the fixed-altitude radar （No one can catch up with this technology so far), which can protect the drone in a safe work environment while simulating ground flight according to the undulation of terrain and the height of crops.
We used DJI Agras T20, which is a two-in-one drone for autonomous spreading and broadcasting. First, we planned the plots to be worked on on the remote control, and then it started to work fully automatically and autonomously.
The small red dot on the yellow line is the running drone, and the green dot is the end of its work.
No more pressure
Spreading/spraying operations or services are no longer under pressure. Drones can reach places that large equipment cannot reach, and are not restricted by terrain and soil moisture. If you already have large-scale equipment, drones can complement your equipment well and fully help you complete the work of the farm.
Narrow space
T20 can set the spraying width from 4m to 7m, and will not overspread, leak spray or drip. There is no more pressure on uneven land, wetlands, high yields, some damage and soil compaction.

Rural life, beautiful scenery. The hard work of farmers and the risks they bear to agriculture are far greater than the definition of a farm.
DJI precision agriculture technology is a key tool to help farmers manage agriculture easily, accurately apply pesticides, and apply scientifically. As a result, agricultural investment is greatly reduced, the output is increased, and work efficiency is improved. The savings are amazing, and the effect is very significant.
Due to the continuous rainy weather, the fields are very wet and soft. When the corn grows high and urgently needs fertilizer, it is difficult for traditional machinery and people to get in. At the same time, the operation of traditional ground machinery will overwhelm the crops and cause the yield to fall. The application of drones effectively avoids damage to corn and increases yield.

In early 2021, South Africa’s second drone flight permit was once again granted to DJI Agriculture. Today, DJI Agriculture is the only brand allowed by the South African government for plant protection operations. Its plant protection drones not only serve South Africa’s sugarcane, forest trees, corn and other crops, but the local team also increases employment opportunities and creates greater value through pilot training programs and community programs.
PACSys team trained for the people of Tanzania
From zero to one, breaking the deadlock
In 2016, DJI Agriculture entered the African market.
At that time, the South African government was completely opposed to the “plant protection unmanned aircraft”. It neither provided a path for legally compliant operations, nor did it have any agent suitable for drone spraying. The task of entering the game to break the ice is slowly underway.
Tim in a speech
Within three years, Tim , the head of the PACS y s team, led the team throughout South Africa to test on different crops to verify the effectiveness of flight defense. Experiments have shown that, whether it is corn, wheat, sugarcane, citrus, etc., DJI plant protection drones are effective. In terms of product reliability, multiple safety tests such as collisions and drops have also gradually eased the attitude of the South African government towards plant protection drones, and finally fully accepted it.
During the experiment, Tim also found that the fundamental need of local farmers is to improve the quality of their crops. Compared with large airplanes, small drones can achieve precise spraying, saving water and reducing medicines, which perfectly fits the concepts of green planting, medicine reduction and efficiency enhancement required by the South African government.
At present, the DJI Agriculture and Tim team, together with BASF, Syngenta and other pharmaceutical companies, continue to carry out experimental cooperation on different crops, and provide better solutions to improve farm efficiency and crop quality.
Benefits increased by 25%
Let the land maximize its value
South Africa is the world’s largest sugar producer, with 380,000 hectares of sugarcane planted, making it the third largest crop in South Africa. Limited by terrain and other factors, traditional sugarcane orchards mostly use large planes for plant protection operations.
Due to concerns about the drift of the chemical liquid affecting the growth of other crops, large aircraft generally only spray the middle area of the sugarcane field. As you can see in the comparison chart below, a large area around the sugarcane field is left blank (green band).
(The yellow area in the picture represents sprayed, green represents not sprayed)
In contrast, drone operations can achieve 100% coverage, effectively play the value of every inch of land, and bring 25% additional income to sugarcane farmers . Faced with pressures such as water shortages and insect pests, drone spraying can effectively ensure product quality and enhance sugarcane farmers’ bargaining power .
Tim said that the 25% increase in efficiency is only a conservative estimate.
Restricted by factors such as land, manpower, and management level, South Africa’s sugarcane orchards are mainly operated by large farmers, and there are still a large number of small sugarcane fields that have not been developed. The popularization of plant protection drone technology can not only effectively develop sugarcane fields that have not been cultivated , but also create new jobs in nearby communities and achieve greater social value .
Sugarcane plantation in operation
Cooperate with Agricultural Education and Training Bureau
Promote the development of modern agriculture
In addition to services and crops, the plant protection drone pilot project led by Tim has been in operation for nearly 4 years. In 2021, the South African plant protection drone training program passed the certification of the Agricultural Education and Training Agency (AgriSeta), and will focus more on serving agricultural practitioners in the future.
Pilot training
Currently, the pilot project is still in the stage of vigorous development. By granting scarce skills in the agricultural field and enhancing the professional level of the “new farmers”, DJI Agriculture and its partners send more highly-trained agricultural aviation experts to South Africa.
