Corn is the top-produced crop in the U.S., accounting for a significant portion of the country’s agricultural output. However, corn farming is fraught with challenges such as pest infestations and fungal diseases that can severely reduce yield.
Fungicides are an essential part of corn farming, protecting plants from fungal diseases that can cause significant damage. These diseases, such as Gray Leaf Spot and Northern Corn Leaf Blight, can greatly reduce yield if left untreated. Traditionally, fungicide spraying has been done by ground-based equipment or crewed aircraft, both of which have limitations in terms of efficiency, cost, and accuracy. This is where drones come into play.

Traditional Farming Techniques vs. Drone Technology

Before the introduction of drones, farmers relied on methods like tractor-mounted sprayers and crop dusters to apply pesticides and fungicides. These techniques, while effective to some extent, come with their own set of limitations, including high costs, soil compaction, and inefficiency in complex terrains. In contrast, drones offer a more precise and targeted approach to crop spraying, reducing costs and minimizing the impact on the environment. Compared to traditional tractor technology, drones are more economical due to their high cost-effectiveness and low maintenance requirements. With user-friendly controls, they are easier to operate and manage. Unlike tractors, drones can perform operations immediately after rain, preventing delays. They also avoid crop-crushing and soil compaction, preserving the field’s integrity. Furthermore, drones are well-suited for rolling hills and small to medium-sized plots where tractors may struggle.

On a typical workday, the Lancasters utilize the DJI SmartFarm app to devise flight paths, ensuring maximum coverage and efficiency. Once the drone’s spray tanks are filled with a liquid fungicide mixture, the drones take off, following their predetermined routes and spraying fungicide according to set parameters. After completing the spraying, the drones return to the landing platform, where operators replace the batteries and refill the spray tanks for the next round.

A Command Center to Match

The Lancaster brothers deploy their T40s from the landing pads of a custom-built command center designed to facilitate efficient agriculture drone operations. Transporting two T40s to and from the field is greatly simplified thanks to this vehicle. After arriving at the field, the truck transforms with retractable platforms, offering ample space for two drones to takeoff and land.

Working from an elevated platform has many advantages. During takeoffs and landings, the separation from the ground helps minimize dust kick-up. During operations, the higher vantage point helps the Lancasters maintain visual line of sight, while maintaining an uninterrupted line for transmission between the remote controllers and the drones.

While waiting for the drones to spray a load, the brothers stay cool in the hot August weather thanks to two fans and a red umbrella that matches the truck’s cabin.

Understanding Rice Growth Periods

Generally, there are some periods for rice growth and here is the main focus on each period of rice growth:

Vegetative (tillering)
Reproductive (flowering)
Ripening

To achieve optimal results in rice spreading and fertilization, it is important to understand the different growth periods of rice plants. This knowledge can help determine the appropriate timing for seeding and fertilization using agricultural drones.

1. Selecting the Right Spreading Time

Rice growth is significantly affected by seasonal and climatic conditions. Selecting the optimal planting time is crucial for successful cultivation. The ideal sowing period for rice seeds differs by region, so it is important to refer to local climate data or consult agricultural experts and agronomists when planning the planting schedule.

2. Pest and Disease Control

Rice crops are susceptible to numerous pests and diseases that can greatly affect both yield and quality. Conducting regular field inspections is crucial, and prompt control measures should be enacted upon detecting any infestations or infections. This proactive approach helps minimize losses and ensures the health of the crop.

3. Timely Fertilization

Proper nutrition is crucial throughout the various stages of rice growth. Apply nitrogen, phosphorus, and potassium fertilizers as required, taking care to avoid over-fertilization, which can result in soil pollution and environmental harm.

4. Efficient Field Management

Rice fields require effective management practices, including weeding, pruning, and supplementary fertilization. These activities help promote healthy growth, increase yield, and improve crop quality.

Preparation Before Drone Spreading and Fertilization

1. Ensure Flight Safety

Before starting any drone operation, ensure that the flight environment is safe. Drones should avoid any collisions with people, buildings, or other obstacles during flight.

2. Accurate Positioning and Flight Route Planning

Effective route planning is essential when using agricultural drones for spreading or fertilization. Proper route coverage ensures that every section of the field is seeded or treated, reducing the risk of gaps or overlapping coverage.

3. Appropriate Flight Parameters

Adjust the drone’s flight parameters such as altitude and speed based on crop height and field conditions. Lower altitudes generally improve spraying or spreading accuracy, but care should be taken to avoid colliding with crops or uneven terrain.

Here are parameters recommended for spreading rice seed:

Height Above Crop	4 - 5 m	Application Rate	140-200 kg/ha
Flight Speed	6 – 7 m/s	Route Spacing	4.5 - 5.5 m
Mode	(Auto)Route Mode	SpinnerSpeed	900-1100 rpm/min
Scenario	Route Mode + Above water (if have water surface)	Hopper Gate	Standard
Obstacle Avoidance	Turn on	Wind Speed	Below５m/s
Low Speed Ascend	Turn on	Flight Optimization	Auto Route Spacing Adjustment –Turn on Smart Resume – Turn on

Regular Maintenance and Inspection

Drones and its spreading systems require regular maintenance to ensure operational efficiency and safety. Regular inspections of the spreading system, flight control systems, and batteries are essential to maintain accuracy and reliability.

Spreader Cleaning: After each use, remove and clean the spreader. A steam cleaner can be used to remove any stuck fertilizer or manure from the motor module and control board. Follow this by wiping it clean with a damp cloth and then drying it with a dry cloth.
Plastic Bin and Spreader Plate: Clean these components using a water hose and brush to remove any remaining material. Allow them to dry completely before storage.

Video for spreading system maintenance:

Considerations with Agricultural Drones

Route Spacing Settings During Spreading: There’s a fundamental principle: As a drone’s flight altitude rises or its spreading disk speed increases, the row spacing may expand. Therefore, it’s crucial to adjust route spacing appropriately to ensure even seed distribution. To prevent rice seeding overlap between routes, it is highly recommended to adhere to the aforementioned parameters.
Calibration for New Materials: When switching to a new material, such as a different seed type or fertilizer, create a new calibration template to ensure accurate application rate. Calibration should include loading the new material into the spreader and adjusting flow rates.

Video for creating a material template:

Flat Terrain Requirements: Fields for rice spreading should be level, with variations in height not exceeding 5 cm. Uneven fields may result in water pooling, hindering seed germination and emergence. It’s recommended to use a tractor to level the field first and check if it’s even or not.
Seed Pre-Germination: Pre-germinated rice seeds should have sprouts between 1-3 mm. Sprouts longer than 3 mm may cause blockages during spreading, leading to uneven distribution.

Low application rate: If you plan to apply a very low rate, between 5-25 kg/ha, consider switching from the standard hopper gate to a small one.

Note: T50 & T25 have large (standard) and small (optional) hopper gates that can be swapped. T40 &T20P have large (standard), small (optional), and smallest (optional) that can be swapped.

Here is a video guide for installing the small hopper gate:

Common Errors and Troubleshooting

Incorrect Flight Altitude: If the altitude is not suitable, especially in water-covered fields, use the “above water” setting for better control over operations.

Wide Row Spacing: The route spacing should not exceed 6 meters when spreading rice seeds due to their higher friction. Wider spacing may cause gaps, leading to uneven distribution.
Spreading Omission: If spreading errors occur due to internal shrinkage settings or a lag in shutter timing, check the germination status after 1-2 weeks and manually address any gaps. Updating to the latest firmware may also help prevent such issues.
Drone U-turns: When the drone goes beyond the field during U-turns, set a safety distance for better control at field edges.
Uneven Route Spacing: If the spacing on the left and right sides of the drone’s route is inconsistent, set the route interval auto-adjustment to ON and update the route settings for balanced coverage.

Precautions for Fertilizer Spreading

Battery and Fertilizer Loading Order: When loading fertilizer, ensure the battery is inserted first. Dust that kicks up when pouring fertilizer can cause rusting of the metal battery connector, especially on the electrified distribution board.

Fertilizer Flight Parameters: The use of fertilizers is less strict than that of seed spreading, and the range of settings could be wider.

Here are recommended parameters for spreading fertilizer:

Height Above Crop	3 - 4 m	Application Rate	50 – 750 kg/ha
Flight Speed	6 – 7 m/s	Route Spacing	4 – 7 m
Mode	(Auto)Route Mode	Spinner Speed	700 – 1000 rpm/min
Scenario	Route Mode + Above water (if have water surface)	Hopper Gate	Standard
Obstacle Avoidance	Turn on	Wind Speed	Below５m/s
Low Speed Ascend	Turn on	Flight Optimization	Auto Route Spacing Adjustment –Turn on Smart Resume – Turn on

By following these guidelines and best practices, you can harness the full potential of agricultural drones, achieving higher productivity and more precise crop management, leading to greater yields and resource efficiency.

DJI Agras T40 Preseason Checklist and Maintenance Guide

Златко Грозданов — Fri, 04 Oct 2024 08:33:54 +0000

The DJI Agras T40, since its launch at DJI AirWorks in Las Vegas in October 2022, has become the spraying drone of choice for both farmers and custom spray service providers, proving to be an indispensable asset for precision agriculture. For many T40 owners, we are about to begin our second season with the Agras T40 as our daily driver. Therefore, it’s essential for agricultural drone operators, farm managers, and custom spray drone service providers to perform preseason maintenance to ensure that their T40 is at the peak of its performance. Read on to see DJI Agriculture’s essential T40 preseason maintenance tips to start the 2024 spraying season on the right foot.

Why a Preseason Checklist is Essential

A preseason maintenance check is not just proactive; it’s a strategic move. The situation you want to avoid at all costs is arriving at the field, pressed by a tight schedule, only to find that your T40 has an issue that could compromise its performance or even sideline it for the day. Ensuring that your T40 and its components are in top condition before you hit the fields can prevent costly downtimes and potential accidents. By laying down a rigorous preseason checklist, you’re fortifying your agricultural operations against the uncertainties that come with technological devices that are exposed to the harsh conditions of the farming environment.

Preseason Maintenance Checklist

Here are some essential steps you can perform to make sure your T40 is ready for the season:

Arms

The arms of your T40 are its supporting pillars. They handle the drone’s weight and are critical for stability.

To start, open the arms up and lock them into place. If the arm glides from the closed to open position with little to no effort, this can be tightened with a 16 mm socket wrench

Next, verify that the arms are securely fastened. Grab each arm at the motor base and try to wiggle it. Loose arms are not just a flight risk; they can also throw off the drone’s calibration, affecting the precision of its spraying pattern. If an arm is loose, you will need a 16 mm socket wrench to tighten the nut.

This is a good time to also check the arm safety locks and make sure they are working correctly – when locking it you should hear it snap into place. If an arm lock is too loose, it can open by itself which is not good. Conversely, if the lock is too tight, it can be not only a hassle to lock/unlock it, but also potential cause for micro-fractures within the carbon fiber of the arms, which can lead to a larger fracture mid-flight. The locking handle tightness can be adjusted with a small 6 mm crescent wrench. With the handle open, there is a hex-shaped rod within the handle that can be adjusted with the wrench.

To finish the inspection of the arms, check for any surface damage. Even superficial cuts and abrasions can be weak points, potentially leading to failure in high-stress situations.

Motors and Props

Start by opening up the pair of props so they are close to 180 degrees, or a straight line. Notice the tightness of each prop and ensure the prop adapter screws have not become loose over time. These are really the only screws that need attention within this area.

Like the arm tightness above, there should be some resistance or tightness when opening the props – it shouldn’t glide open without any resistance.

After verifying prop tightness, glide your fingers along the edges of the props and ensure there aren’t and cracks, chips, or dents in the prop edges. If present, the props must be replaced prior to take-off. It’s important to note that props should be replaced in pairs, along with new prop gaskets.

Continue with a comprehensive visual inspection. Ensure all components, motors, and ESCs are in impeccable condition with no cracks, or chips. Follow up by checking all the screws, making certain they’re tightly fastened and secure.

After securing the components, take a moment to manually spin each motor. This is to detect any resistance or rough movement, which should be non-existent. Encountering difficulty while spinning the motors could point to a potential issue. Should such a resistance or roughness occur, it’s normally caused by coil corrosion, broken bearing or other damages in the motor. Please contact your dealer to have further check.

Spraying System

Preseason is a great time to recalibrate the spraying system. This includes recalibrating all the weight sensors, pumps, and flow meters. On DJI AGRAS App, go into the drone’s Spraying System Settings, add a liter of water into the spraying tank, click ‘Clear Trapped Air’ first to clear trapped air from the sprayer pump hoses, and then do Flow Meter Calibration. Empty the tank, then go into ‘Weight Sensors’ in Spraying System Settings, click ‘Tare Calibration’ to reset the weight display to 0. Then fill your tank with 20 L water, and check whether the payload weight displayed on the upper-right corner is between 16-24L. If so, do Weight Calibration. Lastly, turn on the sprinklers and make sure it can reach its max flow rate, which should be 12 L/min (3.1 gal/min). At the same time, check if there’s any leaks.

Batteries and Chargers

Without a doubt, optimal battery performance, including fast charging, can make or break your operation efficiency. Preseason is a great time to ensure your batteries can fast charge. Inspect the charging ports of each battery and make sure there’s no corrosion or damage, such as green-tinged rust covering the pin.

This is a good time to mention that any dust, dirt, or debris can be cleaned off from the battery ports and the battery pins of the drone using a 95% alcohol solution and a cotton swab or microfiber towel. This kind of cleaning should be checked and done daily to help extend the life of the battery and of the drone.

Next, test each battery in the drone to verify it can hold a charge and power on the drone. Then check that fast charging still works for each battery and your charger.

And in case you missed it, we have recommended storage protocols for your batteries, which you can find here: https://www.youtube.com/watch?v=8FcNYYw44jc

Test Flight

After checking the arms, motors, props, and batteries, you should be ready for test flights that gradually increase the strain on the drone.

Power up your drone and allow it to idle on the ground, and check if there are any errors.
Proceed to a gentle takeoff and hover to let the drone warm up, especially if it hasn’t been used for an extended period.
Conduct a manual flight in an open area. Execute 180 or 360-degree spins to assess the drone’s response. Listen carefully; motors may appear fine visually, but stress can cause them to emit a whining sound when rotating. Perform these tests without additional weight.
Test the T40’s Active Phased Array Radar with a pole or an obstacle in your test field. Be sure to turn on all obstacle avoidance and settings in advance. This is also a good time to check the drone’s altimeter readings by ascending and descending the drone and confirming that the reported altitude of the drone is accurate. This helps verify that the downwards radar is performing properly.
Test the T40’s automatic functions. Create a flight route and have the drone complete it.
Fill with the drone’s spraying tank and fly it manually. This additional weight and pressure will test the drone’s endurance. Run a couple full tanks through the sprinklers to ensure consistent performance.

Spare Parts and Repairs

Before the spraying season begins is a perfect time to stock up on spare parts, tools, and basic repair knowledge and protocols. This preparation can be the difference between a brief delay and a day’s worth of postponed operations. This includes contacting your dealer to confirm recommended aircraft collision protocols so you are prepared should you encounter this scenario.

Parts to Consider

We recommend stocking spares for parts that can be changed quickly in the field and get you airborne in a short time. This includes motors, ESCs, propellers, prop gaskets, and other common quick fixes that are the difference between a 5-10 minute delay vs. a whole day delay. If you have a more serious issue like a crash, a full damage assessment is necessary and a part swap at the field isn’t recommended.

Tools and Organization

Having the right tools is as important as having spare parts. Invest in high-quality tools to avoid strip screw heads or other damage. If you’re doing repairs in the field, a magnetic containers to keep small parts like screws in place and label sections is helpful to ensure you can locate them when needed. It’s also a good idea to have a workbench so you can get the drone off the ground and have an easier time working on it.

Repair Tips and Troubleshooting Strategies

Be systematic in your approach. If a repair becomes necessary, conduct a damage assessment in a well-lit area. If necessary, take pictures throughout the process to help document what you are doing. Each part should be inspected thoroughly. Stay organized; keeping track of what you’re doing is just as critical as the repair itself.

Equip yourself with knowledge. Understanding your T40’s flight logs, error codes, and firmware updates can save you time in the field. If you have an error you aren’t familiar with, you can look up the error code to help narrow down your next steps.

What does agricultural drone spraying of 66.7 million hectares mean to the planet?

Златко Грозданов — Wed, 13 Mar 2024 12:33:44 +0000

The United Nations has predicted that the global population will reach 9.7 billion by 2050. As global warming and energy shortage intensifies, humans are facing unprecedented challenges on multiple fronts such as food, energy, and water supply. This has given rise to the pressing need for green and sustainable agricultural practices.

In 2021, DJI pilots have completed agricultural missions covering a total of 66.7 million hectares of farmland. Besides greater machine efficiency, what else have we contributed to the ecosystem and its sustainable development?

Greener Practices

Reduced carbon emissions by 3.43 million tonnes

Climate change, which has triggered a series of environmental issues such as melting glaciers and rising sea levels, is impacting each of our lives. One of the ways of tackling the climate crisis is by reducing carbon emissions. To this end, China has committed to achieving peak emissions by 2030 and carbon neutralization by 2060. DJI Agriculture is echoing these goals by exploring ways to limit carbon emissions.

In plant protection operations, replacing traditional machines with drones can reduce carbon emissions by 51.45 kg CO2e (carbon dioxide equivalent) per hectare.^[1]For 66.7 million hectares, that’s equal to 3.43 million tonnes of CO2e.

3.43 million tonnes carbon emissions is equivalent to

Carbon absorbed by 161 million trees in a year
Carbon emissions from 1.27 million vehicles
Saved water by 29 million tonnes

The use of drones in farmland management saves around 435 liter of water per hectare compared to manual operations. For 66.7 million hectares, that’s equal to saving 29 million tonnes of water.29 million tonnes water is equivalent to the water intake of 52.72 million residents in a year^[2]

Increased pesticide utilization rate by 10%[3]

The application of agricultural drones can increase pesticide utilization rate by at least 10% compared to manual back-carried spraying. At the pesticide usage rate of 1.5 kg per hectare, 1,000 tonnes of pesticide can be saved by spraying 66.7 million hectares using drones.

Increased safety in farmland management

Pesticide poisoning has been a perennial problem in the industry. The increased use of agricultural drones has made farmland operations safer by protecting personnel from chemical hazards, providing farmers with a healthier, safer work environment.

Providing new solutions to environmental protection

Regreening mines in Xinjiang

Three years ago, several abandoned mines in Fukang City, Changji Prefecture of Xinjiang were found to have caused severe pollution to local environment. In March 2021, DJI’s agricultural partner Tieman plant protection team joined the regreening operations for the mines, where they seeded 666.7 hectares of land using drones and restored its vegetation. This summer, the mines were covered in sweeping green grass and showing vital signs of growth.

Seeding success for mudflats in Zhejiang

In March 2021, Shanghai Mu Ying Ecological Technology scattered 12 million scirpus mariquete seeds on mudflats near the 10-km Baishawan Seawall in the coastal wetlands of Pinghu City, Jiaxing, Zhejiang, using the DJI T30. In four months, the area developed into a green and picturesque ecological attraction. The successful project provides valuable seeding experiences that are replicable in future wetland protection efforts.

Grass seeding on the Tibetan Plateau

The ecological environment in Tibet is fragile owing to a combination of factors including its high altitude, cold climate and unique topology and aquatic environment, which have led to serious desertification and land degradation issues. In May 28, 2021, the DJI plant protection team conducted its first drone grass-seeding mission across nine counties in four cities, namely Lhasa, Shigatse, Shannan, and Nyingchi, aiming to improve forestation capabilities in snowy plateaus. The operation covered an area of 44,320 hectares, with around 323.01 tonnes of seeds spread.

Digital agriculture for precision farmland management

Variable spread lowered fertilizer consumption in rice and wheat fields by 10%

In 2021, Jiangsu Farming onboarded DJI’s digital agricultural solutions in the operation of its farmland of 86,700 hectares. During the pandemic, the company embraced digital production management by deploying drones for autonomous patrols and remote monitoring of crop growth. With the drone’s variable and precise spreading technology, they were also able to reduce fertilizer consumption in their rice and wheat fields by 10%.

Precise chemical control and defoliation for cotton crops

In May 2021, Chen Gongxu from Shihezi City, Xinjiang adopted DJI’s digital agricultural solutions for his cotton fields of more than 333.3 hectares. He used a multispectral drone to survey cotton growth in different areas and to generate treatment maps for spraying plant promoters in variable amounts. By relying on multispectral data, the drone could also spray defoliants in precise quantities. This not only minimizes the use of defoliants but is also friendlier to the land and the environment, all while ensuring proper defoliation of the crops. As of September 28, Chen’s cotton yield saw an increase of 900 kg to 9,150 kg per hectare and a reduction in chemical usage by 20%.

Better Growth, Better Life.

[1] 1.Diesel is the main source of fuel for conventional tractors. Based on the IPCC Guidelines, the calorific value per unit for diesel fuel used by agricultural machinery is 42,652 KJ/kg, with a CO2 emission factor per calorific value unit of 74.1 kg/GJ and carbon oxidation factor of 0.98. Therefore, the CO2 emission factor for diesel fuel is 3.10 kg CO2e/kg. In 2016, the median fuel consumption for mechanized plant protection operations in China was 16.8 kg/ha, which translates to carbon emissions of 52.05 kg per hectare. Aerial application drones are mostly powered electrically and their spraying actions are mainly driven by gasoline generators. The calorific value per unit for gasoline is 43,070 KJ/kg, with a CO2 emission factor per calorific value unit of 69.3 kg/GJ and carbon oxidation factor of 0.98. This means the CO2 emission factor for gasoline is 2.93kg CO2e/kg. In plant protection operations, the gasoline consumption per hectare is approx. 0.21 kg/ha, which translates to carbon emissions per hectare of 0.63 kg CO2e. Agricultural drones are more energy efficient than conventional machinery, able to reduce carbon emissions by 51.45 kg CO2e per hectare.

[3]In the paper “The impact of the widespread use of aerial application drones on improving the pesticide utilization rate in China” by Yuan Huizhu, et. al. from the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, pesticide utilization rates achieved by aerial application drones with low tank capacity flying at low altitudes for spraying operations on rice, wheat and corn were 49. 1%, 57. 1%, and 52. 70% respectively, compared to manual back-carried spraying with large tank capacity. According to data from the Ministry of Agriculture and Rural Affairs, the fertilizer utilization rate for the three main crops, namely rice, wheat and corn, in 2020 was 40.2%. Compared to manual back-carried spraying with large tank capacity, agricultural drones can improve pesticide utilization rate by at least 10%.
