BIOCHAR: Production and Application for Management of Soil Acidity in Northeast India

This comprehensive scientific monograph addresses soil acidity - the most widespread limiting factor for crop production across the eight states of Northeast India, where over 60% of cultivated soils have pH below 6.5. It examines biochar as a multifunctional soil amendment, synthesizing peer-reviewed research, long-term field trial data, and global meta-analyses. Topics covered include the geochemistry of acid soil formation, biochar production technologies suited to smallholder conditions, mechanisms of soil amelioration, crop-specific agronomic recommendations, economic analysis, policy frameworks, and environmental co-benefits such as carbon sequestration and greenhouse gas mitigation.
