This project defined the “toolkit” required to screen different biochar products and select them for plot- and field tests. The toolkit comprises a set of biochar-specific laboratory methods targeting the key functions of biochar in soil. The initial five assays quantify the long-term stability of biochar carbon, the small labile fraction, the effect of biochar on pre-existing soil carbon (priming) and agronomic benefits arising from (a) direct nutrient supply from biochar over a finite timeframe and (b) the impact of biochar on soil structural properties.
