Soil organic carbon changes in six Midwestern cropping systems in southern Wisconsin

The purpose of this study is to compare the six cropping systems of WICST over their initial 12 years at the wetter LAC and better-drained ARL sites for their impact on soil carbon concentrations. We hypothesize the following: 1) initial SOC levels will be higher at the wetter site (LAC>ARL); 2) since all the systems […] More »

The Wisconsin Integrated Cropping Systems Trials: Yields, Yield Variability, and Yield Trends 1990-2002.

In 1990, a large scale, and long-term study entitled the Wisconsin Integrated Cropping Systems Trial (WICST) was initiated at two locations in southern Wisconsin. The purpose of the project was to compare alternative grain and forage-based systems using three performance criteria: 1) productivity; 2) profitability; and, 3) environmental impact. An obvious initial criterion in comparing […] More »

1992-1998 Economic Analysis of the Wisconsin Integrated Cropping Systems Trial

The 1998 economic analysis for the Wisconsin Cropping Systems Trials marks a new approach to evaluating the systems. In the past, the economic analysis has been compiled by different economists and agronomists that evaluated the data a year at a time. This year’s evaluation uses a more consistent process over 1992-1998 for Cropping Systems (CS) […] More »

Addressing the challenges of sustainable agriculture research and extension at land-grant universities: Radially organized teams at Wisconsin

Abstract: Researchers at land-grant universities are under pressure to widen their research objectives, which requires them to expand their inquiry from a disciplinary base to a systems level, to include farmers and nonuniversity organizations as research collaborators, and to communicate with broader sectors of the public, such as consumers and policy makers. However, there are […] More »
