Zinc Sulfate Fertilizer
Zinc sulfate fertilizer is a vital agricultural input used to provide plants with the essential micronutrient zinc (Zn). This water-soluble fertilizer supports enzyme function, chlorophyll synthesis, and overall plant health, leading to improved growth and higher-quality crops.
Zinc sulfate is particularly effective in correcting zinc deficiencies in soils, which can cause stunted growth and reduced yields in crops like wheat, rice, and maize. Its quick solubility and compatibility with various application methods make it ideal for use in both small-scale farming and large-scale agricultural operations.
Zinc sulfate fertilizer ensures optimal nutrient balance, enhancing root development, flowering, and fruit formation. It is a reliable choice for farmers aiming to increase productivity and crop quality across diverse farming systems.

How to Apply Zinc Sulfate Fertilizer for Optimal Results
Proper application of zinc sulfate fertilizer ensures efficient zinc absorption, healthier crop development, and enhanced productivity. Below is a detailed guide on the best application methods for various agricultural systems:
Drip Irrigation
Zinc sulfate works effectively in drip irrigation systems, ensuring precise nutrient delivery directly to the root zone for optimal uptake.
- Dosage
2–4 kg/ha per application, applied weekly or as needed based on crop requirements. - How to Apply
Dissolve zinc sulfate in water and incorporate it into the drip irrigation system. Ensure uniform distribution and regularly monitor the system for potential clogging due to undissolved particles.
Foliar Application
A highly effective method for addressing acute zinc deficiencies, particularly during critical growth phases such as flowering or fruiting.
- Dosage
2–5 grams per liter of water, applied every 10–14 days. - How to Apply
Mix zinc sulfate with water in a sprayer. Apply evenly to the foliage during cooler times of the day (early morning or late evening) to prevent leaf burn.
Broadcasting
Ideal for larger field applications, ensuring even distribution of zinc across the soil surface.
- Dosage
20–50 kg/ha, depending on the soil's zinc content and crop requirements. - How to Apply
Spread zinc sulfate uniformly over the soil surface and incorporate it lightly into the topsoil to improve availability and reduce leaching.
Hydroponics
Zinc sulfate plays a crucial role in soil-less cultivation systems, ensuring balanced zinc nutrition.
- Dosage
Maintain zinc concentration between 1–2 ppm in the nutrient solution. - How to Apply
Dissolve zinc sulfate in the hydroponic nutrient solution. Regularly monitor pH (5.5–6.5) to maintain optimal nutrient availability.
Important Notes
- Zinc Sulfate can interact with other fertilizers and cause nutrient imbalances.
Mixing zinc sulfate with fertilizers containing phosphates or other metals can form insoluble compounds that hinder nutrient availability. Always check compatibility before mixing. - Overuse of zinc sulfate can lead to toxicity in plants.
Excess zinc can result in plant toxicity, leading to stunted growth or leaf chlorosis. Regularly test soil and plant tissue for zinc levels and adjust dosage accordingly to avoid over-application. - Improper storage of zinc sulfate can reduce its effectiveness.
Zinc sulfate is hygroscopic, meaning it absorbs moisture from the air and can lose its efficacy over time. Store in a cool, dry place to maintain its effectiveness and prevent clumping. - Water quality can impact the effectiveness of zinc sulfate.
Hard or saline water may affect the solubility and uptake of zinc sulfate. Test water quality before application and treat if necessary to ensure maximum nutrient absorption by plants. - Apply zinc sulfate correctly for even distribution.
Uneven application of zinc sulfate can lead to deficiencies or toxicities in some areas. Use calibrated equipment for accurate and uniform distribution across the soil or foliage.

Frequently asked questions
What is Zinc Sulfate fertilizer used for?
Zinc Sulfate fertilizer is primarily used to correct zinc deficiencies in plants, promoting healthier growth and improved crop yields. It enhances enzyme function, improves protein synthesis, and supports chlorophyll production in plants. It is especially beneficial for crops like corn, rice, and wheat that are sensitive to zinc deficiency.
Is Zinc Sulfate organic or synthetic?
Zinc Sulfate is a synthetic fertilizer, produced through chemical processes. It is not classified as organic, but it is widely used in conventional farming to correct zinc deficiencies in soil.
How often should Zinc Sulfate be applied to crops?
Zinc Sulfate should generally be applied once or twice a year, depending on soil conditions and the specific crop requirements. For most crops, it is applied during the planting season or as a foliar spray during growth stages when zinc deficiencies are most likely.
Can Zinc Sulfate be used in hydroponic systems?
Yes, Zinc Sulfate can be used in hydroponic systems to provide zinc to plants. It is typically dissolved in water and added to the nutrient solution. The application rate should be carefully monitored to prevent toxicity in the system.
What is the correct dosage of Zinc Sulfate for foliar application?
