Drones have wide applications in agriculture. Farmers can quickly understand the health of their crops through reviewing images, thermal, and slope information. A wide variety of drone platforms accommodate 1 acre or 100 acres with deployment in minutes. Sensors carried by the drone can track changes in crop health over time. The return-on-investment can be achieved quickly by preventing lost crops through lack of visibility. Corrective action can be done on a select section of crops vs. treating the entire plot.
