Abstract
Revised guidelines for the Iowa State University (ISU) phosphorus (P) recommendations and ISU P management may be needed. This project utilized fertilizer and poultry manure P and experiments at research farms and producers' fields with corn-soybean or alfalfa-corn rotations to evaluate several P management practices and provide new knowledge about P management.
