Abstract: Biochar may be added to soils with the goal to improve the soil properties and relocate an amount of conventional fossil fuel based fertilizers, and sequester carbon. Biochar stability is critical to quantifying the impact of biochar amendments on net greenhouse gas (GHG) emissions to the atmosphere, it is not sufficient. Biochar production and incorporation in soil must play a role in climate change mitigation. The need for further clarity on optimizing biochar application to various crop yields is necessary if it is to gain widespread acceptance as a soil amendment. There is urgent need to intensify agricultural production to secure food supply for the increasing population especially in developing country like India of the tropics. But, the organic matter is mineralized at a faster rate due to high temperature (32-44 ⁰C) throughout the year except in winter season. Biochar proponents have placed on biochar stability in soil and it also includes increased soil fertility and water holding capacity, increased crop production, and remediation of contaminated soils. The organic matter is important for sustainable agriculture in the soils. The large quantities of biomass residues, which should be considered as precious residues, are disposed or burned, and reasons unaffordable ecological issues and notable soil degradation. Application of green waste biochar improves soil physical properties of this hard setting soil in terms of reduction tinsel strength and increases in field capacity. The biochar have potential to feasibly and sustainably sequester/offset over 1 Pg of CO₂-carbon equivalents annually. Current carbon market incentives are not sufficient to rapidly increase or maximize the initiation and development of biochar implementation.
