A statewide effort in Iowa to identify and map six types of conservation practices (terraces, ponds, grassed waterways, water and sediment control basins, contour strip cropping and contour buffer strips/prairie strips) has been completed. The effort will inform the Iowa Nutrient Reduction Strategy to help reduce sediment, nitrate, and phosphorus loads to Iowa streams. Iowa is the first state to analyze every watershed within its borders to create a detailed assessment of conservation practice implementation.
