The data used in development of the North Dakota Corn Nitrogen Calculator was gathered with funding from the North Dakota Corn Council, the International Plant Nutrition Institute, and Pioneer Hi-Bred, Int. Data was gathered by Dr. Dave Franzen, lead investigator, with collaboration from Roger Ashley, Greg Endres, Jasper Teboh, Lakesh Sharma, Honggang Bu, Brad Schmidt and Eric C. Schultz. Dr. John Lamb, University of Minnesota, St. Paul, John Heard, Soil Fertility Specialist, Manitoba Agriculture, and Ron Gelderman, South Dakota State University also contributed recent N rate data used in the analysis.
The calculator website interface was programmed by Matt Franzen, 701-799-7443.
