1. Kernza in Wyoming: Evaluating Perennial Grains to Revitalize Wyoming Dryland AgricultureKernza, a perennial grain crop harvested from intermediate wheatgrass, has the potential to provide a sustainable alternative to wheat-fallow agriculture that can build soil health. Kernza had not yet been planted in Wyoming, where the drier climate presents unique challenges yet stands to particularly benefit from the adoption of a perennial crop. From spring 2021-2024, Kernza will be grown on five farms across southeast Wyoming under a variety of management strategies. We aim to determine Kernza’s... H. Rodgers, J.B. Norton, L.T. Van diepen |
2. Managing High-pH Soils: Restoring Nutrient Function with Polysulphate and Acidic Phosphate FertilizersHigh soil pH often reflects the active consumption of hydrogen ions (H⁺) by carbonates and bicarbonates, which suppresses calcium solubility and reduces the availability of phosphorus, potassium, and key micronutrients. These limitations are driven by soil chemistry rather than true nutrient deficiency, restricting nutrient mobility and root access. This presentation will examine Polysulphate® as a functional calcium and sulfate source that improves system efficiency. In addition, ICL... A. Foster, J. Hagele, T. Donoho, D. Tollefson |
