Study Development of Available Rare Earth Elements in Soils

Rrae earth elements have been proved to be beneficial to both growth and yield of certain crops.Soil is the major source of rare earth elements for plants.but available rare erath elements (ARE) are only effective.In this paper,the determination,concentration distribution and influencing factors of ARE in soils are reviewed,and some concerned aspects in future study are proposed,which is helpful to agricultural application of ARE.
