Description	In samples of soil organic matter (SOM) from the humus profile of Šumava forest soils, the fractions of labile soil carbon Ccws, Chws, CPM and fraction of stable carbon represented by carbon of humus acids CHA and CFA were determined. Organic matter of samples was fractioned according to the degrees of hydrolyzability. The quality of labile fraction Chws was expressed on the basis of reaction kinetics as the rate constant of biochemical oxidation Kbio and rate constant of chemical oxidation Kchem of the first order reaction from a reduction in the concentration of C-compounds. The highest values of labile forms of carbon were determined in samples with the least favorable conditions for transformation processes of SOM, and these samples had the highest content of labile forms in hydrolyses by both methods.
