Biochar is a stable carbon (C) compound created when biomass (feedstock) is heated to temperatures between 300 and 1000ºC, under low (preferably zero) oxygen concentrations. Biochar, due to its aromatic structure and long mean residence time in soil (more than 100 years) has the potential for long-term carbon sequestration in the soil. Biochar can be produced from a variety of biomass feed stocks, but is generally designated as biochar only if it produces a useable co-product for soil improvement. The efficiency and effectiveness of the process of its creation and use can vary and the specific biomass sources used can affect the characterization and stability of the biochar. A study was conducted to determine the prosopis biochar characterisation and soil fertility of maize in Alfisols of Thoothukudi district. A randomized block design was employed with fifteen treatments (two levels of biochar and two levels of recommended dose of fertiliser with biofertiliser (Azophos 4 pockets ha-1)) and two replications. Application of biochar with inorganic fertilisers and biofertiliser increased the soil fertility of maize in Alfisols. The combined application of biochar with 100% recommended dose of fertiliser and biofertiliser increased the nutrient use efficiency and soil fertility status of the soil.
