A Comparison of Low Input Systems on WICST

Marginal profits, increasing pest pressure, and concern for pollution hazard have resulted in increased interest in including small grains in corn-soybean rotations and using less inputs.  Data from the WICST trials show environmental advantages of using a chemical free three-phase system but yields were often lower than in the high input systems.  Researchers have [...] More »

Organic and Conventional Production Systems in the Wisconsin Integrated Cropping Systems Trial: II. Economic and Risk Analysis 1993-2006

This article, the second in a series looking at the Wisconsin Integrated Cropping Systems Trial (WICST), reports on the profitability of six conventional and organic systems, with a focus on net returns and associated risk exposure. Several pricing scenarios were compared to evaluate the impact of government programs and organic price premiums. When net return [...] 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 »

Weed Seed Bank Changes on WICST: 1990 to 1998

Crop management systems influence various aspects of the soil, not the least of which are weeds. The rotation, tillage system, intensity of herbicide use, and integration (or lack there of) of herbicides with other control practices will certainly affect the weed seed bank. While this principle is well recognized, seed bank data to [...] More »

Cropping system three Chemlite satellite trial-Arlington, 1995 and 1996

In spite of very low corn yields in 1992 and 1993, and below average wheat yields, almost every year, Cropping System 3 (CS3) has been at least as profitable as the continuous corn system. It is not clear however, how much of the profitability of CS3 is due to the zero purchased input philosophy [...] More »
