Introduction of biochar and its impacts on soil: An Overview Author(s):
Ghulam Murtaza and Rose MaryAbstract:
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) 
. Biochar is differentiated from black carbon in that it is created with the intent to be used as a soil ameliorant (Barrow, 2012) 
. 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)
