Zinc Sulphate

Description

Zinc sulphate (ZnSO₄) is used in the garden as a micronutrient fertiliser when plants lack zinc. It is a strong product, so correct dosing is important.

Zinc is required for:

• leaf and shoot growth
• chlorophyll formation
• crop quality

Signs of zinc deficiency

• pale or yellowish areas between leaf veins
• small leaves and short internodes
• slow growth, often in maize, beans and fruit trees

Use

Foliar spraying, the most effective method

• 0.05-0.1% solution
• 5-10 g of zinc sulphate per 10 L of water
• Spray early in the morning or in the evening
• Apply 1-2 times per season at intervals of 10-14 days

Application to soil

• 1-2 g per 1 m²
• Mix with sand or compost for even distribution
