In Peninsular Malaysia, the basic unit for soil classification is soil series. Up to now more than 240 soil series have been identified. They are differentiated on the basis of their parent materials, major characteristics, landscape, and mode of formation. At the broadest level, they are divided into mineral or organic soils. Mineral soils are further subdivided as sedentary soils, reworked soils and alluvial soils. The organic soils are differentiated according to the nature of the organic material and its depth.
With regard to their distribution, the sedentary soils are found on undulating land to rolling and hilly terrain (34.2%) and on steep hills and mountains (37.4%). The reworked soils occur on intermediate and higher terraces and pediment (3.3%). The alluvial soils are found on low lying coastal and riverine floodplains (17.8%). The organic soils occur in lowlands, adjacent to the coast (6.0%). The remaining are disturbed urban and mining land (1.3%). Altogether there are twelve major soil subdivisions as shown in table below.
