Product Overview
Calcium Nitrate (Ca(NO₃)₂, 15.5% N + 19% Ca) is a fully water-soluble nitrogen-calcium fertilizer that is the backbone of professional fertigation programs worldwide. As the only common fertilizer providing both nitrogen and calcium in water-soluble form, it prevents blossom end rot in tomatoes, bitter pit in apples, and tip burn in lettuce — calcium deficiency disorders that cause significant economic losses. Dongkwang Poland supplies greenhouse-grade and field-grade calcium nitrate to horticultural operations across Europe and beyond.
How Calcium Nitrate Works
Calcium nitrate dissolves completely in water, releasing Ca²⁺ and NO₃⁻ ions. Nitrate-nitrogen is immediately plant-available without soil conversion. Calcium is transported through the transpiration stream to growing tissues — because calcium is phloem-immobile, continuous supply via fertigation is essential for rapidly expanding fruits. The nitrate form also enhances calcium uptake by maintaining charge balance at root surfaces.
Key Benefits
Application Guide
Fertigation: 5-10 kg per 1,000L irrigation water, applied with each irrigation during active growth. For tomatoes: maintain 150-200 ppm Ca in fertigation solution throughout fruiting. For peppers: 120-180 ppm Ca. For lettuce/leafy greens: 100-150 ppm Ca. Foliar: 0.5-1% solution for emergency calcium correction. Do not mix concentrated stock solutions with sulphate or phosphate fertilizers — precipitates will form.
