SnapPlus is a Nutrient Management Planning software program designed for the preparation of nutrient management plans in accordance with Wisconsin’s Nutrient Management Standard Code 590. SnapPlus will calculate:

• Crop nutrient (N, P₂O₅, K₂O) recommendations for all fields on a farm taking into account legume N and manure nutrient credits consistent with University of Wisconsin recommendations
• A RUSLE2-based soil loss assessment that will allow producers to determine whether fields that receive fertilizer or manure applications meet tolerable soil loss (T) requirements.
• A rotational Phosphorus Index value for all fields as required for using the P Index for phosphorus management.
• A rotational P balance for using soil test P as the criteria for phosphorus management.
