Green OK Calcium Nitrate Granula Soluble Fertilizer | 25kg

Green OK Calcium Nitrate Granula Soluble Fertilizer | 25kg is a fully water-soluble, granular fertilizer that provides two essential nutrients in a readily available form: Nitrogen (N) and Calcium (Ca).

1. Brand: Green OK (A common brand in agricultural supplies, known for quality fertilizers).
2. Form: Granula (Granular) – These are small, hard pellets that are easy to handle and dissolve completely in water.
3. Solubility: Fully Soluble – Designed to be dissolved in water and applied through irrigation systems like drip (fertigation), sprinklers, or as a foliar spray.
4. Pack Size: 25 kg Bag – A standard, commercial-sized bag.

Specifications of Green OK Calcium Nitrate Granula Soluble Fertilizer | 25kg:

The exact NPK ratio might vary slightly by manufacturer, but for Calcium Nitrate, it is generally very consistent.

• Total Nitrogen (N): 15.5%

  • Nitrate Nitrogen (NO₃-N): 14.5%

  • Ammonium Nitrogen (NH₄-N): 1.1%

• Water-Soluble Calcium (CaO): 26.5% (which is approximately 19% elemental Calcium)

This means a 25kg bag contains roughly:

• 3.87 kg of Total Nitrogen

• 4.75 kg of elemental Calcium

Why is This Fertilizer So Important? Key Benefits:

1. Rapid Correction of Calcium Deficiencies: Calcium is crucial for cell wall development. A lack of it leads to common disorders like:

   • Blossom End Rot in tomatoes, peppers, and watermelons.

   • Tip Burn in lettuce and cabbage.

   • Bitter Pit in apples.

2. Fast-Acting Nitrate Nitrogen: The nitrogen is primarily in the nitrate (NO₃) form. This is immediately available for plant uptake, unlike other forms that need to be converted by soil microbes first. This provides a quick “greening” and growth boost.

3. Prevents Calcium Lockout: Unlike many other fertilizers, calcium nitrate is unique because it provides calcium in a form that doesn’t tie up with other elements in the soil or water. It is the only effective way to deliver calcium through an irrigation system without causing clogging or precipitation.

4. Improves Fruit Quality and Shelf Life: Adequate calcium leads to firmer, better-quality fruits and vegetables that are less prone to bruising and have a longer post-harvest life.

5. Suitable for All Irrigation Systems: Its high solubility makes it ideal for modern precision farming techniques like drip fertigation, hydroponics, and foliar feeding.

How and When to Use It:

Application Methods:

1. Fertigation (Drip/Irrigation): The most common method. Dissolve the required amount in water and inject it into your irrigation system.
2. Foliar Spray: Dissolved in water and sprayed directly onto plant leaves for a quick corrective measure.
3. Side-Dressing: Granules can be applied directly to the soil near the plant roots and watered in.

Ideal for These Crops:

1. Fruits: Tomatoes, Peppers, Cucumbers, Melons, Watermelons, Strawberries, Apples, Grapes.
2. Vegetables: Lettuce, Cabbage, Broccoli, Celery, Potatoes, Carrots.
3. Ornamentals & Flowers: To strengthen cell walls and improve overall plant vigor.
4. Field Crops: Such as cotton and tobacco.

Important Warnings & Precautions:

1. DO NOT Mix with Phosphates or Sulfates: Calcium nitrate will react with fertilizers containing phosphate (e.g., MAP, MKP) or sulfate (e.g., Potassium Sulfate, Magnesium Sulfate) to form insoluble precipitates that will clog your irrigation system and become unavailable to plants.
2. Store in a Cool, Dry Place: The granules are hygroscopic (they absorb moisture from the air) and can become lumpy or hard to handle if stored improperly. Keep the bag sealed.
3. Follow Recommended Rates: Over-application can lead to salt build-up in the soil. Always follow soil test recommendations or standard dosage guidelines for your specific crop.
