                      production of biomass is a strategy for reducing land use
                      conflicts between food and energy crops. Digestates can be
                      used as fertilizer and for soil amelioration. In order to
                      promote plant growth and reduce potential adverse effects on
                      roots because of broadcast digestate fertilization, we
                      propose to apply local digestate depots placed into the
                      rhizosphere. We grew Sida hermaphrodita in large mesocosms
                      outdoors for three growing seasons and in rhizotrons in the
                      greenhouse for 3 months both filled with marginal substrate,
                      including multiple sampling dates. We compared digestate
                      broadcast application with digestate depot fertilization and
                      a mineral fertilizer control. We show that depot
                      fertilization promotes a deep reaching root system of S.
                      hermaphrodita seedlings followed by the formation of a dense
                      root cluster around the depot-fertilized zone, resulting in
                      a fivefold increased biomass yield. Temporal adverse effects
                      on root growth were linked to high initial concentrations of
                      ammonium and nitrite in the rhizosphere in either fertilizer
                      application, followed by a high biomass increase after its
                      microbial conversion to nitrate. We conclude that digestate
                      depot fertilization can contribute to an improved
                      cultivation of perennial energy-crops on marginal soils.},
