Short summary
We tested how soil carbon models predict carbon storage and respiration using soil incubation data. We compared 2-pool models based on particulate and mineral-associated carbon with 3-pool models that also include faster-cycling carbon. 3-pool models performed better because they captured carbon dynamics operating at different timescales. We then simulated alternative model structures and found that transfer rates into the most persistent pool were the main control on overall carbon persistence.
