Historical land use systems as shifting cultivation and plaggen agriculture on nutrient poor sandy soils caused serious degradation of soil and vegetation, resulting in Late Holocene sand drifting. Locally the coversand landscape was transformed into a driftsand landscape. On sheltered deposition sites polycyclic driftsand profiles developed. They are valuable geo-ecological records of alternating instable (sand drifting) and stable (soil formation) phases in landscape development. Previous research has been done on the reconstruction of the landscape genesis, based on pollen analysis and radiocarbon dating of polycyclic driftsand deposits. Recently, the application of Optically Stimulated Luminescence (OSL) dating improved the geochronology. The principles of pollen transport and deposition does not allow to select the plant species from pollen spectra, responsible for the on-site production of soil organic matter during soil formation in stable periods. A possible proxy for this, that ...
