This study aimed to identify soil properties in reforestation and logged area of Altanbulag soum of Selenge province in the northern part of Mongolia. In order to reveal soil chemical and physical properties changes between reforestation and logged area. We chose 2 sampling location from these soil data and collected 22 soil samples from 0-100cm depth of soil layers in 2020. By landscape positions SOM change differed. Result showed that the soil moisture of 5-50 cm depth of soil layer decreased by 40.5-68.7% and soil organic matter stock decreased by 6.3-23.8 t/ha logged area compared to reforestation, In the below 50 cm soil of depth no change of SOM, SOM stock, moisture, soil temperature. Impact of clearcut logging and climate warming on soil.
