Symbiotic arbuscular mycorrhizal fungi found to play the dual role of carbon sequestration and decomposition in soil [Registered]

In a surprising finding, North Carolina State University researchers have shown that certain soil microbes thought to promote chemical interactions that make the soil a carbon sink actually play a more complex, dual role when atmospheric carbon levels rise. In a paper published in the Aug. 31 edition of Science, North Carolina State University researchers show that important and common soil microscopic organisms, arbuscular mycorrhizal fungi (AMF), play a role in sequestering carbon below ground, trapping it from escaping into the atmosphere as a greenhouse gas. Yet at the same time, the study shows, elevated levels of atmospheric carbon dioxide…
