Title: Improving Nitrogen Management for Corn on Irrigated Sandy Soils.
Principle Investigator: Larry G. Bundy, Dept of Soil Science, UW-Madison.
Objective: For corn production on sandy irrigated soils: Determine optimum times of N application; Determine optimum N rates using several N fertilizer materials; Evaluate use of a nitrification inhibitor with selected N sources and times of application.
Funding Level: $7,500, $7,800, $8,200
Duration: 3 years
Title: Tannin-bound Protein Fertilizers for Rhododendrons – Feed the Crop, Starve the Weeds?.
Principle Investigator: Kevin R. Kosola, Dept of Horticulture, UW-Madison.
Objective: To assess the potential for developing tannin-bound protein as a fertilizer nitrogen source which would be available to ornamental Ericaceae, but not to common weeds.
Funding Level: $8,156
Duration: 1 year
Title: Determining Tuber Calcium Accumulation Efficiency, Using Various Fertilizers, for Major Potato Cultivars.
Principle Investigator: Jiwan P. Palta, Dept of Horticulture, UW-Madison.
Objective: The goal of the study is to develop calcium fertilization recommendations for potatoes grown in Wisconsin.
Funding Level: $18,500, $19,500, $19,500
Duration: 3 years
Title: Impact of Calcium and Nitrogen Fertilizer Application Timing on Potato Maturity.
Principle Investigator: Alvin J. Bussan, Dept of Horticulture, UW-Madison.
Objective: Determine the impact of the time of application of nitrogen fertilizer on maturity of potato; Determine the impact of time of application of calcium fertilizer on maturity of potato; Qunatify the response of potato sugars, in particular sugar ends, specific gravity, and other potato tuber quality factors to time of application of calcium fertilizer.
Funding Level: $10,000, $10,000
Duration: 2 years
Title: Response of First-year Corn Grown on Erodible Soils to Conservation Tillage and Fertilizer Placement.
Principle Investigator: Richard P. Wolkowski, Dept. of Soil Science, UW-Madison.
Objective: To examine the response of first-year corn following soybean to the application of a fertilizer containing both P and K. Row and broadcast placement will be compared in four different conservation tillage systems that have varying degrees of soil disturbance and residue incorporation. The goal of the study will be to demonstrate productive conservation tillage systems for grain crops on the highly erodible soils of Wisconsin and nearby states.
