Short summary
Soil CO2 emissions are a major determinant of the carbon (C) cycle and its interactions with climate. Here, we show that soil CO2 emissions have two origins: (1) the well-known microbial cell respiration and (2) an extracellular oxidative metabolism (EXOMET) carried out by soil-stabilized enzymes and mineral catalysts. These two metabolisms have distinct C isotope signatures, allowing their detection in soil CO2 emissions.
