Biochar is a carbon-rich form of charcoal that can be applied to agricultural land to help with environmental management. It is formed by heating biomass in low-oxygen conditions and helps retain water in soil, releasing it to crops during drought and increasing yields more than fertilizer alone can. The region produces enough agricultural waste annually to produce over 120,000 tonnes of biochar, enough to treat 3,000 hectares of land per year and address local yield losses from lack of water and poor soil quality.
