Abstract

Cover crops can benefit farmers by aiding in erosion control, increasing organic matter in the soil, and reducing nitrate losses into the surface waters. Cover crops also have been promoted to alleviate soil compaction and improve soil drainage. Legume cover crops can supply nitrogen to the following crop. Cover crops are an important practice in meeting Iowa’s nutrient reduction strategy goals. However, some research has indicated that planting corn following a rye cover crop can result in corn grain yield losses, especially if the cover crop is not killed at least two weeks prior to planting the corn.
