Warming Climate and Elevated Ozone Affect Soil Carbon Sequestration

A study from North Carolina State University, published in Science Advances, showed that increased climate warming and elevated ozone levels appear to have detrimental effects on soybean plant roots, their relationship with symbiotic microorganisms in the soil, and the ways the plants sequester carbon. In testing, warming and increased ozone levels made soybean roots thinner and weaker. In turn, these weaker roots caused a reduction in and a change in the type of arbuscular mycorrhizal fungi (AMF). AMF play a role in carbon sequestration by preventing the decomposition of soil organic matter.
