Abstract


The open pit minning process has an impact on soil properties, including the soil physical properties. The physical properties of soil in the rehabilitation area will develops over time. This study purpose was to determine the soil physical properties development in the 20 years old rehabilitation area and compare it with the forest area. Soil samples test was carried out in the laboratory, data analysis refers to the criteria for assessing the soil physical properties. Based on the soil profiles observations it is known that the rehabilitation area has 3 horizon, horizon boundaries are clear; 72 cm root depth; soil consistency and soil structure varies, soil texture is the silty clay loam. Theforest area has 6 horizon, horizon boundaries are diffuse, 117 cm roots depth; soil consistency is predominantly firm (moist conditions) and sticky to very sticky (wet conditions); soil structures is sub-angular bocky and angular blocky, soil texture is sandy loam. The value of soil permeability, soil porosity and bulk density are in the same class, namely a rather slow permeability, a low bulk density and a very high porosity.
