      abstract     = {Dry spells during the summer period affecting water uptake
                      and plant growth in central Europe may occur more frequently
                      in the future due to climate change. Improving the ability
                      of crops to take up water from deeper soil layers is a
                      potential strategy to secure water supply. The objective of
                      this paper is to report on the effect of different preceding
                      fodder crops on root growth and water uptake of spring wheat
                      from the subsoil. Water extraction and root length density
                      during grain filling of spring wheat were observed between
                      anthesis and maturity in six different soil depths (0-15,
                      15-45, 45-60, 60-75, 75-90 and 90-105 cm) and with four
                      different preceding crops: 1 year of fescue (Fes1Y), 2 years
                      of chicory (Chi2Y), 2 years of lucerne (Luc2Y) and 3 years
                      of chicory (Chi3Y). While there was no difference in total
                      water extraction by wheat in the four crop sequences, water
                      extraction from the deepest layer (90-105 cm) was
                      significantly higher after 2 years of lucerne (Luc2Y). This
                      was consistent with the root length densities measured in
                      the 90-105 layer, which were 82,89 and $112\%$ higher in
                      Luc2Y as compared to Fes1Y, Chi2Y and Chi3Y, respectively.
                      Results suggest that lucerne as preceding crop supports
                      deeper rooting and higher rooting density of following
                      spring wheat enhancing access to water in deeper soil layers
                      in response to prolonged dry spells. Effects facilitating
                      root penetration like improved soil structure and higher
                      nitrogen availability after lucerne are discussed. We
                      conclude that suitable crop rotations with lucerne might be
                      a cost-effective adaptation measure to overcome drought
                      stress. (C) 2011 Elsevier B.V. All rights reserved.},
