Abstract

Information on phosphorus (P) loss from surface runoff in fields managed with different cropping and P management systems is scarce. Swine manure can supply nitrogen (N), P, and K (potassium) for crops. Continued use of N-based manure rates can result in P buildup in the soil, mainly in continuous corn or when manure is applied for both corn and soybean production. Excessive soil P and P applications increase the risk of P loss from fields and of water quality impairment.
