Recently, ACS which integrate stripes of short rotation coppices into conventional agricultural sites have gained interest in Germany. These systems can be used for simultaneous production of crops and woody biomass which enables farmers to diversify the provision of market goods. Adding trees into the agricultural landscape creates additional benefits for the farmer and society also known as ecosystem services. An ecosystem service provided by land use systems is carbon sequestration. The literature indicates that ACS are able to store more carbon compared to agriculture and their implementation may lead to greater benefits for the environment and society. Moreover, carbon sequestration in ACS could be included in carbon trading schemes and farmers rewarded additionally for the provision of this ecosystem service. However, methods are required which are easy to use and provide reliable information regarding change in carbon sequestration with change of the land use practice. In this context, our aim was to develop a methodology to assess carbon sequestration benefit provided by ACS in Germany. Therefore, the change of carbon in both soil and biomass had to be considered. To predict the change in soil carbon our methodology combined the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and the soil organic carbon balance recommended by the Association of German Agricultural Investigation and Research Centers (VDLUFA). To reflect the change in biomass carbon average annual yields were adopted. The results showed that ACS established on agricultural sites can increase the carbon stored because in the new soil-plant system carbon content is higher compared to agriculture. ACS have been recommended as suitable land use systems for marginal sites, such as post-mining areas. In such areas soil carbon usually increases at a faster initial rate compared to agricultural land which means that these areas could provide high level of carbon sequestration service in the short term. The approach will be broadened to include assessment of other ecosystem services provided by ACS in Germany which would increase the possibility to adequately compensate farmers for the supply of environmental benefits.}, language = {en} } @misc{VeldkampSchmidtMarkwitzetal., author = {Veldkamp, Edzo and Schmidt, Marcus and Markwitz, Christian and Beule, Lukas and Beuschel, Ren{\´e} and Biert{\"u}mpfel, Andrea and Bischel, Xenia and Duan, Xiaohong and Gerjets, Rowena and G{\"o}bel, Leonie and Graß, R{\"u}diger and Guerra, Victor and Heinlein, Florian and Komainda, Martin and Langhof, Maren and Luo, Jie and Potthoff, Martin and Ramshorst, Justus G.

Temperate agroforestry potentially improves ecosystem functions, although comprehensive analysis is lacking. Here, we measured primary data on 47 indicators of seven ecosystem functions in croplands and 16 indicators of four ecosystem functions in grasslands to assess how alley-cropping agroforestry performs compared to open cropland and grassland. Carbon sequestration, habitat for soil biological activity, and wind erosion resistance improved for cropland agroforestry (P ≤ 0.03) whereas only carbon sequestration improved for grassland agroforestry (P \< 0.01). In cropland agroforestry, soil nutrient cycling, soil greenhouse gas abatement, and water regulation did not improve, due to customary high fertilization rates. Alley-cropping agroforestry increased multifunctionality, compared to open croplands. To ameliorate the environmental benefits of agroforestry, more efficient use of nutrients is required.

In the most optimistic sequence of events pertaining to air temperature, precipitation, and global radiation, 35\% more woody biomass would be achieved by poplar and 43\% by black locust in the last period compared to the base period. Alternatively, in the most pessimistic circumstances, 54\% less woody biomass would be rendered by poplar and 47\% by black locust.

The definitions of marginality differ widely and also the scientific perspective on this type of land is very heterogeneous. However, with regard to the fast growing competition for arable lands between agricultural food production and the increasing need for growing renewable resources, such marginal lands could offer a mitigation option. Whereas agriculture is concentrating rapidly on the most fertile soils, the production of biomass as the renewable basis for various products could be shifted to sites with lower soil fertility. This in general is the main objective of the H2020 funded EU project SEEMLA (acronym for "Sustainable exploitation of biomass for bioenergy from marginal lands"). This project aims at an establishment of suitable innovative land-use strategies for a sustainable production of plant-based energy on marginal lands, while improving general ecosystem services. This approach will be tested in selected casestudy regions in Europe on marginal lands with different reasons for their marginality. One of the central tasks of this project was the characterization and classification of the investigated marginal sites according to a common definition. For that reason the Muencheberg Soil Quality Rating (SQR) system1 was adapted and applied at sites in Germany, Greece and Ukraine. This paper gives an overview of the importance and properties of different soil parameters and ecological site conditions for this classification. Even if the occurrence of the single site limitations epends on regional conditions, some generalizations are possible. Based on the respective dominating soil related restrictions, a classification of types of marginality and of marginal lands can be derived also with regard to their land use potentials for renewable resources. Further, cultivating biomass on marginal lands may offer remediation potentials with regard to the described ecological restraints of marginal sites.}, language = {en} } @inproceedings{BoehmQuinkensteinFreeseetal., author = {B{\"o}hm, Christian and Quinkenstein, Ansgar and Freese, Dirk and H{\"u}ttl, Reinhard F.}, title = {Energieholzproduktion in Agroforstsystemen als ein Beitrag zur Verbesserung des Bodenschutzes}, series = {Bodenschutz in Europa, Ziele und Umsetzung, 6.

Unlike previous reports, the study provides control for bacterial growth, biotic and abiotic CN losses. Bacterial growth, CN, ammonium, and nitrate concentrations were monitored regularly. Both strains grew less rapid with iron CN compared with the positive control. However, the growth was diauxic. The CN concentration in the media decreased with 20\% and 25\% respectively, while that in the sterile controls remained stable. Ammonium was detected in the media of both strains implying that a fraction of the initially applied ferrocyanide has been converted. The nitrogen lost from the system evened out with that in the cells at the end of the experiments.

Plant roots have developed adaptive strategies to enhance the availability of phosphorus, including producing and exuding low molecular weight organic acids with a high affinity for phosphorus that competes with high molecular weight organic ligands formed during humification and mineralization. The aim of this study was to characterize the kinetics and mechanism of phosphorus desorption from Fe- and Al-hydroxides of variable crystallinity, as well as binary Fe:Al-hydroxide mixtures. Long-term desorption experiments (56 days) were conducted with CaCl₂, CaSO₄, citric acid, and humic acid as competitive sorptives. CaCl₂ and CaSO₄ were selected as general inorganic sorptives and citric and humic acids were selected as organic ligands produced by organisms in the rhizosphere or following humification. The cumulative phosphorus desorption increased following the order CaCl₂< CaSO₄< humic acid < citric acid. Amorphous ferrihydrite and Fe-rich Fe:Al-hydroxides exhibited much less desorption when exposed to inorganic solutions than the crystalline and Al-rich Fe:Al-hydroxide mixtures. Models of the desorption data suggest phosphorus desorption with citric acid is diffusion- controlled for ferrihydrite and Fe-rich amorphous Fe:Al-hydroxides. When humic acid was the sorptive, metal-organic complexes accumulated in the solution. The results suggest organic compounds, especially citric acid, are more important for liberating phosphorus from Fe- and Al-minerals than inorganic ions present in the soil solution.}, language = {en} } @inproceedings{TsonkovaFreeseBoehmetal., author = {Tsonkova, Penka and Freese, Dirk and B{\"o}hm, Christian and Quinkenstein, Ansgar and Schaller, Eberhard}, title = {Benefits provided by silvoarable agroforestry systems in the temperate region: a review}, series = {Proceedings of the International Workshop on Agroforestry - Ecological Benefits of Agroforestry, 15-17 June 2011, Cottbus, Germany}, booktitle = {Proceedings of the International Workshop on Agroforestry - Ecological Benefits of Agroforestry, 15-17 June 2011, Cottbus, Germany}, editor = {Freese, Dirk and Pittruff, N. and Quinkenstein, Ansgar and B{\"o}hm, Christian}, pages = {S. 29}, language = {en} } @misc{FreeseBoehmKwasnickaetal., author = {Freese, Dirk and B{\"o}hm, Christian and Kwasnicka, Kamila and Quinkenstein, Ansgar and Uckert, G{\"o}tz}, title = {Kostensparend und {\"o}kologisch. {\"O}konomie und rechtlicher Rahmen f{\"u}r Agroforstsysteme}, series = {Neue Landwirtschaft}, journal = {Neue Landwirtschaft}, number = {1}, issn = {0863-2847}, pages = {91 -- 94}, language = {de} } @inproceedings{SchaafGerwinFreeseetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Freese, Dirk and B{\"o}hm, Christian and Kr{\"u}mmelbein, Julia}, title = {Initiale {\"O}kosystementwicklung, Rekultivierung und alternative Landnutzung in der Niederlausitzer Bergbaufolgelandschaft}, series = {B{\"o}den verstehen, B{\"o}den nutzen, B{\"o}den fit machen, Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, 3. - 9.

The mobility and bioavailability of P depends on adsorption, desorption and precipitation processes at soil mineral surfaces. In the soil matrix, P can be found in the forms of iron, aluminum or calcium complexes, adsorbed on mineral surfaces. P reactions in soil, especially the fixation on iron and aluminum (hydr) oxides, have been thoroughly studied. But the much slower process of P release has to be attended as well regarding the prospective supply of fertilizers and the use of plant available P pools in arable soils. The P adsorption ability of pedogenic oxides depends on their crystallinity, while soils contain both crystalline minerals such as goethite or ferrihydrite, as well as amorphous iron and aluminum compounds. In this study, long-term adsorption and desorption experiments were carried out to investigate the P binding mechanism during the sorption processes at certain time steps. For adsorption experiments, various experimental conditions such as pH, P ionic strength, competitive ions such as SO4 2- and Ca2+ as well as time will be considered. For desorption experiments, a Flow-Through-Reactor-Technique will be applied to investigate desorption kinetics and processes under nearly natural conditions without disturbance of the mineral-solution interface. Additionally, the release of P from the iron and calcium phosphates vivianite and hydroxyapatite, a main supplier of inorganic P and model substance for bone char, will be investigated. By using Fourier-Transformation-Infrared-Spectroscopy, changes of P binding mechanisms during ad- and desorption processes and easily as well heavily purgeable P can be detected.

During sludge treatment, the formation of vivianite has been identified, being mainly Fe-phosphate. Long-term P release from both hydroxyapatite and vivianite was studied using different inorganic (CaCl2 and CaSO4) and organic (citric and humic acid) reagents during batch experiments. Reagents CaCl2 and CaSO4 represent the soil solution, while citric and humic acids as organic constituents affect P availability in the rhizosphere and during the process of humification. Additionally, the flow-through reactor (FTR) technique with an infinite sink was used to study the long-term P release kinetics. The cumulative P release was higher by organic acids than by inorganic compounds. The cumulative P release rates were higher in the FTR with CaCl2 as compared to the batch technique. The infinite sink application caused a continuously high concentration gradient between the solid and liquid phases, leading to higher desorption rates as compared to the batch technique. The predominant amount of the total P released over time was available for a short term. While inorganic anion exchange occurred at easily available binding sites, organic acids affected the more heavily available binding sites, which could be embedded within the mineral structure. The results showed that organic compounds, especially citric acid, play a superior role as compared to the inorganic constituents of the soil solution during the recovery of already stored P from the tertiary phosphates vivianite and hydroxyapatite.}, language = {en} } @inproceedings{RepmannGerwinFreese, author = {Repmann, Frank and Gerwin, Werner and Freese, Dirk}, title = {Nachhaltige Biomasserzeugung zur energetischen Verwertung auf marginalen Standorten in Europa - Bewertung der Standortqualit{\"a}t}, series = {B{\"a}ume in der Land(wirt)schaft - von der Theorie in die Praxis, Tagungsband mit Beitr{\"a}gen des 5.
