The Impact of slope steepness and land use type on soil properties in Cirandu Sub-Sub Catchment, Citarum Watershed

摘要

The research was conducted to investigate the relationship between topography (slope steepness) and landuse on soil physical properties. This research was conducted at Cirandu sub-cathment, Citarik Catchment Area, Citarik Sub Watershed, Upper Citarum Watershed, West Java. The study was carried out using a physiographic free survey method, which is a survey based on land physiographic appearance, and soil sampling was carried out into transect on the similarity slope without calculating the point of observation range. Soil sampling was carried onto three classes of slope and three land use type The result of the research showed that there are no effect of slope steepness and landuse on organic matter, hydraulic conductivity and erodibility. The highest erodibility value was found on the forest with 8-15% slope.
