Biochar is pyrogenous, organic material synthesized through pyrolysis of different biomass (plant or animal). Main biochar applications include: pollution remediation due to high CEC and specific surface area, soil fertility improvement and carbon sequestration due to carbon and ash content etc. Pyrolysis temperature and biomass type used to prepare biochar affect the physicochemical characteristics of produced biochar, and when applied as soil amendment shows a range of results. In this study, Different biochars were prepared from different biomass types, namely Corn cobs (Zea mays), eucalyptus tree branches (Eucalyptus globulus), potato peels (Solanum tuberosum) at and sorghum tassels (Sorghum bicolor) at temperature range of 6000C-7000C. However, eight biochars were prepared where four biochars were prepared in open environment and other in furnace. The impact of temperature and biomass type on variability of physicochemical characteristics of obtained biochars were evaluated through measuring pH, electrical conductivity(EC), total dissolved solids and moisture content and Moreover, the physicochemical properties of biochar determine application of this biomaterial as an additive to improve soil fertility. The objective of study was to evaluate the impact of biomass type and pyrolysis temperature on physicochemical properties of biochar on soil fertility. The results of moisture content of different biomass types, namely Corn cobs (Zea mays), eucalyptus tree branches (Eucalyptus globulus), potato peels (solanum tuberosum) and sorghum tassels (Sorghum bicolor) are 59.97±0.03%,39.87±0.03%,79.65±0.04% and 23.75±0.03%respectively. The pH in furnace was :9.90, 10.03, 9.95, 10.03 respectively; EC :1850, 1248, 4660, 5400; TDS:989, 651, 2630, 3110 respectively and in open environment was :11.20, 11.06, 10.04, 11.92; 2640, 2630, 7590, 5720; 1401, 1407, 4260, 320 in pH, EC, TDS respectively.All results reported with negative values are not detected in samples (ND)
