Mollisols are known to contain stable, black humus components which originate from
charred or coal-derived particles. As such black carbon (BC) significantly affects soil
fertility and interferes with models on soil organic matter dynamics, an accurate prediction of BC input into soils and an elucidation of the mechanisms of BC turnover
is essential. The main aims of this study were (i) to identify the sources of BC in the
