QUALITY EVALUATION OF BIOCHAR FROM DIFFERENT AGRICULTURAL BIOMASS

Biochar, one of the co products of pyrolysis unit , is a potential soil amendment that sequestrates large amount of carbon which helps in increasing the soil fertility. And also application of biochar to t he soil reduces compaction, increase water holding capacity, nutrient availability, enhance biological activity, increase crop yields and reduce nitrous oxide emissions. In this research, bhendi and brinjal stalks are used to produce biochar by using pyrolysis. The nutritive content in biochar is analysed by proximate and ultimate analysis. As the result of proximate analysis, the nutritive contents such as moisture content, ash content, fixed carbon and volatile matter has recorded higher in bhendi stalks whereas in ultimate analysis such as carbon, nitrogen, hydrogen and sulfur, brinjal stalks has recorded a higher value. As the result, applications of biochars of bhendi stalks and brinjal stalks will improves the soil nutritive content than the biomass application KEYWORDS: Biochar, bhendi, brinjal, proximate analysis, ultimate analysis, soil fertility.
