Haifa Cal Prime 17-0-0 + 23.5% Ca

Haifa Cal Prime — High-Efficiency Water-Soluble Calcium Nitrate Nitrogen Source

Haifa Cal Prime delivers 17% nitrate nitrogen and 23.5% calcium in the most concentrated, water-soluble calcium nitrate formulation available. With only 0.3% ammonium content, Cal Prime provides a near-pure nitrate nitrogen source that is immediately plant-available, pH-stable, and free of the complications associated with ammonium-based nitrogen in soilless and hydroponic systems.

As a water-soluble nitrogen source, Cal Prime is 17% more concentrated than conventional calcium nitrate — delivering more nitrogen and calcium per kilogram of product, reducing application volumes, and lowering storage and handling requirements.

Nitrate Nitrogen Advantages

• Immediately plant-available — nitrate-N is taken up directly by roots with no soil conversion required
• pH-neutral uptake — nitrate nitrogen does not acidify the root zone the way ammonium does
• Enhances cation uptake — nitrate promotes uptake of calcium, potassium, and magnesium
• No volatility — nitrate does not volatilize; remains available in solution until taken up
• Safe under high light — near-zero ammonium (0.3%) prevents toxic ammonium accumulation under intense irradiation

Why Cal Prime as a Nitrogen Source

• 17% nitrogen — highest nitrogen content of any calcium nitrate formulation
• 23.5% calcium co-delivered — calcium and nitrogen in a single product; no separate calcium source needed
• 17% more concentrated — fewer kilograms needed per tank; reduced freight and storage costs
• Chloride & sodium free — no unwanted ions competing with nitrogen or calcium uptake
• 100% water soluble — dissolves completely; compatible with all fertigation and injection systems

Ideal For

• Hydroponic and soilless nutrient programs requiring a high-efficiency nitrate nitrogen source
• Greenhouse fertigation programs for tomatoes, peppers, cucumbers, and leafy greens
• High-light production environments where ammonium toxicity is a concern
• Operations optimizing nitrogen efficiency and reducing input volume per crop cycle
