Led by Iowa Department of Agriculture and Land Stewardship and CleanWaterIowa, we are joining the celebration of Cover Crop Week.
Cover crops are a great way to improve soil health and protect water quality. Many Iowa farmers are adding cover crops to their crop rotations so soil stays covered when the fields are not growing other crops. Cover crops also improve soil organic matter and slow water runoff.
The Iowa Nutrient Reduction Strategy research summary indicated an average 31% reduction in nitrate (N) concentration with use of a rye cover crop and a 28% reduction with an oat cover crop. The living cover crop will reduce soil erosion and phosphate (P) loss by about 29%, when planted in late summer or early fall.
