Biochar Fund has reported extremely encouraging first results from its field trials in South West Cameroon. Working with small groups of subsistence farmers around the town of Kumba, the Fund set up and managed a large-scale experiment to assess whether maize (corn) yields were improved by the addition of biochar to the soil. The biochar was made from local agricultural wastes and tree thinnings. The data from the trials strongly suggests that biochar adds greatly to food production. Some areas showed yield improvements of more than 250% over the control plots. The areas dosed with biochar also showed substantially increased production of crop biomass, including roots, stalks, and leaves.
