Farmers on a quest to keep more fertilizer on their fields—and out of Iowa’s waterways—may have an easier time finding a solution, thanks to new research from the Iowa Geological Survey, housed at the University of Iowa College of Engineering's IIHR-Hydroscience & Engineering. They have created a comprehensive nutrient runoff mitigation guide for farmland in both the Ohio and Upper Mississippi River Basins. The goal of the guide is to reduce the overabundance of choice farmers can face in approaching nitrate and phosphate nutrient reduction. Farmers can identify their soil type, land slope, crops grown, and nutrients used, and the researchers’ guide can deliver them a best-practice solution for optimal run-off mitigation.
