Drones for Spraying and Field Mapping
On large fields, a drone can map crop stress and spray precisely in hours instead of days. We help you judge when it pays.
Drones carry cameras to reveal uneven growth, water stress and pest hot spots, and spray drones can treat large areas quickly with less water. Mapping from above helps you decide where to apply fertilizer or irrigation.
They suit large or hard-to-reach fields, and service providers can make them affordable without buying one. We advise on whether it pays for your farm and on regulations.
