The aim of the study was characteristic of carbon and nitrogen content in separated fractions of organic matter in arenosols and podzols. The content of organic carbon in the analysed fractions was as follows: bitumen 2.70-18.2, fulvic acids 9.50-59.8, humic acid 3.28-37.6. The content of nitrogen expressed as total amount and in fractions was differentiated among analysed profiles, and was significantly correlated with the content of organic carbon. The differentiated values of ratio C:N confirmed bog variability in the quality of organic matter depending on the type of soil and genetic horizons
