The soil condition of several types of Alnus japonica stands, and neighboring Ulmus davidiana var. japonica stands were studied in a small tributary basin in Miyagi Prefecture, Japan. The soil type of the study area varied from anaerobic peat soil in poorly drained areas on back swamps to aerobic alluvial soil in well drained areas. Differences in soil properties among the stands were clear in the top soils. Anaerobic soils with high clay and high organic matter contents and high CEC value were occupied by A.japonica-Polygonum thunbergii stands. A. japonica-Ilex crenatd var. paludosa stand on peat soil showed also high values for these properties. A. japonica-Filipendula kamtschatica stands and U. davidiana var, japonica stands were characterized by well drained soil which was low in organic content and contained much coarse sand. These stands were similar in such properties, but soils of A. japonica-Filipendula kamtschatica stands were lower in degree of base saturations, more acidic and more anaerobic than those of U.davidiana var. japonica stands.
