GPS Receivers and Farming

Farmers use tractor-mounted GPS receivers to record location. This information helps determine how much fertilizer, weed control, and water is needed in various locations of the field. Additional soil analysis combined with market information about predicted crop prices helps farmers decide what is the best crop rotation.

In precision agriculture, farmers combine GPS data with other information such as soil samples, moisture content, weed density, and crop yield in a computer spreadsheet.
