Title: Nitrogen- and Phosphorus-Based Manure Application Rate Effects on Phosphorus in Runoff.
Principle Investigator: Larry G. Bundy, Dept of Soil Science, UW–Madison.
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.
Funding Level: $5,950, $18,630, $18,930
Duration: 3 years

Title: Evaluation of the Amino Sugar Nitrogen Soil Test for Predicting Optimum N Rates for Corn.
Principle Investigator: Larry G. Bundy, Dept of Soil Science, UW–Madison.
Objective: To evaluate the amino sugar N test method (Illinois N test) for predicting corn N needs by applying this test to stored soils from numerous N response experiments with previously determined optimum N rates and associated N test results.
Funding Level: $12,500, $12,500

Title: Field Calibration of the Amino Sugar Nitrogen Soil Test in Wisconsin.
Principle Investigator: Larry G. Bundy, Dept of Soil Science, UW–Madison.
Objective: To calibrate the amino sugar N test method (Illinois N test) for predicting the optimum corn N rates in Wisconsin using established experiments with a range in N availability.
