      abstract     = {The impact of heterogeneous soil compaction in combination
                      with nutrient availability on root system architecture and
                      root growth dynamics has scarcely been investigated. We
                      quantified changes of barley (Hordeum vulgare L.) root and
                      shoot growth during the first 3 weeks of growth in a
                      controlled-environment chamber. Vertically divided
                      split-root rhizotrons were filled either uniformly with
                      loose or compacted peat, or heterogeneously with loose peat
                      in one compartment and compacted peat in the other. We
                      investigated the following questions. (a) Can growth
                      processes affected by soil compaction be mimicked in our
                      system? (b) Do plants show compensatory growth effects when
                      exposed to heterogeneous soil compaction? (c) Does localised
                      fertiliser application affect root systems’ responses to
                      compaction? We observed compensatory effects regarding root
                      system architecture and root growth dynamics due to
                      vertically heterogeneous soil compaction. Roots grew deeper
                      and lateral roots emerged earlier in the loose compartment
                      of the split-root treatment compared with uniform
                      treatments. When fertiliser was applied only via the
                      compacted compartment in the split-root treatment, more
                      lateral roots were initiated in the compacted compartment
                      and lateral root formation started a few days earlier than
                      in the uniform treatments. Consequently, the first days
                      after exposure to heterogeneous soil conditions are critical
                      for the analysis of underlying physiological responses.},
