Introduction to Calcium Nitrate Granules for Gardening

Calcium nitrate granules are an essential fertilizer for every gardener aiming to grow healthy, high-yielding plants. A water-soluble, fast-acting nutrient source, calcium nitrate delivers calcium and nitrogen – two vital elements that significantly boost plant health, improve flowering, and prevent common nutrient deficiencies. Whether you're growing vegetables, fruits, or ornamental plants, using calcium nitrate ensures a stronger root system, better nutrient absorption, and vibrant growth.

What is Calcium Nitrate?

Calcium nitrate is an inorganic compound with the chemical formula Ca(NO₃)₂. It is a white crystalline granule that dissolves easily in water, making it a popular choice for fertigation and foliar spray. It contains two primary nutrients:

• Calcium (Ca) – 18-19%
• Nitrate Nitrogen (NO₃-N) – 15-16%

These nutrients work together to improve the overall health and productivity of plants. Unlike other nitrogen sources, nitrate nitrogen is immediately available to plants, promoting quick green-up and vigorous growth.

Benefits of Using Calcium Nitrate Granules in Gardening

1. Improves Root Development
   Calcium strengthens cell walls and supports healthy root systems. This ensures plants can uptake nutrients more efficiently, leading to healthier growth.
2. Prevents Calcium Deficiency
   Common symptoms like blossom-end rot in tomatoes or tip burn in leafy vegetables are caused by calcium deficiency. Calcium nitrate eliminates this issue effectively.
3. Boosts Yield & Quality
   Regular application improves the quality and shelf life of fruits and vegetables, leading to higher market value and reduced post-harvest losses.
4. Enhances Photosynthesis
   Nitrogen in nitrate form aids in chlorophyll production, improving photosynthesis and plant vigor.
5. pH Neutral & Non-Acidifying
   Unlike ammonium-based fertilizers, calcium nitrate doesn't acidify soil, keeping pH levels stable and healthy for soil microbes.
6. Ideal for Hydroponics & Soil Gardening
   100% water-soluble and free-flowing, perfect for hydroponic systems, drip irrigation, and foliar sprays.
7. Reduces Soil Toxicity
   Helps displace harmful sodium ions in soil, thus reclaiming saline or sodic soils effectively.
8. Supports Early Growth and Flowering
   Encourages rapid growth during the early vegetative stage and supports flowering with improved nutrient supply.

How to Use Calcium Nitrate Granules in Your Garden

1. Soil Application:

• Dosage: Mix 1-2 teaspoons per plant or 25-50g per square meter of soil.
• Frequency: Once every 15–20 days during active growth stages.
• Application: Broadcast around the base of the plant and water thoroughly.

2. Foliar Spray:

• Dosage: Dissolve 5-10g (1-2 teaspoons) in 1 liter of water.
• Application: Spray on leaves in the early morning or late evening.
• Frequency: Every 10-15 days or as required.

3. Drip Irrigation / Hydroponics:

• Dosage: Use 1-1.5g per liter of water in the nutrient solution tank.
• Application: As part of the regular fertigation schedule.

Best Time to Apply Calcium Nitrate

• At the vegetative stage to boost root and shoot growth.
• During flowering to enhance fruit/flower set.
• After fruit formation to prevent disorders like blossom-end rot and tip burn.

Suitable Plants for Calcium Nitrate Application

• Vegetables: Tomatoes, peppers, brinjal, cabbage, cauliflower, spinach, lettuce.
• Fruits: Citrus, grapes, bananas, strawberries, apples.
• Flowers: Roses, hibiscus, marigold, chrysanthemum.
• Leafy Greens: Palak, amaranthus, coriander.

Storage Instructions

• Store in a cool, dry place away from direct sunlight.
• Reseal the pack tightly after each use.
• Keep out of reach of children and pets.

Safety Tips

• Wear gloves while handling.
• Avoid contact with eyes and skin.
• Do not ingest. For external gardening use only.
