Soil Nutrient and Manure Research at The University of Vermont Phosphorus Index to Improve Nutrient Management on Vermont Farms

UVM Extension and NRCS

The Phosphorus (P) Index is a tool developed to assess the potential for P runoff from individual fields based on soil and field characteristics and management practices (erosion, runoff class, soil test P, manure and fertilizer rates and method of application). The P Index could be a useful addition to nutrient management planning and could be used to prioritize implementation of BMPs. As a pilot project to evaluate possible further use of the P Index in Vermont, we developed P indices for 19 fields on eight Vermont dairy farms, primarily in the Champlain Valley. Preliminary results show that most of the fields had P index values in the medium category, but a few were in the high range. We are currently working with NRCS-VT and the VT Department of Agriculture to incorporate the P Index into state nutrient management planning programs. We are also participating in a national project headed up by NRCS to adapt a P Index to states or regions.
