Pyrogenic carbon sequestration in Australian soils. Pyrogenic Carbon ('charcoal') is a poorly understood component of the global carbon cycle, important because it is resistant to degradation and hence has potential soil carbon sequestration benefits. This project applies a new technique (hydrogen pyrolysis), in combination with spectroscopic techniques, to quantify charcoal in a pan-Australian soil sample set, collected using uniform stratified sampling and preparation protocols.

Pyrogenic Carbon ('charcoal') is a poorly understood component of the global carbon cycle, important because it is resistant to degradation and hence has potential soil carbon sequestration benefits. This project applies a new technique (hydrogen pyrolysis), in combination with spectroscopic techniques, to quantify charcoal in a pan-Australian soil sample set, collected using uniform stratified sampling and preparation protocols. This will enable the mapping of soil charcoal stocks in relation to environmental and soil variables across Australia. The results will enable understanding of the controls on charcoal sequestration potential in Australian soils and contribute to efforts to quantify soil charcoal stocks and dynamics globally.Read moreRead less
