01 Jun Biochar – The new black gold for agricultre
बायोचर - कृषि के लिए नया काला सोना Agricultural waste is usually handled as a liability, often because the means to transform it into an asset is lacking. These residues are either partially utilized or un-utilized due to various constraints. Among the cereal residues, rice and wheat straws are the dominant and the easiest way to clear the field is burning these in the field itself. By realizing those problems, some previous researchers try to use the more resistant organic matter such as biochar. Biochar has great importance in improving soil fertility and it could act as a soil amendment to increase crop yield and plant growth by supplying and retaining nutrients than other organic matter such as leaf litter, compost or manure. Conversion of biowaste to biochar is a potential tool for carbon sequestration and reducing GHG emission. Biochar is a fine-grained, carbon-rich, porous product remaining after plant biomass has been subjected to thermo-chemical conversion process at high temperatures with little or no oxygen. The central quality of biochar that makes it attractive as a soil amendment is its highly porous structure, potentially responsible for improved water retention and increased soil surface area. Because of its aromatic structure dominated by aromatic carbon, biochar has been found to be biochemically recalcitrant compared to uncharred, parent organic matter and...
