Climate change and environmental degradation are increasingly threatening our ability to feed a burgeoning human population. Switching to agricultural practices that support beneficial soil microbes, and thus healthy soils, may help farmers achieve the yields required for continued food security. Dr Zachary Senwo from the College of Agriculture, Life and Natural Sciences at Alabama A&M University has spent over two decades exploring how agricultural management practices impact soil health. In an extensive new project, his team is investigating soil nitrogen cycling and the role of microbes in soil health.
