Spray drones are unmanned aerial vehicles designed to apply pesticides, fertilizers, and other agricultural chemicals over crops. They are equipped with tanks and nozzles that allow for precise spraying, helping farmers cover large areas quickly and efficiently. This technology reduces the need for manual labor and minimizes chemical waste. These drones can navigate various terrains and reach areas that may be difficult for traditional equipment. By using GPS and mapping technology, spray drones can ensure even distribution of substances, improving crop health and yield while also promoting sustainable farming practices.
