In the conditions of the Republic of Belarus there were presented results of research into humus and structural state of cultured agrozem of light-loamy granulometric composition. There were shown the peculiarities of composition of humic and fulvous acids. According to the results of 'dry' and 'wet' sifting there were calculated the coefficients of structure and criterion of water-tightness, on the basis of which there was estimated soil structure. It was shown that good aggregate state and watertight structure of agricultured horizon of the studied soil were determined by the content of humus and its qualitative composition.
