Abstract

Soil erodibility is defined as the ease with which the soil is broken down by the force of falling rainwater or the force of runoff. Soil erodibility value is determined by four factors, namely soil structure, soil texture, soil permeability and soil organic matter. The purpose of this study was to determine the effect of slope level on soil erodibility values and to determine differences in ultisol soil erodibility values on various slopes in plasma oil palm plantations (Elais guineensis Jacq.) Muara Harapan Village, Muara Enim District, Muara Enim Regency. South Sumatra. The research method used is a survey method at the level of detail and soil analysis is carried out in the laboratory. The research area is ± 10 Ha with a map scale of the research area 1:4000. Determination of sampling point is done using stratified random sampling method. The results showed that the erodibility of the soil at the study site was included in the medium category for each slope. The magnitude of the slope does not affect the increase in erodibility values. On gentle slopes (3-8%) it has an average erodibility value of 0.27, on slightly sloping slopes (8-15%) it has an average erodibility value of 0.28 and on sloping slopes (15- 30%) has an average erodibility value of 0.29. Soil erodibility is included in the moderate category so that land conservation measures still need to be carried out so that soil erodibility values can be reduced to low or very low by carrying out land conservation measures such as mechanical conservation measures by means of terracing and vegetatively by planting cover crops and adding organic matter on the plantation site.
