2009 Projects

Project: 229-08 

Title: Development of annual and perennial cover cropping systems for integration into vegetable crop rotations. 

Principle Investigator: A.J. Bussan, Dept. of Horticulture, UW–Madison. 

Objective: Quantify the ability of a spring seeded annual cover crop to accumulate or produce nitrogen that can be utilized by a subsequent snap bean crop. Determine the stage of cover crop development that provides the most available nitrogen at the critical time for uptake by a subsequent snap bean crop. Quantify residue levels and harvest quality of snap beans under different incorporation techniques. Identify optimal timing for establishment of red clover in snap bean. 

Funding Level: $6,768 
Duration: 2 years

Project: 231-08 

Title: Nitrogen management and replant decision recommendations for winter wheat production systems. 

Principle Investigator: Shawn Conley, Dept. of Agronomy, UW–Madison. 

Objective: Quantify the effect of N rate and timing (fall, spring, split-spring) on winter wheat yield and grain quality. Quantify the effect of spring nitrogen rate and % winterkill on soft red winter wheat yield and grain quality. Develop guidelines for wheat N management and to assist growers in managing winterkill replant decisions in winter wheat. 

Funding Level: $16,541 
Duration: 2 years

Project: 234-08 

Title: Understanding plant availability of manganese in glyphosate resistant soybean systems. 

Principle Investigator: Carrie Laboski, Dept. of Soil Science, UW–Madison. 

Objective: Quantify the effect of glyphosate in Mn availability in GR soybean systems. Develop new Mn management guidelines for GR soybean systems. 

Funding Level: $12,304 
Duration: 3 years

Project: 235-08 

Title: Comparison of the nitrogen use efficiency and nitrogen needs of corn hybrids with and without transgenic corn rootworm resistance. 

Principle Investigator: Carrie Laboski, Dept. of Soil Science, UW–Madison. 

Objective: Determine if corn hybrids with the transgenic corn rootworm resistant gene vary in their N use efficiency and N need compared to non-resistant hybrids. Obtain additional N response information to add to Wisconsin’s database upon which corn N rate recommendations are made. 

Funding Level: $11,009 
Duration: 3 years

Project: 236-08 

Title: Maximizing nitrogen use efficiency, yield, and quality of grass pasture through the use of nitrogen fertilizer technologies. 

Principle Investigator: Carrie Laboski, Dept. of Soil Science, UW–Madison. 

Objective: Evaluate the effectiveness of various N fertilizer technologies to improve N use efficiency, yield, and quality of grass pasture. 

Funding Level: $19,362 
Duration: 2 years

Project: 238-08 

Title: Potassium fertilizer requirement for corn and soybean and soil test potassium drawdown. 

Principle Investigator: Carrie Laboski, Dept. of Soil Science, UW–Madison. 

Objective: Determine at what soil test level corn yields begin to decline and to measure soil test K drawdown the third growing season after potash application. 

Funding Level: $10,673 
Duration: 1 year
