Abstrakt: This paper discusses the relationship between the slope exposure and chemical and microbiological soil properties on agricultural terraces. Terraces formed on limestone and shale rocks in the medium-altitude zone of the eastern Caucasus were studied. It is established that the slope exposure significantly affects the properties of soils formed on similar parent rocks. The formation of terraces with nearly horizontal arable surfaces changes the sunlight angle of incidence, thus increasing the heat supply to soils on north-facing slopes and reducing the heat supply to soils on south-facing slopes. Such changes in the thermal regime in the upper horizon of terrace soils reduce the differences in chemical and microbiological properties between soils on north- and south-facing slopes as compared to the background soils. On gentle (5°–15°) slopes with the greatest terrace width, the leveling effect of terracing is more strongly expressed in comparison with soils of narrow terraces formed on steep slopes.
