Potential and Mechanisms for Stable C Storage in the Post-Mining Soils under Long-Term Study in Mitigation of Climate Change

Carbon storage in soil increases along with remediation of post-mining soils. Despite many studies on the issue carbon sequestration soils, there is a knowledge gap potential and mechanisms C areas. This research, including nuclear magnetic resonance analysis, determines organic formation progress long-term study limestone (S1), lignite (S2) under different stages. The main target reforesting; however, S2 was previously amended sewage sludge. showed that for S1, O-alkyl groups were dominant fraction sequestered soil. However, S2, increased fractions acetyl-C aromatic within observed. S1 resulted improved hydrophobicity humification; decrease groups’ C/N ratio noted. For we noticed an increase all indicators stability, which has been assigned to used sludge techniques. While both soils huge sequestration, much higher properties indicating its stabilization can suggest non-amended (S1) require more time stable C.
