| Outline of Final Research Achievements |
Understanding the biodegradability of soil organic matter (SOM) is a key to accurately predicting the response of soil C to global warming. In this study, we quantified the mineral-organic matter associations, the diversity of chemical structures and mean residence times of SOM, and the temperature sensitivity of SOM decomposition in Japanese forest surface soils by using SOM fractionation techniques, 14C analysis, 13C-NMR measurements, and soil incubation studies.
