The morphology and physicochemical properties of soils under four different forest types, i.e., dry evergreen forest (DEF), dry deciduous forest (DDF), mixed evergreen-deciduous forest (MF), and swamp forest (SWF), on the west bank of the Mekong River in Cambodia were studied to clarify the variation in and characteristics of tropical seasonal forest soils. The soils in the study area were generally sandy, compact, and nutrient-poor. The forest types clearly differed in clay and carbon content. The clay content was higher in DEF than in MF and DDF at depths of 0-200 cm. The total carbon content in the upper horizons was higher in MF than in the other forest types, except SWF. These differences indicate the relative intensity of ferralization and podzolization in the soils. The grouping of soils based on the U.S. Soil Taxonomy was similar to that based on the World Reference Base (WRB) and agreed with the grouping of forest types. In the WRB system with qualifier levels, two DEF soils were classified as Haplic Acrisols (Alumic, Profondic) and Vetic Acrisols (Alumic, Profondic). Also, two NW and DDF soils were classified as Albic Podzols and Ferralic Arenosols (Dystric), and Haplic Acrisols (Albic, Alumic, Profondic, Arenic), respectively. SWF soil was classified as Haplic Umbrisols (Humic, Laxic, Clayic).
