Four-year investigations conducted as a field experiment aimed to determine the effect of organic fertilisation with farmyard manure, tannery sludge and vermicompost obtained from it on soil humus compounds composition. Equal to farmyard manure effect of vermicompost on organic carbon and total nitrogen was determined in the discussed experiment. Organic carbon content diminished as a result of mineral treatment and fertilisation with untreated sludge. The number of most mobile humus fractions decreased in result of applied fertilisation where as the share of humus compounds not undergoing hydrolysis increased.
