Biochar use as soil amendment can influence both physical and chemical properties of soil. The effects of biochar depend on the raw material from which biochar is derived as well as on the used processing technology and process conditions. One commonly highlighted benefit of biochar application is improved water retention properties of soil. Biochar may affect water retention in direct or direct way. In direct mechanism water is stored and held in the biochar pores while in indirect mechanisms biochar contributes to the soil structural development (aggregation).
