Abstract Carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N2O) are the three most
important greenhouse gases (GHG s), and all show large uncertainties in their atmospheric
budgets. Soils of natural and managed ecosystems play an extremely important role in
modulating their atmospheric abundance. Mechanisms underlying the exchange of these
GHG s at the soil–atmosphere interface are often assumed to be exclusively microbe‐
mediated (M‐GHG s). We argue that it is a widespread phenomenon for soil systems to …
