SnapPlus is a nutrient management planning program that includes the entire RUSLE2 program and the climate, soil, and
selected parts of the management databases for Wisconsin
590 Plan that meets guidelines for: Nitrogen loss risk (rate, location, timing) Sediment loss risk (RUSLE2) Phosphorus loss risk (P Index)
