      abstract     = {Biochars have long been associated with elevating plant
                      productivity. An increasing number of studies, however,
                      report that char application might also impair plant
                      nutrient availability and reduce yields. In particular, char
                      accompanying compounds as well as a hypothesized
                      immobilization of nitrogen have been identified as playing a
                      significant role in possibly diminishing plant productivity
                      following char application. Herein, we tested the
                      fertilizing effects of modified biochars in order to derive
                      knowledge required to develop tailor-made chars, which
                      predictably affect plant nutrition. Slow-pyrolysis maize cob
                      biochar was modified by washing with either ethanol or
                      hydrochloric acid to remove ash and organic compounds or by
                      loading it with nutrient-rich residues in the form of
                      digestate from the bioenergy sector. Maize plants were grown
                      for 35 days on biochar-amended sand. We analyzed both
                      substrate properties (pH, total carbon, and nitrogen,
                      available magnesium and potassium) and plant functional
                      traits (biomass, leaf area, root to shoot ratio, specific
                      leaf area). Our results suggest that total plant biomass
                      production remained unaffected by the application of biochar
                      and its washed forms. Contrastingly, nutrient-loaded biochar
                      induced a significant increase in productivity at similar
                      nutrient levels due to improved plant nutrient uptake.
                      Further research is required to understand the role of
                      biochar modifications that facilitated improvements in plant
                      productivity.},
