2. Agriculture: keeping a closer eye on crops
Farmers find drones to be highly useful for managing their crops. Drones can help farmers plan the proper use of water, pesticides and fertilizers. By photographing crops from above, farmers can monitor growth and quickly respond to problems — such as inadequate irrigation — that can reduce crop yield. While relatively new to farmers in the United States, the use of drones is more common in Japan, where they are used to track the progress of rice crops.
