      abstract     = {In a controlled rhizotrone experiment, stable isotope
                      tracers of Mg, Ca and K were applied directly to the
                      rhizosphere of an oak seedling using a 2D-array of micro
                      ceramic cups. Before starting isotope application the oak
                      root induced a significant reduction of K+, Ca2+, Mg2+ and
                      NO3- in the soil solution of the rhizosphere, as well as an
                      increase of Al3+. The effect of adding stable isotopes in
                      the soil ( soil solution and exchangeable cations) was
                      mainly restricted to a distance of about 1 cm from the point
                      of application. All stable isotopes were taken up by the oak
                      seedling, especially Ca which according to leaf analysis was
                      in the range of insufficiency. As expected, Ca showed low
                      mobility in the phloem, resulting in a low percentage of
                      label in the root tip as compared to other root segments.
                      Our experiment proved, that in-situ application is an easy
                      to handle tool for carrying out tracer studies in real
                      soil.},
