The influence of fertilizing with brown coal and with the preparation containing brown coal called Reculter on properties of humic acids of Stagnic Luvisols and Gleyic Podzols soils was studied. It was found that, independent of a form of brown coal applied into soil, it causes enrichment of humic acids molecules in carbon and a distinct impoverishment in nitrogen, it also increases the resistance of humic acids to thermal decomposition. The content of organic carbon in soil samples and the amount of extracted humic substances are dependent on doses of Rekulter applied
