Prior to 2007, University of Minnesota calibration and correlation data included in the new guidelines did not include any research sites north of Interstate 94. A request for funding from the Minnesota Corn Growers Association was granted in 2007-2009 to investigate corn Nitrogen response rates in NW and WC Minnesota relating to the new Corn Nitrogen Guidelines and validate the applicability of the N guidelines to this region of the state. Ten research sites were established in 2007 from Fergus Falls to Roseau, eight sites in 2008 from Fergus Falls to Warren and 6 sites in 2009 from Fergus Falls to Fosston to collect data to be included in the New N Guidelines and validate the applicability of the N guidelines to this region of the state.en-USPresentation
