Abstrakt:	The article presents a study that examines the contribution of common soil organic and inorganic components to butachlor sorption. It states that butachlor has been widely used in Asia and South America for the control of annual grasses, and it also applied in China as herbicides, however, its widespread use has led to a high content in soils and water, causing serious environmental problem. The study observes six kinds of pure minerals such as montmorillonite, kaolinite, and amorphous hydrated iron oxides to evaluate their contributions to butachlor sorption. The study finds out the potential association of clay minerals, and soil organic and inorganic components to butacholor sorption.
