Abstract
Cover crops can benefit farmers by aiding in soil erosion control, increasing organic matter in the soil, and reducing nitrate losses into surface waters. Cover crops also have been promoted to alleviate soil compaction and improve soil drainage. Cover crops are an important practice in meeting Iowa’s nutrient reduction strategy goals. However, some research has indicated that planting corn or soybean following a cover crop or interseeding a cover crop can result in yield reductions. The objective of these trials is to evaluate yield potential for corn and soybean crops based on cover crop planting, timing, and species.
