Lim and water conservation technologies by farmers is one of the major causes that have resulted in accelerated soil e this context, signifcant attention has been given to soil and water conservation practices. Tis study was conducted the efects of soil and water conservation practices on soil physicochemical properties after being practiced continu 10 years. Te physicochemical properties of soil of landscape with physical soil and water conservation stru biological conservation measures and physical soil and water conservation structures combined with biologica measures were compared with soil of landscape without soil and water conservation practices. Te result of analysi soil and water conservation interventions (both with biological and without biological measures) signifcantly inc pH, soil organic carbon, total nitrogen, and available phosphorus content than the soil of landscape without conservation practices. Te results of the analysis also showed that the mean value of cation exchange capacity and bases (K + , Na + , Ca + 2 , and Mg + 2) of the soil under nonconserved farm feld was signifcantly lower as compared to the soil of adequately managed farm felds. Te fndings of this study clarifed that there was signifcant variation in soil properties. Tis variation could be due to uneven transport of soil particles by runof. Terefore, soil conservation structures supported with biological measures improves the soil's physicochemical properties.

However, the extent of variability has not been explored in the study area. This study has, therefore, been initiated to assess the spatial variability of soil organic carbon stock in Gurje subwatershed Hadiya Zone, Southern Ethiopia. A total of 40 randomly predefined sampling points were identified for soil sampling using GIS and a total of 80 composite soil samples and 80 core samples were collected from those points at two sampling soil depths (0–20 cm and 20–40 cm). The ordinary kriging (OK) method was used as a geostatistical tool and applied to model the spatial variability of soil organic carbon in this study. With respect to soil depth, the coefficient of variation (CV%) for SOC and SOCS varied from 40.87 to 51.36%, which indicated moderate variability in the study area. For the land use types, the CV% varied from 7.94 to 42.06%, indicating low to moderate variabili...
