Abstract
Pyrogenic changes of microelement content in soil and plants of the pine forests of West Transbaikalia (Republic of Buryatia) were studied. It was established that surface fires under the studied conditions cause changes of soil properties, insignificant increase in the concentrations of Mn, Zn, Cu, Pb in the upper layers of soil (0–40 cm) and Mn, Zn, Pb in plants. It was revealed that the ratio Fe : Mn in soil gets narrower. Investigations show that the pyrogenic change of vegetation and soil properties, in particular elemental composition, is observed during several years after the fire.
