Red Star Agricultural Grade Calcium Nitrate Ammonium Salt – Fully Water-Soluble Calcium & Nitrogen Fertilizer for Fruits & Vegetables

Deliver fast, effective calcium and nitrogen nutrition to your crops with Red Star Calcium Nitrate Ammonium Salt. Sourced directly from a specialist fertilizer factory, this agricultural grade calcium nitrate ammonium salt is fully water-soluble, making it ideal for drip irrigation fertigation, foliar spray, and soil application on fruits, vegetables, and field crops. Available in 25kg bags or by the ton for large-scale agricultural operations, it provides the dual nutrition of readily available calcium and fast-acting nitrate nitrogen to promote strong plant growth, prevent calcium deficiency disorders, and maximize crop quality and yield.

Key Benefits

• Fully Water-Soluble Formula – Dissolves completely and rapidly in water without residue, making it perfectly suited for drip irrigation fertigation systems, foliar spray application, and hydroponic nutrient solutions – ensuring efficient nutrient delivery without clogging emitters, nozzles, or irrigation lines.
• Dual Calcium & Nitrogen Nutrition – Provides both readily available calcium and fast-acting nitrate nitrogen in a single product, delivering two essential macronutrients simultaneously to support strong cell wall development, vigorous vegetative growth, and high-quality fruit and vegetable production.
• Prevents Calcium Deficiency Disorders – Regular application prevents common calcium deficiency disorders including blossom end rot in tomatoes and peppers, tip burn in lettuce and cabbage, bitter pit in apples, and cracking in cherries and tomatoes – protecting crop quality and reducing post-harvest losses.
• Fast-Acting Nitrate Nitrogen – Nitrate nitrogen is immediately available for plant uptake without requiring soil conversion, providing rapid green-up and growth response – ideal for correcting nitrogen deficiencies quickly and supporting crops during critical growth stages when fast nutrient availability is essential.
• Suitable for Fruits & Vegetables – Widely used on tomatoes, peppers, cucumbers, strawberries, apples, grapes, citrus, melons, leafy vegetables, and other high-value fruit and vegetable crops that have high calcium demands and benefit from consistent, reliable calcium and nitrogen nutrition throughout the growing season.
• Factory Direct Supply – Bag or Ton – Available in 25kg bags for small to medium operations or by the ton for large-scale agricultural use, sourced directly from the Red Star fertilizer factory to ensure consistent product quality, competitive pricing, and reliable supply for commercial growers.

How to Use

For drip irrigation fertigation: dissolve the required amount in water (typically 1–5 kg per 1000 liters of irrigation water, adjust based on crop nutrient requirements and growth stage) and inject into the drip irrigation system. Ensure the solution is fully dissolved before injection. For foliar spray: dissolve at 0.3–0.5% concentration (3–5g per liter) and apply as a fine mist to both leaf surfaces during cooler parts of the day. Avoid application during flowering. For soil application: dissolve and apply as a soil drench around the root zone or broadcast and water in thoroughly. Apply every 7–14 days during active growth or as required based on crop nutrient monitoring. Do not mix with phosphate or sulfate fertilizers in the same tank. Store in a cool, dry location in sealed bags away from moisture and direct sunlight. Keep out of reach of children and animals.
