Know day In most parts of the world, soil acidity has become a significant problem to agricultural production. The high buildup of H+ ions relative to OH- ions in the soil solution results in the acidity of the soil. Understanding the function of biochar in reducing soil acidity and enhancing crop yield was the main goal of this review. Biochar is a carbon rich substances resulting from the pyrolysis of organic material, it accumulate carbon for long time, ameliorates degraded soil and lowering soil acidity for better crop production. Additionally, using biochar as a soil amendment increases agricultural yield by boosting soil's ability to hold water, making nutrients available to plants through cation exchange capacity, adsorbing nutrients, creating favorable conditions for soil microorganisms, and enhancing carbon sequestration. Generally, soil management by biochar under acidic soil increase nutrient availability like available phosphorous, soil pH, cation exchange capacity, crop yields and reduce hazard of crop failure. However the influence of biochar application on crop production depending on soil type, soil condition, nature and rate of biochar used..
