| Research Abstract |
Andic properties and those spatial variability of Fulvic Andosols-related soils on the Ohira Hill in central Miyagi Prefecture and the Toshima Terrace in central Akita Prefecture were examined. In the most of slope positions on the studied areas, andic properties depended on the active aluminum, while strong contribution of active iron was confirmed in the foot slope due to the specific soil moisture condition. Soils on foot terrace and side slope classified Andic Brown Forest soils and Haplic Brown Forest soils, respectively, although those on foot slope classified Aquic Brown Forest soils. Relationship between slope position and andic properties shows an important finding about the spatial distribution of Fulvic Andosols-related soils in hilly areas.
