Abstract

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