Calcium Nitrate is the only 100% water-soluble calcium fertilizer fully compatible with drip fertigation systems. It simultaneously provides 18.8% calcium and 15.5% nitrogen as nitrate in a single application.
Calcium is a structural nutrient critical for cell wall integrity and membrane stability. Since calcium cannot be remobilised within the plant, a continuous supply throughout the growing season is essential for preventing calcium deficiency disorders.
Disorders prevented include: blossom end rot (BER) in tomato, pepper and watermelon; tip burn in lettuce and strawberry; bitter pit in apple; spongy tissue in mango; fruit cracking in pomegranate and lemon. The nitrate form of nitrogen is directly absorbed by roots — no soil conversion needed.
