1600: Biochar

This paper is taken from the IBERS publication, “Biochar for sustainable soil, agriculture and energy systems” by Edward Hodgson, Amy Bevan and Kerrie Farrar

Year of Publication2012

Biochar is a black, carbon-rich, material produced by thermally treating biomass materials in zero- or limited-oxygen conditions using a process called pyrolysis. It can be produced from a wide range of different materials, not just wood. When applied to land, biochar acts as a carbon sink but also as a soil improver by increasing the water and nutrient-holding capacity of the soil. It may also be effective in reducing greenhouse gas emissions from the soil.
