‘Colluvisols’ (Colluvi‐cumulic Anthrosols) are an important soil unit in North Germany. In the landscape of loamy till these soils are associated with eroded Luvisols. The soil organic matter (SOM) of top layers of both soils was compared by using approaches of wet chemistry, CPMAS 13 C‐NMR and pyrolysis field‐ionization mass spectrometry (Py‐FIMS). The Luvisols are sources of SOM transfer due to a continuous erosion process. The annual input of straw and plant residues induces the dominance of litter compounds like proteins, polysaccharides and lignin in the SOM. The Colluvisols are sinks of SOM transfer with a predominance of humic compounds. Lignin is degraded forming humic compounds with an alkylic and aromatic structure. In these soils selected compounds with higher mass signals were detected by Py‐FIMS, which may indicate the existence of typical “SOM markers” in the colluvic materials.
