Haifa Cal Prime Foliar Calcium Nitrate

Professional foliar calcium nitrate for precise Ca and N delivery

Haifa Cal Prime 17-0-0 + 23.5% Ca is a fully water-soluble calcium nitrate fertilizer for foliar, fertigation, hydroponic, and soilless programs. Its low ammonium content, 0.3% NH₄-N, supplies nitrate nitrogen and soluble calcium for commercial greenhouse and nursery programs where ammonium control matters.

Why use Cal Prime in foliar programs

• 17-0-0 analysis: 16.7% nitrate nitrogen and 0.3% ammonium nitrogen.
• 23.5% calcium: Concentrated soluble calcium for crop nutrition programs.
• Fully water soluble: Prepares a clean nutrient solution when mixed correctly.
• Low ammonium: Helps support tighter control of nutrient-solution chemistry.
• Multi-use format: Suitable for foliar, fertigation, hydroponic, and soilless applications when used according to the crop program and label directions.

Foliar application guidance

The product information lists 2–4 lb. per 100 gallons of water for foliar application. Apply during cooler parts of the day, avoid heat-stressed or wilted plants, and test a small area before broader use. Always follow label directions and current crop requirements.

Compatibility and safety

Do not mix concentrated Cal Prime solutions with phosphate or sulfate sources. Prepare separate stock solutions as needed and verify compatibility with a jar test before tank mixing.

Safety: Calcium nitrate is an oxidizer. Store away from combustible materials, organic matter, and reducing agents. Review the SDS before handling and use appropriate PPE.
