Short summary
Weathering rates in forest soils are important for sustainable forestry but cannot be measured. In this paper, we have modelled weathering with the commonly used PROFILE model as well as with the dynamic model ForSAFE, better suited to a changing climate with changing human activities but never before tested for weathering calculations. We show that ForSAFE gives comparable weathering rates to PROFILE and that it shows the variation in weathering with time and works well for scenario modelling.
