Abstract: The performances of five carbon (C) and nitrogen (N) cycling models (FLDM, CENTURY, SOMM, DOCDOM and CANDY) were compared for their ability to quantify mass and N remaining in 10g leaf-litterbags across the wide range of litter types and sites of the Canadian Intersite Decomposition Experiment (CIDET), over a 6-year period. These models differ in their structure and assumptions, number of compartments, predictor variables and coefficients. Calibrated model outputs displayed similar but not identical trends for mass and N remaining, but differed substantially in mass and N contents per model-defined compartments. The quality of fit between model calculations and data varied as follows: FLDM>CENTURY>DOCMOD>CANDY>SOMM for mass remaining (0.73DOCMOD>CENTURY>SOMM>CANDY for the changing N concentrations inside the bags (0.40Keywords: Organic matter decomposition; Nitrogen mineralization; Climate; Forest litter type; Modeling (search for similar items in EconPapers)
