                      2014EGU General Assembly 2014The global demand for energy
                      security and the mitigation of climate change are the main
                      drivers pushing energy-plant production in Germany. However,
                      the cultivation of these plants can cause land use conflicts
                      since agriculturalsoil is mostly used for plant production.
                      A sustainable alternative to the conventional cultivation of
                      food-basedenergy-crops is the cultivation of special adopted
                      energy-plants on marginal lands. To further increase the
                      sustain-ability of energy-plant cultivation systems the
                      dependency on synthetic fertilizers needs to be reduced via
                      closednutrient loops. In the presented study the
                      energy-plant Sida hermaphrodita (Malvaceae) will be used to
                      evaluatethe potential to grow this high potential
                      energy-crop on a marginal sandy soil in combination with
                      fertilization viadigestate from biogas production. With this
                      dose-response experiment we will further identify an optimum
                      dose,which will be compared to equivalent doses of
                      NPK-fertilizer. Further, lethal doses and deficiency doses
                      will beobserved. Two weeks old Sida seedlings were
                      transplanted to 1L pots and fertilized with six doses of
                      digestate(equivalent to a field application of 5, 10, 20,
                      40, 80, 160t/ha) and three equivalent doses of
                      NPK-fertilizer. Controlplants were left untreated. Sida
                      plants will grow for 45 days under greenhouse conditions. We
                      hypothesize that thenutrient status of the marginal soil can
                      be increased and maintained by defined digestate
                      applications, compared tocontrol plants suffering of
                      nutrient deficiency due to the low nutrient status in the
                      marginal substrate. The dose of40t/ha is expected to give a
                      maximum biomass yield without causing toxicity symptoms.
                      Results shall be used asbasis for further experiments on the
                      field scale in a field trial that was set up to investigate
                      sustainable productionsystems for energy crop production
