UKBRC is establishing an appropriate "minimum" standard for biochar alongside a set of assays to quantify positive attributes (see Biochar Screening Toolkit). The minimum standard ensures that applications to soil are safe, in particular addressing risk arising from any toxic elements present (along the same principle as for compost or sewage sludge) This is being explored in collaboration with the relevant regulatory authorities and industries. Positive attributes are important since they will add value to biochar added to soil and need to be assured. These include the stability of the carbon in biochar (relevant to possible carbon offsetting activties) and the supply of crop-relevant nutrients to the soil.
