Comparison of pyrogenic carbon abundance in coarse-textured soil by hydrogen pyrolysis, NMR and dichromate oxidation and MIR-PLSR Open
Soil pyrogenic carbon (PyC) is of considerable significance to the global carbon cycle as a carbon pool which is resistant to mineralization and thus offers opportunities to facilitate net carbon sequestration. Quantifying the size and dyn…

The radiocarbon age of soil carbon is a function of vertical transport rates Open
The radiocarbon content of soil organic carbon (C) is largely assumed to be a reflection of the carbon’s reactivity and a metric of its potential response to either warming or CO2 enhanced soil C inputs. Here we show that advective vertica…

Impact of fire return interval on pyrogenic carbon stocks in a tropical savanna, North Queensland, Australia Open
Background Indigenous fire management in northern Australian savannas (beginning at least 11,000 years ago) involved frequent, small, cool, early dry season fires. This fire regime changed after European arrival in the late 1700s to unmana…
