There’s a need to clarify whether reducing N fertilizer is possible for farmers whose long-term soil health practice shave improved soil function. Farmers refer to a steep learning curve for reduced tillage and cover crop systems,

Side dressing in our part of the state is difficult because of terrain, limiting us to broadcasting urea. Ag Partners results on 74,000 acres over 6 years indicated a negative .05 bushel yield penalty for side dressing urea.

Our research has shown that 35% of annual nitrous oxide (N2O) emissions in Minnesota occur during the spring freeze-thaw period. Large nitrous oxide emissions from the freeze-thaw period have also been reported at numerous cold season locations globally,

The University of Minnesota conduct field studies across Minnesota to refine the economic optimum nitrogen (N)rate (EONR). These studies are combined into the Maximum Return to N (MRTN) calculator (http://cnrc.agron.iastate.edu/).

Agricultural nitrogen (N) inputs stimulate the production of nitrous oxide (N2O), a long-lived greenhouse gas with a global warming potential of 298 times higher than that of CO2.

Nitrogen (N) credits for corn production systems typically come from manure that was applied in the previous year or from alfalfa that was grown into the previous two years.
The Nitrogen Smart program was conceived by leadership at the Minnesota Corn Growers and the Minnesota Agricultural Water Resources Center and developed into a program by University of Minnesota Extension.
