===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. Effect of biochar on leaching of organic carbon, nitrogen, and phosphorus from compost in bioretention systems.
