Abstract
The study was conducted to determine the variability of soils along the southern slope of Mt. Banahaw, Quezon, Philippines. Three landscape positions were identified along the southern slope: convex creep slope, transportational midslope and colluvial footslope. Five pedons were selected and sampled along the transect. Morphological characteristics were examined in situ, while physical and chemical properties were measured at the laboratory. Soil depth and clay fraction was highest at the transporational midslope (Pedons 2 and 3). Soils at the convex creep slope (Pedon 1) and colluvial footslope (Pedons 4 and 5), showed darker soil color which can be attributed to high levels of organic matter in these landscape positions. Increasing silt fraction was observed downslope. CEC and percent base saturation was lowest at the transportational midslope. Soils were classified as Inceptisols and Alfisols. Slight erosion risk was obtained in Pedons 1 and 4, while moderate erosion risk was obtained in Pedons 2, 3 and 5. Aside from landscape position, inherent soil properties and land use affects the susceptibility of the soils to erosion. Proper management practices should be applied on sites that are moderately to highly susceptible to erosion to minimize soil loss.
