Managing Manure P to Protect Water Quality

Title: Managing Manure P to Protect Water Quality

Authors: John A. Lory

Summary: Manure is an excellent phosphorus fertilizer and can be used to meet the phosphorus needs of the crop. Application of manure according to nitrogen needs often results in over-application of phosphorus. Excess phosphorus in runoff into streams, wetlands, and lakes will reduce water quality. Minimizing runoff potential on high-P soils can reduce the amount of P entering surface water.
