      abstract     = {Future crop production will be affected by climatic
                      changes. In several regions, the projected changes in total
                      rainfall and seasonal rainfall patterns will lead to lower
                      soil water storage (SWS) which in turn affects crop water
                      uptake, crop yield, water use efficiency, grain quality and
                      groundwater recharge. Effects of climate change on those
                      variables depend on the soil properties and were often
                      estimated based on model simulations. The objective of this
                      study was to investigate the response of key variables in
                      four different soils and for two different climates in
                      Germany with different aridity index: 1.09 for the wetter
                      (range: 0.82 to 1.29) and 1.57 for the drier climate (range:
                      1.19 to 1.77), by using high-precision weighable lysimeters.
                      According to a “space-for-time” concept, intact soil
                      monoliths that were moved to sites with contrasting climatic
                      conditions have been monitored from April 2011 until
                      December 2018.Evapotranspiration was lower for the same soil
                      under the relatively drier climate whereas crop yield was
                      significantly higher, without affecting grain quality.
                      Especially "non-productive" water losses (evapotranspiration
                      out of the main growing period) were lower which led to a
                      more efficient crop water use in the drier climate. A
                      characteristic decrease of the SWS for soils with a finer
                      texture was observed after a longer drought period under a
                      drier climate. The reduced SWS after the drought remained
                      until the end of the observation period which demonstrates
                      carry-over of drought from one growing season to another and
                      the overall long term effects of single drought events. In
                      the relatively drier climate, water flow at the soil profile
                      bottom showed a small net upward flux over the entire
                      monitoring period as compared to downward fluxes (ground
                      water recharge) or drainage in the relatively wetter climate
                      and larger recharge rates in the coarser- as compared to
                      finer-textured soils. The large variability of recharge from
                      year to year and the long lasting effects of drought periods
                      on SWS imply that long term monitoring of soil water balance
                      components is necessary to obtain representative estimates.
                      Results confirmed a more efficient crop water use under less
                      optimal soil moisture conditions. Long-term effects of
                      changing climatic conditions on the SWS and ecosystem
                      productivity should be considered when trying to develop
                      adaptation strategies in the agricultural sector.},
