This project will accelerate production of County Geologic Atlases (part A). An atlas is a set of geologic maps and associated databases for a county that facilitate informed management of natural resources, especially water and minerals.
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 Farm in Westport, Minnesota to provide a better understanding of nitrogen fertilizer management and the associated water quality impacts on irrigated, sandy soils.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
