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.

Soil incubation experiments revealed a comprehensive increase in CO2 release by drying-rewetting cycles (DWCs) among Japanese forests and pastureland soils, suggesting a significant contribution of the DWCs-induced destruction of microbial cells and reactive metal-organic matter complex to the CO2 release increase.

Drying and Rewetting Cycles Substantially Increased Soil CO2 Release

Niigata, Japan, has emerged as a critical region for understanding the dynamics of carbon dioxide (CO2) release from soil under changing climate conditions. Recent research conducted by a collaboration of scientists from Niigata University, Kyushu University, and the Japan Atomic Energy Agency has brought to light significant findings that could have substantial implications for global climate change models. The study systematically investigates…

Tokyo, Japan (SPX) Feb 06, 2025 
The global release of carbon dioxide (CO2) from microbial decomposition of soil organic carbon is estimated to be roughly five times greater than human-induced CO2 emissions. Given this substantial contribution to atmospheric carbon levels, understanding how climate change influences soil CO2 dynamics is critical.
