      abstract     = {Modelling of soil respiration plays an important role in
                      the prediction of climate change. Soil respiration is
                      usually divided in a fraction originating from root
                      respiration and a heterotrophic fraction originating from
                      microbial decomposition of soil organic carbon. This paper
                      reports on the coupling of an one-dimensional water, heat
                      and CO2 flux model (SOILCO2) with a pool concept of carbon
                      turnover (RothC) for the prediction of soil heterotrophic
                      respiration. In order to test this coupled model, it was
                      applied to a bare soil experimental plot located in Bornim,
                      Germany. Soil temperature and soil water content
                      measurements were used for comparison with the respective
                      model predictions. An 8 years data set Of CO2 efflux
                      measurements, covering a broad range of atmospheric
                      conditions, was used to evaluate the model. In a first step
                      we quantified the improvement of the CO2 efflux prediction
                      due to the coupling of the flux model with a pool concept of
                      carbon turnover. The humus pool decomposition rate constant
                      and its soil water content dependent reduction were derived
                      from the first 5 years Of CO2 efflux measurements using
                      inverse modelling. The following 3 years of measurements
                      were used to validate the model. The overall model
                      performance Of CO2 efflux predictions was acceptable with
                      the measured and simulated mean daily respiration being
                      0.861 and 0.868 g C m(-2) d(-1), respectively, and a mean
                      absolute difference between modelled and measured rates of
                      0.21 g C m(-2) d(-1). The inverse estimation of the humus
                      decomposition rate constant resulted in a value of 0.04
                      year(-1), which is higher than the default value in RothC.
                      This is attributed to the agricultural practice during the
                      experiment. (c) 2008 Elsevier B.V. All rights reserved.},
