==What Is It?==

==What Is It?==

Biochar is a carbon-rich material produced by pyrolysis of organic feedstocks such as municipal, agricultural, and forestry wastes. It has a high surface area, which enhances soil aggregation, [[water holding capacity]], and [[organic matter| organic carbon content]]. However, biochar properties and effectiveness for pollutant sorption depends on feedstock and pyrolysis conditions. <ref name=Iqbal>Iqbal H, Garcia-Perez M, Flury M.
