Carbon pathways in soil: unraveled by 13C natural abundance

Soil organic matter (SOM) escapes microbial and enzymatic decomposition by stabilizing on clays and iron- and aluminum (oxyhydro)oxides, or by being trapped within aggregates. We analyzed the importance of these stabilization mechanisms based on 13C natural discrimination within SOM pools and genera...
