1. Changes in Soil Quality During the Transition from Irrigated to Dryland Cropping SystemsThe availability of irrigation water enhances crop productivity and, in turn, increases crop residue inputs and soil quality. With increased pressure on declining groundwater resources, some formerly irrigated lands are being transitioned to dryland management. However, little is known about the shifts in soil quality after conversion from irrigated to dryland cropping systems. The objective of this work was to quantify the effect of irrigation retirement on the early changes in soil quality.... A. Nunez, R. Ball, M. Schipanski |
2. Nitrogen Management in Semi-arid Conservation Cotton Production SystemsThe Southern High Plains (SHP) region of Texas is one of the largest cotton-producing regions in the United States. Cotton production is hindered by climatic conditions and wind erosion, but attempts have been made to adopt conservation management practices like cover crops and crop rotations to limit these effects. Conservation management practices can reduce a soil’s susceptibility to wind erosion, but their adoption has been limited on the SHP due to producers’ concerns regarding... J. Burke, K. Lewis, W.

3. 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 |
