For example, trees in agroforestry systems can provide shelter for wildlife and supply additional nutrients to adjacent arable fields through leaf litter inputs and fine root turnover. In addition, tree-strips have the ability to improve the groundwater quality underneath the tree-strip itself and possibly underneath adjacent fields. Unlike these commonly measured ecosystem services the microclimate conditions in temperate agroforestry systems are still a comparatively new study area (Kanzler et al. 2015, B{\"o}hm et al. 2014). This might be due to the complexity of the microclimate, which depends on various parameters such as the plant height, the planting density, and the orientation of the tree-strips. The objective of this study was to investigate the potential influence of tree-strips on microclimate using high resolution data loggers.}, language = {en} } @inproceedings{MirckKanzlerBoehm, author = {Mirck, Jaconette and Kanzler, Michael and B{\"o}hm, Christian}, title = {Ertragsleistung eines Energieholz-Alley-Cropping-Systems}, series = {B{\"a}ume in der Land(wirt)schaft - von der Theorie in die Praxis, Tagungsband mit Beitr{\"a}gen des 5.

However, alley cropping for woody biomass production is of interest because of its high potential to concurrently provide a biomass feedstock and an arable crop. One of the systems that exists, although at an experimental level, is the integration of rows of fast growing trees, such as poplar or willow, with arable crops. The experimental plots were initially established as part of the German joint research project "AgroForstEnergie - Economic and Ecological Evaluation of Agroforestry Systems in Farming Practice", funded by the German Federal Ministry of Food and Agriculture (AgroForstEnergie 2015). The goal of this project was to study alley cropping systems, which concurrently produce a woody biomass feedstock and conventional agricultural crops. Currently the work is continued through the AGFORWARD Project. The State of Brandenburg is known for its light sandy soils that are prone to wind erosion. The introduction of tree hedgerows within the agricultural landscape can reduce wind erosion (B{\"o}hm et al. 2014). In addition, microclimatic conditions such as soil moisture, wind speed reduction, relative humidity and air temperature have been more favourable for plant growth in crop alleys compared to reference crop areas (B{\"o}hm et al. 2014; Quinkenstein et al. 2009). Sugar beets are a common crop for conventional agricultural systems in Western Europe. As part of agroforestry systems, sugar beets have rarely been studied. Even though sugar beets can root up to a depth of 2 meter, their yields can be significantly reduced due to a lack of water (Hoffmann 2010; Bloch et al. 2006). Agroforestry systems that consist of tree hedgerows and crop alleys, also known as Alley Cropping Systems, have the potential to increase plant moisture in comparison to conventional agricultural systems (Quinkenstein et al. 2009). This study aims to assess tree hedgerow effects on sugar beets. The objectives of this study were to; 1) assess how tree hedgerows planted at three distances affected sugar beet yields; 2) to correlate soil moisture values of the top 15 cm with sugar beet yields at the same distance of the tree row; 3) to assess the effects of drought stress on sugar beet yield.}, language = {en} } @inproceedings{MirckKanzlerBoehmetal., author = {Mirck, Jaconette and Kanzler, Michael and B{\"o}hm, Christian and Freese, Dirk}, title = {Sugar beet yields in an alley cropping system during a dry summer}, series = {Social and technological transformation of farming systems: Diverging and converging pathways, 12th European IFSA Symposium, Newport, 12-15 July 2016, Book of Abstracts}, booktitle = {Social and technological transformation of farming systems: Diverging and converging pathways, 12th European IFSA Symposium, Newport, 12-15 July 2016, Book of Abstracts}, editor = {Wilcox, Andrew and Vinall, Samantha}, publisher = {Harper Adams University}, address = {Newport, Shropshire}, pages = {80 -- 82}, abstract = {Agroforestry (the integration of trees with crop and/or livestock production) offers a pathway to diversify agricultural production. Agroforestry systems have the potential to improve on-farm use of water through enhanced soil water holding capacities, the provision of shade, and the creation of wind shelter. These three characteristics can also improve the resilience of agricultural production in response to changing weather patterns. The objectives of this study were: 1) to measure how alley cropping systems with varying alley widths affect crop microclimate, 2) to measure the effects of this microclimate on sugar beet (Beta vulgaris) yields, and 3) to assess how moisture availability affects sugar beet growth patterns. Measurements were made in a 70 ha alley cropping system comprising black locust (Robinia pseudoacacia L.) and hybrid poplar Max1 (Populus suaveolens subsp. maximowiczii x P. nigra). A sugar beet crop was grown during the relatively dry growing season of 2015. Sugar beet yields were reduced in close proximity to the hedgerow, but yields were higher at and beyond an intermediate distance when compared with those in a nearby conventional agricultural field. Moisture availability significantly affected growth patterns of sugar beet roots.}, language = {en} } @inproceedings{MirckBoehmKanzleretal., author = {Mirck, Jaconette and B{\"o}hm, Christian and Kanzler, Michael and Freese, Dirk}, title = {Blattstreumengen in Geh{\"o}lzstreifen und angrenzenden Ackerbreichen innerhalb eines Agroforstsystems}, series = {Multifunktionale Agrarlandschaften - Pflanzenbaulicher Anspruch, Biodiversit{\"a}t, {\"O}kosystemdienstleistungen, 58.
