Zinc Sulphate Monohydrate (ZnSO₄�H₂O) is a highly effective and widely used inorganic micronutrient fertilizer. It provides zinc (Zn) in a readily available sulphate form, essential for correcting zinc deficiency in crops. Zinc is a vital component of numerous enzymes involved in plant growth regulation, protein synthesis, and auxin production. This fertilizer is particularly crucial for cereals like rice and corn, as well as fruit trees, where zinc deficiency can severely limit yields. Its high solubility ensures quick plant uptake through soil application or foliar sprays, making it a cornerstone of modern micronutrient management.
