Nevertheless, most of the reports compare soil properties under long-term sites. Thus, there exists little information on the effect of the conversion of silvopasture to arable or grassland use on soil P pools. The objective of the study was to determine the impact of converting silvopasture system (SP) into arable cropping and grassland system on the distribution of P pools and potential P bioavailability. We compared the following systems: SP system, SP converted to arable cropland (SP-AL), SP converted to grassland (SP-GL), and for comparative purposes, a long-term arable cropland (AL). The P fractionation was performed by a sequential extraction scheme, using acid and alkaline extractants on samples collected from the 0-10 and 10-20 cm soil layers. It was assumed that the large variations in soil-P fractionations are caused by the different management practices associated with land conversion. The results of P fractionation showed a dominance of calcium-bound P, HCl-extractable Pi constituted up to 36\% of the soil total P (TP). However, the type of land use did not affect this P fraction. On the other hand, the reduction in labile-Pi and NaOH-Pi fractions observed at the SP-AL site may have led to the decline in readily available P. The soil total organic P (TPo) content was 8\% and 17\% lower at SP-AL compared to SP and SP-GL site, respectively. Labile organic-P (labile-Po) content was markedly higher at SP site compared to arable soils, and was ≈ 10\% of TPo. The NaOH-Po constituted the highest fraction of the organic-P pool (55\%-79\% of TPo) across all the study systems, and was positively correlated with TPo (p < 0.01). The study indicates that conversion of SP system in temperate regions to arable cropping with conventional tillage seems to result in the reduction of P availability compared to SP, indicating SP as an important land-use practice.}, language = {en} } @misc{KayatzBaroniHillieretal., author = {Kayatz, Benjamin and Baroni, Gabriele and Hillier, Jon and L{\"u}dtke, Stefan and Heathcote, Richard and Malin, Daniella and Tonder, Carl van and Kuster, Benjamin and Freese, Dirk and H{\"u}ttl, Reinhard F. and Wattenbach, Martin}, title = {Cool Farm Tool Water: A global on-line tool to assess water use in crop production}, series = {Journal of Cleaner Production}, volume = {207}, journal = {Journal of Cleaner Production}, issn = {0959-6526}, doi = {10.1016/j.jclepro.2018.09.160}, pages = {1163 -- 1179}, abstract = {The agricultural sector accounts for 70\% of all water consumption and poses great pressure on ground water resources. Therefore, evaluating agricultural water consumption is highly important as it allows supply chain actors to identify practices which are associated with unsustainable water use, which risk depleting current water resources and impacting future production. However, these assessments are often not feasible for crop producers as data, models and experiments are required in order to conduct them. This work introduces a new on-line agricultural water use assessment tool that provides the water footprint and irrigation requirements at field scale based on an enhanced FAO56 approach combined with a global climate, crop and soil databases. This has been included in the Cool Farm Tool e an online tool which already provides metrics for greenhouse gas emissions and biodiversity impacts and therefore allows for a more holistic assessment of environmental sustainability in farming and agricultural supply chains. The model is tested against field scale and state level water footprint data providing good results. The tool provides a practical, reliable way to assess agricultural water use, and offers a means to engage growers and stakeholders in identifying efficient water management practices.}, language = {en} } @misc{QuinkensteinWoelleckeBoehmetal., author = {Quinkenstein, Ansgar and W{\"o}llecke, Jens and B{\"o}hm, Christian and Gr{\"u}newald, Holger and Freese, Dirk and Schneider, Bernd Uwe and H{\"u}ttl, Reinhard F.}, title = {Ecological benefits of the alley cropping agroforestry system in sensitive regions of Europe}, series = {Environmental Science \& Policy}, volume = {12}, journal = {Environmental Science \& Policy}, number = {8}, issn = {1462-9011}, doi = {10.1016/j.envsci.2009.08.008}, pages = {1112 -- 1121}, language = {en} } @misc{NiiAnnangGruenewaldFreeseetal., author = {Nii-Annang, Seth and Gr{\"u}newald, Holger and Freese, Dirk and H{\"u}ttl, Reinhard F. and Dilly, Oliver}, title = {Microbial activity, organic C accumulation and 13C abundance in soils under alley cropping systems after 9 years of recultivation of quaternary deposits}, series = {Biology and Fertility of Soils}, volume = {45}, journal = {Biology and Fertility of Soils}, number = {5}, issn = {1432-0789}, doi = {10.1007/s00374-009-0360-4}, pages = {531 -- 538}, language = {en} } @misc{MatosFreeseSlazaketal., author = {Matos, Eduardo da Silva and Freese, Dirk and Slazak, Anna and Bachmann, Ute and Veste, Maik and H{\"u}ttl, Reinhard F.}, title = {Organic-carbon and nitrogen stocks and organic-carbon fractions in soils under mixed pine and oak forest stands of different ages in NE Germany}, series = {Journal of plant nutrition and soil science}, volume = {173}, journal = {Journal of plant nutrition and soil science}, number = {5}, issn = {1522-2624}, pages = {654 -- 661}, language = {en} } @misc{SlazakFreeseMatosetal., author = {Slazak, Anna and Freese, Dirk and Matos, Eduardo da Silva and H{\"u}ttl, Reinhard F.}, title = {Soil organic phosphorus fraction in pine-oak forest stands in Northeastern Germany}, series = {Geoderma}, volume = {158}, journal = {Geoderma}, number = {3-4}, issn = {0016-7061}, pages = {156 -- 162}, language = {en} } @misc{MatosFreeseMendoncaetal., author = {Matos, Eduardo da Silva and Freese, Dirk and Mendon{\c{c}}a, Eduardo S. and Slazak, Anna and H{\"u}ttl, Reinhard F.}, title = {Carbon, nitrogen and organic C fractions in topsoil affected by conversion from silviopastoral to different land use systems}, series = {Agroforestry Systems}, volume = {81}, journal = {Agroforestry Systems}, number = {3}, issn = {1572-9680}, pages = {203 -- 211}, language = {en} } @misc{QuinkensteinPapeFreeseetal., author = {Quinkenstein, Ansgar and Pape, Dirk and Freese, Dirk and Schneider, Bernd Uwe and H{\"u}ttl, Reinhard F.}, title = {Biomass, Carbon and Nitrogen Distribution in Living Woody Plant Parts of Robinia pseudoacacia L.
