The morphological and physico-chemical properties of 11 soil series representing the major soil types in the Tasik Chini catchment in Pahang, Malaysia were studied. Soil types of the study area showed wide variations in their morphological and physico-chemical properties as a result of mean annual precipitation, soil parent material, vegetation and topography. Analyses showed that low values of silt were recorded in the horizon and the content of clay increased with soil depth. All the soil series contained low amounts of organic matter. Physical properties showed higher values for bulk density in the disturbed soils compared to the undisturbed forest soils. Regarding the chemical properties, these soils were strongly acidic. Electrical conductivity was also very low. Due to low pH, the contents of exchangeable base in all the soil types were very low. The cation exchange capacity of all the soil series were low with values less than 13.34 meq/100g soil.
