Do Winter Cover Crop Seeding Rates and Soil Type Impact Soybean Production?

Integrating winter cover crops into an agricultural system is not new, but the potential for improved soil health and crop production have renewed producer interest over the past decade. According to a recent U.S. Department of Agriculture survey, cover crop acreage increased by 50% between 2012 and 2017 across the United States and includes expansion of acreage in the Mid-South. This has prompted university research to evaluate cover crops and soil conditions specific to that region. It has been well documented that winter covers can improve various soil properties. However, questions regarding their impact on crop yield still remain.
