Fertilizer and Swine Manure Management Systems Impacts on Phosphorus in Soil and Subsurface Tile DrainageIowa State Research Farm Progress Reports

AbstractSwine manure and fertilizer can be used to supply the nitrogen (N) and phosphorus (P) needs of crops. Excess P application sometimes applied with N-based manure for corn increases the risk of P loss and water quality impairment. Poor water quality in Iowa streams and lakes due to excess P has prompted questions about the impact of cropping and nutrient management systems on P loss from fields.
