Agroforestry systems in form of planted hedgerows have a long-term tradition as land-use systems in various European landscapes, primary in Denmark, North Germany and England. Planting of trees and shrubs into agricultural systems have economical benefits as they provide timber and and fuelwood and other products. It is well recognized, that these shelterbelts enhance biodiversity and have positive effects on the ecosystem functioning. In those contemporary agroforestry systems, selection of tree species and their management are more economically oriented towards an optimizing biomass production, use and harvest, especially in short-rotation systems for bioenergy. Our research focus on the ecophysiology and stress physiology of poplars (Populus spec.), black locust (Robinia pseudoacacia), and  willows (Salix spec.). Aim is to determined the water consumption and nutrient efficiency of the trees in relation to biomass production. Photosynthesis and water fluxes are measured on the tree level and scaled-up to the stand level. The experimental are carried out at different sites in southern Brandenburg (NE Germany) The research is in cooperation with the University of Hohenheim and integrated in the agroforestry research activties at the BTU Cottbus-Senftenberg.
