Abstract

• The aim of this study was to evaluate chemical changes in soil organic matter (SOM) in organically and conventionally managed fields, using pyrolytic indices and the extraction of different carbon fractions. Pyrolysis-gas chromatography (Py-GC) was used to study structural changes in SOM, whereas the different soil extractions gave a fractionation of C forms. Organic management increased both humic and labile C forms (microbial biomass C and water soluble organic C). A significant positive relationship was found between the living SOM fraction, expressed as microbial biomass/total organic C ratio (MBC/TOC) and humification rate. A negative relationship was found between the pyrrole to phenol ratio (O/Y) and total extractable C (TEC). An opposite trend has been observed for the second pyrolytic index (N/O), which represents the mineralization of fresh organic matter. Mineralization was higher in organically managed soil, probably because of consistent input of fresh material to the organic field. Carbon fraction pools and pyrolytic indices provided complementary indications of SOM quality under organic and conventional management. (literal)
