Abstract
Abstract Characteristics of brown forest soils under beech and/or coniferous forests in northern Kyoto were examined from the viewpoint of the andic soil properties in comparison with podzolic soils in the same area to analyze the pedogenetic processes of brown forest soils in Japan. The brown forest soils in the present study were characterized by two pedogenetic processes: Al translocation caused by organic matter, and Fe-organic matter complexation in the surface horizons. In taking account of these pedogenetic processes, the brown forest soils in the present study could be differentiated from Andisols, red- and/or yellow-colored soils, and podzolic soils based on the values of the Alp/Alo ratios, and distribution pattern of free Al; activity of free oxides; and distribution pattern of Feo, Fed, and Fet in the profile, respectively.
