The extent, rates, and implications of these interactions, however, are far from understood. This review describes the properties of biochars and suggests possible reactions that may occur after the addition of biochars to soil. These include dissolution–precipitation, adsorption–desorption, acid–base, and redox reactions. Attention is given to reactions occurring within pores, and to interactions with roots, microorganisms, and soil fauna. Examination of biochars (from chicken litter, greenwaste, and paper mill sludges) weathered for 1 and 2 years in an Australian Ferrosol provides evidence for some of the mechanisms described in this review and offers an insight to reactions at a molecular scale. These interactions are biochar- and site-specific. Therefore, suitable experimental trials - combining biochar types and different pedoclimatic conditions - are needed to determine the extent to which these reactions influence the potential of biochar as a soil amendment and tool for carbon sequestration.||Publication Type:||Journal Article||Source of Publication:||Australian Journal of Soil Research, 48(7), p. 501-515||Publisher:||CSIRO Publishing||Place of Publication:||Australia||ISSN:||0004-9573
