    The Minnesota Phosphorus Index: Assessing Risk of Phosphorus Loss from Cropland
    (University of Minnesota Extension Service, 2006) Lewandowski, Ann; Moncrief, John; Drewitz, Matt
    The Minnesota Phosphorus Index (MN P Index) is a model with the primary purpose of estimating P loss risk. The computerized version of the model is available in the zipped folder on this record. The MN P Index is used when a more accurate estimate is needed (e.g., on sites with multiple risk factors), or to estimate P loss risk unrelated to manure applications (e.g., to identify P loss sites within a watershed). The MN P Index helps users identify and refine site-specific methods to reduce P loss by considering the interaction of a wide range of risk factors including landscape characteristics, cropping and tillage practices, and P application methods.
