      abstract     = {Agricultural production in Central Europe increasingly
                      suffers from extreme drought events. Improving root access
                      to nutrient and water resources in the subsoil below the
                      plow layer is a potential option to maintain productivity
                      during dry summers. Here, we tested a strip-wise subsoil
                      amelioration method that combines subsoil loosening with
                      organic matter incorporation into the subsoil (biowaste or
                      green waste compost) and compared it with a treatment of
                      only subsoil loosening and a non-ameliorated control. A
                      field experiment with randomized block design was conducted
                      on a Luvisol with an argic horizon (Bt), with a rotation of
                      spring barley and winter wheat. In the first two years after
                      amelioration, we monitored soil physico-chemical parameters,
                      microbial biomass, and shoot and root growth at anthesis as
                      well as harvested grain yield and quality. Subsoil loosening
                      with organic matter incorporation significantly decreased
                      soil bulk density at the depth of compost incorporation when
                      biowaste compost was used, but not when green waste compost
                      had been incorporated. Nutrient stocks, nutrient
                      availability and microbial biomass were not consistently
                      affected by the subsoil amelioration. Never- theless, the
                      incorporation of organic material, especially biowaste
                      compost, significantly increased root growth into the
                      subsoil and subsequently significantly enhanced crop
                      nutrient uptake, biomass and grain yield pro- duction. Green
                      waste compost incorporation had less pronounced effects,
                      with an increase in grain yield only in the second year
                      after amelioration. Differences in crop development could
                      not be explained by any single soil parameter, suggesting
                      that it was rather a combined effect of loosened subsoil and
                      better supply of subsoil re- sources that resulted in an
                      increase in subsoil root length density and subsequently led
                      to better crop performance.},
