Discussion related to the benefits of the integration of cover crops and improvement of soil health as part of crop management practices has increased over the past several years. A recent survey conducted by the Conservation Technology Information Center reported that 2012 harvested yields from corn fields following a cover crop were 9.6% greater than side-by-side fields with no cover crops, and soybean yields improved 11.6% following cover crops. Yield differences were even greater in regions most impacted by the 2012 drought, with corn yielding 11% greater and soybeans yielded 14.3% greater than those grown in fields with no cover crops.
