In course of the research there was studied the fractional composition of sod-podzolic soils (albeluvisols) of Brest Polesye. The researches were realized in the conditions of the Republic of Belarus on the Polesye territory in 2011-2013. As a result of realized research low organic carbon content (typically less than 1%) in the humus horizon, the sharply drop of the total content with depth, humate-fulvic humus composition were ascertained. In the composition of humic and fulvic acids dominated mobile fractions, whose share decreased to 70% in the forest soil and to 50% in the arable soil. Content and composition of humus in studied soils were practically independent from texture. Humus stocks in humus-accumulating horizons of sod-podzolic soils of Brest Polesye, humus content of under various land types and various granulometric content, distribution of humic substances in fractions of the degree of connectivity of the organic matter with the mineral part of the soil of various farm land, content of humic substances fractions of sod-podzolic soils of various granulometric content were presented.
