Refine and Regionalize Southern Phosphorous Assessment Tools Based on Validation and State Priorities

The major objective of the project is to coordinate and advance P management in the southern region by ensuring that most southern P assessment tools have been tested based on guidance in the 2011 NRCS 590 standard and compared to water quality data, and that these tools produce more consistent results across physiographic regions in order to promote greater similarity between southern state P Index ratings and recommendations. The secondary objective of this project is to work across regional and physiographic boundaries outside the southern region to coordinate and advance P management.
