This project had two separate but related on-farm research projects conducted on farm fields in northwest MN from 2017 to 2019. Both trials were conducted in wheat, one project was a variable rate nitrogen (VRN) and the other was a supplemental sulfur trial. A critical component of this field research was to develop a network of farmer cooperators and crop consultants willing to partner and collect field level agricultural research. In the three years of this project, the level of cooperation and partnership exceeded initial expectations. Further, these two projects have served as a springboard to increase the scope of agricultural research generated with full field level variability and experimental methods designed which allow commercial agricultural equipment to be used in all aspects of these field trials.
