2.2. Biogeochemical characterisation of biochar
2.2.1. The purpose of biogeochemical characterisation
Although commercial biochar products are being developed for use in soil, credit for carbon
storage will require predictable levels of stability and the ability to verify actual rates of
degradation through quantitative soil analysis (Ogawa et al., 2006; Matthews, 2008).
Identifying the characteristics that determine the stability of biochar will enable its properties
to be optimised and standardised in production. Techniques to unambiguously detect and
