Rumpel, C., Kögel-Knabner, I., Becker-Heidmann, P., Hüttl, R. F. (1996): Multiple causes for elevated carbon content in recultivated mine soils in Lausatia, Germany. – In: Bottrell, S. H.

In the post-mining landscapes of Lusatia, different sources of carbon can be identified in forest soils, which developed from Tertiary, extremely acid, lignite-rich open cast mine spoils. The sites have been ameliorated with ash from lignite-fired power stations prior to afforestation. Bulk soil as well as particle size Fractions were analysed for elemental composition, magnetic susceptibility, chemical structure by CPMAS 13C NMR spectroscopy and 14C age. In the surface soil organic carbon from recently formed soil organic matter, from lignite and melioration lignite ash occur in intimate mixture. Furthermore, contamination with different types of airborne lignite particles, which has an impact over large areas in Lusatia, was observed.
