| Abstract: | To elucidate the influence of climate and vegetation upon the vertical distribution of soil moisture and its seasonal change is one of the fundamental problems in the studies on water economy of volcanic ash soils, that cover the larger parts of Japan, and have characteristic soil-water system.1) Few data are now available in this field, despite the fact that management of volcanic ash soils is practically one of the most urgent problems in Japan. |
