Zinc is one of the essential micronutrients that acts as a catalyst for activating enzymes required for the synthesis of plant proteins.
Zinc sulphate is used to counter this effect and support root growth. Crops that need to grow on sandy soils or soils with low organic matter (such as carrots, radishes, corn, etc.) often need additional zinc sulphate to ensure the plants can get enough nutrients to develop properly.

Dosage: - Varies as per crops
