Technical Abstract: The establishment of organic no-tillage systems in the upper Midwest has been hindered by the difficulty in controlling weeds. Residue from the rolling and crimping of winter-cover crops as a weed control component has been explored in a cross-site comparison across the upper Midwest. We hypothesized that no-tillage and cover crop residue inputs would improve soil quality in these organic systems. We observed increases in soil microbial biomass carbon with implementation of no-tillage in the majority of the six cross-site locations tested. Differences in microbial community structure using fatty-acid methyl ester profiles were also evaluated.
