A proof-of-concept tool exploring how pool-specific carbon dynamics affect the durability of SOC gains over time. Applies mean residence time frameworks to the POC/MAOC accrual split — illustrating how measurement assumptions shape permanence outcomes under the tonne-year approach.
Overlays stoichiometric microbial carbon use efficiency (CUE) predictions against global soil carbon registry projects. Maps project sites against the Rh threshold beyond which CUE saturates — identifying where microbial pathways are a credible driver of SOC gains versus where mineral stabilisation dominates.
