Agriculture Biochar Production: Applications and Challenges for Crop Improvement

The rapid growth of the global population and increasing environmental stress have intensified the need for sustainable agricultural solutions. Biochar, a carbon-rich material produced through the pyrolysis of biomass under limited oxygen conditions, has shown promising potential in enhancing soil health. Its application improves soil structure, nutrient availability, water retention, and microbial activity, while also serving as a long-term carbon sink. Biochar can limit the mobility of pesticides and heavy metals, reducing environmental risks, and can also be utilized in composting, livestock feed, and greenhouse gas mitigation. The efficiency of biochar depends on factors such as feedstock type, pyrolysis temperature, soil characteristics, and application rate. Prospects highlight biochar’s role in sustainable farming and climate change mitigation; however, challenges remain in optimizing production processes, tailoring biochar properties for specific soils, and ensuring economic feasibility for large-scale adoption
