A new global study introduces a process-based model to predict how biochar affects crop yields and soil carbon storage. By analyzing data from 48 field sites, researchers found that biochar's effectiveness varies by region, performing best in tropical and temperate climates with medium-textured soils. The research highlights a trade-off in application rates. Moderate amounts of biochar typically optimize crop productivity, while higher application rates are more effective for long-term carbon sequestration and reducing greenhouse gas emissions.
