Improving crop yield and storing carbon. Biochar in conservation farming in Zambia. End report phase 1.

The main aim of the project is to investigate the potential of organic waste biochar to sequester carbon and improve the fertility of weathered, sandy and/or acidic Zambian soils. Biochar amendment is exclusively combined with Conservation Farming (CF). In CF only10-12% of the land is tilled. Therefore CF and biochar are a favourable combination, since less biochar is needed to obtain the same effectiveness as with conventional tillage.
