1. Evaluating the Trade-offs of Cover Crops in Dryland Wheat Systems of the Colorado PlateauOn the semi-arid Colorado Plateau, dryland farmers are challenged by severely degraded soils and low and increasingly unreliable precipitation. Cover crops have been shown to improve soil fertility and mitigate soil erosion in many regions, but are also associated with use of limited soil moisture, a cost that could mean decreased cash crop productivity for farmers. Most literature on cover crops comes from relatively humid climates, where crop yield penalties due to cover crops may be less pronounced.... L. Eash, A. Berrada, K. Russell, S. Fonte |
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 |
