Zinc Nacional's Premium OMRI-Listed Zinc Sulfate for Commercial Growers
Maximo 360 is Zinc Nacional's flagship feed and fertilizer grade zinc sulfate monohydrate — a fine, free-flowing powder delivering 35.5% zinc and 17.5% sulfur with 100% water solubility. Trusted by commercial agriculture operations worldwide, Maximo 360 is OMRI listed and certified for use in organic production, making it the preferred zinc source for growers who need a clean, fast-acting micronutrient input across soil, foliar, and hydroponic programs.
Zinc drives growth hormone production, chlorophyll synthesis, carbohydrate metabolism, and cellular respiration. Deficiency shows up fast — stunted growth, interveinal chlorosis, and reduced yields. Maximo 360 corrects it faster.
