Nitrate of Potassium Powder KNO3 Fertilizer

Hydroponics

• KNO₃ is a core component of many hydroponic nutrient formulas, providing both K and NO₃⁻.

• Dosing is calculated based on target ppm of K and N, EC, and the contributions from other salts in the recipe.

• Maintain solution pH and EC within crop‑specific ranges; KNO₃ has a neutral to slightly alkaline effect on solution pH depending on the overall formula.

Foliar application

• Use fully dissolved, filtered solutions at recommended dilution rates to avoid leaf burn.

• Often applied during key growth stages (flowering, fruit set, bulking) to support rapid nutrient uptake through leaves.

• Tank‑mix compatibility should be checked with other foliar products; avoid mixing with incompatible salts or high‑pH materials without testing.

Soil application (drench or banding)

• Can be dissolved and applied as a soil drench around the root zone or used in banding where irrigation is limited.

• Particularly useful for quick correction of K and N deficiencies or as a supplemental feed during critical growth stages.

Always align rates with soil or substrate tests, water analysis, crop nutrient removal, and local extension recommendations to optimize return on investment and avoid over‑fertilization.

Nitrate of Potassium Powder KNO3 Fertilizer in blending and formulation

For fertilizer blenders and formulators, Nitrate of Potassium Powder KNO3 Fertilizer is a key raw material for:

• Water‑soluble NPK blends (e.g., 15‑5‑30, 12‑12‑36, 13‑4‑40) where high K and nitrate‑N are required

• Hydroponic nutrient kits and professional greenhouse mixes

• Specialty foliar products targeting fruit quality, color, and stress tolerance

Because KNO₃ is fully soluble and low in impurities, it integrates cleanly into multi‑component formulations without leaving significant residues or causing compatibility issues when used correctly.

Typical packaging and handling

Common commercial packaging for Nitrate of Potassium Powder KNO3 Fertilizer includes:

• 25 kg multi‑wall paper or PP bags with inner liner for moisture protection

• 50 kg bags for larger agricultural and industrial users

• 1,000 kg jumbo bags (FIBC) for blending plants and bulk buyers

Handling recommendations:

• Store in a cool, dry, well‑ventilated area away from incompatible materials (strong reducers, organic combustibles, acids).

• Keep bags sealed and off the floor on pallets to prevent moisture uptake and caking.

• Use appropriate PPE (gloves, eye protection, dust mask) when handling powder to avoid irritation from dust.

Indicative pricing and market trends

Nitrate of Potassium Powder KNO3 Fertilizer is a higher‑value product compared with bulk MOP or urea, reflecting its purity, solubility, and dual‑nutrient profile. Recent market indications include:

• Bulk agricultural/technical grade KNO₃ in some markets quoted in the range of roughly USD 700–1,200/MT, depending on purity, packaging, and origin.

• China benchmark prices for potassium nitrate reported around USD 712/MT in early September 2026, down month‑on‑month but still above year‑ago levels.

• Retail or small‑pack potassium nitrate (e.g., 25 kg bags, powder form) in some regions priced at approximately USD 1.5–2.0/kg (e.g., INR 130/kg equivalents in certain listings), reflecting packaging, distribution, and smaller volumes.

Actual prices for Nitrate of Potassium Powder KNO3 Fertilizer will vary by:

• Grade (agricultural vs industrial vs laboratory) and purity (≥ 99% KNO₃ vs lower)

• Packaging (25 kg vs 50 kg vs jumbo bags) and order volume

• Origin, freight, and Incoterms (FOB/CIF/CFR)

• Local market dynamics, including demand from greenhouse, hydroponic, and high‑value crop sectors

For accurate budgeting, request formal quotes with full specifications (N, K₂O, Cl, moisture, insolubles), packaging options, and validity from several KNO₃ suppliers or manufacturers.

Sourcing Nitrate of Potassium Powder KNO3 Fertilizer

For distributors and large buyers, Nitrate of Potassium Powder KNO3 Fertilizer is available from:

• Specialized potassium nitrate manufacturers serving agriculture, greenhouse, and industrial markets

• Fertilizer trading companies importing KNO₃ from major producing regions (including China and other industrial hubs)

• Regional blenders formulating water‑soluble NPK and hydroponic nutrients using imported KNO₃ powder

When evaluating suppliers, focus on:

• Verified nutrient analysis (N, K₂O, nitrate‑N) and impurity limits (Cl, insolubles, moisture) on the CoA

• Physical quality: free‑flowing powder, low dust, consistent particle size for easy dissolution and handling

• Packaging integrity and moisture protection to ensure product stability during storage and transport

• Technical support for fertigation, hydroponic recipes, and crop‑specific programs

Positioning in commercial catalogs

For SEO and commercial catalogs, Nitrate of Potassium Powder KNO3 Fertilizer is typically positioned with phrases such as:

• “Fully water‑soluble potassium nitrate 13‑0‑46 for fertigation and hydroponics”

• “Chloride‑free KNO₃ powder fertilizer for high‑value crops and foliar feeding”

• “Premium nitrate of potassium powder for greenhouse, hydroponic, and precision agriculture”

These descriptors align with buyer searches for potassium nitrate fertilizer, KNO₃ powder, 13‑0‑46 fertilizer, and soluble K+N sources, supporting both distributor listings and grower‑facing product pages.

Key takeaways for buyers and formulators

For buyers specifying Nitrate of Potassium Powder KNO3 Fertilizer, the most important parameters are:

• Clear N and K₂O content (e.g., 13.5% N, 46% K₂O) and confirmation that N is primarily nitrate

• Low chloride, low insolubles, and low moisture for clean, clog‑free irrigation and hydroponic systems

• Proven solubility and physical quality (free‑flowing powder, minimal dust) for easy handling and dosing

• Competitive pricing with transparent specs, packaging, and Incoterms

For formulators, KNO₃ is a cornerstone ingredient for high‑performance water‑soluble fertilizers and hydroponic nutrients, enabling precise control of nitrate‑N and potassium while maintaining solution clarity and system reliability.

Used correctly in fertigation, hydroponics, foliar, and soil programs, Nitrate of Potassium Powder KNO3 Fertilizer can be a high‑ROI input for growers focused on yield, quality, and efficient nutrient use in high‑value crop production. Contact
