Item description

AgroStar NPK 13:0:45 (Potassium Nitrate) | 100 g

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 100 g 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.

  1. 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.
  2. 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.
  3. 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 100 g 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 100 g 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.
