​​The use of cover crops is constantly making headlines and being featured in agricultural news outlets. But will planting cover crops work in your region, especially if it is a semi-arid environment? Exploring how to begin with cover crops can be overwhelming, as a lot of information is available from very diverse climates. This presentation outlines a few simple strategies to consider to successfully implement cover crops in semi-arid cotton systems.​

Paul DeLaunePaul DeLaune is an Associate Professor and Environmental Soil Scientist at Texas A&M AgriLife Research in Vernon, Texas. He obtained his MS and PhD in Agronomy/Soil Science at the University of Arkansas and his BS in Agronomy from Oklahoma State Un​iversity. Since joining Texas A&M AgriLife Research in 2007, Dr. DeLaune has focused on protecting water resources while maintaining agricultural production goals. Research topics include evaluating tillage and water management strategies in various cropping systems to improve nutrient and water use efficiencies, crop yields, soil health, and subsequent groundwater and surface water quality. Additionally, Dr. DeLaune has focused on the impact and adaptability of various cool-season and warm-season cover crop monospecies and mixtures on stored soil moisture and nutrient cycling in semi-arid cropping systems. He enjoys working directly with producers to learn of current issues first hand and develop applied research programs to meet critical needs.​​
