Complex geologic composition and hilly topography occupy most of the Southern Mountain physiography of Java, especially in the southern area of West Java. It seems that the soils associated with this environment are mostly controlled by parent material and topography more than the other soil forming factors. Eight pedons, five from the Cisampora Estate and the rest from the Sumberagung Estate, were sampled to determine the effect of those two factors on fertility of the soils. Based on the macromorphological data, most of the soils studied met the criteria for Latosol of the 1961 Soepraptohardjo's classification system, although some evidence was still present indicating its development from Andosol. In contrast, using selected physico-chemical properties and the presence of genetic horizon, most of the soils belong to Utisol. Order of each soil type is more likely dependent upon topography and parent material for those in the Cisampora and Sumberagung Estates, respectively.
