- | The initial size of organic carbon pools in the soil is dependent on land use and determined by the user. The parameters (//humusc1, humusc2, humusc3, fastc1, fastc2, fastc3//) give immobile OC content of the three soil layers. The unit for these parameter values is //mg/m3//. With this information and soil layer thickness, the size of the pools in the layers are calculated. The model works with pools of the unit //kg/km2//. In addition an initial concentration of dissolved organic carbon in the soil water of different land uses may be specified (//occonc0//). The amount of DOC in the soil water is below called the //OCpool//. | + | The initial size of organic carbon pools in the soil is dependent on land use and determined by the user. The parameters (//humusc1, humusc2, humusc3, fastc1, fastc2, fastc3//) give immobile OC content of the three soil layers. In addition the initial value for organic carbon humus soil pool may be constant with depth for some soil types (parameter //humusC0st//). If this parameter is used (>0) for some soil type, the classes of this soil type will use the humusC0st value instead of the landuse dependent parameters. The unit for these parameter values is //mg/m3//. With this information and soil layer thickness, the size of the pools in the layers are calculated.
