Abstract
A system is used for applying fertilizer to a field. A nutrient requirement map is first obtained for the field indicating nutrient requirements for a plurality of locations in the field. A first blend of fertilizer is calculated based on the nutrient requirements. Fertilizer components are blended to form the first blend. The first blend is loaded into a first bin of an applicator. The first blend is then applied with the applicator at a first application rate, wherein the first application rate varies as the applicator travels across the field based on nutrient requirements corresponding to the location over which the applicator is then traveling.
