So können beispielsweise die Winderosion oder der Stoffaustrag in das Grundwasser durch den Anbau von Bäumen auf ackerbaulich genutzten Standorten deutlich reduziert werden. Durch die Kombination von Bäumen und konventionellen Ackerfrüchten (Agroforstwirtschaft) können auch angrenzende Feldfruchtbereiche und somit der gesamte Ackerschlag von diesen positiven Effekten des Agrarholzanbaus profitieren. Im Rahmen dieser Studie wurde beispielhaft untersucht, ob und inwieweit der streifenförmige Anbau (Alley-Cropping) von im Kurzumtrieb bewirtschaftetem Agrarholz einerseits zu einer Verbesserung des Windschutzes und andererseits zu einer Erhöhung der Grundwasserqualität beitragen kann.

N2 - Watersheds are often insufficiently known and have to be explored indirectly e.g. by means of geophysical methods. 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. Furthermore, the site will be the basis for (hydrological) model validation Y1 - 2008 N1 - H32D-01 INVITED ER - TY - CHAP A1 - Medinski, Tanya V.

T1 - Soil respiration in alley-cropping system composed of black locust and poplar trees, Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - Understanding of soil carbon dynamics after establishment of alley-cropping systems is crucial for mitigation of greenhouse gas CO2. This study investigates soil CO2 flux in an alley-cropping system composed of black locust (Robinia pseudoacacia L.) and poplar (Max 1) tree strips and adjacent to them crop strips (Lupinus/ Solarigol). 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. A greater C loss with soil respiration under trees in summer period may be compensated by greater C assimilation and storage in woody biomass, and the greater respiration from crop strips after tillage in autumn.

N. T1 - Alley Cropping - A promising multifunctional form of land use for reclaimed lignite mining sites in Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - Since the 1920s, more than 80.000 ha of land have been affected by lignite opencast mining activities in the Lusatia region (Eastern Germany), resulting in the evolution of large post-mining landscapes with substrates poor in humus and nutrients. 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-Süd” 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.

N. T1 - Impact of black locust hedgerows on wind velocity and wind erosion in Eastern Germany T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - The production of energy wood on arable land increased in Germany during the last years. 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.

T1 - Model-based analysis of the carbon sequestration potential of short rotation coppices on reclaimes lignite mine sites T2 - 2nd European Agroforestry Conference: Integrating Science and Policy to Promote Agroforestry in Practice, June 2014, Cottbus, Germany N2 - In Central Europe, short rotation coppice systems for the production of woody biomass come increasingly into focus as these wood plantations offer an opportunity to sustainably produce biomass for energy production and to sequester substantial amounts of CO2 within the plantations and the soils at the same time. 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.
