1. Economic Model to Determine Optimum Nitrogen Rates for Small Grains Nitrogen (N) fertilizer is generally the highest input cost for Montana grain growers; therefore, it has become imperative that a tool be developed to assist crop advisers and farmers in determining economically optimum N rates (EONR). Data from all available MSU-conducted N fertility trials were gathered for spring wheat, winter wheat, and barley. Only the data sets for dryland fields following fallow were deemed large enough to have confidence in any resulting models, and all other data were... C. Jones, D. Griffith, G. Jackson Download paper
2. ManureDB: Creating a Nationwide Manure Test Database Manure nutrients serve an important role in crop production, however compared with commercial fertilizers there is a lack of standardized information. When exact manure values are not known, manure book values have been referenced. Recent data from midwestern United States (US) labs indicates manure nutrient levels have changed from book values published by Midwest Plan Service (2004) and American Society of Agricultural and Biological Engineers (2005). Manure laboratory analysis has improved... N.L. Bohl bormann, M.L. Wilson, E.L. Cortus, K. Janni, K. Silverstein, L. Gunderson Download paper
