      abstract     = {The amendment of biochar to agricultural soils is presumed
                      to mitigate global warming through long-term carbon (C)
                      sequestration. In addition, biochar may support microbial
                      biomass and diversity as well as plant growth by the
                      improvement of soil properties. So far, no information is
                      available on the stability of biochar and the effects of
                      biochar on soil microbial and plant properties under
                      predicted soil warming at the field scale. We investigated
                      the impacts of biochar addition (Miscanthus pyrochar, 30 t
                      ha−1, August 2013) and long-term soil warming (+2.5 °C,
                      since July 2008) and their interactive effects on microbial
                      biochar-C utilization and physical, chemical and microbial
                      soil properties of a silty-loamy stagnic Luvisol in a
                      temperate agroecosystem (Stuttgart, Germany) over one year
                      under winter rapeseed (Brassica napus). Three months after
                      biochar application (November 2013), microbial abundances
                      remained unaffected, indicating that readily available C
                      from fresh biochar had been consumed before sampling.
                      However, we found evidence for initial decomposition of more
                      recalcitrant biochar-C by fungi under soil warming after
                      three months. We suggest that the added biochar was very
                      stable, since increased biochar degradation by fungi could
                      not be detected after seven and twelve months. Nevertheless,
                      during spring 2014, biochar reduced water loss in warmed
                      soil by 16 $\%$ and decreased negative effects of soil
                      dryness on microbial abundances by up to 80 $\%.$ In
                      addition, the positive effect of biochar on soil moisture
                      affected canopy height of winter rapeseed in the non-warmed
                      plots in the early growth stages, although it did not change
                      the final aboveground biomass in the first year after
                      biochar application. Overall, biochar could be an
                      appropriate tool for C sequestration by improving or
                      maintaining soil fertility and productivity in temperate
                      agroecosystems under future elevated temperatures},
