Zinc deficiency is easy to miss until yield is already lost. On calcareous sand in Saudi Arabia and the coastal sandy soils of Ilocos and Binh Thuan, pH above 7.5 locks zinc into forms the plant cannot take, and the first visible sign is interveinal chlorosis on the younger leaves, long after the root system has already thinned. This granule puts zinc sulphate into a humate matrix so the zinc is released slowly and stays plant available instead of being fixed by carbonate.
