On the other hand, human impact on landscapes in Central Europe may date back to the earliest farmers from the Neolithic Period (c. 5500 a cal BC). At least since the Middle Ages intense land-use produced wide deforested areas. In the sand-rich North German Lowland these human-induced deforestation often resulted in the remobilisation of Late Pleistocene to Early Holocene sand dunes. Especially in the vicinity of former mining sites or glassworks the dune landscapes possess quite young stratigraphic disturbances (fossilized horizons, weak developed top soils). Within the scope of the Transregional Collaborative Research Centre (SFB/TRR) 38, funded by the Deutsche Forschungsgemeinschaft (DFG), inland dunes in South Brandenburg were used as comparison sites to study structures and processes of the initial ecosystem development phase in an artificial water catchment. Here, we present first results of the pedostratigraphy and the age of two dune systems near Glashuette which is about 50 km south of Berlin. Based on twelve Optical Stimulated Luminescence (OSL) and six radiocarbon (14C) datings a chronology of the landscape development for the last c. 10000 years is derived. Data prove that both dune systems - even though they are just c. 1 km apart and have similar morphological features such as height, width, and orientation - have a completely different history in aeolian sand deposition and pedogenesis. At dune 'Glashuette 1' a well established podsol forms the topsoil. At dune 'Glashuette 2' soil development is clearly in a more initial state showing only some humus accumulation and weaker podsolization processes. OSL and 14C ages of sand from 'Glashuette 1' range between about 11.4 ka cal. BC (3.9 m below surface) and 9.4 ka cal. BC (0.7 m below surface). Against that, the sands in 'Glashuette 2' are mainly dated to about 0.8 ka cal BC (3.4 to 0.7 m below surface). On the basis of our findings further analyses can be planned more accurately to study the impact of initial processes on the later state of ecosystems characteristics.}, language = {en} } @inproceedings{BensRaabSproeteetal., author = {Bens, Oliver and Raab, Thomas and Spr{\"o}te, Roland and Forman, Steven L. and H{\"u}ttl, Reinhard F.}, title = {Buried soils and dune sediments as archives of human-induced aeolian activity in the vicinity of historic glassworks, South Brandenburg, Germany}, series = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, booktitle = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {de} } @misc{DuemigVesteHagedornetal., author = {D{\"u}mig, Alexander and Veste, Maik and Hagedorn, Frank and Fischer, Thomas and Lange, Philipp and Spr{\"o}te, Roland and K{\"o}gel-Knabner, Ingrid}, title = {Biological soil crusts on initial soils: organic carbon dynamics and chemistry under temperate climatic conditions}, series = {Biogeosciences Discussion}, volume = {10}, journal = {Biogeosciences Discussion}, number = {1}, issn = {1810-6285}, pages = {851 -- 894}, language = {en} } @inproceedings{FischerSproeteVesteetal., author = {Fischer, Thomas and Spr{\"o}te, Roland and Veste, Maik and Wiehe, Wolfgang and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Functions of biological soil crusts on central European inland dunes:Water repellency and pore clogging influence water infiltration}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SproeteFischerVesteetal., author = {Spr{\"o}te, Roland and Fischer, Thomas and Veste, Maik and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Hydrophobicity in sandy soils triggered by the development of Scots Pine stands in southern Brandenburg, Germany}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SproeteFischerVesteetal., author = {Spr{\"o}te, Roland and Fischer, Thomas and Veste, Maik and Wiehe, Wolfgang and Lange, Philipp and H{\"u}ttl, Reinhard F.}, title = {Development of top soil on quaternary inland dunes - How important are microorganisms?}, series = {Gletscher, Wasser, Mensch - quart{\"a}rer Landschaftswandel im peribaltischen Raum, 35.

However, in South-Brandenburg (Germany), it is possible to study the development of biological soil crusts (BSC) during initial ecosystem genesis on two artificial water catchments with well-known ages and under differing starting conditions. The two experimental sites are located in the recultivation area of the lignite open-cast mining district of southern Brandenburg with a distance of approximately 1 km between them. Two different topographies were constructed at the experimental sites: the experimental plot at the catchment Neuer Lugteich was shaped like a dune, whereas the artificial water catchment H{\"u}hnerwasser was modelled as an inclined slope. The catchment Neuer Lugteich is four years older than H{\"u}hnerwasser. The original substrate at Neuer Lugteich is more sandy and carbonate-free compared to the original substrate dumped at H{\"u}hnerwasser. At both sites geomorphological differentiation and crust development were compared and the importance of substrate-dependent water availability and crust type clarified. Once settled, the crusts influenced the water regime of the soils by delaying infiltration through enhanced water repellency, and by limiting water infiltration. Chlorophyll analysis revealed that all crusts were at early stages of development. At Neuer Lugteich, the establishment of the biological soil crusts was closely associated with the vegetation succession, whereas no clear succession of the crusts could be observed at H{\"u}hnerwasser. The mosaic-like pattern of the biological soils crusts is associated with the distribution of fine-grained material here.zeige weniger}, language = {en} } @misc{DuemigVesteHagedornetal., author = {D{\"u}mig, Alexander and Veste, Maik and Hagedorn, Frank and Fischer, Thomas and Lange, Philipp and Spr{\"o}te, Roland and K{\"o}gel-Knabner, Ingrid}, title = {Organic matter from biological soil crusts induces the initial formation of sandy temperate soils}, series = {Catena}, volume = {122}, journal = {Catena}, doi = {10.1016/j.catena.2014.06.011}, pages = {196 -- 208}, abstract = {Different development stages of algae-dominated and moss-dominated biological soil crusts (BSCs) were sampled on a natural sand dune (b17 years old) and on an experimental sand dune (b8 years old) along a catena, including gradients of vegetation cover, location on the slope, as well as composition and thickness of BSC organisms in northeastern Germany. The accumulation of BSC-derived organic carbon (OC)was determined for bulk materials and fractions less than 63 μm. The OC composition was characterized by solid-state 13C NMR spectroscopy and the carbohydrate-C signature. 14C contents were determined to assess the origin and dynamics of OC. From the radiocarbon contents, two OC pools were differentiated: recent BSC-derived and lignite-derived "old" OC. Downward movement of OC into the underlying substratewas found only undermoss-dominated BSCs at the old sand dune. BSC-derived OC was mainly composed of carbohydrate-C and, to a lesser extent, alkyl C and N-alkyl C, with considerably higher contributions of alkyl C in the young dune, indicating differences in the composition of extracellular polymeric substances produced by the BSCs with age. This is consistent with higher proportions of water-soluble OC of moss-dominated BSCs at the old dune, which is leached in the underlying substrate and initiates soil formation. Because of the channeling effect of mosses, OC depth translocation along with suspended colloidal substances contribute to OC accumulation in substrates.}, language = {en} } @misc{HirschSproeteFischeretal., author = {Hirsch, Florian and Spr{\"o}te, Roland and Fischer, Thomas and Forman, Steven L. and Raab, Thomas and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {Late Quaternary aeloian dynamics, pedostratigraphy and soil formation in the North European Lowlands - new findings from the Baruther ice-marginal valley}, series = {Die Erde}, volume = {148}, journal = {Die Erde}, number = {1}, issn = {0013-9998}, doi = {10.12854/erde-148-30}, pages = {58 -- 73}, abstract = {The formation of dunes in central Europe reflects ample sediment supply during the last deglacial hemicycle.

An integrative approach, which combined geomorphological, sedimentological, pedological and chronological methods was used to identify aeolian deposition events, ensuing pedogenesis and anthropogenic remobilization. At the outcrops, which were situated approximately 2 km apart from each other, a total of twelve samples of the aeolian sands were dated using optically stimulated luminescence (OSL) and a further six samples using 14C dating. Although the dunes have similar morphological features, these forms have a different history of aeolian sand deposition and pedogenesis. At the older dune (Gl 1) the surface soil is a well developed Podzol, whereas soil development of the younger dune (Gl 2) is clearly in an initial state.

Auch die Bindungskr{\"a}fte zwischen den Partikeln spielen bei der Betrachtung des Einflusses der Benetzungshemmung / Hydrophobizit{\"a}t eine Rolle, denn es zeigt sich bei Betrachtung der Korngr{\"o}ßenverteilung, dass das Substrat in den Rekultivierungsgebieten der Bergbaufolgelandschaft unsortiert ist und hohe Anteile an Feinmaterial (Schluff und Ton) aufweisen kann.

Dort {\"u}bernehmen dann biologische Bodenkrusten und andere Mikroorganismen die Bindung und Festigung der Partikel z. B. durch extrazellul{\"a}re polymere Substanzen. Es wurde deutlich, dass die Akkumulation organischer Substanz bei Bewuchs mit Laubgeh{\"o}lzen in gr{\"o}ßerem Maße stattfindet als bei Bewuchs mit Nadelgeh{\"o}lzen.
