Crop Nutrition

NOP

purpose

NOP (Potassium Nitrate) is a premium water-soluble fertilizer that supplies both potassium and nitrate nitrogen, free from chloride. Widely used in crop nutrition strategies, NOP is favored for high-value crops and those sensitive to chloride and sodium salts. Its high solubility and rapid absorption make it suitable for fertigation, hydroponics, and foliar sprays, boosting crop quality, resilience, and yield.

  • Provides rapidly available nitrate nitrogen and potassium for fruits, vegetables, flowers, tobacco, potatoes, orchards, and greenhouse crops.​

  • Ideal for crops with high potassium needs during key growth stages (fruit setting, maturation, bulking, flowering).​

  • Used in drip irrigation, hydroponic systems, foliar sprays, base dressing, supplemental feeding, and soilless culture.​

  • Suitable for crops sensitive to chloride or requiring precise nutrient solutions (citrus, strawberries, leafy vegetables, ornamentals).​

  • Enhances fruit quality, color, size, taste, and shelf life; improves stress resistance against drought, heat, and disease.

  • Contains 13–13.7% nitrate nitrogen and 45–46% potassium oxide (K2O), delivering balanced nutrition with an optimal N:K ratio.​

  • Chloride-free—safe for salt-sensitive crops and for mixing in calcium-rich waters without precipitation risks.​

  • Highly soluble, allowing concentrated solutions for efficient fertigation and fast nutrient uptake.​

  • Low salt index, minimizing root and leaf damage compared to other potassium sources.​

  • Boosts plant resilience, root growth, water retention, and disease/pest resistance, leading to improved quality and yields.

Storage:

  • Store in a cool, dry, well-ventilated location, away from sources of heat, moisture, and direct sunlight; NOP is hygroscopic and may clump if exposed to humidity.​

  • Use sealed containers; minimize exposure to air and volatile substances, and avoid proximity to acids or combustible materials.​

  • Recommended storage temperature is below 30°C for stable quality; handle using proper PPE due to dust and oxidizer qualities.​

  • Ensure safe stacking, label packaging, and regular inspection for leaks, damage, or contamination.
