The article reviews the agronomic impacts of biochar, emphasizing its potential to revitalize degraded soils, enhance carbon sequestration, and improve agricultural productivity. Biochar, a form of black carbon produced through pyrolysis of biomass, is not a single entity but a range of black carbon forms with varying properties due to production methods and post-production factors. While some studies report yield increases after biochar application, others show negative or no significant effects. Hardwood biochar produced by traditional methods has shown the most consistent yield increases. The economic viability of biochar is tied to the duration of its agronomic benefits, and further research is needed to determine optimal conditions for its economic and agronomic benefits. The article also discusses the potential specialized markets for biochar, such as slow-release fertilizers, contaminated site cleanup, and industrial applications, which could improve its economic feasibility. Despite the challenges, the authors emphasize the importance of continued research to optimize biochar production and its use in improving soil quality and food security.The article reviews the agronomic impacts of biochar, emphasizing its potential to revitalize degraded soils, enhance carbon sequestration, and improve agricultural productivity.
