Humus content and its properties on five locations in Sjenica region are studied and results obtained are presented in this paper. Humus content is high in all the soil types investigated. Total fulvic acids are predominant over total humic acids. Fraction of free humic acids bounded with mobile R2O3 is dominant in comparison with other humic acids fractions. Content of fulvic acid fraction bounded with free humic acids is higher when it is compared with other fulvic acids fractions. On two locations with the same type of soil under natural and cultivated grassland, there are not differences in humus content and composition between natural and cultivated grassland.
