Coal for Soil Remediation: A Game-Changer?

This article explores soil degradation and its impact on food security and climate change. Traditional agricultural practices have led to severe soil erosion and degradation. The author introduces biochar, a soil amendment that improves soil fertility, increases crop yields, and enhances carbon sequestration. However, biochar is expensive. The article highlights a cheaper alternative: coal char, produced from pyrolyzed coal. Preliminary studies suggest that coal char offers similar soil improvement benefits to biochar at a fraction of the cost (less than one-tenth). This presents a potential game-changer for large-scale soil remediation, but further research is needed to assess its long-term impacts and environmental risks.
