The purpose of this project for the past year has been to research how corn will perform without the use of commercial fertilizer. This is being pursued in order to help American farmers realize that past legume credits and past and current manure credits can be enough nutrients, especially nitrogen, to support a corn crop throughout a growing season. This approach is also expected to produce no difference in the harvested yield. The project also consisted of researching and comparing the new and old nutrient management recommendations prepared by the University of Minnesota. Throughout the growing season, various scouting procedures and tests were conducted to help test our hypothesis. Replicated test plot areas were set up to help compare and contrast yield calculations in the fall. Analysis of the resultant data are on-going.
