Comparison of extractable soil carbon and dissolved organic carbon by their molecular characteristics
Original language description
The aim of this study was to compare the molecular characteristics of extractable soil carbon from biotopes of the Rašeliník watershed and dissolved organic carbon (DOC) from Rašeliník creek, by using the 0.1 M pyrophospate, 0.01 M CaCl2 and Britton-Robinson buffer as extraction agents. The molecular weight Mr and weight-average molecular wight Mw determined by the low pressure size exclusion chromatography. Elution curves of all humic substances were characteristic by two peaks with predominant low-molecular fraction. Mr and Mw values of aquatic humic substances were 5.9 and 7.9 kDa, respectively, and proportion of this low-molecular fraction reached 97%. This corresponds to the fact, that the main fraction of HS in surface waters constitute fulvic acids. Using soil extraction in CaCl2 we obtained the fraction of organic carbon similar to the humic substances contain in DOC.
