Twelve soil samples were collected from Southwestern Hokkaido (including the Oshima peninsula); five samples were used for the present investigation, viz., Yu-no-tai, Imagane, Kuromatsunai, Ginzan and Maruyama soils. (Fig. 1) The size distribution, the amounts and properties of soil humus and the amounts of colloidal matter after TAMM'S method were determind respectively, as well as the inorganic components, acidities and base-exchange capacities. According to the data thus obtained, the authors concluded that the soils of Yu-no-tai, Kuromatsunai and Maruyama belong to Brown-forest soil. Imagane and Ginzan soils apparently are podzolic in their characters. But judging from the ultimate pH value of these last two soils it will be reasonable to understand that these two soils are in the process of regeneration from Podzolic soil to Brown-forest type. The authors published a soil map of Hokkaido based upon studies, made up the present. (Fig. 4 of this report Part 5).
