Source of Additional Funds

Material cost for monitoring wells paid for by the Minnesota Department of Natural Resources (DNR). The DNR also paid for the monitoring equipment in the wells.

Project Overview

 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.

About the Issue

The N Rate Study was done under irrigation because Minnesota has over 300,000 acres of irrigated corn, and the U of M’s nitrogen BMPs rates for irrigated corn will apply widely across Minnesota’s Central Sands.  The study examined seven nitrogen rates for irrigated corn and five rates for dryland corn.  Each rate was tested in a 10 x 60-foot plot and replicated four times each growing season.  In addition to yield data, the U of M looked at nitrogen use and fate by examining soil test results from each plot before, during and after the growing season.
