      abstract     = {Dissolved organic carbon (DOC) is one of the most active
                      and mobile carbon pools, and thus an important component of
                      the global carbon cycle. Previous research on DOC transport
                      in the soil and on factors controlling DOC export towards
                      the river system focused mainly on forest and wetland areas,
                      with only limited information available from agricultural
                      soils. We carried out rainfall simulations on agricultural
                      field sites to identify the effect of soil properties, field
                      characteristics and hydrological conditions on DOC export by
                      surface runoff from loamy agricultural soils. Furthermore,
                      the temporal evolution of DOC concentrations and specific UV
                      absorbance (SUVA) values in runoff water during a rainfall
                      event was monitored. Additional rainfall simulations in the
                      lab allowed to investigate the effects of drop impact, crop
                      residue incorporation and drying–rewetting of the soil on
                      DOC concentrations and SUVA values in both runoff and
                      percolation water.DOC concentrations were the highest and
                      SUVA values the lowest at the start of a rainfall event,
                      both in runoff and percolation water. Afterwards, DOC
                      concentrations diminished and SUVA values rose to steady
                      values towards the end of the experiments. Overall, rainfall
                      conditions prior to the experiment showed to be a major
                      control on DOC concentrations and quality in runoff water
                      from agricultural fields. Smaller rainfall depths before the
                      experiment and lower initial soil moisture content led to
                      high concentrations of low aromatic DOC in the runoff water.
                      This drying–rewetting effect on DOC concentrations and
                      quality was also observed in the lab for percolation water.
                      For the range of considered soil types, only a limited
                      effect of soil and field characteristics on DOC
                      concentrations and quality in runoff was observed. The
                      effect of reduced tillage on DOC concentrations in surface
                      runoff was ambiguous, with effects differing between
                      experimental field sites.},
