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{LeopoldDethierVoelkeletal., author = {Leopold, Matthias and Dethier, David and V{\"o}lkel, J{\"o}rg and Raab, Thomas}, title = {Combining sediment analysis and seismic refraction to describe the structure, thickness and distribution of periglacial slope deposits at Niwot Ridge, Rocky Mountains Front Range, Colorado, USA}, series = {Zeitschrift f{\"u}r Geomorphologie}, volume = {52}, journal = {Zeitschrift f{\"u}r Geomorphologie}, number = {2}, doi = {10.1127/0372-8854/2008/0052S2-0077}, pages = {77 -- 94}, language = {en} } @misc{GerwinRaabBiemeltetal., author = {Gerwin, Werner and Raab, Thomas and Biemelt, Detlef and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {The artificial water catchment "Chicken Creek" as an observatory for critical zone processes and structures}, series = {Hydrology and Earth System Sciences}, volume = {6}, journal = {Hydrology and Earth System Sciences}, number = {2}, issn = {1812-2116}, doi = {10.5194/hessd-6-1769-2009}, pages = {1769 -- 1795}, language = {en} } @misc{GerwinRepmannSchaafetal., author = {Gerwin, Werner and Repmann, Frank and Schaaf, Wolfgang and Raab, Thomas}, title = {Bodenver{\"a}nderungen durch Waldbr{\"a}nde - Stoffvorr{\"a}te und Stoffverlagerungen}, series = {Jahrestagung der DBG 2022 "Grenzen {\"u}berwinden, Skalen {\"u}berschreiten" 5. - 8.

Dissolution of the cyanide, from Prussian Blue (ferric ferrocyanide), creates an environmental hazard, whereas the risk of groundwater contamination depends on the stability of dissolved iron-cyanide complexes. Lack of a standard leaching method to determine the water-soluble (plant-available) cyanide fraction generates potential limitations for implementing remediation strategies like phytoremediation. Applicability of neutral solution extraction to determine the water-soluble cyanide fraction and the stability of Prussian Blue in surface and near-surface soils of an MGP site in Cottbus, undersaturated and unsaturated water conditions, was studied in column leaching and batch extraction experiments. MGP soils used in the long-term tests varied according to the pH (5.0-7.7) and the total cyanide content (40-1718 mg kg-1). Column leaching, after four months of percolation, still yielded effluent concentrations exceeding the German drinking water limit (> 50 μg L-1) and the solubility of Prussian Blue reported in the literature (< 1 mg L-1) from both alkaline and acidic soils. Long-term (1344 h) extraction of MGP soils with distilled water was sufficient to dissolve 97\% of the total cyanide from the slightly alkaline soils and up to 78\% from the acidic soils. Both experiments revealed that dissolution of ferric ferrocyanide under circum-neutral pH and oxic water conditions is a function of time, where the released amount is dependent on the soil pH and total cyanide content. Unexpectedly high and continuous solubility of Prussian Blue, both in acidic and slightly alkaline MGP soils, implies the need to introduce an additional cyanide fraction ("readily soluble fraction") to improve and specify cyanide leaching methods. Long-term extraction of cyanide-contaminated soil in neutral solution seems to be a promising approach to evaluate the potential hazard of groundwater pollution at the MGP sites.}, language = {en} } @inproceedings{SutLohmannBoldtBurischRaab, author = {Sut-Lohmann, Magdalena and Boldt-Burisch, Katja and Raab, Thomas}, title = {Effect of ryegrass (Lolium perenne L.) roots inoculation using different arbuscular mycorrhizal fungi (AMF) species on sorption of iron-cyanide (Fe-CN) complexes}, series = {European Geosciences Union, General Assembly 2016, Vienna, Austria, 17 April - 22 May 2016}, booktitle = {European Geosciences Union, General Assembly 2016, Vienna, Austria, 17 April - 22 May 2016}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {Soils and groundwater on sites of the former Manufactured Gas Plants (MGPs) are contaminated with various complex iron-cyanides (Fe-CN).

In this paper, retention properties of the sandy loam soil and the potential vertical movement of the solid iron-cyanide complexes, co-existing with the dissolution, sorption and precipitation reactions were investigated. Preliminary research conducted on a former MGP site implied colloidal transport of ferric ferricyanide from the initial deposition in the wastes layer towards the sandy loam material (secondary accumulation), which possibly retarded the mobility of cyanide (CN). A series of batch and column experiments were applied in order to investigate the retardation of iron-cyanide complexes by the sandy loam soil. Batch experiments revealed that in circumneutral pH conditions sandy loam material decreases the potassium ferro- and ferricyanide concentration. In column experiments a minor reduction in CN concentration was observed prior to addition of iron sulfide (FeS) layer, which induced the formation of the Prussian blue colloids in circumneutral pH conditions. Precipitated solid iron-cyanide complexes were mechanically filtered by the coherent structure of the investigated soil. Additionally, the reduction of the CN concentration of the percolation solutions by the sandy loam soil was presumably induced due to the formation of potassium manganese iron-cyanide (K2Mn[Fe(CN)6]).}, language = {en} } @misc{SutLohmannBoldtBurischRaab, author = {Sut-Lohmann, Magdalena and Boldt-Burisch, Katja and Raab, Thomas}, title = {Possible evidence for contribution of arbuscular mycorrhizal fungi (AMF) in phytoremediation of iron-cyanide (Fe-CN) complexes}, series = {Ecotoxicology}, volume = {25}, journal = {Ecotoxicology}, number = {6}, issn = {1573-3017}, doi = {10.1007/s10646-016-1678-y}, pages = {1260 -- 1269}, abstract = {Arbuscular mycorrhizal fungi (AMF) are integral functioning parts of plant root systems and are widely recognized for enhancing contaminants uptake and metabolism on severely disturbed sites.

In this region the largest brown coal (lignite) mining area of Germany is located. Lignite mining activities lead to major disturbances of the landscape. Recultivation efforts attempt to regenerate mining areas for agricultural land use options. The geological "parent" material is of saaleian origin, has a sandy texture and was excavated from several meters depths before mining and is now used for recultivating the excavated area. Consequently, it is free of recent soil organic carbon. The substrate itself is unstructured. The partly wet or dry substrate is subjected to strong mechanical stresses during the excavation, deposition, refilling and levelling processes throughout the year. This practice leads to more or less compacted soils/substrates which may result in small yields of agricultural crops. In this context we investigate the effect of different organic soil additives in combination with different recultivation crop rotations on the development of soil structure for improved agricultural land use. Our experimental site has been heaped up and levelled off in 2006 and 2007. On each of the 24 experimental sub areas undisturbed soil samples have been taken to characterise the substrates according to their mechanical and hydraulic parameters and to determine the scattering of these parameters on a site that is assumed to be recultivated as homogenously as possible. First results of our ongoing experimental study indicate that the soil physical properties such as texture, bulk density, precompression stress, air permeability and saturated hydraulic conductivity are not identical on each of the 24 subplots. The soil physical properties behave differently in relation to each other.

The data correlate with the beginning of mining at the Vils River and hence suggest a causal connection with mining activities in the catchment—both on the slopes and in the floodplain—with intense deposition of flood loams.}, language = {en} } @misc{NiiAnnangRodionovRaabetal., author = {Nii-Annang, Seth and Rodionov, Andrei and Raab, Thomas and Bens, Oliver and H{\"u}ttl, Reinhard F. and Dilly, Oliver}, title = {Impact of Commercial Soil Additives on Microbial Activity and Carbon Isotopic Characteristics of Recultivated Post Lignite Mine Soils}, series = {Geomicrobiology Journal}, volume = {28}, journal = {Geomicrobiology Journal}, number = {7}, issn = {1521-0529}, pages = {567 -- 573}, language = {en} } @misc{RaabLeopoldVoelkel, author = {Raab, Thomas and Leopold, Matthias and V{\"o}lkel, J{\"o}rg}, title = {Character, Age, and ecological significance of pleistocene periglacial slope deposits in Germany}, series = {Physical Geography}, volume = {28}, journal = {Physical Geography}, number = {6}, issn = {1930-0557}, doi = {10.2747/0272-3646.28.6.451}, pages = {451 -- 473}, language = {en} } @incollection{StockBensHelbachetal., author = {Stock, Oliver and Bens, Oliver and Helbach, Christoph and Narra, Satyanarayana and Downes, Nigel K. and H{\"u}ttl, Reinhard F. and Raab, Thomas}, title = {Bodenphysikalische, wachstumskundliche und rechtliche Aspekte der Melioration stark toniger Kippsubstrate mit REA-Gips}, series = {Neue Ans{\"a}tze in der land- und forstwirtschaftlichen Rekultivierung}, booktitle = {Neue Ans{\"a}tze in der land- und forstwirtschaftlichen Rekultivierung}, editor = {H{\"u}ttl, Reinhard F. and Schneider, Bernd Uwe}, publisher = {BTU}, address = {Cottbus}, isbn = {978-3-937728-06-3}, pages = {45 -- 77}, language = {de} } @misc{HuerkampRaabVoelkel, author = {H{\"u}rkamp, Kerstin and Raab, Thomas and V{\"o}lkel, J{\"o}rg}, title = {Two and three-dimensional quantification of lead contamination in alluvial soils of a historic mining area using field portable X-ray fluorescence (FPXRF) analysis}, series = {Geomorphology}, volume = {110}, journal = {Geomorphology}, number = {1-2}, doi = {10.1016/j.geomorph.2008.12.021}, pages = {28 -- 36}, language = {en} } @misc{HuerkampRaabVoelkel, author = {H{\"u}rkamp, Kerstin and Raab, Thomas and V{\"o}lkel, J{\"o}rg}, title = {Lead Pollution of Floodplain Soils in a Historic Mining Area -

On very young landforms physical and chemical properties of soils play a major role for the further evolution of the developing ecosystem as well as the landforms itself. Less is known about the very first alterations of physical parameters in accordance to different land uses and recultivation practices. Our study deals with the agricultural recultivation of post lignite mining areas in Lusatia, East Germany. The sandy substrate used for recultivation stems from depths of several meters and is therefore free of recent soil organic matter. The substrate itself is unstructured. After it has been excavated and transported on conveyor belts to the recultivation site, it is piled up to dams of a height of 1-4 m and levelled off with heavy crawlers. During these processes the substrate is subjected to strong mechanical stresses. This practice induces compaction which causes decreasing yields of agricultural crops to a certain extent. In this context we are investigating the effect of different organic soil additives in combination with different recultivation crop rotations on the development of soil structure for improved agricultural land use. Our experimental site has recently been heaped up and levelled off. On the 25 experimental sub areas 2175 undisturbed soil samples were taken out of three soil depths to characterize initial physical properties before any recultivation measures have been applied,. We present laboratory results of this status-quo sampling. The results indicate that the site is very heterogeneous in terms of mechanical stability, bulk density, total pore volume, saturated hydraulic conductivity and air permeability. Moreover, our results show that bulk density is not an appropriate parameter to derive soil functions, e.g. permeability or stability. Additionally we found that even in areas of bulk densities > 1.8 g/cm3 and with an inclination < 2 \% impressive run-off and gully erosion developed during heavy rainfall events. We conclude that initial processes altering soil physical parameters play a major role for the landform evolution within the first 12 months after dumping. Further studies should reveal the mid-term impact of organic additives on the soils after 7 yrs.}, language = {en} } @inproceedings{RodionovBensTrimbornetal., author = {Rodionov, Andrei and Bens, Oliver and Trimborn, Manfred and Wagner, S. and Schneider, Bernd Uwe and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Use of commercial soil amendments in initial soils (I) - Impact on yield and basic soil characteristics}, 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 = {en} } @inproceedings{RissmannElmerHohbergetal., author = {Rißmann, Cornelia and Elmer, Michael and Hohberg, Karin and Raab, Thomas and Xylander, Willi E.

The observations comprised intermittent and continuous measurements or surveys on meteorological parameters (rainfall, temperature, vapour pressure deficit), soil (soil type and texture, soil chemistry and leaching, water content, soil temperature), deadwood, stand structure, vegetation regrowth, abundance of selected fauna (moths, beetles, mammals), UAV-based remote sensing (stand structure, spatial overview), and photo monitoring (succession).

The research aims to analyse industrial hemp species Santhica 27 feasibility for fiber cultivation and biomass production in water-scarce and nutrient-deficient sandy soils of Brandenburg. The impact of high (142 plants·m- 2) and low (71 plants·m- 2) planting densities on hemp´s morphological development and productivity, expressed as yields, is also assessed. The results showed that the dry condition with a water deficit of 168.9 mm during the growing period was the main factor significantly impeding hemp`s morphological development and fiber yields. Control treatments with the precipitation sum of 242 mm planted in a lower planting density had on average, significantly taller plants of 122 cm with greater total biomass yield of 3.74 t·ha- 1 dry weight compared to simulated water-scarce dry treatments, with the lowest plant height and total biomass of 69 cm and 1.91 t·ha- 1, respectively, when planted in high density. Although the N content in the original sandy soil was below 1 g·kg- 1, the dry environmental conditions had prompted N accumulation up to 35 N g·kg- 1 in hemp biomass, 18 N g·kg- 1 in lateral roots, and 13 N g·kg- 1 in tap roots. High calcium (Ca) content was found in hemp biomass and lateral roots, whereas potassium (K) content was greater in tap roots. The results suggest that a lower hemp planting density for hemp cultivation should be considered in a water-scarce and nutrient-deficient environment. Moreover, the elemental analysis showed that hemp parts contain considerable amounts of macronutrients, which could be of great importance to the sandy soil´s total nutrient-pool enrichment.}, language = {en} } @misc{SchueleHeinkenAdhikarietal., author = {Sch{\"u}le, Maren and Heinken, Thilo and Adhikari, Yojana and Binder, Anja and Clerc, Danica and Dobkowitz, Sophia and Francke, Till and Gerwin, Werner and Hartong, Heinrich and Jouy, Florent and Raab, Thomas and Repmann, Frank and Rohlfs, Lilly and R{\"o}nnefarth, Susanne and Ibisch, Pierre L.}, title = {Intensive post-fire management drives ecosystem degradation but does not prevent tree regeneration}, series = {Journal of applied ecology}, volume = {63}, journal = {Journal of applied ecology}, number = {1}, publisher = {Wiley}, issn = {0021-8901}, doi = {10.1111/1365-2664.70257}, pages = {1 -- 17}, abstract = {In recent years, wildfires have affected relatively large areas of managed forests in Central Europe. Often, forestry uses intensive post-fire management practices, which can have negative effects on various components of the ecosystem. Fire ecology has been largely neglected in Central Europe and strategies for appropriate management and successful reforestation of burned areas are urgently needed. We have studied the effects of different post-fire forest management treatments (including different levels of salvage logging and soil disturbances such as ploughing or raking) on soil parameters (phosphorus, nitrogen, calcium, potassium, magnesium, pH), microclimate (temperatures, vapour pressure deficit (VPD), heat and drought stress), deadwood, regrowth (biomass of tree regeneration, herb and bryophyte layer) and species richness (plants and saproxylic beetles) 3 years after wildfire in a Central European Scots pine forest (northeast Germany). Intensive forest management led to more unfavourable abiotic conditions, including stronger temperature extremes and elevated VPD. Consequently, vegetation on these sites experienced increased heat and drought stress and reduced nutrient availability. The biomass of the herb and bryophyte layer, as well as the species richness of plants and saproxylic beetles, was lower on completely salvage logged sites. Tree biomass recovered on all sites, including sites with intensive forest management. Tree regeneration in our study area was mainly driven by the recolonization of the pioneer species European aspen (Populus tremula), which can tolerate a wide range of site conditions. Synthesis and applications. We recommend avoiding intensive management on burned sites, such as complete salvage logging or ploughing, as this creates extreme site conditions that could inhibit the regeneration of more sensitive tree species and result in a long-term legacy of degradation. In addition, herb and bryophyte layers, as well as the species richness of vegetation and saproxylic beetles, which are important components of forest ecosystems, are negatively affected by intense forest management.}, language = {en} }
