Zinc (Zn), boron (B), and molybdenum (Mo) are micronutrients, essential to crops, which can be efficiently applied crops via seed coatings. However, fast micronutrient release from soluble coatings brings seedling toxicity risks. Hence, this study developed novel Zn-B-Mo slow-release coating compounds, i.e., nanostructured Zn2Al or Zn3Al-layered double hydroxides (LDHs) loaded with (poly)borate molybdate. Assessment of the properties showed that both LDH compounds gradually dissolved at a pH ∼ 4.5, releasing Zn, B, Mo, while Zn3Al-B-Mo released Mo more slowly than Zn2Al-B-Mo through anion exchange (pH 7). Finally, in establishment trial coated chickpea seeds, elevated doses, prevented adverse effects on emergence yield were observed corresponding due toxicity. Taken together, LDHs prove promising for controlling supply
