In 2012, together with our partner Africa Wood Grow, we started growing sweet sorghum on biochar-enriched soils near Kathome village in West Kenya. Waste biomass derived from trees and sorghum plants are turned into biochar, which is then added to the soil as an improvement agent. The results of this project have demonstrated the beneficial characteristics of biochar as a water and nutrition retention agent. This resulted in substantial increases in crop yield. Local farmers have shown great enthusiasm for using biochar as a natural method to enrich their degraded soils.
