Degraded bare land, Rehabilitated degraded bare land, Natural grass land, Soil properties, Soil organic carbon stock

The aim of the study was to determine selected soil physicochemical properties of degraded bare land, rehabilitated degraded bare land and natural grassland and make comparisons among the soil properties; and estimate soil carbon stock of the land use types. Standard procedures were employed for the analyses of soil parameters. The soil organic carbon stock was estimated from the bulk density of 0-5 cm soil depth. One way ANOVA was employed to compare the soil parameters at particular soil depth. The rehabilitation of degraded bare land had influenced most of the soil properties at 0-10 cm soil depth. The soil moisture content of the rehabilitated degraded bare land had increased when compared with the degraded bare land. The bulk density of the rehabilitated degraded bare land soil was significantly lower (1.21 ± 0.04 g/cm3) than the degraded bare land soil (1.31 ± 0.02 g/cm3). The OM, TN, pH, CEC, Ex. Ca and soil organic carbon stock of the rehabilitated degraded bare land soil were improved when compared with degraded bare land soil. Av. P content and Ex. K of the rehabilitated degraded bare land soils were lower at 0-10 cm when compared with the degraded bare land. The soil organic carbon stock of natural grassland > rehabilitated degraded bare land > degraded bare land. Most of the soil chemical properties of the rehabilitated degraded bare land under study are still very low to medium except Ex. K.
