Interpretive Summary:

Technical Abstract: A large scale systems study on conventional and organic management systems was established. Two vs. four year crop rotations (corn-soybean, corn-soybean-wheat-alfalfa), inorganic vs. organic fertilizer sources, and conventional vs. strip tillage management practices were compared. Fatty acid methyl esters (FAME) were extracted from the top 10 cm of soil in spring samples collected over three years from initial plot establishment. FAME profiles were compared by principle component analysis to determine if management practices affected the microbial community.
