Scanning electron microscopy (SEM) was used to characterize BSC morphology and microstructure. Infiltration was determined using microinfiltrometry under controlled moisture conditions in the lab. Water holding capacities were determined after water saturation of the dry BSCs. Wettability of the crusts was characterized using a "repellency index", which was calculated from water and ethanol sorptivities. Irrespective of the climate, an accumulation of fine particles in the BSCs was found, increasing along the catena from dune crest to dune base. Texture was finer and water holding capacities of the underlying substrate were higher at the arid site, whereas surface wettability was reduced at the temperate site. At both sites, BSCs caused extra water holding capacity compared to the substrate. Infiltration rates decreased along the catena and were generally lower at the dune slope and base of the arid site.

The Penman equation, which was developed for saturated surfaces, was modified for unsaturated surfaces and used for prediction of dewfall rates. The levels of surface saturation required for this approach were predicted using the water retention functions and the thicknesses of the BSCs. During a first field campaign (2-3 August 2011), dewfall increased from 0.042 kg m-2 for the initial sandy substrate to 0.058, 0.143 and 0.178 kg m-2 for crusts 1 to 3, respectively. During a second field campaign (17-18 August 2011), where dew formation was recorded in 1.5 to 2.75-h intervals after installation at 21:30 CEST, dewfall increased from 0.011 kg m-2 for the initial sandy substrate to 0.013, 0.028 and 0.055 kg m-2 for crusts 1 to 3, respectively. Dewfall rates remained on low levels for the substrate and for crust 1, and decreased overnight for crusts 2 and 3 (with crust 3 > crust 2 > crust 1 throughout the campaign). Dew formation was well reflected by the model response. The suggested mechanism of dew formation involves a delay in water saturation in near-surface soil pores and extracellular polymeric substances (EPS) where the crusts were thicker and where the water capacity was high, resulting in elevated vapor flux towards the surface. The results also indicate that the amount of dewfall was too low to saturate the BSCs and to observe water flow into deeper soil. Analysis of the soil water retention curves revealed that, despite the sandy mineral matrix, moist crusts clogged by swollen EPS pores exhibited a clay-like behavior. It is hypothesized that BSCs gain double benefit from suppressing their competitors by runoff generation and from improving their water supply by dew collection. Despite higher amounts of dew, the water availability to the crust community decreases with crust development, which may be compensated by ecophysiological adaptation of crust organisms, and which may further suppress higher vegetation or mosses.}, language = {en} } @misc{BrankatschkFischerVesteetal., author = {Brankatschk, Robert and Fischer, Thomas and Veste, Maik and Zeyer, Josef}, title = {Succession of N Cycling Processes in Biological Soil Crusts on a Central European Inland Dune}, series = {FEMS Microbiology Ecology}, volume = {83}, journal = {FEMS Microbiology Ecology}, number = {1}, issn = {1574-6941}, doi = {10.1111/j.1574-6941.2012.01459.x}, pages = {149 -- 160}, abstract = {Biological soil crusts (BSCs) are microbial assemblages that occur worldwide and facilitate ecosystem development by nitrogen (N) and carbon accumulation. N turnover within BSC ecosystems has been intensively studied in the past; however, shifts in the N cycle during BSC development have not been previously investigated. Our aim was to characterise N cycle development first by the abundance of the corresponding functional genes (in brackets) and second by potential enzyme activities; we focussed on the four processes: N fixation (nifH), mineralisation as proteolysis and chitinolysis (chiA), nitrification (amoA) and denitrification (nosZ). We sampled from four phases of BSC development and from a reference located in the rooting zone of Corynephorus canescens, on an inland dune in Germany. BSC development was associated with increasing amounts of chlorophyll, organic carbon and N. Potential activities increased and were highest in developed BSCs. Similarly, the abundance of functional genes increased. We propose and discuss three stages of N process succession. First, the heterotrophic stage (mobile sand without BSCs) is dominated by mineralisation activity. Second, during the transition stage (initial BSCs), N accumulates, and potential nitrification and denitrification activity increases. Third, the developed stage (established BSCs and reference) is characterised by the dominance of nitrification.}, language = {de} } @misc{XiaoWangFanetal., author = {Xiao, Bo and Wang, Huifang and Fan, Jun and Fischer, Thomas and Veste, Maik}, title = {Biological soil crusts decrease soil temperature in summer and increase soil temperature in winter in semiarid environment}, series = {Ecological Engineering}, volume = {58}, journal = {Ecological Engineering}, issn = {0925-8574}, doi = {10.1016/j.ecoleng.2013.06.009}, pages = {52 -- 56}, abstract = {In hot and wet conditions in summer, the biological soil crusts (BSCs) decreased soil temperature by up to 11.8 °C, 7.5 °C, 5.4 °C, and 3.2 °C at surface, 5 cm, 15 cm, and 30 cm, respectively; while in cold and dry conditions in winter the BSCs increased soil temperature by up to 1.2 °C, 1.2 °C, and 1.1 °C at 5 cm, 15 cm, and 30 cm, respectively.

The arid study site was located near Nizzana, in the northwestern Negev, Israel and the temperate site was near Lieberose, Brandenburg, Germany. BSCs were sampled at each site near the dune crest, at the center of the dune slope and at the dune base. The soil texture was finer and water holding capacities (WHCs) were higher in Nizzana, whereas surface wettability was reduced in Lieberose. At both sites, BSCs caused extra WHC compared to the mineral substrate. Infiltration after wetting along both catenas generally reached a maximum after 10 min and decreased after 30 min. Carbohydrates were the dominating components in all of the BSCs studied, where the relative peak areas of carbohydrate-derived structures (60-110 ppm) amounted to 28-46\% and to 10-14\% of total C-peak areas, respectively. PCA revealed that the WHC of the substrate was closely related to the amount of silt and clay, whereas the BSC induced extra WHC was closely related to carbohydrates. It was further found that water repellency was positively related to carbohydrate C, but negatively related to alkyl C. Infiltration kinetics was attributed to polysaccharide hydration and swelling. Our findings support the hypothesis that hydraulic properties of BSCs are determined by extracellular polymeric substances (EPS) and soil texture. Hydraulic properties in BSCs result from the combination of chemical properties related to C compounds mainly dominated by carbohydrates and physical surface properties related to texture, porosity and water holding capacity.}, language = {en} } @inproceedings{FischerVesteMykhailova, author = {Fischer, Thomas and Veste, Maik and Mykhailova, Larysa}, title = {Ecological Maturity and Drought Stress of Biological Soil Crusts along a Central European Inland Dune Catena}, series = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, booktitle = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{FischerYairGeppertetal., author = {Fischer, Thomas and Yair, Aaron and Geppert, Helmut and Veste, Maik}, title = {Water repellency and infiltration of biological soil crusts on an arid and a temperate dunes}, series = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, booktitle = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{LippertNixdorfLessmannetal., author = {Lippert, Gudrun and Nixdorf, Brigitte and Leßmann, Dieter and Henschke, Ingo and Veste, Maik and B{\"o}hme, Michael}, title = {Prim{\"a}rsukzession einem Kleingew{\"a}sser (H{\"u}hnerwasserteich) - Teil 2: Vergleich der Produktion von Phytoplankton, Makrophyten und heterotrophen Bakterien}, series = {Erweiterte Zusammenfassung der Jahrestagung der DGL 2009 in Oldenburg}, booktitle = {Erweiterte Zusammenfassung der Jahrestagung der DGL 2009 in Oldenburg}, publisher = {Eigenverlag der DGL}, address = {Hardegsen}, isbn = {978-3-9802188-8-7}, pages = {84 -- 89}, language = {de} } @inproceedings{FischerGypserSubbotinaetal., author = {Fischer, Thomas and Gypser, Stella and Subbotina, Maria and Veste, Maik}, title = {Hydraulic and nutritional feedback controls surface patchiness of biological soil crusts at a post-mining site}, series = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, booktitle = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{KleefeldVeste, author = {Kleefeld, Andreas and Veste, Maik}, title = {Robuste und strukturerhaltende Bildentrauschung via Medianfilterung und Bildsegmentierung}, series = {20. und 21.

Here we present an experimental design to test the emergence of seedlings in situ with (i) capping natural intact, (ii) destroyed and (iii) removed BSC. The selected field site is directly adjacent to the constructed H{\"u}hnerwasser catchment (Lusatia, Germany). This site exists since the end of 2008 and consists of loamy sand. Serving as proxy for seedling thrust, we inserted pre-germinated seeds of three confamiliar plant species with different seed masses (members of the Fabaceae family: Lotus corniculatus L., Ornithopus sativus Brot., and Glycine max (L.) Merr.). In each treatment as well as in the control group planting depths were 10 mm. We took care that experimental plots had identical crust thickness, slightly less than 4 mm, serving as proxy for mechanical resistance. A plot became established as follows: Firstly, the pristine crusted surface was vertically cut. To the windward side the BSC remained intact (i: "with BSC" stripe). To the downwind side soil material was temporarily excavated for laterally inserting the seeds beneath the surface of the first stripe. Then at the thereby disturbed second stripe pulverised BSC material became filled as a top layer (ii: "BSC mix" stripe). From the next stripe the BSC was removed (iii : "no BSC" stripe). Thus each plot had each experimental group in spatial contiguity (within 50 cm * 50 cm). The overall 50 plots were distributed across an area of 40 m * 12 m. When individuals of a species either emerged at all stripes, "XXX", or at no stripe of a plot, "- - -", there was no reason to suppose any effect of a crust. The "-XX" emergence pattern (depicting the appearance of seedlings in both stripes possessing manipulated surfaces) points towards hindrance more clearly than "-X-" or "- - X". Altogether eight possible combinations exist. Combinatorial analysis turned out that seedling emergence had been notably impeded for light-weighted seeds but little for heavy seeds. Repeated recordings enable to account for adaptable emergence of seedlings according to varying crust conditions - in spatial as well as temporal terms. The proposed experimental procedure hence is highly recommended as a viable instrument to further investigate filter and facilitation processes between BSCs and vascular plants.}, language = {en} } @misc{ZaplataSchuembergKidronetal., author = {Zaplata, Markus K. and Sch{\"u}mberg, Sabine and Kidron, Giora J. and Ramm, Jessica and Veste, Maik}, title = {Impacts of cyanobacteria-dominated biological soil crusts on seedling emergence and fate: an in situ experiment}, series = {Pant and Soil : an International Journal on Plant-Soil Relationships}, journal = {Pant and Soil : an International Journal on Plant-Soil Relationships}, doi = {10.1007/s11104-024-06869-3}, pages = {16}, abstract = {Background and aims Biological soil crusts (BSCs) co-occur with vascular plants in many ecosystems. Nevertheless, little is known regarding the interaction among BSCs and vascular plants, and no standard methods exist aiming to evaluate BSC-plant interactions. While some reports emphasized the inhibition effect of BSCs on germination, others reported the opposite or did not find any differences between germination under crusted and non-crusted conditions. Contradictory findings were also reported regarding the BSC effects on vascular plants after germination, with some reports claiming that BSCs promote growth, while others claim the opposite. Methods By a seed addition experiment (using light and heavy seeds of three species belonging to the Fabaceae family) in an early-successional system in Germany, we tested in situ the emergence of seedlings under variable surface conditions (cyanobacterial crust, disturbed and removed crust), and quantified crust-plant interactions (survival, flowering) during and following seedling emergence. Results In comparison to an average of 8\% of the light Lotus corniculatus and 20\% of the light Ornithopus sativus that emerged through the cyanobacterial BSC, 76\% of the heavy Glycine max emerged. Once emerged, the crust did not significantly affect the survival, growth, biomass, or flowering of G. max, whereas many of the seedlings from lightweight seeds dried up soon after emergence. The thickness of the cyanobacterial biocrust had no influence on Fabaceae emergence.

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 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} } @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 Yair, Aaron and Wiehe, Wolfgang and Lange, Philipp and Bens, Oliver and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Structures and processes of biological soil crusts during initial ecosystem genesis of an artificial watershed in Lusatia, NE Germany}, series = {EGU General Assembly 2010, held Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SproeteVesteFischeretal., author = {Spr{\"o}te, Roland and Veste, Maik and Fischer, Thomas and Raab, Thomas and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {Development of biological soil crusts and their influence on soil hydrology in the recultivation area of lignite open-cast mining district in Lower Lusatia (Germany)}, series = {EGU General Assembly 2012, held 22-27 April, 2012 in Vienna}, booktitle = {EGU General Assembly 2012, held 22-27 April, 2012 in Vienna}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, 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 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.

Here, we propose a research agenda to address this urgent question, focusing on physiological and ecological processes that link NVP to ecosystem functions while also taking into account the substantial taxonomic diversity across multiple ecosystem types. Accordingly, we developed a new categorization scheme, based on microclimatic gradients, which simplifies the high physiological and morphological diversity of NVP and worldwide distribution with respect to several broad habitat types. We found that habitat-specific ecosystem functions of NVP will likely be substantially affected by climate change, and more quantitative process understanding is required on (1) potential for acclimation (2) response to elevated CO2 (3) role of the microbiome and (4) feedback to (micro)climate. We suggest an integrative approach of innovative, multi-method laboratory and field experiments and eco-physiological modelling, for which sustained scientific collaboration on NVP research will be essential.}, language = {en} } @misc{SchaafBensFischeretal., author = {Schaaf, Wolfgang and Bens, Oliver and Fischer, Anton and Gerke, Horst H. and Gerwin, Werner and Gr{\"u}newald, Uwe and Holl{\"a}nder, Hartmut M. and K{\"o}gel-Knabner, Ingrid and Mutz, Michael and Schloter, Michael and Schulin, Rainer and Veste, Maik and Winter, Susanne and H{\"u}ttl, Reinhard F.}, title = {Patterns and processes of initial terrestrial-ecosystem development}, series = {Journal of Plant Nutrition and Soil Science}, volume = {174}, journal = {Journal of Plant Nutrition and Soil Science}, number = {2}, issn = {1522-2624}, doi = {10.1002/jpln.201000158}, pages = {229 -- 239}, abstract = {Ecosystems are characterized as complex systems with abiotic and biotic processes interacting between the various components that have evolved over long-term periods. Most ecosystem studies so far have been carried out in mature systems. Only limited knowledge exists on the very initial phase of ecosystem development. Concepts on the development of ecosystems are often based on assumptions and extrapolations with respect to structure-process interactions in the initial stage. To characterize the effect of this initial phase on structure and functioning of ecosystems in later stages, it is necessary to disentangle the close interaction of spatial and temporal patterns of ecosystem structural assemblages with processes of ecosystem development. The study of initial, less complex systems could help to better identify and characterize coupled patterns and processes. This paper gives an overview of concepts for the initial development of different ecosystem compartments and identifies open questions and research gaps. The artificial catchment site "Chicken Creek" is introduced as a new research approach to investigate these patterns and processes of initial ecosystem development under defined boundary conditions. This approach allows to integrate the relevant processes with related pattern and structure development over temporal and spatial scales and to derive thresholds and stages in state and functioning of ecosystems at the catchment level.}, language = {en} } @misc{VesteGerwinBiemeltetal., author = {Veste, Maik and Gerwin, Werner and Biemelt, Detlef and Fischer, Annette and Schaaf, Wolfgang}, title = {Monitoring of ecosystem patterns and processes in an artificial catchment in Lusatia, Germany}, series = {6th International Symposium on Ecosystem Behaviour BIOGEOMON 2009}, journal = {6th International Symposium on Ecosystem Behaviour BIOGEOMON 2009}, editor = {Ukonmaanaho, Liisa and Nieminen, Tiina Maileena and Starr, Michael}, publisher = {Finnish Forest Research Institute}, address = {Vantaa, Finland}, isbn = {978-951-40-2177-0}, pages = {S. 84}, language = {en} } @incollection{BiemeltVeste, author = {Biemelt, Detlef and Veste, Maik}, title = {Soil water}, series = {Initial development of the artificial catchment "Chicken Creek" : monitoring program and survey 2005-2008}, booktitle = {Initial development of the artificial catchment "Chicken Creek" : monitoring program and survey 2005-2008}, editor = {Schaaf, Wolfgang and Bliemelt, Detlef and H{\"u}ttl, Reinhard F.}, publisher = {Univ. of Technology, Research Center Landscape Development and Mining Landscapes}, address = {Cottbus}, pages = {57 -- 70}, language = {en} } @misc{FischerVesteBensetal., author = {Fischer, Thomas and Veste, Maik and Bens, Oliver and H{\"u}ttl, Reinhard F.}, title = {Dew formation on the surface of biological soil crusts in central European sand ecosystems}, series = {Biogeosciences discussions}, volume = {9}, journal = {Biogeosciences discussions}, doi = {10.5194/bgd-9-8075-2012}, pages = {8075 -- 8092}, abstract = {Dew formation was investigated in three developmental stages of biological soil crusts (BSC), which were collected along a catena of an inland dune and in the initial substrate. The Penman equation, which was developed for saturated surfaces, was modified for unsaturated surfaces and used for prediction of dewfall rates. The levels of surface saturation required for this approach were predicted using the water retention functions and the thicknesses of the BSCs. During a single event, dewfall increased with crust development from 0.08 kg m-2 for the initial substrate to 0.10, 0.20 and 0.25 kg m-2 for crusts stages 1 to 3, respectively, which was well reflected by the model response. The suggested mechanism of dew formation involves a delay in water saturation in near-surface soil pores and EPS where the crusts were thicker and where the water capacity was high, resulting in elevated vapor flux towards the surface. The results also indicate that the amount of dewfall was too low to observe water flow into deeper soil. Analysis of the soil water retention curves revealed that, despite the sandy mineral matrix, moist crusts with clogged by swollen EPS pores exhibited a clay-like behavior. It is hypothesized that BSCs gain double benefit from suppressing their competitors by runoff generation and from improving their water supply by dew collection. Despite higher amounts of dew, the water availability to the crust community decreases with crust development, which may be compensated by ecophysiological adaptation of crust organisms, and which may further suppress higher vegetation or mosses.}, language = {en} } @inproceedings{HuettlKoegelKnabnerZeyeretal., author = {H{\"u}ttl, Reinhard F. and K{\"o}gel-Knabner, Ingrid and Zeyer, Josef and Munch, Jean Charles and Gr{\"u}newald, Uwe and Pretzsch, Hans and Schaaf, Wolfgang and Gerwin, Werner and Veste, Maik}, title = {Structures and processes of the initial ecosystem development phase in an artificial water catchment}, series = {Plant Life in an Extreme and Changing Environment, Book of Abstracts}, booktitle = {Plant Life in an Extreme and Changing Environment, Book of Abstracts}, pages = {89 -- 90}, language = {en} } @misc{VesteBiemeltFischeretal., author = {Veste, Maik and Biemelt, Detlef and Fischer, Annette and Gerwin, Werner and Schaaf, Wolfgang}, title = {The "Point Zero": Monitoring of biogeochemical patterns and processes in an artificial ecosystem (Lusatia, Germany)}, series = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, journal = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SchaafGerwinVesteetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Veste, Maik and Biemelt, Detlef}, title = {Monitoring of Soil-Plant-Atmosphere patterns and processes in an artificial catchment}, series = {EGU General Assembly 2008, Wien}, booktitle = {EGU General Assembly 2008, Wien}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{KanzlerBoehmMircketal., author = {Kanzler, Michael and B{\"o}hm, Christian and Mirck, Jaconette and Schmitt, Dieter and Veste, Maik}, title = {Agroforstliche Nutzungsstrategien zur Sicherung der landwirtschaftlichen Produktion im Kontext steigender Urbanisierung und den Folgen des Klimawandels}, series = {Anfoerungen an den Pflanzenbau in einer sich urbanisierenden Welt, 60.

The results show a higher P sorption in the oldest site, and the average P sorption capacity (PSC) obtained in the oldest site was 21.0 mmol Kg-1, which was 3-4 times higher than the youngest site. However, all the values were very low compared with the optimum plant growth level, and low P desorption indicates a low level of plant-available P in the soil. The lower sorption properties with the small amount of oxalate iron (Feox) and oxalate aluminum (Alox) indicate the general P deficiency in the soil. However, a comparison from a previous study on the same experimental areas shows that not much improvement has occurred in soil P, and the change in soil P dynamics is very low.
