Fully Water-Soluble Fast-Acting Nitrogen & Calcium Supplement 15.5% Total Nitrogen + 26% CaO White Crystal Fertilizer
calcium ammonium nitrate consists of 1-2mm pure white crystalline granules with a balanced nutrient ratio. it combines dual nitrogen sources (nitrate and ammonium) with high-content soluble calcium. It offers fast absorption, high utilization, and is physiologically neutral, meaning it won’t damage roots or acidify the soil. Suitable for nitrogen and calcium supplementation throughout the crop life cycle, it promotes rapid seedling growth, strengthens shoots, expands fruit, prevents cracking, and improves soil quality for higher yields.
1. Dual Nitrogen Sources - Fast & Long-lasting: Contains 14.4% nitrate nitrogen for immediate absorption and 1.1% ammonium nitrogen for slow release, solving issues like nitrogen deficiency, yellowing, and slow growth.
2. High-Activity Soluble Calcium - Quality & Resistance: With 18.5% soluble calcium and 26% CaO, it quickly replenishes chelated active calcium to prevent physiological diseases like fruit cracking, sunscald, bitter pit, and blossom-end rot. It thickens cell walls and enhances resistance to cold, drought, and lodging.
3. High Purity & Low Impurities - Versatile Application: Water-insoluble matter ≤0.1%. High purity, no residue, and fully soluble. It dissolves quickly into a clear solution, suitable for fertigation, drip irrigation, foliar spray, broadcasting, and basal application without clogging pipes or salt buildup.
4. Soil Regulation & Root Care: A physiologically neutral fertilizer with no strong acid or alkali residues. it alleviates soil acidification and compaction, neutralizes soil acidity, promotes root development, and improves nutrient uptake efficiency in greenhouses, orchards, and open fields.
5. Uniform Granules - Easy Storage & Mixing: 1-2mm regular white crystals with good flowability and resistance to caking. It can be rationally mixed with most secondary/micronutrients and water-soluble fertilizers for synergistic effects.
Expert Advice: Widely used for fruit trees, vegetables, field crops, and flowers. Apply during budding, growth, and fruit expansion stages. Priority should be given to nitrogen and calcium-deficient plots. Continuous use optimizes soil physical and chemical properties.
