The objective of this study was to investigate total, labile and stable soil carbon fractions at SRCs composed of poplar clones Max 1 (Populus nigra x P. maximowiczii), Muhle Larsen (Populus Trichocarpa), and black locust (Robinia pseudoacacia L.). Study was conducted at three SRC sites (Allendorf, Dornburg, and Forst) varying in age (1-4 years old), soil texture and climatic characteristics, in Germany. Composite soil samples collected at SRCs from 0 to 3; 0-10; 10-30; and 30-60 cm depth layers were compared with soils collected from adjacent crop strips. Samples were analysed for total organic carbon (TOC), hot-water extractable carbon (HWC), and organic carbon (OC) at 250-2,000; 53-250; and\53 lm soil-size aggregates. Total OC stocks in 0-60 cm soil layer were the highest at the site with the heaviest texture, Dornburg, followed by Forst and Allendorf, comprising 92-107; 59-74; and 53-64 Mg ha-1, respectively. Although no significant differences in the total OC stocks between SRCs and adjacent crops were found for the 0-60 cm layer, a significantly (p\0.05) higher TOC, HWC, OC at macroaggregates (250-2,000 lm), and the amount of macro-aggregates were found in the top 0-3 cm layer in all SRC sites (except the youngest poplar SRC in Forst) compared to adjacent crop strips. A greater macro-aggregate formation in SRCs related to the lower soil disturbance compared to the tilled crops, revealed a potential of SRC for C sequestration, as C occluded within soil aggregates has a slower decomposition rates and longer residence time.}, language = {en} } @misc{BoehmKanzlerFreese, author = {B{\"o}hm, Christian and Kanzler, Michael and Freese, Dirk}, title = {Wind speed reduction as influenced by woody hedgerows grown for biomass in short rotation alley cropping systems in Germany}, series = {Agroforestry Systems}, volume = {88}, journal = {Agroforestry Systems}, number = {4}, issn = {1572-9680}, doi = {10.1007/s10457-014-9700-y}, pages = {579 -- 591}, abstract = {The cultivation of fast growing trees on agricultural sites is an area undergoing a growth in interest due to the rising demand for woody biomass as a source of bioenergy. Short rotation alley cropping systems (SRACS) represent a promising possibility to combine annual crops for food, fodder or bioenergy with woody plants for biomass production, doing so through an integration of hedgerows of fast growing trees into conventional agricultural sites. Against such developments, the question has arisen as to what extent hedgerows in SRACS can act as an effective windbreak despite their management-related low height of only a few meters. On the basis of multiannual recorded wind velocity data in high resolution at two sites in Germany, it could be shown that the wind speed on crop alleys was reduced significantly by such hedgerows. At the central point of 24 m wide crop alleys, the wind speed decreased on an annual average basis by more than 50 \% when compared to the wind speeds of open field. The overall amount of reduction was strongly dependent on the location within the crop alleys, the height of trees, the distance between two hedgerows, and their orientation. In reflection upon these results, it was concluded that the establishment of SRACS could lead to enhanced soil protection against wind erosion and thus to ecological and economic benefits for agricultural sites.}, language = {en} } @misc{KanzlerBoehmFreese, author = {Kanzler, Michael and B{\"o}hm, Christian and Freese, Dirk}, title = {The development of soil organic carbon under young black locust (Robinia pseudoacacia L.) trees at a post-mining landscape in eastern Germany}, series = {New Forests}, volume = {52 (2021)}, journal = {New Forests}, number = {1}, issn = {1573-5095}, doi = {10.1007/s11056-020-09779-1}, pages = {68}, abstract = {The aim of this study was to evaluate the potential of short rotation alley cropping systems (SRACS) to improve the soil fertility of marginal post-mining sites in Brandenburg, Germany. Therefore, we annually investigated the crop alleys (AC) and black locust hedgerows (ABL) of a SRACS field trail under initial soil conditions to identify the short-term effects of tree planting on the storage of soil organic carbon (SOC) and its degree of stabilization by density fractionation. We detected a significant increase in SOC and hot-water-extractable organic C (HWEOC) at ABL, which was mainly restricted to the uppermost soil layer (0-10 cm). After 6 years, the SOC and HWEOC accumulation rates at ABL were 0.6 Mg and 46 kg ha-1 year-1, which were higher than those in the AC. In addition, comparatively high stocks of approximately 4.6 Mg OC and 182 kg HWEOC ha-1 were stored in the ABL litter layer. Density fractionation of the 0-3 cm soil layer at ABL revealed that the majority of the total SOC (47\%) was stored in the free particulate organic matter fraction, which was more than twice that of the AC. At the same time, a higher and steadily increasing amount of SOC was stored in the occluded particulate organic matter fraction at ABL, which indicated a high efficiency for SOC stabilization. Overall, our findings support the suitability of black locust trees for increasing the soil fertility of the reclaimed mining substrate and, consequently, the high potential for SRACS to serve as an effective recultivation measure at marginal sites.}, language = {en} } @misc{KanzlerBoehmMircketal., author = {Kanzler, Michael and B{\"o}hm, Christian and Mirck, Jaconette and Schmitt, Dieter and Veste, Maik}, title = {Microclimate effects on evaporation and winter wheat (Triticum aestivum L.) yield within a temperate agroforestry system}, series = {Agroforestry Systems}, journal = {Agroforestry Systems}, issn = {1572-9680}, doi = {10.1007/s10457-018-0289-4}, pages = {21}, abstract = {This study investigates the spatial and temporal impact of microclimate conditions caused by poplar hedgerows in a short rotation alley cropping system (SRACS), and their effect on the atmospheric evaporative demand (AED) and the grain crop yield of winter wheat (Triticum aestivum var.

Microclimate was measured at nine positions distributed at the SRACS and an adjacent open field in Brandenburg State (Germany) from March to August 2016. Our hypothesis was that microclimate and AED was improved at SRACS, with traceable effects on the crop yield. The analysis of air temperature and water vapour deficit (VPD) data revealed significantly (p B 0.05) lower daytime values from June to August at the crop alley of the SRACS, which were generally most frequent at the poplar hedgerow and 3 m west positions. By contrast, wind speed was reduced at almost all the positions of our crop alley and during the entire measurement period during both day and night. The AED measured on sampling days in July was significantly (p B 0.001) reduced at the whole crop alley, with values from 24 to 32\% in comparison to the open field. We observed a strong linear relationship (R2 \& 0.78-0.99) between AED on one side and wind speed and VPD on the other side. The average grain yield within the SRACS was 16\% higher than on the OF.

These ACS can be used for the simultaneous production of crops and woody biomass which enables farmers to diversify the provision of market goods. Integrating trees into the agricultural landscape can create additional benefits for the farmer and society also known as ecosystem services (ES). The scientific literature suggests that ACS are able to provide additional benefits as compared to conventional agriculture. Among the important ES provided by ACS are carbon sequestration, soil fertility, water quality, groundwater recharge, and biodiversity. However, assessment methods are required which are easy to use and provide reliable information regarding change in ES with change of the land use practice. In this context, our aim was to develop a methodology to assess selected ES provided by ACS in Germany. For this purpose an indicator set was selected from the literature and linked with the relevant ES previously identified. Furthermore, a model was developed to facilitate the calculation of the indicators. The results showed that ACS established at agricultural sites have higher capacity to provide ES as compared to single-crop agriculture. The capacity of ACS with 50\% trees is higher than the capacity of ACS with 30\% trees which suggests that the capacity of the system to provide ES increases with increased proportion of trees. The methodology seems to be a promising tool to facilitate the assessment of ES provided by the land management practices considered. In the long term this measurement approach can be broadened to include monetary evaluation of ES. This will enable rewarding farmers for providing environmental benefits therefore, accurately compensating them for the outputs supplied.}, language = {en} } @inproceedings{TsonkovaQuinkensteinBoehmetal., author = {Tsonkova, Penka and Quinkenstein, Ansgar and B{\"o}hm, Christian and Freese, Dirk}, title = {Selection of indicators to assess ecosystem services provided by alley cropping system}, series = {Book of abstracts of the 4th ESP Conference 2011 - Ecosystem Services: integrating Science and Practice; Workshop 1: Quantifying, mapping, and modeling of ecosystem services, held 4-7 October in Wageningen, Netherlands}, booktitle = {Book of abstracts of the 4th ESP Conference 2011 - Ecosystem Services: integrating Science and Practice; Workshop 1: Quantifying, mapping, and modeling of ecosystem services, held 4-7 October in Wageningen, Netherlands}, editor = {Burkhard, B. and Crossmann, N. and Nedkov, S.}, language = {en} } @inproceedings{BoehmQuinkensteinWoelleckeetal., author = {B{\"o}hm, Christian and Quinkenstein, Ansgar and W{\"o}llecke, Jens and H{\"u}ttl, Reinhard F.}, title = {Agroforestry Systems - Contribution of Alley Cropping to Ecosystem Services}, series = {Proceedings of the ASA, CSSA, and SSSA 2010 International Annual Meeting held in Long Beach, CA (USA) Oct. 31 to Nov. 4}, booktitle = {Proceedings of the ASA, CSSA, and SSSA 2010 International Annual Meeting held in Long Beach, CA (USA) Oct. 31 to Nov. 4}, publisher = {American Society of Agronomy [u.a.]}, address = {Madison, Wis.}, abstract = {Alley cropping system is an agroforestry practice in which arable crops are cultivated between tree hedgerows. For more than 15 ye ars we have been doing research in agroforestry which has been carried out on different experimental sites in the field covering about 250 acres of alley cropping, more areas with short rotation coppice, and other tree-based field experiments located close to C ottbus / Germany. The presence of woody species in the alley cropping production system has been shown to contribute significantly to carbon sequestration, nutrient cycling, improved water availability for crops, stimulation of higher soil faunal activities, soil erosion control, soil fertility improvement and sustained levels of crop production. Alley cropping systems have also come into focus for reclamation of post-mining areas where the initial content of soil organic matter (SOM) is generally close to zero and soil fertility is very low. The increase of SOM in reclamation areas depends on amount of biomass production and return to soil, and mechanisms of C protection. Production of Robinia pseudoacacia L. under alley cropping system has received considerable interest in these areas as an alternative to agricultural crops and an additional wood source, while acting as a potential C sink to counterbalance greenhouse gases emissions. The woody biomass accumulation of R. pseudoacacia reached 29.8 t drymass ha-1 after 6 years of establishment on reclaimed mine sites in northeastern Germany. Due to its high potential of litterfall production and N2 fixation, R. pseudoacacia contributed to improve soil physical, chemical and biological properties though increasing SOM, converting spoils into productive and sustainable soils. For this reason, in the temperate zone, agroforestry systems attract more and more public attention as they offer a promising and comprising way for adapting agricultural production to climate change and providing comprehensive ecosystem services. A comprehensive assessment of the ecosystem services in agroforestry systems in temperate regions should consider the potential to produce biomass and food, the evaluation of the carbon and nutrient budgets, the assessment of the potential impact of agroforestry on biodiversity at landscape scale and finally the exploration of the sustainability functions and socio-economic cross-cutting issues. These key parameters are relevant to policy by providing current and reliable information on the interactions between land management, ecosystem services and society.}, language = {en} } @inproceedings{TsonkovaBoehmQuinkensteinetal., author = {Tsonkova, Penka and B{\"o}hm, Christian and Quinkenstein, Ansgar and Freese, Dirk}, title = {Assessment of carbon sequestration provided by alley cropping systems for biomas production in Germany}, series = {Tagungsband zur 12.

Therefore, our project focuses on determining the water demand for biomass production of black locust in the Lusatia region (Eastern Germany). The area is characterized by relative low annual rainfall (560-600 mm/yr) and drought periods during spring and summer. Black locust (Robinia pseudoacacia L.) is planted in short rotation plantations as well as in agroforestry systems at reclaimed post-mining sites of the opencast mining area "Welzow S{\"u}d" and on a conventionally managed field near the town Forst (both study sites are located about 120 km to the south of Berlin). Due to mining activities the ground water table in "Welzow-S{\"u}d" is below 100 m, while on the field site in Forst the ground water table is about 2 m below the soil surface. Because of the water accessibility directly affecting the yield, it is crucial to identify the spatial variation of the soil water availability and its influence on black locust growth. The main question of this study is how the drought periods affect black locust's growth and recovery and about the drought mitigation effect obtainable by an accessible water table. The growth rate is being estimated monthly by measuring the maximum height and the trunk diameter at 10 and 130 cm. Furthermore, several trees are equipped with dendrometers to record their diameter increment in daily intervals. The pre-dawn water potential for selected trees is evaluated periodically to quantify plant water stress and relate it to the growth pattern. Water availability and microclimatic condition are monitored continuously. At the end of the vegetation period, information gathered from the field will be used to develop a growth model to link the soil water availability and plant water status with the growth rate of the trees.}, language = {en} } @inproceedings{QuinkensteinBoehmFreeseetal., author = {Quinkenstein, Ansgar and B{\"o}hm, Christian and Freese, Dirk and H{\"u}ttl, Reinhard F.}, title = {Short rotation coppice in post-mining landscapes - a promising land use system for biomass production in marginal regions}, series = {Agroforestry: A Profitable Land Use, Proceedings, 12th North American Agroforestry Conference, Athens, GA, June 4-9, 2011}, booktitle = {Agroforestry: A Profitable Land Use, Proceedings, 12th North American Agroforestry Conference, Athens, GA, June 4-9, 2011}, editor = {Ashton, Sarah F. and Workman, Sarah and Hubbard, William G. and Moorhead, David}, pages = {S. 68}, language = {en} } @inproceedings{BoehmFreeseSchmidtetal., author = {B{\"o}hm, Christian and Freese, Dirk and Schmidt, C. and H{\"u}ttl, Reinhard F.}, title = {Alley cropping - an option to combine crop and woody biomass production at degraded post-mining sites in Germany}, 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. 253}, language = {en} }
