Short summary

Updating the Yasso07 soil C model's dependency on decomposition with a hump-shaped Ricker moisture function improved modelled soil organic C (SOC) stocks in a catena of mineral and organic soils in boreal forest. The Ricker function, set to peak at a rate of 1 and calibrated against SOC and CO₂ data using a Bayesian approach, showed a maximum in well-drained soils. Using SOC and CO₂ data together with the moisture only from the topsoil humus was crucial for accurate model estimates.
