AB  - Lanthanum (La) is widely used in various fields. As a consequence, it can accumulate in soil and thus pose a potential hazard to the environment, including a decrease of plant biomass and chlorophyll content. To date, most experimental studies on the biogeochemistry of La have focused on toxic effects resulting from its accumulation in plants growing in La-contaminated areas, while the behavior of La in plants growing in uncontaminated soils has been the subject of much less research. The primary objectives of this work were to investigate the impact of various factors on La uptake by plants growing in uncontaminated soils and to examine the relationships between La and other lanthanides (Ce, Sm, Eu, Tb, Yb, Lu) in the rhizosphere soil and across different plant species. Greenhouse and field experiments were conducted to investigate the patterns of La uptake and its redistribution between different parts of some agricultural plants (wheat and rye) and weeds (couch grass and plantain) growing in clean soils. The correlation between La in the rhizosphere soil, roots, and leaves and between La and other lanthanides in the soil and plants was studied. Although the natural concentration of La in the soils was usually higher than in plants, plant growth in La-uncontaminated soil did not lead to its bioaccumulation. The correlation between La in the rhizosphere soil and roots, as well as between La in roots and leaves, was statistically insignificant. This may be due to a genetically determined need of a particular plant for La. Different plant species growing under the same conditions were capable of accumulating different amounts of La. Despite the assumption that rare earth elements can substitute for Ca, the correlation between La and Ca was often statistically insignificant. On the other hand, in most cases, La had a positive relationship with Ce, Sm, Sc, Fe, and Co.
