Abstract
Biochar is a kind of charcoal used for soil improvement and it is produced by pyrolysis of biomass under low or anaerobic conditions. It has the potential to mitigate climate change, via carbon sequestration, decrease soil acidity and increase agricultural productivity. Historically it is known that the Amazonians used biochar to enhance soil productivity by smoldering agricultural wastes. Desk reviewed of articles of soil amended biochar and some attributes which enhance crop development and the economic benefits derived from its use in agriculture were critically analysed. A meta-analysis using twenty-seven (27) articles reveal that the temperature at which pyrolysis is done is a major contributing factor towards the intended use of the biochar. For the purpose of crop yield, a temperature of 5500C is recommended based on the regression results. It is recommended that an in-depth study should be done for particular crops taking into consideration the soil and the geographical location of such crops for yield enhancement.
