Introduction of biochar and its impacts on soil: An Overview
Author(s): Ghulam Murtaza and Rose Mary
Abstract: Biochar is a type of black carbon produced from a carbonaceous material through the application of heat or chemicals (Lehmann, 2007b; Novak
et al., 2009)
[22, 31]. Black carbon in soils can be a result of anthropogenic activities like fire pits or natural occurrences like volcanic activity or forest fires (Spokas
et al., 2012)
[41]. Biochar is differentiated from black carbon in that it is created with the intent to be used as a soil ameliorant (Barrow, 2012)
[5]. Specifically, biochar is a stable substrate created from organic material that has been combusted under low or no oxygen conditions through the process of pyrolysis (Atkinson
et al., 2010; Karhu
et al., 2011)
[3, 18]. Biochar may increase soil pH, nutrient retention, cation exchange capacity (CEC), crop biomass, and many other variables important to soil quality and agriculture (Schnell
et al., 2012; Xu
et al., 2012)
[18, 48] in addition to increased soil C sequestration (Lehmann, 2007a)
[22].
