Short summary

Our study aimed to disentangle the contribution of several drivers to explaining the proportion of soil carbon that can be released to CO₂ through microbial respiration. We found that boreal-forest soil chemistry is an important driver of the amount of carbon that microbes can process. Our results emphasize the need to include the effects of soil chemistry into models of carbon cycling to better anticipate the role played by boreal-forest soils in carbon-cycle–climate feedbacks.
