Product Details
Calcium Nitrate is a highly efficient water-soluble fertilizer that provides immediately available nitrate nitrogen and calcium for rapid plant uptake. It is widely used in fertigation, drip irrigation, foliar feeding, and greenhouse production to improve crop yield, fruit quality, and nutrient efficiency.
The combination of fast-acting nitrogen and highly available calcium helps promote vigorous growth, stronger root systems, improved fruit firmness, and reduced physiological disorders caused by calcium deficiency.
Key Functional Advantages:
- Provides fast-available nitrate nitrogen for immediate crop response
- Supplies highly soluble calcium to support cell wall development
- Improves fruit quality, firmness, and shelf life
- Enhances nutrient uptake and fertilizer efficiency
- Fully water-soluble with no residue
- Ideal for fertigation, drip irrigation, and foliar application
Its excellent solubility and nutrient availability make it one of the most widely used calcium fertilizers in modern agriculture.

Frequently Asked Questions
Calcium Nitrate Fertilizer is a highly soluble source of nitrogen and calcium. It is widely used to promote vigorous plant growth, improve fruit quality, strengthen cell walls, and increase crop yield. It is suitable for vegetables, fruits, greenhouse crops, potatoes, berries, and field crops.
Calcium Nitrate provides fast-available nitrate nitrogen and readily absorbable calcium. It helps improve nutrient uptake, supports root development, enhances fruit firmness, extends shelf life, and reduces calcium-related disorders in crops.
Yes. Calcium Nitrate is commonly used to help prevent blossom end rot in tomatoes, peppers, cucumbers, and other fruiting crops by supplying readily available calcium during critical growth stages. Consistent irrigation and proper nutrient management are also important for effective prevention.
Calcium Nitrate can be applied through drip irrigation, fertigation systems, foliar feeding, or direct soil application. Because it is fully water-soluble, it dissolves quickly and delivers nutrients efficiently to plant roots and developing tissues.
Calcium Nitrate is compatible with many fertilizers, but it should not be mixed directly with concentrated phosphate or sulfate fertilizers, as precipitation may occur. For fertigation systems, separate stock solutions are recommended to maintain nutrient availability.
