Organic fertilizers of La, Nd, and Pr with tartaric acid ligands have been successfully synthesized. The efficiency of the complexing reaction was over 80%. The molecular formula of the complex was Ln2(C4H4O6)3.nH2O (Ln: La, Nd, Pr). The synthesized complexes were tested for the ability to stimulate growth and improve productivity for Thai cucumber. The study results showed that the complexes reduced the growth time of the plants and increased the yield by 20%. Yields of cucumbers sprayed with rare earth tartrate complexes reached ~62 tons/ha and increased by 20% compared with control samples.
