Organic System Yields and Yield Trends in the Wisconsin Integrated Cropping Systems Trials

The USDA-ERS held a conference in Washington D.C. from March 16-18 on organic farming systems research that included several long-term systems research trials across the USA.  These slides summarize long-term yield trends on organic and conventional crops in WICST.

Organic and Conventional Production Systems in the Wisconsin Integrated Cropping Systems Trials: I. Productivity 1990-2002.

Abstract: During the last half-century, agriculture in the upper U.S. Midwest has changed from limited-input, integrated grain-livestock systems to primarily high-input, specialized livestock or grain systems. This trend has spawned a debate over which cropping systems are sustainable and led to the general question; can biologically diverse, low-input cropping systems be as productive as conventional […] More »

The Wisconsin Integrated Cropping Systems Trial: Combining agroecology with production agronomy

Abstract: Two large-scale (25 ha) trials were initiated in 1989 in Wisconsin to compare six alternative prodution systems regarding productivity, profitability, and environmental impact. The project was desiged and is managed by a coalition of farmers, extension agents and research personnel.. Deliberations between porduction-oriented and ecologically oriented team members resulted in a factorial design, with […] 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 »
