1. Economic Model to Determine Optimum Nitrogen Rates for Small GrainsNitrogen (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 |
2. The Performance of the Soil Health Tool in Irrigated Calcareous Soils of the Western U.S.The Soil Health Tool (SHT), utilizes an integrated approach to soil testing for quantification of soil health and estimation of available nutrients for crop growth. The SHT is designed to mimic nature’s approach, as closely as possible, in order to estimate soil nutrient availability in the laboratory. The test itself includes extraction with water to measure soluble nutrients (C, N, P), a soil microbiological measurement, and a weak organic acid extraction to mimic additional nutrients... A.

3. Digital Tools to Improve Sustainable Agriculture PracticesVisualizations have been shown to promote learning and understanding and to aid in analysis and problem solving. Many concepts in agriculture are well suited to demonstrations that are used in classroom settings or part of training events. However, many demonstrations are difficult to seed in a large setting, or take more time than can be allotted. A series of demonstrations were either filmed or created in animation to provide a digital means by which trainers could more easily train their students,... R. Flynn, J. Walworth, J. Davenport, A. Ulery, D. Bloedel, J. Gleason |
