Farmers - Get Nitrogen Smart!

By Brad Carlson
 
Farmers have been exploring new and creative ways to manage nitrogen fertilizer in recent years.  Remote sensing, crop growth models, in-season soil testing and variable rate application technology have all drawn significant interest for the potential to add profit, while reducing environmental impact.  Farmers have had to work diligently to determine the value of these technologies, all while keeping water quality issues in mind.  
 
Nitrogen Smart is a new educational program designed to provide the information necessary to evaluate nitrogen fertilizer options.  The program is being offered through a partnership between the University of Minnesota Extension, Minnesota Corn Growers, and Minnesota Agricultural Water Resource Center.  The three hour program will be offered in 8 locations around Minnesota starting on March 2.  Locations and times include:  March 2, Northwest Research and Outreach Center, Crookston, 9:00 AM, Big Wood Event Center, Fergus Falls, 6:30 PM; March 3, 1:00 PM, MinnWest Technology Campus, Willmar; March 4, 9:00 AM, Convention Center, St. Cloud; March 7, 1:00 PM, Southwest Research and Outreach Center, Lamberton; March 8, 9:00 AM, Southern Research and Outreach Center, Waseca; Maarch 11, 9:00 AM, Dakota County Extension Center, Farmington; and March 15, 9:00 AM, Heintz Center, Rochester.
 
Attendees will receive "Nitrogen Smart" designation, which will be good for three years.  There is no cost to attend due to generous support from the Minnesota Corn Growers.   Preregistration is not required, but is requested to speed up check-in at the meeting.
