Calcium Nitrate UAE – Complete Guide for Hydroponic & UAE Farmers

Calcium Nitrate (CaNO3) is one of the most important fertilizers for UAE hydroponic growers and soil farmers. It provides two critical plant nutrients — calcium (Ca) and nitrogen (N) — in a 100% water-soluble form that plants can absorb immediately. This guide covers everything UAE buyers need to know.

Why Calcium Nitrate is Essential for UAE Growing

UAE’s growing conditions create specific challenges that calcium nitrate directly addresses:

• UAE tap water is low in calcium — desalinated water lacks adequate calcium, making supplementation essential
• RO water has zero calcium — if you use reverse osmosis water (common for UAE hydroponics), you must add calcium nitrate
• Prevents blossom end rot — critical for UAE-grown tomatoes, peppers, and cucumbers
• Strengthens cell walls — plants grown in UAE’s hot climate need strong cells to resist heat stress
• Provides fast-release nitrogen — 15.5% nitrate-nitrogen for immediate plant uptake

Calcium Nitrate Specification – UAE Hydroponics Grade

Our Calcium Nitrate CaNO3 contains: 15.5% Nitrogen (all in nitrate-N form), 18.5% Calcium (water-soluble), 100% water solubility, suitable for hydroponic, drip, and fertigation systems.

How to Use Calcium Nitrate in UAE Hydroponics

Important: Never mix concentrated calcium nitrate solution with concentrated sulfate solutions (Epsom salt, potassium sulfate) — they will react and form insoluble calcium sulfate. Always dilute in your reservoir water separately first.

Hydroponic dosage: 700–900 ppm calcium nitrate as part of your complete nutrient solution. For RO water, start with 500mg/L and adjust based on plant response and EC readings.

Soil/fertigation dosage: 2–3g per liter applied weekly during vegetative and early fruiting stages.

Calcium Nitrate vs Calcium Chloride in UAE

Always choose calcium nitrate over calcium chloride for growing applications. Calcium chloride provides chloride (Cl) which can accumulate in soil and hydroponics to toxic levels. Calcium nitrate provides beneficial nitrate nitrogen instead.
