Board member and industry pioneer, Professor Stephen Joseph is the lead author of a popular DPI paper which states: “Meta-analyses show average crop yield increases of 10-42pc, with greatest response in acidic and sandy soils. As biochar ages, it is incorporated into soil aggregates, protecting the biochar carbon and promoting stabilization of rhizodeposits (organic material released from plant roots) and microbial products. Biochar carbon persists for hundreds to thousands of years.”
