biocharMycorrhizal responses to biochar in soil – concepts and mechanismsCategory: Biochar - Documnet Type: Book ReviewExperiments suggest that biomass-derived black carbon (biochar) affects microbial populations and soil biogeochemistry. Both biochar and mycorrhizal associations, ubiquitous symbioses in terrestrial ecosystems, are potentially important in various... More» Author: Daniel D. Warnock, Johannes Lehmann, Thomas W. Kuyper, Matthias C. Rillig - submitted on Fri, 11/07/2008 - 00:39. Biochar and bioenergy production for climate change mitigationCategory: Biochar - Documnet Type: Technical ReportThe world will increasingly depend on renewable energy with low or zero net greenhouse gas (GHG) emissions. This paper explores how science and the economic ‘rules of the game’ might realize the potential for the pyrolysis co-production of biochar and bio-oil to mitigate net GHG emissions while achieving other economic and environmental benefits....

Bio-Char Sequestration in Terrestrial Ecosystems - A ReviewCategory: Biochar - Documnet Type: Technical ReportThe application of bio-char (charcoal or biomass-derived black carbon (C)) to soil is proposed as a novel approach to establish a significant, long-term, sink for atmospheric carbon dioxide in terrestrial ecosystems....

Biochar as a soil amendment: A review of the environmental implications.Category: Biochar - Documnet Type: Technical ReportThe term 'biochar' refers to black carbon formed by the pyrolysis of biomass i.e. by heating biomass in an oxygen-free or low oxygen environment such that it does not (or only partially) combusts. Traditional charcoal is one example of biochar produced from wood. The term 'biochar' is much broader than this however, encompassing black carbon produced from any biomass feedstock....
