1. Cover Crop Function and Management Optimization for Semiarid West Texas Cropping SystemsWater-use is a primary concern preventing integration of cover crops in dry climates. Recent research has demonstrated that adequate cover crop residue (with optimal termination timing) is more likely to improve soil water dynamics for the subsequent crop. Regarding cover crop function in West Texas, wheat stubbles as a fallow may offer a cheap and effective solution to prevent wind erosion and facilitate water storage in soil profile. Optimum management practices are likely different though... T. Hussain, R. Noland, R. Matschek, . Delaune, E. Kimura , J. Muir |
2. Monitoring Nitrogen Transformations and Their Interaction with Potassium Uptake in Cotton Production SystemsUnderstanding the temporal dynamics of soil nitrogen (N) is critical for optimizing nutrient management in cotton production. This research monitored soil N transformations, specifically ammonium (NH₄⁺) and nitrate (NO₃⁻), throughout the cotton growing season. An additional focus was also placed on interactions between soil N forms and the uptake of essential plant nutrients, particularly potassium (K). Soil samples were collected at multiple depths and time points across different management... J. Derrick, B. Arnall, N. Mathey, B. oliveira liberato, C. Camacho |
3. Evaluating Side-Dress N Application Method in SorghumGrain sorghum (Sorghum bicolor L.) is a resilient cereal crop widely grown across the Great Plains, where nitrogen (N) management decisions are often constrained by equipment availability and application timing. While in-season N applications may improve flexibility for producers, concerns remain regarding potential leaf injury (“nitrogen burn”) from high-rate applications. This study evaluated the effects of N source and application... B. Arnall, C. Camacho |
