AbstractAfter vegetation fires considerable amounts of charred necromass are incorporated into soils and sediments. To elucidate its role in geobiochemical cycles a good understanding of its chemistry is crucial. Although several models describing char on a molecular level are reported in the literature (Schmidt & Noack, 2000), a commonly accepted view of the chemistry involved in Black Carbon (BC) production during vegetation fires is still missing. Therefore, the intention of the present work was to obtain some insights into structural properties of char produced during biomass burning by comparing results obtained from controlled charring experiments, the analysis of naturally charred soil organic matter with the pyrolysis literature.
