Agricultural UAV In Aerial Application

- May 10, 2017-

Aerial application, or what was formerly referred to as crop dusting, involves spraying crops with crop 

protection products from an agricultural drone or plane. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as aerial topdressing in some countries.

Agricultural aircraft are highly specialized, purpose-built aircraft. Today's agricultural aircraft are often powered by turbine engines of up to 1500 hp and can carry as much as 800 gallons of crop protection product. Helicopters are sometimes used, and some aircraft serve double duty as water bombers.

 With the technical development of flight control,Aerial application at night is mostly liquid spray. In high temperature areas, the insects would travel down in plants in daytime and return to the top at night. The aircraft — both fixed wing, multi-rotor agricultural drone and helicopters. Some aircraft were equipped with an elongated metal wing called a spreader, with inbuilt channels to direct the flow of dust such as sulfur, used on melons as a pesticide and soil amendment. GPS units replaced the flaggers due to new laws restricting use of human flaggers with some pesticides. GPS systems also provide precise guidance for the applicator.

Aerial application accounts for just fewer than 20% of all applied crop protection products on commercial farms. Approximately 1,350 aerial application businesses are in the U.S. and 1,430 non-operator pilots. 94% of aerial application business owners (operators) are also pilots. Aerial application businesses are located in 44 states – all but Connecticut, Hawaii, Nevada, Rhode Island, Vermont and West Virginia.

Today’s agricultural aircraft use sophisticated precision application equipment such as: GPS (global positioning systems), GIS (geographical information systems), Aircraft Integrated Meteorological Measurement System (AIMMS), real time meteorological systems, flow control valves for variable-rate applications, single-boom shutoff valves and smokers to identify wind speed and direction.

Beginning in the late 1990s, unmanned aerial vehicles are also being used for agricultural spraying. This phenomenon started in Japan and South Korea, where mountainous terrain and relatively small family-owned farms required lower-cost and higher precision spraying. As of 2014, the use of UAV crop dusters. Now with the pesticide spraying and flight control development, agricultural spraying drone is being expanded to the United States for use in spraying of vineyards.
