Zinc Fertilizers

Zinc fertilizers are applied to soil mainly with NPK fertilizers, either by incorporating at the factory or bulk blending in granular form with other granular fertilizers. Soluble Zn fertilizers also are applied as foliar sprays to fruit and vegetable crops.

Sprinkling zinc fertilizer granules directly onto the soil surface is a common practice in agricultural production. Zinc is one of the essential microelements for plant growth, playing a critical role in physiological development, photosynthesis, and disease resistance. Below is a detailed guide on how to apply zinc fertilizer granules via surface sprinkling, along with key usage precautions.

1. Preparation Phase

• Selecting Zinc Fertilizer Granules: Various types of zinc granules are available, such as zinc sulfate (ZnSO₄) and zinc oxide (ZnO). Choose based on crop requirements. Zinc sulfate is suitable for most crops, while zinc oxide is preferable for acidic soils.

• Soil Testing: Conduct a soil analysis before application to determine zinc content and pH levels. This helps determine the appropriate type and dosage of zinc fertilizer.

2. Application Method

• Uniform Sprinkling: Distribute granules evenly across the soil surface to avoid over-concentration or excessive dispersion, ensuring balanced nutrient absorption by plants.

• Soil Incorporation: After sprinkling, deeply till the soil to mix granules thoroughly with the soil. This enhances nutrient absorption and promotes root growth.

3. Timing of Application

• Optimal Seasons: Spring and autumn are ideal for zinc fertilization due to moderate temperatures, which favor crop growth and fertilizer decomposition.

• Avoid Heat Stress: Refrain from applying during high-temperature periods (e.g., midday) to prevent nutrient loss. Instead, apply in the morning or evening.

4. Dosage Guidelines

• Crop-Specific Adjustments: Dosage depends on crop type, growth stage, and soil conditions. A general recommendation is 5–10 kg per mu (approx. 0.05–0.1 kg/m²).

• Soil-Based Calibration: Adjust according to soil zinc levels and pH. For zinc-deficient soils, increase dosage slightly; for acidic soils, opt for alkaline zinc formulations.

5. Key Precautions

• Prevent Overapplication: Excessive zinc can cause root burn and inhibit growth. Adhere to recommended dosages.

• Combine with Other Fertilizers: Zinc can be applied alongside nitrogen, phosphorus, or potassium fertilizers to improve efficiency. Avoid overloading to prevent waste.

• Environmental Protection: Zinc decomposition may release harmful substances. Ensure proper application to avoid soil or water contamination.

Surface sprinkling of zinc fertilizer granules is a straightforward method, but success requires careful selection of products, soil testing, precise dosing, timing, and environmental awareness. When implemented scientifically, this approach effectively enhances crop quality and yield.
