What is biochar? A branch, a soil, a carbon cycle
An introduction to feedstocks, production and soil applications—and why context matters.
From biomass to biochar
Biochar is a carbon-rich solid formed by heating biomass with limited oxygen. Feedstock and production temperature influence its properties.
Why soils?
Used as a soil amendment, biochar may improve moisture conditions, change pH and retain some carbon for extended periods. Outcomes depend on the material and its setting.
Start with a question
What does this soil need? Define the goal before selecting a material. Biochar is not one universal recipe for every field.
