Fully Water-Soluble Potassium Nitrate 13-0-46 is a high-purity fertilizer supply combining nitrate nitrogen and potassium in a single, readily available material. With an N-P2O5-K2O ratio of 13-0-46, it serves as a primary source of concentrated potassium and fast-acting nitrate nitrogen without adding phosphate.

Key Technical Advantages
Targeted Nutrient Delivery
The 13-0-46 analysis provides concentrated potassium alongside nitrate nitrogen, the preferred nitrogen source for direct plant uptake. Because it contains 0% P2O5, it allows formulators and growers to adjust potassium levels independently without altering phosphate balances in the overall nutrient program.
Rapid Solubility for Technical Application
Engineered specifically for fluid applications, this grade dissolves rapidly without leaving residues that could clog drip emitters, spray nozzles, or proportioning pumps in greenhouse and fertigation equipment.
Low-Chloride Profile
Ideal for chloride-sensitive crops (such as tobacco, fruits, and high-value vegetables) and saline soils. Buyers can request exact chloride testing thresholds on the COA to meet strict formulations.
Applications
Fertigation Systems: Suitable for drip, sprinkler, and pivot irrigation in field crops and commercial horticulture.
Hydroponics and Soilless Cultivation: Provides essential K and NO3-N in closed-loop and run-to-waste nutrient solution recipes.
Greenhouse Crop Production: Meets the precise daily nutrient requirements of vegetables, cut flowers, and nursery stock.
Fertilizer Manufacturing: Serves as a soluble raw material for producing dry water-soluble or liquid NK and NPK blends.
Quality Control and Procurement Standards
Crystallization and Moisture Control: Controlled drying prevents caking and maintains free-flowing physical handling properties during storage and blending.
Particle Size Management: Systematic screening minimizes fine dust and ensures uniform particle distribution.
Batch Qualification: Every production lot undergoes lab testing for nutrient content, insoluble matter, moisture, chloride levels, and purity prior to release.
Packaging and Logistics
Packaging Options: 25 kg woven PP/PE bags, 500 kg, 1000 kg, or 1200 kg jumbo bulk bags with discharge spouts.
Loading Capacity: Typically 25 to 27 Metric Tons per 20ft container (unpalletized) or 20 to 24 Metric Tons (palletized with stretch wrap)
Storage: Store in a cool, dry, well-ventilated warehouse away from combustible materials and direct heat sources.
Commercial Qualification Checklist
Before issuing a purchase order for bulk potassium nitrate, professional buyers should confirm:
- Guaranteed N and K2O analysis matching formulation calculations.
- Verified limits for chloride and water-insoluble matter on the technical specification sheet.
- Availability of batch-specific Certificate of Analysis (COA), Technical Data Sheet (TDS), and Safety Data Sheet (SDS).
- Compliance with destination country fertilizer regulations (e.g., EU REACH compliance for European markets).
FAQ
Q: What does the 13-0-46 rating represent?
A: 13-0-46 indicates that the product contains 13% Total Nitrogen (strictly in nitrate form), 0% Phosphate (P2O5), and 46% Soluble Potash (K2O) equivalent by weight.
Q: Is this product suitable for hydroponic nutrient solutions?
A: Yes, this fully water-soluble grade is designed for hydroponic systems and fertigation, providing readily available nitrate nitrogen and potassium without leaving clogging residues.
Q: How does Potassium Nitrate 13-0-46 differ from Potassium Chloride (MOP) or Potassium Sulfate (SOP)?
A: Potassium Nitrate supplies both nitrogen and potassium without chlorine or sulfur. Unlike Potassium Chloride, it avoids chloride toxicity in sensitive crops, and unlike Potassium Sulfate, it provides fast-acting nitrate nitrogen instead of sulfur.
Q: What documents are provided for quality assurance before placing a bulk order?
A: Standard technical support documentation includes the Product Specification Sheet, Technical Data Sheet (TDS), Safety Data Sheet (SDS), and a batch-specific Certificate of Analysis (COA).
Q: What packaging formats and container loading capacities are available?
A: Common packaging formats include 25 kg bags and 1000 kg bulk bags. A standard 20ft container typically accommodates 25 to 27 Metric Tons depending on palletization requirements and destination transport limits.
