Biochar stability assessment methods: A review
TL;DR: The method details, advantages and disadvantages, along with the correlations between different methods were reviewed and discussed, and three stability assessment method categories were identified: I) biochar C structure analysis, II)Biochar oxidation resistance determination, and III) bioChar persistence evaluation by biochar incubation and mineralization rate modelling.
Journal ArticleDOI
The Pyrogenic Carbon Cycle
TL;DR: In this article, current knowledge of the production, stocks, and fluxes of PyC as well as the physical and chemical processes through which it interacts as a dynamic component of the global carbon cycle is synthesized.
Journal ArticleDOI
Influence of feedstock properties and pyrolysis conditions on biochar carbon stability as determined by hydrogen pyrolysis
TL;DR: In this paper, the stable polycyclic aromatic carbon (SPAC) fraction that is likely to be resistant to mineralization on centennial timescales has been identified, and it was shown that SPAC formation was generally 80% of TOC at temperatures above 600-700°C.
Journal ArticleDOI
Analytical pyrolysis as a tool to probe soil organic matter
TL;DR: In this paper, a review of recent developments in data acquisition and/or processing leads us to provide guidelines to select the most appropriate method and to avoid possible pitfalls, and illustrate the wide range of soil science applications and show the potential and limitations of this approach.
Journal ArticleDOI
Forest floor chemical transformations in a boreal forest fire and their correlations with temperature and heating duration
TL;DR: In this article, a high-intensity experimental wildfire was used to determine forest floor chemical transformations in a Canadian boreal forest in relation to temperature-time profiles for 18 sampling points during the fire.

Sustainable biochar to mitigate global climate change
TL;DR: The maximum sustainable technical potential of biochar to mitigate climate change is estimated, which shows that it has a larger climate-change mitigation potential than combustion of the same sustainably procured biomass for bioenergy, except when fertile soils are amended while coal is the fuel being offset.

TL;DR: In this paper, the authors conducted a comprehensive intercomparison of this type (multimethod, multilab, and multisample), focusing mainly on methods used for soil and sediment BC studies.

TL;DR: The origins, reactions and fates of molecularly-uncharacterized organic matter are relatively obscure, in large part because the rich vein of geochemical information that typically derives from detailed structural and stereochemical analysis is yet to be tapped.

Climate and human influences on global biomass burning over the past two millennia
Jennifer R. Marlon,Patrick J. Bartlein,Christopher Carcaillet,Daniel G. Gavin,Sandy P. Harrison,Philip E. Higuera,Fortunat Joos,Mitchell J. Power,Iain Colin Prentice +8 more
TL;DR: In this article, a compilation of sedimentary charcoal records spanning six continents to document trends in both natural and anthropogenic biomass burning for the past two millennia is presented, concluding that the early decline in biomass burning occurred in concert with a global cooling trend and despite a rise in the human population.
