Narrative on NRI Soil Biodiversity Project – 1996 CRIS Report

In 1996 we completed the second year of field sampling. Analysis of 1995 Arlington data indicates that for several of the soil organisms monitored, taking 3 to 6 samples per plot, and bulking them, will give the lowest standard error for the effort expended. Analysis of sampling date has indicated that eight dates are not […] More »

Analysis of Soil Macroarthropods Associated with Pitfall Traps in the Wisconsin Integrated Cropping Systems Trial, 1995

The health of soil ecosystems is often quantified using biological diversity indices to gain insight into the “stability” of these systems. In general, a greater diversity of soil fauna inhabiting a system help establish healthy soils because the interactions of a richer complex of taxa (e.g. species) contributes to a more stable food web. Macroarthropods […] More »

Pitfall Trap Analysis of Soil Macroathropods associated with WICST – 1994

Our hypothesis in this study of arthropod diversity continues to be that  the level and frequency of soil disturbance (both physical and chemical) in the various cropping systems influence the numbers and kinds of arthropods inhabiting the plots.  Differences in arthropod populations could contribute to as well as result from changes in soil characteristics. In […] More »

Pitfall Trap Analysis of Soil Macroarthropods Associated with the Wisconsin Integrated Cropping Systems Trial, 1993

The Wisconsin Integrated Cropping Systems Trial has become a forum for examining the ecological ramifications, both short and long term, of different approaches to farming and philosophies of land stewardship. Like several other research groups, we have focused on the soil biota as one measure of environmental impacts of agriculture. Our operational hypothesis for our […] More »

A Survey of Soil Macroarthropods associated with Corn in Alternative Cropping Systems – 1992

WICST provides a unique laboratory for examining the ecological ramifications, both short and long term, of different approaches to farming and philosophies of land stewardship. Much of the ecological ‘action’ will take place in and on the soil, and will be related to the health of the soil as measured in chemical, physical, and biological […] More »
