Deep Soils Have Dual Role In Global Carbon Cycle, New Study Shows

Soils, especially those one meter down and deeper, play a critical role in the global carbon cycle and are estimated to hold more than three times the amount of carbon as the atmosphere, say an international research team including Dr. Malak Tfaily, UArizona Environmental Sciences assistant professor and BIO5 member. The team reports on how their new model is designed to predict how deep soil carbon responds to environmental changes.
