      abstract     = {Perennial non-food energy crops are currently discussed as
                      a more sustainable alternative to conventional energy crops
                      like maize. As they can be cultivated on marginal soils,
                      they reduce the risk of land use and food vs. fuel
                      conflicts. In this study, we evaluated the perennial energy
                      crop Sida hermaphrodita for its potential to be cultivated
                      on marginal substrate and conventional agricultural soils
                      over a three-year field and mesocosm experiment at
                      agricultural conditions. Furthermore, we aimed for a closed
                      nutrient loop by fertilizing plants with biogas digestate
                      and using the carbon fraction of the digestate as soil
                      amendment to ameliorate the overall soil fertility. As
                      controls, plants were either untreated or fertilized with an
                      equivalent amount of mineral NPK fertilizer. We found S.
                      hermaphrodita to give highest DM yields of up to 28 t ha−1
                      under favorable soil conditions when fertilized with mineral
                      NPK. However, on marginal substrate digestate fertilization
                      resulted in a clear biomass yield advantage over NPK
                      fertilization. An increased soil carbon content, water
                      holding capacity and basal soil respiration indicated
                      improved soil fertility in the marginal substrate. These
                      results demonstrate the great potential of S. hermaphrodita
                      to be cultivated on marginal soil in combination with
                      organic fertilization via biogas digestate.},
