Soil erosion, soil conditioning index, soil tillage intensity rating and fall soil nitrates summary from WICST dataset

Maintaining and increasing crop production requires maintaining soil quality. Jokela et al (2011) summarized the 18-year impact of the WICST cropping systems on a suite of soil quality factors (e.g., aggregate size, bulk density, microbial biomass, total organic carbon, potentially mineralizable N) that were subsequently integrated into a Soil Quality Index (SQI). The highest ranking […] More »

Earthworm Ecology in Agriculture: 1990 and 1991 Data from the Wisconsin Integrated Cropping Systems Trial

Earthworms are considered biological indicators of soil health (Curry and Good, 1992; Daugbjerg et al., 1988; Lavelle et al., 1989). They have significant effects on soil chemical, physical, and biological properties and processes. Conversely, soil properties, climate, and agricultural practices affect earthworms (Figure 7). Soil physical and chemical limiting factors include organic matter content and […] More »

Assessment of Soil Health and Quality in the Agrosystems of WICST

Objective: Define the parameters of qualitative and quantitative soil quality and health indicator properties and provide baseline monitoring of soil quality and health for the WICST biodiversity project. Evaluate descriptive and analytical indicators of soil health and quality to compare continuous corn with other cropping systems in the WICST. Systems (and phases) that were evaluated […] More »

Descriptive and Analytical Characterization of Soil Health and Quality for the Wisconsin Integrated Cropping Systems Trial

The project objective was to track the effect on soil health and quality of a shift from continuous corn to other WICST cropping systems during the initial period of 3-5 years following the shift. Because of the conceptual newness and related sparsity of guidelines and methodology in the soil health and quality area, the project […] More »
