[Interaction between rare earths and nitrogen and phosphorus in soil-plant system].

Interaction between rare earths (REs) and nitrogen and phosphorus in soil-plant system is a hot spot in the research field of safety assessment for agricultural utilized rare earths. This interaction directly affects the productivity of arable soil, and is beneficial to assessing the response of rare earths to crop production and the eco-environmental safety. The interaction between rare earths and nitrogen and phosphorus in soil-plant system is briefly summarized, and it's put forward that the interaction between rare earths and nitrogen and phosphorus in the rhizophere of crop, surface layer of arable soil, and plant should be further investigated.
