The Minnesota County Geologic Atlas program is an ongoing effort begun in 1982 that is being conducted jointly by the University of Minnesota's Minnesota Geological Survey and the Minnesota Department of Natural Resources (DNR). The program collects information on the geology of Minnesota to create maps and reports depicting the characteristics and pollution sensitivity of Minnesota's ground-water resources.
The Discovery Farms program is a farmer-led effort to gather field-scale water quality information on different types of farms across Minnesota. The three pillars of the program are farmer leadership, credible research, and communicating results.
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 Minnesota Department of Agriculture (MDA) is working with partners at the Rosholt Research Farm in Westport, Minnesota to develop guidance and provide education on irrigation and nitrogen best management practices and the associated water quality impacts on irrigated, sandy soils.
