Abstract

An investigation entitled ‘Production characterisation and quality assessment of biochar’ was conducted to assess the effect of production methods and materials used on the character of biochar at Plant Propagation & Nursery Management Unit (PPNMU), Vellanikkara, Thrissur during 2014-15. Woody wild growth, coconut petiole and herbal waste residues left after composting were the three materials used for biochar production. Biochar was produced using heap and drum methods. Biochar was characterised by physical and chemical distinctiveness. Methods of production and materials used had significant influence on the characteristics of biochar. Drum method gave higher biochar recovery, high porosity and water holding capacity compared to heap method. Porosity, water holding capacity and carbon content were higher in biochar produced from woody wild growth. All biochars showed alkaline pH with the highest pH in coconut petiole biochar, An overall increase in NPK content was noticed in biochar compared to the feedstock materials.align="justify">
