Black (pyrogenic) carbon: a synthesis of current knowledge and uncertainties with special consideration of boreal regions

CM Preston, MWI Schmidt - Biogeosciences, 2006 - bg.copernicus.org
The carbon (C) cycle in boreal regions is strongly influenced by fire, which converts biomass
and detrital C mainly to gaseous forms (CO 2 and smaller proportions of CO and CH 4), and …

Reconstructing past fire regimes: methods, applications, and relevance to fire management and conservation

Biochar particle size, shape, and porosity act together to influence soil water properties

Z Liu, B Dugan, CA Masiello, HM Gonnermann - Plos one, 2017 - journals.plos.org
Many studies report that, under some circumstances, amending soil with biochar can
improve field capacity and plant-available water. However, little is known about the …

[PDF][PDF] Review of the stability of biochar in soils: predictability of O: C molar ratios

KA Spokas - 2010 - researchgate.net

Fire-derived organic carbon in soil turns over on a centennial scale

N Singh, S Abiven, MS Torn, MWI Schmidt - Biogeosciences, 2012 - bg.copernicus.org
Pyrogenic carbon (PyC), the residue of an incomplete combustion of biomass, is considered
as a carbon (C) sink due to its assumed stability in soil. PyC turnover time estimated using …
