Dynamics of charcoal alteration in a tropical biome: a biochar-based study (2018)
Journal Article
Ascough, P., Bird, M., Meredith, W., Snape, C. E., Large, D., Tilston, E., …Shen, L. (2018). Dynamics of charcoal alteration in a tropical biome: a biochar-based study. Frontiers in Earth Science, 6, Article 61. https://doi.org/10.3389/feart.2018.00061

Pyrogenic carbon (PyC) is a polyaromatic residue of the incomplete combustion of biomass or fossil fuels. There is a growing recognition that PyC forms an important part of carbon budgets, due to production rates of 116–385 Tg C yr, and the size and...

The priming potential of environmentally weathered pyrogenic carbon during land-use transition to biomass crop production (2015)
Journal Article

Since land-use change (LUC) to lignocellulosic biomass crops often causes a loss of soil organic carbon (SOC), at least in the short term, this study investigated the potential for pyrogenic carbon (PyC) to ameliorate this effect. Although negative p... Read More about The priming potential of environmentally weathered pyrogenic carbon during land-use transition to biomass crop production.
