Upgraded spraying system for accuracy and efficiency

The DJI AGRAS T20 can carry a maximum payload of 20kg and the layout of the nozzles have been optimised to achieve a 20% improvement on the uniformity of spray droplets and the effective spray width of seven meters. The DJI AGRAS T20 is equipped with eight nozzles and high-volume pumps that can spray at a rate of up to six l/min. A highly optimised wind field produces droplets ideal in size and consistency. The new four-channel electromagnetic flow meter design can monitor and control the four hoses individually, ensuring an efficient flow rate for each nozzle.

The DJI AGRAS T20 is equipped with an Omnidirectional Digital Radar system, which is able to detect obstacles from all horizontal directions. It can also automatically circumvent obstacles while flying over various terrains, ensuring a high level of operational safety. With this radar system, the AGRAS T20 can adapt to some of the most challenging environments thanks to its strong resistance to dust and water thanks to an IP67 rating.

In addition, the DJI AGRAS T20 enables users to set flight and operation parameters. With a built-in RTK centimetre-level positioning system and RTK dongles, centimetre-level waypoint recording is enabled, strengthening operations greatly and ensuring precision spraying. It also comes with a real-time FPV camera and two searchlights, providing users with comprehensive live views even during low-light operations.

According to DJI, the modular design of the DJI AGRAS T20 folds and unfolds in seconds, making it more portable than other agriculture drones. The spray tank and battery are both swappable, reducing downtime and increasing workflow significantly. The drone comes equipped with a new programmable DJI AGRAS Smart Controller 2.0 and the DJI AGRAS mobile application. In addition, the smart controller comes with an ultra-bright 5.5-inch display, which remains readable even under direct sunlight and bright operation conditions. It also supports external battery packs for lengthy or heavy workloads.

DJI said that with a comprehensive suite of DJI agriculture solutions, operating in broadacre farmlands, orchards, or grasslands has become a lot easier. The DJI agricultural solution packages are designed to monitor crop health and generate variable treatment procedures. By using the P4 Multispectral, operators can scan target areas and generate multispectral charts that provide actionable insights into crop health and help formulate variable spraying and seeding maps.

The '3D Flight Route Planning' solution helps the operator navigate through challenging terrains. By using the Phantom 4 RTK, operators can scan and map target areas, making it easier to identify all aspects of the field. In Orchard mode 3.0, 3D flight routes can be generated based on the shapes of each tree after they are identified and users can conduct efficient spraying with their DJI AGRAS T20.
