Short summary
Throughfall and litter leachate DOC fluxes amounted to 6.81 and 7.23 % of the net ecosystem exchange, respectively. The surface soil was a sink of above water transported DOC. The analysis of 13° C hydrological water DOC and soil, leaf and litter indicated that DOC is transformed in the surface soil. Soil respiration is more dependent on water transported DOC flux than soil-water content (at 0–20 cm), and most sensitive to soil-water DOC flux (at 0–20 cm) compared to soil temperature.
