Summary of the 5th year of WICST with focus on core trial plus satellite activities and soil biodiversity research

Relevance of Biodiversity to the Sustainability of Agricultural Systems

Biodiversity is widely considered to be an important measure of ecosystem health, underpinning ecosystem structure, function, and sustainability. Agricultural systems comprise the majority of all terrestrial ecosystems; thus, agriculture may be especially important to maintaining biodiversity. Past research has produced conflicting evidence on whether biodiversity is key to agricultural sustainability, and which agricultural [...] More »

On-farm evaluation of legume seeded after winter wheat

Growers whose crop rotation includes winter wheat can reduce nitrogen costs by planting a legume green manure with or after wheat.  The objective of this study is to compare two promising legumes” berseem clover and annual medic to hairy vetch for productivity under real farm conditions.

Monitoring soil test P and K in the WICST trial

ABSTRACT Farmers are concerned about the effects of low-input cropping systems on soil fertility, even on the historically rich and heavily manured and fertilized prairie soils of Wisconsin. Soil test phosphorus (STP) and potassium (STK) changes in the top 6in. of the soil profile are being monitored in the WICST trial since 1990. The [...] More »

Monitoring fall nitrates in the WICST - 1995

ABSTRACT Minimizing the amount of inorganic N in the rooting zone following the crop harvest reduces the potential for nitrate-N (NO3-N) losses via leaching to groundwater. Soil NO3-N levels in the top 3 ft. of the soil profile are being measured since 1990 in all six cropping systems of the WICST. Among the cash [...] More »
