      abstract     = {Agroforestry systems are innovative agricultural systems,
                      which take advantage of beneficial ecological functions of
                      their components, aiming to attain high productivity with
                      possibly less negative environmental effects, e.g. nutrient
                      and carbon losses. However, no comparison of nutrient
                      response and retention efficiencies has yet been conducted
                      between conventional and agroforestry systems. Our study
                      aimed 1) to quantify nutrient response (ratio of biomass
                      production to soil available nutrients) and nutrient
                      retention efficiency (1-leaching losses/soil available
                      nutrient) in conventional and agroforestry systems, and 2)
                      to assess if competition and/or facilitation exists between
                      tree strip and grass/crop in agroforestry systems. We
                      hypothesized that conventional systems will have lower
                      nutrient response and retention efficiencies than
                      agroforestry systems. Our study investigated six paired
                      sites of grassland/cropland and agroforestry with alley
                      cropping of fast growing tree species and crop/grass,
                      located in central and eastern Germany. Measurements in
                      agroforestry were taken within tree strips and at various
                      distances to the tree strips within the crop/grass strips.
                      Results from the 2016/2017 growing season will be presented.
                      This study will provide the presently needed information on
                      whether agroforestry can reduce the negative environmental
                      impacts through gaseous/leaching losses while optimizing
                      production and therefore might be a sustainable alternative
                      to conventional agriculture.},
