Biochar Boosts Crop Yields by 10-150% and Sequesters up to 1900 Metric Tons of CO2​ Annually

In a comprehensive review published in Frontiers in Sustainable Food Systems, Sazada Siddiqui explores the multifaceted environmental potential of biochar, detailing its production, diverse applications, and inherent limitations. The article, “Unlocking the environmental potential of biochar: production, applications, and limitations,” highlights biochar’s role in addressing critical global challenges like soil degradation and climate change.

Soil degradation, driven by factors such as prolonged cultivation, acidification, erosion, and the overuse of chemical fertilizers, poses a severe threat to global food security. The Green Revolution, while boosting crop yields, inadvertently contributed to a decline in soil fertility and quality. Biochar, a renewable and carbon-rich material produced through the pyrolysis of biomass under limited oxygen, emerges as a promising solution. It is characterized by high specific surface area, low bulk density, and strong adsorption capacity, making it a valuable tool for soil fertility management, crop yield improvement, and greenhouse gas emission reduction.
