Cover Crop Cost-Share Programs in Iowa: Do They Work?

Author

Abstract

Farmers often use cover crops for their soil health benefits. However, the benefits of cover crops go beyond the farm, as they have been shown to reduce nutrient pollution from fields to waterways through leaching or runoff. As such, cover crops have been extensively promoted as a way to improve Iowa's water quality. However, as of 2017, cover crops were used on only 4% of Iowa cropland.
