Standard chemical composition and nutrient synergy
Calcium Nitrate provides two essential plant nutrients in an immediately bioavailable ionic form.
- Nitrate Nitrogen (NO3-N): Approximately 14.4 to 15.5 percent, readily absorbed by plant roots without requiring soil transformation.
- Water-Soluble Calcium (Ca): Approximately 18.8 to 19 percent, essential for cell wall pectin synthesis and membrane stability.
- Complete water solubility: Dissolves rapidly without insoluble residue, making it ideal for micro-irrigation systems.
- Synergistic uptake: Nitrate anions stimulate simultaneous root uptake of positively charged calcium and potassium cations.
Physiological benefits and prevention of crop disorders
Adequate calcium nutrition is vital for fruit quality, firm texture, and resistance to environmental stress.
- Blossom end rot prevention: Eliminates black necrotic scarring at the bottom of developing tomatoes, peppers, and watermelons.
- Tip burn mitigation: Prevents edge margin necrosis in cabbage, cauliflower, and leafy greenhouse crops.
- Fruit firmness and shelf life: Strengthens cell walls, reducing post-harvest fruit cracking, bruising, and storage rot.
- Root apical growth: Stimulates active root elongation and secondary root proliferation in acidic or sodic soils.
Fertigation protocols, mixing compatibility, and FCO norms
Apply Calcium Nitrate through drip fertigation tanks or as a foliar spray during active vegetative growth and early fruit development. Never mix Calcium Nitrate in the same concentrated stock solution tank with soluble phosphate or sulphate fertilisers (such as 0-52-34 or SOP), as insoluble calcium phosphate or gypsum precipitates will clog drip emitters. Ensure packaging bears the mandatory FCO specification seal.

Common questions
What is the nutrient grade of Calcium Nitrate fertiliser?
Calcium Nitrate contains approximately 15.5 percent nitrate nitrogen and 18.8 percent water-soluble calcium.
Why should Calcium Nitrate not be mixed with sulphate or phosphate fertilisers?
Mixing with sulphates or phosphates causes calcium to precipitate into insoluble gypsum or calcium phosphate, clogging drip emitters.
What physiological disorder does Calcium Nitrate cure in tomatoes?
It cures blossom end rot, a localized calcium deficiency that causes dark sunken lesions at the base of developing tomato fruits.
