Studies that have reported better crop yields when applying REEs Were located in a different province to the treatment. Increases of 10-24% for vegetable crops, but used control plots that However, there haveĪlso been many studies that may have been compromised by inadequateĭesign or interpretation. (2006) summarised several studies linking theĪpplication of REEs to decreased heavy metal uptake. Plant resilience to cold tolerance or drought (Guo et al. (iii) increasing chlorophyll production (Guo 1993) and (iv) improving Within the plant or in soil microbes (Liu et al. 1997) (ii) stimulating enzymes involved in N processes There have been several mechanisms given as causes suchĪs: (i) increasing nutrient (N, phosphorus and potassium uptake, Researchers have purported to find significant increases in the yield of Thought to be neither essential for life nor toxic. Until recently, little attention had been paid to REEs as they were Hence, commercially available rock phosphates contain REEs (Otero et al.Ģ005), which depending on their composition and use will influence soil

Usually found as flurocarbonates, phosphates, silicates and oxides. Naturally in soil parent materials and total concentrations in soil varyįrom 16 to 219 mg (Hu et al. All the elements (except promethium Pm) exist (lanthanum La) to 71 (lutetium Lu) as well as scandium (Sc, 21) and
