| Outline of Final Research Achievements |
We tried to understand nitrogen (N) retention of forest soils, focusing on N in mineral associated organic matter (MAOM). In the experiment, we also tried to consider the topographic variations in soil N transformations. In the examined two forest stands, the results of N-15 addition incubation suggested that N over fine mineral particles (silt and clay) did not related to N retention, and that lower C/N ratio of MAOM indicated lower N retention. Further research in many forest types is needed for generalization.
