It is native from North America and its original range is a climatic region classified as humid to sub-humid, with a mean annual precipitation of 1.020 to 1.830 mm. However, in Central Europe the species has proven to be relatively drought tolerant in comparison to other temperate deciduous tree species. In the State of Brandenburg (Germany) for instance, with a continental climate and annual precipitation below 600 mm, the species has been successfully cropped for wood production for more than 250 years. The tree notably grows also in post-mining recultivated sites where soil water availability is limited and in spring and summer drought can occur. The importance of the species has increased over the lasts decades, after the CO2 reduction policy spread across the world, just as did the need for further sources for renewable energy. Therefore, due to its adaptability to water constraints, its fast growing and resprouting rate, together with the ability of nitrogen fixation, black locust could become a key species for short-rotation plantation on marginal land. Several studies have been already carried out to quantify the production and water use efficiency of the black locust. However, the effect of water scarcity on biomass production and the plant's response to drought stress has still to be examined. In ourinvestigation we aim to evaluate the growth performance and the ecophysiological response of black locust to water limitation. The study of the soil-plant-atmosphere system for the evaluation of the relation between water availability, atmospheric evaporative demand and plant water status is critical to identify the ecophysiological adaptation and growth response in relation to different edaphic and climatic conditions. Different irrigation regimes and cycles of drought were chosen, to test the plant's performance in a lysimeter experiment for the duration of two vegetation periods, under semi-controlled environmental conditions. The results obtained from studies were satisfactory. We assessed the drought tolerance and resilience of black locust, together with its water use efficiency. Both at whole-plant and leaf level the link between the soil water retention, plant water status and growth rate has been elucidated and the intertwined relation between primary production, transpiration, CO2 uptake and water limitation, together with the evaporative atmospheric demand, has been clarified.}, language = {en} } @inproceedings{QuinkensteinMatosFreeseetal., author = {Quinkenstein, Ansgar and Matos, Eduardo da Silva and Freese, Dirk and Jochheim, Hubert and Schneider, Bernd Uwe and H{\"u}ttl, Reinhard F.}, title = {Estimating the carbon sequestration potential of short rotation coppice on marginal sites: a model approach}, series = {Book of Abstracts, 2nd World Congress of Agroforestry, Agroforestry - The Future of Global Land Use}, booktitle = {Book of Abstracts, 2nd World Congress of Agroforestry, Agroforestry - The Future of Global Land Use}, publisher = {World Agroforestry Centre}, address = {Nairobi, Kenya}, isbn = {978-92-9059-255-6}, pages = {S. 164}, language = {en} } @inproceedings{KruemmelbeinFischerRaabetal., author = {Kr{\"u}mmelbein, Julia and Fischer, Scarlett and Raab, Thomas and H{\"u}ttl, Reinhard F.}, title = {Bodenphysikalische Kenngr{\"o}ßen und deren fl{\"a}chenhafte Heterogenit{\"a}t auf einer homogen hergestellten Fl{\"a}che der Bergbaufolgelandschaft in der Lausitz}, series = {B{\"o}den - eine endliche Ressource, Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, 5. bis 13.

Being a ruderal species and relatively drought tolerant compared to other broad leaf trees, its use in agroforestry systems will increase. That is particularly true for marginal landscapes characterized by adverse edaphic conditions, where the soil water availability is limited and in summer drought can occur. Several studies have been carried out on the subject of the black locust primary production; however there are still open questions associated with its water consumption and the biomass production, in relation to the soil water availability. In order to investigate the soil-plant-atmosphere system interactions, in our studies the links between the growth rate, water use efficiency and the ecophysiological response have been examined in a two year lysimeter experiment. The two years old black locust plants were selected from a recultivated post-mining area (Welzow S{\"u}d, Lusatia, Brandenburg) and established in a 100 L wicked lysimeter, installed under a light transmissive roof to avoid uncontrolled water input. During the first vegetation period, the trees were maintained constantly under three different soil moisture regimes (well-watered, moderate, drought), in relation to the hydrostatic state of the lysimeters. For the second vegetation period instead, the plants were subjected to two different irrigation cycles (long term drought stress, short term drought stress), in relation of the drought stress and recovering time duration. The results were satisfactory. At whole plant level the water use efficiency, the growth rate under different soil moisture conditions and the morphological adaptation to drought condition were assessed. In addition, at leaf level we elucidated the relation between the soil moisture together with the atmospheric evaporative demand and the ecophysiological performance in terms of H2O and CO2 rate variation. From the results emerged that the black locust cultivar may have a positive or negative effect on the ecosystem function, depending on the water availability of the areas in object. The tree can tolerate periods of drought by reducing its transpiration rate, yet it is not to be considered a water saving trees species in a well watered condition.}, language = {en} } @inproceedings{HalkeGypserMantovanietal., author = {Halke, Christian and Gypser, Stella and Mantovani, Dario and Lebzien, Stefan and Freese, Dirk and Veste, Maik}, title = {Yield, transpiration and growth of the new bioenergy crop IGNISCUM Candy under different water regimes}, series = {Gf{\"O} 43rd Annual Meeting, Building bridges in ecology, linking systems, scales and disciplines, September 9 to 13, 2013, Potsdam, Germany}, booktitle = {Gf{\"O} 43rd Annual Meeting, Building bridges in ecology, linking systems, scales and disciplines, September 9 to 13, 2013, Potsdam, Germany}, editor = {Jeltsch, Florian and Joshi, Jasmin}, pages = {32 -- 33}, abstract = {There is a growing global need to produce more energy and reducing greenhouse gas emissions. One possible source of renewable energy in parts of Europe is the use of crop for bioenergy production. Currently, maize dominates the biogas production. For a diversified production of substrates alternative crops needs to be evaluated for their sustainable utilization and ecological integration into agro-systems. The new bioenergy plants IGNISCUM Candy and IGNISCUM Basic are cultivars of the Sakhalin Knotweed (Fallopia sachalinensis, Fam. Polygonaceae), which are characterized by a high annual biomass production. Information on the crop production of this species is rare. Hence, understanding plant response to the combinations of water and nutrients availability is crucial for the development of sustainable plant production. In greenhouse experiments we investigate the interrelations between nutrient supply, biomass production, and plant ecophysiology. For the determination of yield-transpiration relations at whole plant level we used a wick lysimeter system, which allows us to study plant growth under controlled water regimes and to calculate the plant transpiration. The irrigation is supplied by an automatic drip irrigation system and computer-controlled in relation to the volumetric soil water content. Four different water treatments associated to the SWC range from well-watered to drought stressed plants. The influence of plant sizes on plant water use was investigated under different nitrogen supply. The fertilizer applied is calcium ammonium nitrate (N) and the rates for the four treatments are 0, 50, 100, 150 kg N/ha at the beginning of the growing season. Plant transpiration is calculated on the basis of water input, storage and drainage in weekly intervals. The cumulative transpiration of the plants during the growing season is between 49 L (drought stressed) and 141 L (well-watered) per plant, respectively.

We determined the concentration, chemical composition, radiocarbon age, and bioavailability of DOC along the hydrological flow path from soil solution to a downstream pond in a recently constructed catchment (Chicken Creek Catchment, Germany). Soil solution, upwelling ground water, subsurface water in an alluvial fan, and pond water all had high DOC concentrations (averaged 6.0 - 11.6 mg DOC L-1), despite small carbon stocks in either vegetation or soil of the catchment. The mean 14C age of DOC in upwelling ground water was 2600 to 2800 years. Solid-state CPMAS 13C NMR revealed a higher proportion of aromatic compounds (32\%) and a lower proportion of carbohydrates (33\%) in upwelling ground water compared to pond water (18\% and 45\%, respectively). 14C age and 13C NMR spectra suggest that DOC was partly mobilized from charred organic matter inherent in the Quaternary substrate. In a 70-days incubation experiment, 20\% of the total DOC was found to be bioavailable, irrespective of the water type. Origin of the microbial communities within the catchment (enriched from soil, stream sediment or pond water) had only marginal effects on overall DOC utilization. Overall, our data suggest that both recent and old DOC support microbial activity during early ecosystem succession, although a large fraction of the DOC is recalcitrant and eventually exported from the catchment once it has been mobilized.}, language = {en} } @inproceedings{BoehmKanzlerFreese, author = {B{\"o}hm, Christian and Kanzler, Michael and Freese, Dirk}, title = {Agroforstsysteme in S{\"u}dbrandenburg - Effekte auf Mikroklima und Wasserqualit{\"a}t}, series = {Nachhaltige Erzeugung von Nachwachsenden Rohstoffen, Tagung vom 04. bis 06.

Therefore, important parts of the system often remain 'black boxes'. In addition, natural systems are characterized by huge complexity and heterogeneity. To overcome these disadvantages artificially created watersheds may play an important role in ecosystem research. They offer the chance to investigate systems with well defined boundary conditions and inner structures. Furthermore, artificial watersheds might be an important link between lysimeter research and investigations at the landscape scale. The artificial catchment "Chicken Creek" ('Huehnerwasser') is one of the world's largest man-made catchments for scientific purposes. It was established in 2005 with an area of 6 ha (450 m x 150 m) including a small lake. The site is located in the Eastern German lignite mining district near Cottbus, about 150 km southeast of Berlin. The watershed was constructed by Vattenfall Europe Mining AG as the operator of the still active lignite open-cast mine Welzow-South. Construction work was done by means of large mining machines in co-operation with the Brandenburg University of Technology at Cottbus. The inner structure of this new landscape element is relatively simple: A clay layer was dumped as a barrier for seepage water overlaid by a 3 m sandy layer consisting of Quaternary substrate from Pleistocene sediments. The surface of the site has been flattened and the area was fenced to prevent disturbances. Neither amelioration nor any reclamation measures were carried out afterwards. The site has been left for an unrestricted natural succession. In 2007 the Transregional Collaborative Research Centre (SFB/TRR 38) as a joint project between 3 Universities (BTU Cottbus, TU Munich and ETH Zurich) was launched and is funded by the German Research Foundation (DFG). The project group investigates the initial genesis of ecosystems with the Chicken Creek catchment as its main research site. A comprehensive monitoring programme is investigating the development of hydrological, pedological, geomorphologic and biological patterns and processes. It is planned to establish a structure and process model for this catchment to describe the initial development phase of an ecosystem in detail.

Soil CO2 flux was measured monthly over the March - November 2012 period, using a LI-COR LI-8100A automated device. Simultaneously with CO2 flux measurements, soil and air temperature, soil moisture, microbial C and hot water-extractable carbon (HWC) were determined for soils collected nearby each measurement collar. Root biomass was measured to a depth of 15 cm. In all sampling areas, soil CO2 flux increased from May to July, showing a significant positive correlation with air and soil temperature, which can be a reflection of increase in photosynthetic activity over the warm summer months. The relationships between soil moisture and CO2 flux showed positive correlation only for the warm period (May - October), indicating enhancing role of soil moisture on microbial mineralization and root respiration. CO2 flux values varied between sampling areas at different vegetation periods, with significantly higher values in trees over the summer. This could be attributed to the higher photosynthetic activity and higher root density in trees coppices compared to crops. In autumn, after seeding catch crop mix Solarigol, CO2 flux was significantly higher in crops compared to trees, which could be related to soil tillage prior to seeding of crops, as well as to the higher photosynthetic activity of newly seeded crops at the period of rapid plant growth. Despite a seasonal variation in CO2 flux between sampling areas, aaverage CO2 flux values observed over March - November period did not differ significantly between sampling areas, showing 2.5, 3.2, and 2.9 μmol m-2 s-1 values for black locust, poplar and crops, respectively.

As a consequence, the current conventional crop production on these post-mining areas is restricted. Against this background, the increasing demand for woody biomass for bioenergy, and thus the cultivation of fast growing trees for woody biomass production, could represent a promising option to enhance the productivity of land reclaimed from mining. Accordingly, considerable research has been carried out over the last two decades on reclamation technology, in addition to attempts to improve the soil quality through the use of different fast growing tree species in the Lusatia lignite region. Through such studies, it has been shown that it is possible to cultivate a sustainable supply of bioenergy wood through the use of black locust (Robinia pseudoacacia L.) trees, even under the unfavourable growth conditions of the marginal post mining areas. Since this knowledge is mainly based on studies of monocultural plantations (SRC), in 2007 a short rotation alley cropping system (SRACS) was established in the reclaimed lignite mining site "Welzow-S{\"u}d" with the purpose of obtaining fresh insight. The present paper evaluates the positive impacts of agroforestry land-use in terms of soil fertility, agricultural crop production, and soil protection against wind erosion based on the results of several years of examination made in this degraded area.}, language = {en} } @inproceedings{BoehmKanzlerFreese, author = {B{\"o}hm, Christian and Kanzler, Michael and Freese, Dirk}, title = {Impact of black locust hedgerows on wind velocity and wind erosion in Eastern Germany}, series = {2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany}, booktitle = {2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany}, editor = {Palma, Joao H.

Black locust (Robinia pseudoacacia L.) is a suitable tree species in order to ensure substantial woody biomass yields on agricultural sites in eastern Germany. Arranged in hedge structures (alley cropping) positive effects on wind velocity and hence on soil erosion can be expected for the whole agricultural production area. Results of field measurements carried out in several alley cropping sites located in eastern Germany show that wind velocity can be reduced by more than 50 \%, even though tree hedgerows were not higher than four meters. Here, the reduction of wind speed was dependent on the distance to woody crops, the width of the crop alleys and the orientation of hedgerows. As a result of wind speeds reduction the potential of soil erosion by wind decreases considerably. The risk of wind erosion is even nearly negligible for 24 m wide or smaller crop alleys. The establishment of short rotation hedgerows could contribute to an enhanced protection against wind erosion and thus to an ecological and possible long-term economic appreciation of agricultural sites. Aside from erosion control, further advantages such as a lower evaporation rate, and thus a crop yield increase, may be connected to the establishment of such agroforestry systems. Against the background of the increasing demand for woody biomass for bioenergy, the cultivation of fast growing trees on agricultural sites can furthermore result in an additional incomefor farmers. This is a prerequisite for the spread of this kind of agroforestry in Germany, because a comparable large share of an unprotected field has to be planted with trees in order to ensure an efficient windbreak.}, language = {en} } @inproceedings{QuinkensteinJochheim, author = {Quinkenstein, Ansgar and Jochheim, Hubert}, title = {Model-based analysis of the carbon sequestration potential of short rotation coppices on reclaimes lignite mine sites}, series = {2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany}, booktitle = {2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany}, editor = {Palma, Joao H.

In this study, a modeling analysis of the C cycle of a poplar (Populus suaveolens Fisch. x Populus trichocarpa Torr. et Gray cv Androscoggin) and a black locust (Robinia pseudoacacia L.) SRC is presented. The calculations were performed with the bookkeeping C-model shortcar. The calculated estimates of C accumulation within the biomass, the litter layer, and the soil were validated against field data and published results from a selection of scientific studies. For the SRC on reclaimed mine sites a high C sequestration potential was found which amounted in the reference scenario over a period of 36 years to an accumulated net biome production of about 65 Mg C ha-1 for R. pseudoacacia and about 9 Mg C ha-1 for poplar, while the latter clearly suffered from the harsh growth conditions at the reclamation sites. Summarizing, the results suggested a high potential of SRC for C sequestration and C emission mitigation, especially on marginal sites.}, language = {en} } @inproceedings{KanzlerBoehmFreese, author = {Kanzler, Michael and B{\"o}hm, Christian and Freese, Dirk}, title = {N{\"a}hrstoffgehalte und Ertr{\"a}ge von Kartoffeln in Abh{\"a}ngigkeit zur Entfernung vom Geh{\"o}lzstreifen in einem Agroforstsystem}, series = {Tagung der Gesellschaft f{\"u}r Pflanzenbauwissenschaften e.V. mit der Max-Eyth-Gesellschaft Agrartechnik VDI-MEG, 16.-18.
