FRACTIONAL COMPOSITION OF HUMUS IN SOD-PODZOLIC SOILS OF BREST POLESYE

Full Text:

Abstract

The results of the study of the fractional composition of sod-podzolic soils (albeluvisols) of Brest Polesie are given. Ascertained low organic carbon content (typically less than 1 %) in the humus horizon, the drop in the total content with depth, humate-fulvic humus composition. In the composition of humic and fulvic acids dominate mobile fractions, whose share falls to 70 % in the forest soil to 50 % in the arable soil. Content and composition of humus in soils studied are practically independent of particle size distribution.
