Abstract
The data of experimental research on the dynamics of post pirogenic gray humus soils of pine forests in the central ecological zone of the Baikal natural territory are analysed. Ground litter-humus fires transforms type diagnostic surface organic soil horizons, lead to the formation of new organogenic pyrogenic horizons (Opir). Negative impact of surface fires of varying intensity on stock change, quality of fractional composition of soil organic horizons, and their chemical composition is shown.
