The paper reviews chemical properties of vanadium and its distribution in nature, distributional regularities and its chemical combining speciations and biogeochemical significance, and introduced analytical methods of vanadium in soil briefly. Although Vanadium is essential to human, it is toxic to animals and plants if it is received too much. In nature, it mainly lies in the magmatic rocks of basic rocks and ultrabasic rocks and the sedimentary rocks such as mudstones and silicalite and soils. Moreover, its content in soil has close relation with the total content of iron. Its regular analysis is performed by spectrometry method, though it is higher sensitivity to electrochemical method. Although vanadium in soils has several speciations, the soluble and the replaceable statuses are of bio-availability. Furthermore, excess vanadium will cause cancer in several organs or other disease, while inadequate vanadium may lead to other disorders of blood pressure, heart, bone and taste.
