Drones and Unmanned Aerial Vehicles (UAVs)

Drones provide aerial imagery for crop monitoring, spraying, and mapping. Unlike manual scouting, they can cover large areas in minutes with high accuracy. Multispectral drones detect variations in crop color and canopy density—key signs of water stress or nutrient shortage. Spray drones deliver pesticides evenly, saving time and reducing exposure risk to farmers. Example: DJI Agras drones are used globally for crop spraying and yield mapping. Advantage: Cuts chemical use by 30–50%, increases spraying precision, and enhances environmental safety.
