Humic acid(HA)is a general term for a type of macromolecular organic compounds in humus(HS)that is insoluble in acidic media and widely exists in soil and natural water bodies.This article reviewed the optimization of typical HA extraction methods and the typical research and applications of HA in agriculture,environmental protection,medicine,and other fields.The optimization of extraction methods of HAshould be closely combined with the application scenarios due to the complexity of components.Combined with other materials,HA products obtained via different extraction sources and processes can be applied in an wilder range of fields.
