Reviewing the effect of toposequence on soil properties are essential for addressing the proper land use and land management. In view of this, it was conducted to review the effect of different topographic position and slope level on the selected physicochemical properties of soils. Four different slope level, such as upper slop, middle slope, foot slope, and lower slope were considered. Not only the slope level direction of the slope faces important when slope is > than 10 %.Noticeable in South east mountain. North Slope colder soils, less evaporation, more leaching thus more soil development, whereas South Slope warmer soils, more evaporation, less leaching thus less soil development. The results of the review, shows that cation exchange capacity, soil organic matter, soil Organic carbon content, total nitrogen, copper, total porosity, bulk density, infiltration rate of the shoulder slope level was lower than the upper slope level and the middle slope. In the other case, soil reaction, cation exchange capacity, Micronutrient, total nitrogen, and available phosphorous is high depend on organic carbon, organic matter, and the clay particle. Bulk density, total porosity, infiltration, and hydraulic conductivity depend on soil particle distribution. This review finally, concluded that the soil properties were maintained relatively under upper slope, and back slope, whereas under the shoulder due to steepness of the slope, and under the foot slope due to the deposition of materials from upslope may be near water table or may have greatest leaching due to water from upslope and rainfall were negative impact on the soils. This indicating that a need for application of integrated natural resource management in sustainable manner to optimize and maintain the soil physicochemical properties.
