| Research Abstract |
Vermiculite, which controls cation exchangeable reactions in soils, formed from thermodynamically unstable mica minerals under humid climatic conditions in Japan. The amount of vermiculite is large in the following order of parent materials; sedimentary rock (i.e. shall) > acidic rocks > basic rocks, volcanic ash. Active aluminum and iron contents were high in high altitude soils, besides extremely high amounts in volcanic soils. They contributed to organic matter accumulation, maintained soil pH with dissolving, and controlled sorption capacity and intensity of phosphate.
