Item description

AgroStar NPK 13:0:45 (Potassium Nitrate) | 25 kg

AgroStar NPK 13:0:45 (Potassium Nitrate) supplies nitrate nitrogen and water-soluble potash for crop nutrition, including post-bloom and physiological-maturity programmes. It is a nitrogen-and-potassium grade, not a balanced supply of all three NPK nutrients. This listing is the 25 kg pack.

Nutrient focus: Supplies nitrogen in nitrate form and potash expressed as K₂O; the 45 is not elemental potassium.

Stage-related purpose: AgroStar positions the grade for post-bloom and physiological-maturity nutrition. Match that purpose to the crop’s actual nutrient need.

Important handling warning: The safety data sheet identifies an oxidizer that may intensify fire. Keep away from heat, combustible materials and incompatible substances.

Why Choose This Product? Key Benefits

🌿 Nitrate nitrogen: Declares total nitrogen, all in nitrate form, at a minimum of 13.0%.
🍊 Potassium-focused nutrition: Declares water-soluble potash as K₂O at a minimum of 45.0% for an appropriate crop-nutrition programme.
🌼 Post-bloom purpose: AgroStar describes use in flowering, fruiting and maturity-related nutrition without guaranteeing flower or fruit size.
💧 Water-soluble product: Listed for spray, fertigation and drenching; each route requires its own complete product, water and treatment basis.

How It Works: Plant Nutrition

The grade describes nutrient supply, not a pesticide mode of action or a guaranteed crop response. The nitrate and potash contributions must fit the crop’s overall nutrient balance.

Understand nitrate nitrogen: The 13.0% declaration is nitrogen in nitrate form, not 13% nitrate-ion mass. Count it alongside nitrogen from the rest of the fertilizer programme.
Read potash as K₂O: The 45.0% minimum is the potash expression K₂O, not elemental potassium. Do not substitute a different potassium grade or assume every potassium source has identical directions.
Match purpose and stage: AgroStar positions this grade for post-bloom and physiological-maturity nutrition, including flower and fruit development. That purpose does not establish a universal application date, rate or guaranteed stress resistance.

Crop Suitability & Nutrition Purpose

AgroStar describes broad crop use. Choose the programme from the crop’s nutrient requirement, stage, soil and irrigation-water conditions; “all crops” is not a universal recipe.

Crop / Use	Nutrition Purpose & Conditions
General crop nutrition	Use where the crop programme calls for nitrate nitrogen and potassium. Identify the actual nutrient requirement before treatment rather than treating every crop symptom as a deficiency.
Post-bloom and maturity	AgroStar describes use after bloom and at physiological maturity. Match the stage to the crop and nutrition plan. No fixed days-after-sowing or automatic repeat schedule is implied.
Flower and fruit development	Intended to support flower, fruit and shoot nutrition where the declared nutrients are required. Improved size, quality, yield or tolerance to abiotic stress is not guaranteed.
Soil and water conditions	For saline soils or calcium-enriched irrigation water, obtain soil- and water-specific crop advice before use. This is not a salinity-remediation treatment, and a water-suitability statement does not permit calcium-containing tank mixes.

Dosage & Application Guide

Before preparing a solution, confirm the complete current directions for the crop, stage and route. Keep the product quantity, final water volume and treated-area or root-zone basis together.

Application Requirements

Foliar spray: Confirm the crop stage, product quantity, matching total spray-water volume and intended coverage. Do not derive a per-litre or tank recipe from an acre quantity or pack size.

Fertigation or drenching: Confirm the water volume, placement, treated area or root-zone basis and timing. Do not treat a concentration and a kilogram-per-area statement as interchangeable directions.

Timing and further applications: Post-bloom and physiological maturity are nutrition purposes to match to the crop. Further applications depend on crop growth, crop life and advice; they are not a fixed interval or an automatic calendar.

Pack quantity: The 25 kg pack is the sale quantity. Measure only the amount required by the confirmed crop programme; a whole pack does not automatically belong in one sprayer or irrigation tank.

How to Apply: Best Practices

Confirm crop and nutrient need: Review soil and water conditions, crop stage and other fertilizer inputs with a qualified adviser. Do not use this grade as a pesticide or as a substitute for salinity management.
Choose the correct route: Use separate complete spray, fertigation or drench directions. Do not transfer an unpaired root-zone concentration to a foliar spray.
Prepare solutions separately: AgroStar advises against direct chemical mixing. Prepare separate water solutions and combine only when the exact mixture and both products’ directions permit it.
Respect compatibility exclusions: Do not mix with sulphur-, calcium- or lead-containing compounds. Calcium-enriched irrigation water is not the same as permission to add a calcium fertilizer or other calcium-containing partner.
Handle as an oxidizer: Keep away from heat, flammable or combustible materials, reducing agents, powdered metals, strong acids and organic materials. Do not smoke; prevent contamination with incompatible substances.
Control dust and protect water: Use ventilation and required PPE. Keep product, spills, surplus solution and washings out of drains and water sources.
Record and reassess: Record the crop stage, route and amount used. Reassess nutrient need before further applications instead of repeating automatically.

Frequently Asked Questions

1. Does 13:0:45 mean 45% elemental potassium?
No. The water-soluble potash is expressed as K₂O at 45.0% minimum. Total nitrogen is 13.0% minimum, all in nitrate form. The grade is not a balanced three-nutrient feed.

2. When does this grade fit a crop programme?
AgroStar positions it for post-bloom and physiological-maturity nutrition, including flower and fruit development. Match the actual crop stage, soil and water conditions and nutrient requirement; a stage-related purpose is not a complete dose schedule.

3. Does the 25 kg pack define a tank or acre dose?
No. Confirm product quantity, final water, crop stage, route and treatment basis before measuring. Pack weight alone does not establish an application rate.

4. Can I mix it with calcium because the page mentions calcium-enriched water?
No blanket mixing permission follows from that statement. AgroStar excludes calcium-, sulphur- and lead-containing mixing partners. Check irrigation-water quality and the exact proposed mixture separately with qualified advice.

5. Is potassium nitrate harmless because it is a fertilizer?
No. The product SDS identifies an oxidizer that can intensify fire. Keep it away from combustible and incompatible materials, follow dust/eye/skin protection and store it securely.
