Cover Crop Nutrient Cycling & Other Soil Health Benefits on South Dakota Croplands with Anthony Bly

Cover crop studies across South Dakota showed reduced soil nitrate and improved microbial activity, nitrogen mineralization, and soil health indicators. Benefits varied with precipitation, with occasional reduced corn yields in dry years. Overall, cover crops consistently outperformed no‑cover controls, enhancing nutrient cycling and agroecosystem resilience. Anthony Bly is a SDSU Extension Soils Field Specialist.
