Description
What is Potassium Nitrate Granular?
Potassium Nitrate Granular (KNO₃) is a premium chlorine-free nitrogen-potassium compound fertilizer, engineered for chloride-sensitive crops and precision agriculture. Containing 46.6% potassium oxide (K₂O) and 13.8% nitrate nitrogen (N), its homogeneous 2-4mm granules ensure controlled nutrient release, mechanical spreading compatibility, and zero chloride-induced root burn.
Core Features
1. High Purity & Dual Nutrients
· K₂O 46.6% + N 13.8%：Nitrate nitrogen enables rapid absorption (50% faster than urea), while potassium enhances sugar accumulation and stress resistance.
·Zero Chloride (<1.5%)：Safe for chlorine-sensitive crops (e.g., strawberries, tobacco, citrus), increasing yield by 15-20%
2. Optimized Granular Structure
· Granule Size：2-4mm spherical granules Anti-dust & anti-caking, suitable for mechanical spreaders
· Crush Strength： ≥40N (2× industry standard)Withstands bulk shipping and stacking
· Solubility：100% dissolution in 90s (25°C) No residue in drip irrigation systems
Stability & Functionality
1. Physical Stability for Global Supply
· Moisture Resistance：Hygroscopicity ≤0.3% (vs. industry average 1.5%), ensuring zero caking in humid climates (e.g., Southeast Asia)
· Thermal Stability：Decomposition temperature >334°C, safe for tropical storage.
2. Agronomic Functionality
· Nitrate-Potassium Synergy：Nitrogen promotes leaf growth, while potassium enhances fruit expansion and sugar synthesis (e.g., apple Brix +1-2°).
·Drip Irrigation Optimization：Low salinity (EC<1.5 dS/m) prevents emitter clogging, increasing nutrient use efficiency by 30%

Applications & Solutions
1.Fruit & Vegetables
Enhances Brix level, color, and shelf-life (e.g., grapes, citrus, tomatoes).
2.Tobacco & Cash Crops
Improves leaf thickness, combustibility, and aroma (chloride-free advantage).
3.Hydroponics/Greenhouses
Ideal for precision fertilization due to low salinity index.
Fruit cultivation
Apply 20kg per mu four weeks before harvest to enhance sugar content and color
Tobacco base
The chlorine-free formula enhances blade thickness and flammability
Hydroponic system
The low salt index is suitable for NFT/DFT irrigation

FAQ
Q1: What makes granular superior to powder potassium nitrate?
A: Granules reduce dust loss by 90%, enable uniform field coverage, and cut logistics costs by 7% via bulk shipping compatibility
Q2: Can this product be used in organic farming?
A: Yes, OMRI-listed with heavy metals below EU limits. Complies with USDA/NOP and ECOCERT standards10.
Q3: How to apply granular potassium nitrate in drip irrigation?
A: Pre-dissolve in water at 1:100 ratio, then inject into system. Low salinity (SI=46) prevents clogging – ideal for tomatoes/grape fertigation48.
