Biochar is a high carbon-containing product obtained from the thermal decomposition or pyrolysis of organic biomass. Biochar is known for its significance in soil amendment by improving soil fertility, water retention, nutrient cycling, and carbon sequestration. It may modify symbiotic relationships between plants and microbes near the root, thereby enhancing microbial activity and overall soil health. Additionally, biochar’s long-lasting carbon sequestration potential contributes to climate change mitigation efforts. In agricultural settings, biochar can significantly increase crop yields by improving nutrient availability and soil fertility. The use of biochar can reduce the application for synthetic fertilizers and pesticides, leading to more sustainable agricultural practices. Biochar’s impact on soil health is not limited to conventional agriculture. Due to some important characteristics like porosity, uneven expanded surfaces and chemical makeup, biochar considered as an efficient soil amendment substance. The functions of biochar include improvements in Physical and chemical characteristic of soil. It facilitates macro-aggregation of soil, thus reducing soil erosion and enhancing soil stability. Soil carbon sequestration is also achieved via the carbon content of biochar. While biochar has shown immense potential for enhancing soil health and sustainability, its effects can vary depending on soil type, production method, and application rate. However, further investigation is required to understand these variations and optimize biochar application for specific soil conditions and farming practices. Future studies should focus on refining biochar production methods, understanding its effects on different soil types, and integrating it into diverse agricultural systems to maximize its potential for sustainable soil management.
