Some researcher has proven that biochar can hold gasses which will reduce nitrous
oxide and carbon dioxide emissions by 50–80%. However NO 2 is an important
greenhouse gas and has 310 times more potent than CO 2 (Schmidt 2012; Karhu
et al. 2011). These are some of beneficial effect of biochar on crops and medical
plants (Fig. 9.1).
9.4 Composition of Biochar
Most of the feedstock used in biochar production is obtained from farm yield wastes,
such as grass and corn stover, and the diseased trees which were removed by the
Forestry department. In addition, some other feed stocks used for biochar synthesis
are as follows: livestock and poultry wastes, wood processing residues, wastewater,
municipal solid wastes, and biosolids (Lehmann and Joseph 2015; Duku et al. 2011).
