Corn Fungicide Spraying with DJI Agriculture Drones in the US

How drones are helping US corn farmers elevate efficiency Corn farming has been the backbone of U.S. agriculture for decades, with vast fields stretching across states like Kentucky. Yet, the industry is not without its challenges. Enter agriculture drones, the latest innovation set to revolutionize how farmers manage their crops.This case study dives deep into the role of drones in corn fungicide spraying, exploring its advantages, challenges, and real-world applications. With the advent of drone technology, farmers now have a powerful tool at hand to increase convenience and cost performance. The Challenges Faced by Corn Farmers 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. Introducing L. Hust Farms L. Hust Farms, founded in 1950, is a prime example of how modern technology can transform traditional farming practices. Based in Kentucky and owned and operated by brothers Josh and Kyle Lancaster, the farm spans over 12,000 acres of corn and soybean fields. They began using DJI Agriculture drones in 2021 and have since experienced substantial improvements in convenience and cost performance. This case study presents findings from their 2024 season where they used drones to complete all of the fungicide applications for their corn, taking place from July 7th to August 28th. The Decision to Use DJI Agriculture Drones The Lancaster brothers first learned about DJI Agriculture drones in 2021 and quickly saw the potential benefits. They were interested in deploying a solution that could cheaply and flexible protect their crops, and that was available for use at the precise moment when needed. By 2023, they had fully integrated two DJI Agras T40 drones into their fungicide application process. The T40 models used by L. Hust Farms offer several advantages that make them ideal for corn fungicide spraying. These include convenience, reduced operational costs, and the ability to work in post-rain conditions without causing soil compaction. Application Details (2024 Fungicide Spraying Season) The fungicide application covered 10,420 acres of corn and soybean from July 7th to August 28th, with a total of 308 flying hours. The farm’s terrain featured medium sections with rolling hills and tree lines. The drone solution included two T40 drones, two DJI generators, six batteries, a DJI Relay, the DJI SmartFarm app, a custom Ag spray drone trailer, and a spreader system. Flying parameters were set at 2 GPA, a speed of 32 ft/s, a 28 ft spacing distance, a height of 10 ft, and a medium droplet size. Year Acres Covered Application Period Total Flying Hours 2023 6,574 acres July 1st to August 15th 170 hours 2024 10,420 acres July 7th to August 28th 308 hours Parameter T50 / T40 Application Rate 2 GPA (18.7 L/ha) Droplet Size 320 μm Flight Speed 32.8 ft/s (10 m/s) Route Spacing 28 ft (8.5 m) Height Above the Crop 10 ft (3 m) The Workflow for Corn Fungicide Spraying The workflow for applying fungicide is straightforward and efficient. Drone-based corn spraying involves a series of well-coordinated steps, from flight planning to data analysis and the actual spraying process. 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. Their vehicle is referred to fondly as “Optimus Prime” by DJI Agriculture Solution Engineer Michael Zhang. Recommended Flight Parameters for Corn Fungicide Spraying Successful drone operations depend on various parameters such as flight speed, operation height, and nozzle type. For L. Hust Farms, the drones operated at a speed…

DJI Agras T40 Preseason Checklist and Maintenance Guide

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…

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

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. [2]A human’s average water intake…

High-precision Plant Stand Count for Corn, Sunflower and Sugar Beet by a Drone and AI

Plant stand count is an essential task in yield management. It allows growers to estimate the plant population, density, germination rate, and plant health and make timely decisions that finally affect the yield. Common manual methods of plant stand counting have helped growers for decades. They are based on visual inspection and plant calculation on small pre-defined field areas. However, these methods are laborious and far from accurate. Fragmented plant stand count does not provide the complete picture, and problem areas with uneven emergence or weeds might be overlooked. The lack of information on the field eventually leads to a waste of resources and less profitable decisions. New technologies like drones and AI leverage the opportunity to make Agri operations smarter and more efficient. With this innovative approach, growers can now receive accurate data, make timely decisions and sustainably maximise the yield. Surprisingly, this is not as complicated or costly as it might seem. This article covers precise plant stand count using an off-the-shelf drone and Proofminder’s trained AI algorithm for accurate yield assessment and the following insights on the field. You will find practical tips on image collection and recommended approach for corn, sugar beet and sunflower, but the information is also useful for other field crops, vegetables and orchards. If you have a drone or considering buying one to turn a tedious task into an interactive process and get a high-precision result, keep reading. You will find drone requirements, flight tips and common mistakes, and learn how to get a precision stand count report in a few hours with an innovative AI farming platform. Why and when do you need a precise plant stand count? There are situations when a low accuracy report is acceptable, but it is absolutely essential to have a precise one if you aim to: Check the sowing quality, especially if you are producing seeds; Understand zones of varying productivity in the fields; Receive accurate data during R&D projects; Estimate the yield precisely in the early stages; Spot rogues; Make timely decisions, i.e., partially replant the field; Increase the yield potential to meet the production goals. What are benefits of automated plant stand count? On the automatic report generated by Proofminder platform, you can see Plant & row density; Precise plant stand count; Each plant is marked on the field with precise coordinates; Plant distinguished by phenotype, in this case – male and female plants of hybrid corn are marked with a different colour; Zoom-in feature to analyse specific zones, rows or plants. When is the best time for plant stand count using a drone and AI? Estimating the number of plants and their density is crucial for early-season yield management. The accurate information here is a chance to save the yield if something goes wrong and improve the harvest. To gather proper images for further analysis, consider the tips about plants and the weather. The plant should be big enough to be seen from the air, but the leaves are not yet too close to each other to distinguish plants and estimate the density. As an example, for the precise stand count of corn, the plant should have about 3-7 leaves (V3-V7 vegetation stages). The weather should be stable during the footage, thus the lens can adapt to the conditions whether it is sunny or cloudy. Also, it should not be too windy, note that the wind speed may greatly vary depending on the altitude. Which altitude is right for a stand count? Find below! Figure 1 Corn field​ Figure 2 Manual plant stand count of corn​ Capturing images by a drone – instructions and tips The ideal resolution for plant stand count by a drone and intelligent software depends on the plant and the goal. For precise stand calculation of corn, sunflower, sugar beet, and some other field crops and vegetables would be 0.8 cm per pixel or less. What does it imply, and what kind of drone is suitable? The widely available DJI Phantom 4 Pro V.2. can be a good entry-level option for that job, similarly, the DJI Phantom 4 RTK is also a great option if you want a professional drone with high precision positioning. You will need to fly at 18-30 meter altitude to get the indicated resolution. Be aware that some of the Integrated controllers (the Plus versions) limit the flight altitude to 25m above the ground so if you want to count small crops and fly low, you would rather choose the simple controller and instruct the drone from your mobile or tablet.  The ideal speed to capture detailed images would be between 3-5 m/s depending on the altitude and the wind conditions. Using this drone, you can proceed at about 25-30 hectares per day if you have enough batteries; mind you: you can charge them on the site. Proofminder works on novel ways to capture images and foresee the possibility in the near future to capture up to double of this area per day by a Phantom 4 drone.   There are ways to extend the area of image capturing in the near future. Proofminder team foresees this possibility and works to double the area captured per day by a Phantom 4 drone. Figure 3 Shooting images for plant stand count by DJI Phantom 4​ Things to avoid; the Top-10 common mistakes in drone footage: Wrong exposure setting, not properly assessing the weather, resulting in over- or underexposure. Overexposure is more of a problem than underexposure, so if you need to choose between cloud and sunny, and you are not sure, you can safely go for sunny. Too much wind or unstable weather conditions result in blurry images. Not equipped with sufficient memory cards, make sure you have at least a 64 GB card for ~40-50 hectares of land. Not enough batteries and/or chargers to fly continuously during the day. Shooting after rain may require some recalibrations because the plant on the wet soil may not be visible enough, keep this in mind. Not flying with the right amount…
