Biochar was made from pigeonpea and cotton residues using a portable drum method. The biochar had high pH levels, making it good for reducing soil acidity. It also had low bulk density, which helps with soil aeration and water retention. The biochar contained plant nutrients and could help improve soil fertility. The carbon recovery from the biochar production process showed potential for carbon sequestration, which is important for addressing climate change. Overall, the biochar produced using this method has great qualities for improving soil when used by small farmers.
