                      funded by the Deutsche Forschungsgemeinschaft within the
                      scope of the Biodiversity Research Group (FOR 456) with
                      support from the Friedrich Schiller University, Jena and the
                      Max Planck Society. We gratefully acknowledge all the people
                      that were involved in the planning and set-up of the

      abstract     = {We investigated the fate of root and litter derived carbon
                      in soil organic matter and dissolved organic matter in soil
                      profiles, in order to explain mechanisms of short-term soil
                      carbon storage. A time series of soil and soil solution
                      samples was investigated at the field site of The Jena
                      Experiment between 2002 and 2004. In addition to the main
                      experiment with C3 plants, a C4 species (Amaranthus
                      retroflexus L) naturally labeled with C-13 was grown on an
                      extra plot. Changes in organic carbon concentration in soil
                      and soil solution were combined with stable isotope
                      measurements to follow the fate of plant carbon into the
                      soil and soil solution. A split plot design with plant
                      litter removal versus double litter input simulated
                      differences in biomass input. After 2 years, the no litter
                      and double litter treatment, respectively, showed an
                      increase of 381 g C m(-2) and 263 g C m(-2) to 20 cm depth,
                      while 71 g C m(-2) and 393 g C m(-2) were lost between 20
                      and 30 cm depth. The isotopic label in the top 5 cm
                      indicated that 115 g C m-2 and 156 g C m(-2) of soil organic
                      carbon were derived from C4 plant material on the no litter
                      and the double litter treatment, respectively. Without
                      litter, this equals the total amount of 97 g C m(-2) that
                      was newly stored in the same soil depth, whereas with double
                      litter this clearly exceeded the stored amount of 75 g C
                      m(-2). Our results indicate that litter input resulted in
                      lower carbon storage and larger carbon losses and
                      consequently accelerated turnover of soil organic carbon.
                      Isotopic evidence showed that inherited soil organic carbon
                      was replaced by fresh plant carbon near the soil surface.
                      Our results suggest that primarily carbon released from soil
                      organic matter, not newly introduced plant organic matter,
                      was transported in the soil solution. However, the total
                      flow of dissolved organic carbon was not sufficient to
                      explain the observed carbon storage in deeper soil layers,
                      and the existence of additional carbon uptake mechanisms is
                      discussed. (C) 2008 Elsevier Ltd. All rights reserved.},
