Summary

​What does it mean for a cotton producer to have healthy soils? How do you know that your soils are healthy? How do you develop and maintain healthy soils? These are just some of the questions this presentation will explore, as soil health can influence yield and production costs. For humans, plants, animals, and all ecological systems, bacteria and fungi have important roles in helping maintain our health and that of our soils by carrying out important functions. The soil microbiome, which consists of thousands of beneficial bacteria and fungi, is crucial for promoting plant growth, increasing soil carbon, maintaining nutrient availability, and building soil structure. We know that if we do not take care of our skin and gut microbiomes, we may not be in good health and may have more doctor bills. The same is true for any agricultural system: If producers do not take care of the soil microbiome, their soils will not be in good health and they will likely spend more money trying to produce crops. Finally, the presentation will provide a few examples of how to improve the soil health and maintain a strong soil microbiome.

About the Presenter

John ZakJohn Zak is Professor and Chair of the Department of Biological Sciences at Texas Tech University and Director of the Climate Science Center. He received his PhD in soil ecology from the University of Calgary, Alberta, Canada, where he worked as part of a team to develop approaches for revegetating highly disturbed soils. John’s lab at Texas Tech focuses on understanding the roles of the soil microbial community (bacteria and fungi) in natural and agricultural soils and how disturbances and climate variability determine the capacity of the soil microbial community to carry out the important processes of decomposition, soil carbon formation, and nitrogen mineralization. These studies are conducted from the Chihuahuan Desert in Big Bend National Park to the cotton production regions of the southern High Plains. This research is also part of a Citizen Science Cotton Producer Network that has been developed over the past 2 years to work directly with growers to help them understand how soil health and the soil microbiome can promote sustainable cotton production across the region.​
