Rapid loss of complex polymers and pyrogenic carbon in subsoils under whole-soil warming

HIGHLIGHTS

• who: Cyrill U. Zosso from the derived from incomplete combustion processes However, recent findings challenge the millennial persistence of PyC in soils, showing that PyC turns over on a timescale of centuries13-with a mean residence time about, ., times that of bulk SOC11. The wood-derived polymer lignin, which is made up of phenolic structures, has been described and modelled as part of the recalcitrant carbon pool, but it too has been shown to readily degrade in soils12, . Finally, plant-derived hydrolysable lipids cutin, derived from cuticular tissues of vascular plants19, and suberin, derived from woody tissues20 . . .
