| Research Abstract |
The purpose of this research was to make clear transport phenomena of materials through vadose zones, which are still vague mainly because of the lack of knowledge in missing sinks and missing sources of them. We succeeded in obtaining new findings :(1) salt accumulations due to fluctuations of relatively shallow groundwater levels,(2) excess CO_2 emission from soils to the atmosphere due to infiltration of rain water,(3) irregular CO_2 emission from soils to the atmosphere due to the priming effects after application of organic matters,(4) unique accumulation of carbon inside the soils under forest fire events, and(5) missing sources and missing sinks in vadose zones under possible climate changes.
