To grasp the physico-chemical properties on the management groups of upland soil, the data obtained from the detailed soil survey which conducted from 1964 to 1979 by Agricultural sciences Institute, were analyzed and classified. The clay content in A horizon soil was low in sandy textured and well adapted types and high in heavy clayey type, and that in B horizon was lowest in volcanic ash type and highest in heavy clayey type. High organic matter content was found in the volcanic ash and plateau type. The correlations among soil physico-chemical properties were significant. Especially canon exchange capacity of B horizon soil was highly correlated with the content of available water, clay, silt and organic matter positively.
