      abstract     = {The global demand for energy security and mitigation of
                      climate change are the main drivers pushing energy-plant
                      production. However, the cultivation of these plants may
                      cause land use conflicts since agricultural soil is mostly
                      used for crop production for human and animal feed. A
                      sustainable alternative to the conventional cultivation of
                      food-based energy-crops is the cultivation of energy-plants
                      with the ability to grow on marginal lands. To further
                      increase the sustainability of energy-plant cultivation
                      systems the dependency on synthetic fertilizers needs to be
                      reduced via closed nutrient loops in the biomass production
                      cycle.In the present study we evaluated the ability of the
                      high potential energy-plant Sida hermaphrodita (Malvaceae)
                      to grow on a marginal sandy soil. We applied different
                      fertilization treatment using either digestate from biogas
                      production compared with a commercial mineral NPK-fertilizer
                      for a whole growth-period under outdoor conditions with
                      plants growing in large microcosms. To further increase
                      independency from synthetically produced N-fertilizers, the
                      legume plant Medicago sativa was intercropped to fix
                      atmospheric N2 into the cropping system and to produce
                      additional biomass.NPK fertilization created rapid growth in
                      the first months after planting compared to the organic
                      digestate application, but the latter extended the
                      vegetation period of Sida hermaphrodita by 20 days. Both
                      fertilization techniques showed a clearly increased biomass
                      production compared with the control plants without any
                      fertilization. Intercropped legume plants fixed additional N
                      into the cropping system and could increase the total
                      biomass production per area, even though they reduced the
                      yield of Sida. Highest biomass was observed in the
                      digestate-fertilized variant, intercropped with Medicago
                      sativa. Here the legume could increase the total yield by
                      $100\%$ resulting in a biomass dry matter yield equivalent
                      of 2.5t ha-1 after the first growing season.The presented
                      results show the yields of the establishment year. As Sida
                      hermaphrodita and Medicago sativa are perennial plants and
                      store assimilates in their rhizomes, yields are expected to
                      be considerably higher in the second year after the
                      establishment. We can show that marginal lands with soil
                      characteristics that do not meet the requirements for
                      conventional crops can be used for biomass production by the
                      use of perennial energy-crops like Sida hermaphrodita in
                      special adopted production systems.},
