- Abstract
The research purposes were to analyze land use’s effect on soil physical properties and measure several lands’ soil quality index in the Bulili plateau. Its conducted on three types of land use consisted of a mixed plantation, maize plantation, and forest. Soil sampling at each type of land use was carried out at five different points so that in total, there were 15 locations for soil sampling. Soil samples were taken at a depth of 0-30 cm after removing the organic layer on the soil surface. Observation of soil physical properties, including clay content, bulk density, total porosity, saturated hydraulic conductivity, organic carbon, aggregate stability, and available soil water capacity, were used to design soil quality index models. Root depth was also observed. The results showed a significant effect of land-use change on all observed soil physical properties parameters. The soil quality index for mixed plantation, maize plantation, and forest belonged to the criteria of good (0.6474), quite poor (0.3486), and good (0.6590), respectively. Land-use change caused the soil’s function to conserve biological activities to decline higher than the functions of soil water redistribution and filter - buffer.
