However, the tree rows in agroforestry systems, particularly in alley cropping systems (ACS), can affect crop productivity on adjacent agricultural fields through various mechanisms. Hence, concerns about declining yields and reduced farm profitability persist and explain the reluctance of farmers to implement ACS on their land. In this review, we examine the available literature on the effects of temperate ACS on yields of various agricultural crops to evaluate if and to what extent crop yields in ACS are affected by tree presence. We identified that ACS crop yields often vary substantially across different species, geographical locations, weather conditions and ACS designs. Our analysis also revealed that several parameters are modified in ACS by the presence of tree rows affecting crop yields positively or negatively and that ACS design aspects play a crucial role in determining crop productivity.}, language = {en} } @inproceedings{GruenewaldBaerwolffBoehmetal., author = {Gr{\"u}newald, Holger and B{\"a}rwolff, Manuela and B{\"o}hm, Christian and Schwarz, K.- U. and Schmidt, C.}, title = {Establishment of alley-cropping systems with short rotation woody crops 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. 119}, language = {en} } @inproceedings{BoehmWoelleckeElmeretal., author = {B{\"o}hm, Christian and W{\"o}llecke, Jens and Elmer, Michael and Quinkenstein, Ansgar and Freese, Dirk and H{\"u}ttl, Reinhard F.}, title = {Biodiversity in Agroforestry Systems}, 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. 598}, language = {en} } @inproceedings{Boehm, author = {B{\"o}hm, Christian}, title = {Erzeugung von Energieholz in Energiew{\"a}ldern und Agroforstsystemen}, series = {Innovationen f{\"u}r Klimaschutz und wirtschaftliche Entwicklung, 2.

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.}, language = {en} }
