The paper deals with morphological structure, physical-chemical and amphiphilic properties of soil organic matter in parcels of dominating tree species in the middle taiga zone of the Komi Republic. The study soils have similar morpho- logic structure, physical-chemical properties and profile distribution of amphiphilic fractions. The majority of migrating organic compounds accumulate in lower organic sub-horizons. Distribution of fractions in upper mineral sub-horizons depends on texture (granulometric composition) of soil-forming rocks. Profile distribution of hydrophilous fractions largely resembles total carbon distribution. Organic soil horizons differ by content of hydrophilous fractions which is at its maximum value in parcels with prevailing green mosses in soil cover and at its minimum value in parcel of lichen pine forest. Plant waste components which are precursors of soil organic matter greatly vary by content of amphiphilic fractions.
