Summary
Soil fertility is declining due to the increased use of synthetic fertilizers and monocropping practices. Intensive farming, mining, and heavy metal contamination have caused numerous adverse effects on soils. To boost crop growth and keep soil fertile, it’s vital to protect soil’s physical, chemical, and biological makeup by ensuring sufficient organic content. Biochar is gaining recognition as a sustainable soil enhancer across various fields, including agriculture, environmental science, and energy. This article provides a comprehensive overview of biochar, covering its production, characterization, and impact on soil application. The review concludes that biochar application decreases soil bulk density, reduces soil N2O emissions, and mitigates soil salinization by increasing soil poro
