	Yield Map Maps of crop yield can be made using agricultural GPS systems. The map shown here indicates how crop yield varies across a field. These maps can be created during harvesting, allowing farmers to accurately plan how the fields should be used and fertilized for future crops. Graphic courtesy Case Corporation.
