Outline of Final Research Achievements

Soil formation rate was estimated in forest watersheds at Mt. Kasuga, Yata Hill and Mt. Ohe which have different parent rocks using the watershed-based mass-balance method. In addition, we could examine the accuracy of this methodology to estimate SFR through the reanalysis of the available data base, although we did not have a plan to do that at the beginning of the project. This allowed us to realize the importance of the analysis of the long-term mass balance data recorded at a long-term ecological monitoring site in Hubbard Brook (USA). So, we could obtain the relevant data but its analysis is still on-going. As a result, although we could only partially confirmed the reliability and applicability of the watershed-based mass balance method to estimate the soil formation rate. We are expecting that these findings will give new insights to the future study.
