Impacts of wildfire low-severity on soil properties on 2 sampling plots of the dry pine forest in Western Transbaikalia are studied. Low-severity surface fires in the studied pine forests have a positive effect, since they activate the processes of litter decomposition and further dissolution of organic substances that provide soil and plants with accessible elements. Pyrogenic morphological features persist for a long period after a fire. These include the presence of black carbonaceous subhorizon at a depth of 14-14.5 cm, ocher mottles along the roots of burnt trees. These features are shown in the increased content of iron in the Tamm extract and exchangeable bases. This creates conditions for the fixation of humus associated ПРИРОДА ВНУТРЕННЕЙ АЗИИ № 4(22) 2022 NATURE OF INNER ASIAwith both calcium and iron hydroxides. Also there is a slight increase in the content of the clay fraction. Two years after the fire the properties of the soil change significantly. Eleven years after the fire, most soil properties are quickly restored to pre-fire levels.
