1. Nitrogen Management in Conservation Systems to Increase Use Efficiency and Cotton ProductionConservation management practices like no-tillage and cover crops have the potential to reduce wind erosion and stimulate ecosystem service, but lingering doubts regarding nutrient immobilization and water usage may limit their adoption on the Texas High Plains. A study was initiated at the Agricultural Complex for Advanced Research and Extension Systems (AG-CARES) in Lamesa, TX to examine the impact of supplemental nitrogen (N) fertilization on cotton yields and nitrogen use efficiency (NUE)...

2. Soil Health and Cotton Production in the Semi-arid Texas High PlainsSoil health has become a ubiquitous term in agriculture, but little is known about the impact of cropping system management on soil health metrics in semi-arid regions because of the majority of research has been conducted in humid or sub-humid regions of the United States. As a leading commodity of the semi-arid Southwest, cotton is an ideal candidate for soil health review. The purpose of this study was to assess a proposed set of soil health metrics in cotton production on the semi-arid Texas... J. Burke, K. Lewis, P. Delaune |
3. Subsurface Drip Fertigation Impacts on Nutrient Uptake and Partitioning in CottonSubsurface drip irrigation (SDI) is becoming a popular option for maximizing the water use efficiency of cotton (Gossypium hirsutum), especially in semi-arid environments of the Midsouth and Western United States. In the Texas High Plains where underground water resources from the Ogallala Aquifer are rapidly declining, there is increased adoption of water conservation technologies like center pivot and drip irrigation. In addition to increased water efficiency, drip irrigation allows... H.L. Valencia, J. Burke, T. Bennett, K. Lewis |
4. Developing Nitrogen and Phosphorus Fertigation Strategies in CottonSubsurface drip irrigation (SDI) is becoming a popular option for maximizing the water use efficiency of cotton (Gossypium hirsutum), especially in semi-arid environments of the Midsouth and Western United States. In the Texas High Plains where underground water resources from the Ogallala Aquifer are rapidly declining, there is increased adoption of water conservation technologies like center pivot and drip irrigation. In addition to increased water efficiency, drip irrigation allows... K. Lewis, H. Valencia, T. Roberts, J. Burke, G. Ritchie |
5. Sustainable and Resilient Cropping Systems to Mitigate Wind Erosion for the Enhancement of Human HealthIn the Texas High Plains, regenerative cropping practices in a predominantly conventional farming area can be used to prevent further depletion of topsoil by wind erosion. This loss of topsoil can cause a decrease in agricultural productivity and form dust storms that can be detrimental to human health causing a rise in hospitalizations of chronic lung damage, cardiovascular disorders, and diseases contracted by inhalation. Using regenerative farming practices, both the number and size of dust... K. Lewis, R. Babcock, J. Burke, C. Cobos |
6. Assessment of Microalgae Amendments on Soil Nutrient Dynamics and Cotton Productivity Under Limited Irrigation in Texas High PlainsTexas High Plains (THP) is a major cotton producing region of Texas. However, declining soil fertility and increasing risk of crop yield penalties associated with extreme weather patterns and low organic input have raised concern in sustainability of farmlands in this region. Micro-algae amendment is relatively new and emerging farm practice in crop production which is getting attention due to its ability to stimulate soil health and enhance crop productivity. There are no prior records on microalgae... A. Kafle, K. Lewis, J. Burke, H. Nakabuye, M. Jonhson |
7. Evaluating the Profitability of Nitrogen Management Strategies to Increase Yield in Regenerative Cotton Production SystemsSoil health management practices, such as cover crops and no-till systems, are common in semi-arid cropping systems to reduce wind erosion. However, implementing these practices can also lower cotton yield. As a result, cotton production using no-till and cover crop systems in semi-arid environments tends to be less profitable than conventional systems, despite lower costs from fewer tillage operations during the growing season. For these soil health practices to be economically sustainable in... A. Wright, J. Burke, K. Lewis, W. Keeling, W. Keeling |
8. Nutrient Uptake Variability of Modern Cotton CultivarsCotton (Gossypium hirsutum) is one of the most economically important crops in Texas, generating more than $3B in annual revenue. Since the development of transgenic cotton cultivars in the early 2000s, cotton yield potential has increased. Despite these advances, little is known about the nutrient uptake and partitioning patterns of these different cultivars. The purpose of this study was to evaluate the nutrient uptake and partitioning patterns of five modern cotton cultivars grown under three... J. Burke, K. Lewis |
