The variability of physicochemical characteristics was investigated in the surface horizons of brown forest soils within the phytogenic fields of Mongolian oak (Quercus mongolica Fisch. ex Ledeb.) and Korean pine (Pinus Koraiensis Sieb. et Zucc.) growing in the southern Russian Far East. The relationships between the soil acidity, the type and content of humus, the optical parameters of the humic acids, and the phosphorus content were established as related to the orientation of the sectors of the phytogenic fields of trees and the distance of the sampling points from the trees. The heterogeneity of the soil conditions within the phytogenic fields of the tree species studied was assessed.
