Objective: To determine the effect of N- and P-based manure application rate standards and tillage on: 1)dissolved P,
bioavailable P, and total P losses in runoff; 2)crop removal of P, changes in soil test P levels, and soil P stratification; and 3)
corn grain yield and moisture content for determining economic returns based on inorganic N fertilizer inputs, grain drying costs, yield.
