Calcium Nitrate Tetrahydrate/Calcium Salt

Calcium Nitrate Tetrahydrate Fertilizer (Ca(NO₃)₂·4H₂O) is a highly water-soluble fertilizer supplying readily available calcium and nitrate nitrogen. It is widely used in fertigation, hydroponics, and greenhouse cultivation to prevent calcium deficiency and support healthy crop growth.

This  fertilizer is ideal for:

• Greenhouse and hydroponic crops: tomatoes, cucumbers, peppers, strawberries, lettuce.
• Fruit trees: apples, citrus, grapes, berries.
• Vegetables and leafy greens needing calcium supplementation.

It effectively improves fruit quality, shelf life, and overall crop yield.

• Fertigation / Drip Irrigation: 5–15 kg per 1,000 L water, apply every 7–15 days.
• Foliar Spray: Dilute 2–5 g/L (500–1000×), spray in early morning or evening.
• Hydroponics: Use as a key calcium and nitrogen source in nutrient solutions.

Always adjust dosage based on soil/crop analysis and local agronomic advice.

1. Fast nutrient availability: Both calcium and nitrate nitrogen are immediately absorbable.
2. High solubility: Perfect for modern irrigation systems.
3. Chloride-free and low salt index: Safe for sensitive crops.
4. Dual nutrition: Supplies calcium and nitrogen in one product, improving efficiency.

The main difference lies in their intended applications.

• Agricultural-grade Calcium Nitrate Tetrahydrate is used as a water-soluble fertilizer for vegetables, fruit trees, greenhouse crops, hydroponics, and fertigation systems.
• Industrial-grade Calcium Nitrate Crystal is used in wastewater treatment, rubber manufacturing, concrete admixtures, and other chemical processes, where high purity and controlled impurities are required.
