The publication discusses biochar, a sustainable agricultural practice aimed at enhancing soil fertility and reducing carbon emissions. It explains that biochar is produced by heating biomass (plant materials) at high temperatures in low-oxygen conditions, preserving most of the carbon.

While biochar itself isn't a fertilizer, when combined with manure or compost, it can enhance soil quality and boost crop productivity. The publication highlights its importance for climate resilience by capturing carbon in the soil and reducing greenhouse gas emissions.
