Uncovering the Role of Microbes in Soil

A single teaspoon of soil contains a staggering number of microbes—often billions of individual cells—including up to 1 billion bacteria. Researchers in the University of Maryland Center of Excellence in Microbiome Sciences are exploring how this diverse microbial community can affect agricultural output, our environment, and human and animal health. Stephanie Yarwood, co-director of the center, explains in this video how research focused on wetland restoration and agricultural management can impact microbial communities—and what implications those changes can have to nitrogen cycling, greenhouse gas emissions, and carbon storage. Yarwood is a professor of environmental science and technology at the University of Maryland's College of Agriculture and Natural Resources.
