Item description
AgroStar NPK 19:19:19 | 100
g
AgroStar NPK 19:19:19 is a water-soluble fertilizer with
equal declared nitrogen, phosphorus-as-P₂O₅ and potassium-as-K₂O values. It is intended for general crop nutrition and vegetative
development, including branching, green foliage, roots and shoots. This listing is the 100 g pack.
What it supplies: Equal declared N, P₂O₅ and K₂O values of 19% each, not equal
elemental nitrogen, phosphorus and potassium percentages.
Where it fits: General crop nutrition and support for vegetative growth, branching,
foliage, roots and shoots.
Before measuring: Confirm crop, stage, route, product quantity, final water and
treatment basis. Pack weight is not a universal tank or acre dose.
Why Choose This Product? Key Benefits
- 🌿 Equal declared NPK grade: Provides the
stated 19:19:19 nutrient balance as part of the crop’s overall fertilizer programme.
- 🌱 Vegetative-development support: AgroStar
describes nutritional support for branching and green foliage, subject to crop need and conditions.
- 🌾 Root and shoot nutrition: Supports a
nutrition plan for root and shoot development without guaranteeing a fixed growth or yield response.
- 💧 Water-soluble fertilizer: The product is
described as dissolving readily in water for the separately listed spray, fertigation and drench routes.

How It Works: Plant Nutrition
The three grade values describe nutrient supply, not a pesticide
mode of action. Match them to the actual crop requirement and the rest of the fertilizer programme.
- Interpret the grade correctly: 19:19:19 means N, P₂O₅ and K₂O at the declared values. Equal grade numbers do not mean equal
elemental nitrogen, phosphorus and potassium percentages.
- Support vegetative nutrition: AgroStar positions the grade for healthy vegetative development, branching, green foliage and
root/shoot growth. This nutritional purpose does not establish a universal crop stage or a guaranteed response.
- Separate the delivery routes: Foliar spray, fertigation and drenching require different product-and-water, coverage and placement
instructions. Water solubility does not make these programmes interchangeable.
Crop Suitability & Nutrition Purpose
AgroStar describes broad crop suitability. Use it only where the
crop’s nutrient requirement, growth stage, soil and irrigation-water conditions fit the confirmed nutrition
programme.
| Crop / Use | Nutrition Purpose & Conditions |
|---|---|
| General crop nutrition |
|
| Vegetative growth and branching |
|
| Root and shoot development |

Dosage & Application Guide
Obtain complete directions for the chosen crop and route from the
supplied pack and qualified crop advice before preparing a solution. Keep product quantity, water and coverage together; do not use
another 19:19:19 brand to fill in missing directions.
Application Requirements
Foliar spray: Confirm crop and growth stage, the product
quantity for the treated area and matching total spray-water volume. Do not turn an isolated area amount into a per-litre or tank
concentration.
Fertigation or drenching: Confirm which root-zone direction
applies, final water volume, placement or injection method, area and whether the quantity is for one application or a wider programme.
Do not treat concentration and area quantities as interchangeable alternatives.
Timing and further applications: Match vegetative-nutrition
use to crop need and stage. Further applications depend on crop growth and crop life; this is not a fixed interval or an instruction
to repeat automatically.
Pack quantity: The 100 g pack is the sale quantity. Measure
only the amount required for the confirmed crop programme; do not assume that a whole pack belongs in one sprayer or irrigation
tank.
How to Apply: Best Practices
- Check crop need first: Review crop stage, soil-test results and the full fertilizer programme with qualified advice. Green foliage
alone is not proof that the crop needs more fertilizer.
- Choose the correct route: Use complete crop-specific spray, fertigation or drench directions. Confirm product, final water and
coverage before measuring, and do not transfer a foliar direction to the root zone.
- Prepare solutions separately: AgroStar advises against direct chemical mixing. Prepare separate water solutions and combine only
when the proposed mixture and both products’ directions permit it; do not mix dry products or concentrates indiscriminately.
- Respect mixing exclusions: Avoid mixtures with sulphur-, calcium- or lead-containing compounds. General compatibility wording is
not approval for every pesticide, fertilizer or adjuvant.
- Avoid dust and contamination: Work with ventilation, avoid breathing dust or mist, and use suitable protective equipment. Keep
product, surplus solution, spills and washings out of drains and water sources.
- Reassess rather than repeat blindly: Base further applications on crop growth, crop life and nutrition advice. Record route and
amount so the same nutrient supply is not unintentionally duplicated.
Frequently Asked Questions
No. The grade declares nitrogen as N, phosphorus as P₂O₅ and potassium as K₂O. It is an equal declared grade, not three equal elemental percentages.
Do not infer those details from the grade alone. Check the exact supplied pack declaration; this description does not specify individual trace elements, chelation or a nitrogen-form split.
Not automatically. Pack weight is the sale quantity. Confirm crop, stage, route, product amount, final water and treatment basis before measuring; no universal tank or acre recipe is supplied.
AgroStar positions the grade for general nutrition and vegetative development. Match use to crop need and stage. Its frequency guidance depends on crop growth and crop life, not a fixed-day repeat schedule.
No. Avoid sulphur-, calcium- and lead-containing mixing partners and confirm any other combination against both exact directions. Prepare separate water solutions only where the proposed mixture is permitted.
Safety & Disclaimer
Before you use it: Read the current supplied pack and product directions. Match the crop, nutrient
need, grade, stage, application route, product quantity, final water and treatment basis. This overview does not replace the
pack or qualified crop advice and does not guarantee a crop response.
Avoid breathing dust or mist and contact with skin or eyes. Use suitable protective clothing,
chemical-resistant gloves, eye protection and appropriate respiratory protection. Work with ventilation; do not eat, drink or
smoke while handling. Wash exposed skin and washable contaminated clothing after work. Discard clothing or other absorbent
material that is drenched or heavily contaminated.
Store tightly closed in the original pack in a cool, dry, ventilated place away from children, food,
drink and animal feed. Protect from moisture and excessive heat and keep separate from strong oxidizers. Do not leave spills
accessible to animals.
Keep product, spills, surplus solution, washings and packaging out of drains, wells, ponds, streams and
other water sources. Fertilizer contamination can promote algae growth and degrade water quality. Collect spills without
raising dust and use approved local waste arrangements; never reuse empty packs.
If exposure occurs, move away from dust or mist to fresh air. Remove contaminated clothing and wash
affected skin with soap and water. Rinse exposed eyes carefully with clean water and seek medical advice for irritation. After
swallowing or significant symptoms, obtain prompt medical or poison-centre advice with the pack. Do not induce vomiting unless
a medical professional directs it, and never give anything by mouth to an unconscious person.
Do not treat water solubility, a nutrient classification or broad crop suitability as proof of
harmlessness, certified production status, freedom from every impurity or universal mixture compatibility. Follow the complete
supplied crop programme and product-specific precautions.
