- | Turnover of humusC is a sink for humusC and a source of OC in all soil layers (k = 1.3). The loss of humusC does not all go to the TOC, ut a proportion (parameter //minc//) is mineralized. Turnover (//transhC//, //mg/m2/d//) depends on a general parameter (//kho//), temperature function (//tempfcn//), humidity function (//smfcn//) and the pool of humusC (//humusC//). | + | Turnover of humusC is a sink for humusC and a source of OC in all soil layers (k = 1.3).

The soil moisture function and temperature function are the general functions described for soil processes. Percolation uses the coefficients for soil moisture function, not the parameters as the transformations. The parameter //par// in the equation is called //kcgwreg// for regional groundwater flow formation and //koc// for percolation between soil layers. Both are general parameters. | The soil moisture function and temperature function are the general functions described for soil processes.
