AB - Bioavailable ligands that bind metals mediate their uptake in plants, leading to the study of artificial ligands as potential fertilizers. Proline-2′-deoxymugineic acid (PDMA) has shown a high affinity for FeIII, enhancing iron uptake in rice and suggesting that it could be used for improving zinc uptake. This work studied chemical solution parameters, i.e., redox potential, ion strength, pH, and ligand/metal concentrations controlling ZnII–PDMA complex formation in rice-producing soils using geochemical speciation modeling. We show that PDMA is generally selective for ZnII in reducing, saline, and alkaline soil solutions. Comparison with a recent micronutrient uptake study in rice suggests that free PDMA should be added in reducing conditions to avoid competition with CuII and FeIII or as the ZnII–PDMA complex at pH below 9. The Zn/M ratios (M = CuII, FeIII) needed to form stable ZnII–PDMA complexes were also identified. This study shows the promise of PDMA as a fertilizer to overcome zinc deficiencies in alkaline and flooded soils.
