| Description
| - This paper is focused on soil organic mater quality assessment in acid forest soils. Soil samples were collected in the Jizera Mountains region. Vegetation cover ofsampling sites was formed by spruce or beech monocultures. Humus quality was assessed by theratio of absorabances of pyrophosphate soil extract at the wavelengths of 400 and 600 nm (A400/A600). Humus fractionnation was performed on selected soil samples. DRIFT spectra of individual fractions were measured. Higher pH and lower C and N contentes were found in beech forest than in spruce forest. A400/A600 well correlates with C and N contents (r= 0.510*** and 0.615***, respectively), C and N content increases as to humus quality decreases. DRIFT spectra of fulvic acids turned out to be unsiutable for describing differences in humus quality. DRIFT spectra of humic acids and humin were hence more suitable. The difference between spruce and beech forest was found in 1514.cm.-1(C=C bounds of benzene rings) and 1550 cm-1(N-H bounds in monosubstitu
