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. Evaluation of Soil Test Phosphorus Extractants and Tissue Analysis for Corn in KansasPhosphorus (P) is a critical nutrient for corn (Zea mays L.) productivity. Determining an appropriate concentration of soil test phosphorus (STP) and P tissue concentrations is a fundamental step needed to make accurate phosphorus management decisions. The main objective of this study was to evaluate the relationship of four different STP methods (Mehlich 3, Bray 1, Bray 2, and H3A) for corn production and determine critical P tissue concentration at different growing stages. The study... G. Roa, D. Ruiz diaz |
3. Exploring Long-Term Phosphorus Management Strategies for Optimizing Crops Yields in KansasPhosphorus (P) is a crucial nutrient for sustaining crop productivity, yet its scarcity often challenges agricultural endeavors. Recognizing the essential role of P fertilization in maintaining agricultural productivity, this study takes a multi-year approach to P management. It specifically delves into the intricate dynamics of long-term P placement, evaluating its impact on crop yield under varying rates and combinations. The primary objective is to discern the most effective phosphorus fertilization... D. Ruiz diaz, G. Roa |
