| Outline of Final Research Achievements |
In soils, phosphorus and carbon are most important elements in terms of agriculture and environments: highly mobile phosphorus is available for plants while it may flow into and pollute water system; stabilization organic carbon in soils is beneficial both for soil fertility and mitigation of climate change. Mobility of phosphorus and stability of organic carbon are controlled by surface properties of soils as well as composition of soil secondary minerals. In this study, I revealed 1) the effects of soil forming factors on soil secondary mineral composition in various soils, 2) retarding effect of soil micropores on phosphorus mobility, and 3) the effects of surface hydroxides and micropores of soil particles on organic carbon stabilization.
