Agricultural-grade calcium nitrate granules are a highly efficient, water-soluble calcium fertilizer composed of nitrate nitrogen (NO₃⁻) and soluble calcium (Ca²⁺). It is one of the core fertilizers for rapid calcium supplementation, promoting cell division, and enhancing fruit quality.

Hansol Chemical’s calcium nitrate granules feature uniform particle size, rapid dissolution, consistent nutrient content, and high purity—making them a widely used base fertilizer in modern drip irrigation, sprinkler systems, and fertigation programs. They are also commonly adopted by water-soluble fertilizer manufacturers as a premium source of nitrogen (N) and calcium (Ca).

The product is extensively exported to major global agricultural markets including Europe, South America, the Middle East, Southeast Asia, and Africa, and is suitable for diverse crop cultivation scenarios.

Key Product Advantages

1. High Calcium Content for Rapid Supplementation

• Calcium (as CaO) content ≥ 26%

• Available in ionic form for high crop uptake efficiency
  Effectively prevents calcium-deficiency disorders such as fruit cracking, blossom-end rot, hollow fruit, and deformities.

2. Contains Nitrate Nitrogen for Faster Nutrient Uptake

Nitrate nitrogen is the most readily absorbed form of nitrogen by crops, enabling:

• Enhanced root development

• Improved nutrient translocation speed

• Accelerated transport of calcium to leaves and fruits

Synergistic N-Ca interaction maximizes nutrient use efficiency.

3. Fully Water-Soluble Granules Compatible with All Irrigation Systems

Granular calcium nitrate offers:

• No sedimentation or clogging of nozzles

• Rapid, residue-free dissolution

• Compatibility with drip irrigation, sprinklers, and foliar application

Ideal for greenhouse cultivation, protected agriculture, and integrated fertigation systems.

4. Enhances Fruit Quality and Yield

Calcium nitrate delivers outstanding results on fruit and vegetable crops by:

• Increasing fruit firmness and storability

• Boosting sugar content and flavor

• Improving surface gloss and appearance

• Reducing incidence of blemishes and fruit cracking

Widely used on high-value crops such as tomatoes, grapes, strawberries, citrus, and apples.

5. Soil-Safe, Non-Acidifying, and Environmentally Adaptable

As a neutral fertilizer, calcium nitrate does not lower soil pH and is suitable for:

• Acidic soils

• Sandy soils

• Calcium-deficient regions

• High-yield cropping systems
