Biochar, a stable form of carbon, is produced from pyrolysis of biological materials. It is attracting growing interest because of its potential to improve soil nutrients status, increase crop yield and sequester carbon (C) in the soil. The carbon in the biomass is subjected to easy degradation since they contain low grade carbon. But in biochar, pyrogenic carbon is formed by pyrolysis. Hence they remain in the soil for long periods. Biochar is produced from the pyrolysis of a variety of biological materials viz., Lantana camara, Dodonia viscosa, Eichornia crassipes, Prosopis juliflora, Melia dubia, Giricidia sepium and Delonix elata in pyrolysis-unit. The biochars differed much in their characteristics. Recovery of biochar was high in Prosopis whereas Eichornia showed its superiority over others in providing high pore space and water holding capacity, higher CEC, total N, P, K, S and micro nutrients. The microscopic analysis confirmed that plants species contain nutrients and it differs among the plant species. Considering the higher recovery and its distribution, resource of Prosopis can be harnessed. Due to the wide variations noticed among the plant species, characterisation of biochar from each plant species becomes a pre requisite before mass production for agriculture purpose.
