Study of polydispersity of humic substances by the gel chromatography method

Molecular weight distribution of humic and fulvic acid preparations extracted from podzolic, peaty podzolic weakly gleyed, and arable soils is investigated. The effect of the agricultural use of soils on the fractional composition of humic compounds is assessed.
