Drying and rewetting cycles substantially increase soil CO₂ release, study shows

The amount of carbon dioxide (CO2) released by microbial decomposition of soil organic carbon on a global scale is approximately five times greater than the amount of anthropogenic CO2 emissions. Thus, it is essential to clarify the impact of climate change on soil CO2 release dynamics.
