The Nitrogen Rate Study on Coarse-Textured Soil (N Rate Study) was done in 2015-2018 by the University of Minnesota (U of M) and Central Lakes College (CLC) at CLC’s farm in Staples, MN. The study examined nitrogen fertilizer rates for corn on sandy soil—with and without irrigation. The study specifically considered potential nitrogen loss from dryland corn versus irrigated corn and was established after the U of M released new nitrogen rate guidelines in early 2015.
The Root River Field to Stream Partnership is a collaborative effort led by the Minnesota Department of Agriculture in partnership with Fillmore, Mower, and the Root River Soil and Water Conservation Districts, local farmers, crop advisers, the Minnesota Agricultural Water Resource Center, and the Nature Conservancy. Together, project partners are addressing the following key questions:
The Minnesota Department of Agriculture (MDA) has designed a Township Testing Program to determine current nitrate-nitrogen concentrations in private wells on a township scale. The MDA has identified townships throughout the state that are vulnerable to groundwater contamination (because of local geology or shallow groundwater) and have significant row crop production. These are the counties that will be prioritized for Township Testing.
