Outline of Final Research Achievements

Based on soil samplings before and after the events of forest degradation in Central Cambodia, we assessed the decomposition rate of soil organic matter and pointed out its controlling factors in this region. We also reviewed the published and unpublished data on soil organic carbon in Cambodia to create a new dataset on soil carbon stock and a technical report for public release. We used this dataset to develop a model for estimating soil carbon stock and the potential amount of decomposition of soil organic carbon after forest degradation in the national level.
