Advanced Nitrogen Smart

University of Minnesota/Brad Carlson

The Nitrogen Smart program has been a success with documented outcomes showing reductions in unnecessary N fertilizer applications and increased profits due to changes in application practices. The program offers “certification,” although it has no legal status. This certification is good for three years. The program is now poised to enter its third year in 2018, meaning 2019 will see the first group of attendees needing to recertify.

Climate Change Impacts on Minnesota Corn Production and Environmental Consequences

University of Minnesota/Tim Griffis

With past support from the Minnesota Corn Research and Promotion Council, we have significantly advanced the development of the University of Minnesota Mesocosm Facility (http://biometeorology. This facility is now allowing us to probe how climate and management decisions impact corn productivity and some of the critical environmental side effects of food production.

As of November 2, 2015, 7 of 12 mesocosms are fully functional and being used in trials. The other 5 mesocosms are being brought online following operational testing and are expected to be used in trials before the end of December 2015.
