Nitrogen Recalibration for Corn in North Dakota

The nitrogen (N) recommendations for corn in North Dakota (ND) need to be updated using actual field results from ND. Existing recommendations are based on Minnesota data, and older ND field calibration data. There have been many changes in cropping systems especially conservation tillage adoption, weed control, and corn hybrid genetics. Many of the newer hybrids are more resistant to water limiting conditions experienced in parts of ND. The study will consist of N response research experiments at a number (8 to 10) of sites depending on resources and locating suitable field research sites. This study will be conducted for two years to generate data for up to 20 site-years of research results.
