Abstract

In the course of the research, we provided detailed field morphological descriptions of the soils of Mount Tryokhgolovy Golets (Primorsky Ridge, Baikal region) and selected soil samples for chemical analyses. The soil diagnostics was performed using the “Classification and Diagnostics of Soils of Russia”, as well as the “Classification of Soils of Russia” website. A systematic list of the soils of the mountain under study and the surrounding area has been compiled. We have created a scheme of spatial distribution of soils of Mount Tryokhgolovy Golets. Analyses allowed us to determine the humus content, pH, and the granulometric composition of the soils. Results for some indicative key sites are presented in the article. The study area mainly consists of places affected to varying degrees by forest fires of different years. Forest fires have an impact on the soils of the Baikal mountains: in the soil that has been exposed to a forest fire, the humus layer burns out, the concentration of ash elements increases, pyrogenesis can enhance erosion processes in the mountains.
