Potassium Nitrate 13.5-0-46
Premium agricultural Potassium Nitrate 13.5-0-46: fully soluble nitrate nitrogen and potassium for high-value crops and professional formulations
Ihumate Potassium Nitrate is a high-specification, fully water-soluble NK fertilizer raw material with KNO3 > 99%, total and nitrate nitrogen > 13.5%, and water-soluble K2O > 46%. The same product category is often marketed as Potassium Nitrate 13-0-46 using rounded whole-number labeling; this page uses the more precise 13.5-0-46 analysis. Its white crystals or crystalline powder intentionally add no chloride, sodium, phosphorus or sulfur, supporting fertigation, hydroponics, sprinklers, foliar programs, and water-soluble or liquid fertilizer production.
1. Two immediately available nutrients: nitrate nitrogen and concentrated soluble potassium support active growth, flowering, fruit set, sizing and quality development.
2. High purity and complete solubility: controlled chloride, moisture and insoluble matter support clear working solutions, lower emitter-blockage risk and reliable use in high-value and soilless crops.
3. Flexible formulation: the phosphorus-free analysis lets agronomists adjust the N:K ratio independently and build high-potassium WSF, liquid and custom NPK formulas.
4. The Ihumate advantage: batch management covers KNO3 assay, nitrate nitrogen, K2O, chloride, moisture, insolubles, pH and appearance, supported by COA, export documents, dependable supply, formulation assistance and OEM/ODM packaging.
Safety and storage: potassium nitrate is an oxidizer. Keep sealed in a cool, dry area away from heat, ignition sources, combustible materials, reducing agents and incompatible chemicals. Transport, labeling and use must follow destination-market rules.

Frequently Asked Questions
1
What is the difference between Potassium Nitrate 13.5-0-46 and 13-0-46?
Both commonly refer to agricultural potassium nitrate. 13-0-46 is a rounded commercial grade, while 13.5-0-46 states a more precise or higher guaranteed nitrate-nitrogen analysis. This product is managed to total and nitrate N > 13.5% and water-soluble K2O > 46%; the contract and batch COA control the final label claim.
2
Which crops and application systems suit Potassium Nitrate?
It suits fertigation, hydroponics, sprinklers, validated foliar feeding and fertilizer production, especially during high-potassium stages in fruits, vegetables, flowers and other high-value crops. Rates must follow crop demand, soil, water and tissue analysis.
3
Is Potassium Nitrate suitable for chloride-sensitive crops?
Potassium nitrate does not use chloride as its nutrient source and this grade controls chloride impurity, making it useful where chloride inputs are restricted. Every fertilizer salt raises solution EC, so concentration and root-zone EC still require management in salt-sensitive crops.
4
Can Potassium Nitrate be mixed with other fertilizers?
It is generally compatible with many fully soluble fertilizers and is commonly used in calcium-containing stock systems. Compatibility still depends on water chemistry and concentration, so run a jar test. Keep it away from combustible materials, strong reducing agents and unverified concentrated pesticide mixtures.
5
Do the specifications printed in the packaging image apply to this product?
No. The image only demonstrates Ihumate bag formats and OEM/ODM design capability. Final guaranteed analysis, hazard marks, net weight and regulatory text follow the contract, batch COA, SDS and destination-market rules.

Application & Dosage: Potassium Nitrate 13.5-0-46
For fertigation, hydroponics, sprinklers, validated foliar feeding and production of high-potassium water-soluble, liquid and custom NPK fertilizers. Potassium nitrate supplies both nitrate N and K, so formulation calculations must include both nutrients and follow crop demand, soil, irrigation-water and tissue analysis.
Agricultural Application
- Fertigation and Hydroponics:Split nitrate N and K applications from late vegetative growth through flowering, fruit set and sizing, correcting concentration from target EC, drainage and tissue analysis.
- Foliar Supplement:Apply an even low-concentration spray in the morning or evening outside high heat and intense light; test sensitive crops, new cultivars and new tank mixes first.
Fertilizer Manufacturing
- Water-Soluble and Liquid Fertilizers:Use as a premium NK source in high-potassium, low-chloride and custom NPK formulas, counting both N and K2O in the calculation.
- Quality and Compatibility Control:Validate solubility, EC, pH and mixture stability at the target water quality and concentration before commercial production.
Application Ratio Scheme
| Crop Name | Growth Stage | Application Ratio |
|---|---|---|
| Fertigation/Sprinklers | Active growth, flowering, fruit set or sizing | 10-25 kg/ha per application; adjust to analysis and local program |
| Hydroponics/Soilless | Nutrient-solution preparation | Calculate from target N, K2O and EC; do not use a fixed field rate |
| Foliar Spray | Young leaves, sensitive crops or first use | 0.5%-1.0%; conduct a crop-safety test first |
| Mature leaves and tolerant crops | 1.0%-2.0%; follow the local label | |
| Fertilizer Production | WSF, liquid and NPK blending | Calculate from target N and K2O analysis |
