The sandy soils of Muscatine County, Iowa, are prone to erosion and leaching. In the fall, leftover fertilizer applied to the corn and soybean crop is highly susceptible to leaching. Cover crops have been widely acclaimed to mitigate such issues as they prevent erosion and scavenge residual nitrogen. Although these attributes are widely known, adoption of cover crops has been slow. Information on cover crop planting dates, performance, and advantages are available, but few data are available that is applicable to Iowa soils and growing conditions.
