| Outline of Final Research Achievements |
I investigated the decomposition rate of soil organic carbon (SOC) controlled by cellulose supply (priming effect) among three different soil types to clarify the soil carbon dynamics with some impact to soil. Then, I revealed two important points on decomposition rate of SOC controlled by cellulose supply among three soil types. First, the decomposition rates of SOC with priming effect among three different soil types and/or their depths are diverse. Second, Amount of carbon of light-density fraction and middle-density fraction are more important factor controlling decomposition rates of SOC with priming effect among three soil types.
