Item description
AgroStar NPK 13:40:13 (TE) | 25
kg
AgroStar NPK 13:40:13 is a water-soluble fertilizer with a
higher declared phosphorus value than nitrogen or potassium. It is intended for crop nutrition, including starter and
root-development programmes and nutritional support during flowering and fruit development. This listing is the 25 kg
pack.
What it supplies: The 13:40:13 grade expresses nitrogen, phosphorus as P₂O₅ and
potash as K₂O. It is not an equal-proportion NPK feed.
Where it fits: Starter and root-development nutrition, and programmes that need
relatively more phosphorus around flowering and fruit development.
Before measuring: Confirm the crop, growth stage, route, product amount, water and
treatment basis. Pack weight is not a universal tank or acre dose.
Why Choose This Product? Key Benefits
- 🌱 Starter nutrition: AgroStar positions the
higher-phosphorus grade for root development where the crop programme calls for it.
- 🌼 Flowering-stage support: Supports the
nutritional programme around flowering, early fruit formation and fruit development without guaranteeing a particular crop response.
- 💧 Water-soluble fertilizer: The product is
described as dissolving readily in water for the separate spray, fertigation and drench routes.
- 🌿 NPK contribution: Supplies the declared
nitrogen, phosphorus and potash values as part of the crop’s overall nutrition plan, rather than replacing every nutrient requirement.

How It Works: Plant Nutrition
The grade describes nutrient supply, not a pesticide mode of
action. Choose it for an identified crop-nutrition need and account for nutrients already supplied by other
fertilizers.
- Read the nutrient basis correctly: 13:40:13 means nitrogen as N, phosphorus expressed as P₂O₅ and potash expressed as K₂O. Do not
describe the latter two figures as elemental phosphorus and potassium.
- Match the phosphorus emphasis: The declared phosphorus value is higher than the nitrogen and potash values. AgroStar positions this
grade for root development and nutrition around flowering and fruit formation; it is not an equal-ratio 19:19:19 grade.
- Keep delivery routes distinct: A foliar spray, fertigation application and root-zone drench each need their own product amount,
final water volume and treatment basis. Water solubility does not make those directions interchangeable.
Crop Suitability & Nutrition Purpose
AgroStar describes broad crop suitability. Match use to the crop’s
nutrient requirement, growth stage, soil-test results and irrigation-water conditions rather than treating all crops as one
application programme.

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; another
manufacturer’s 13:40:13 directions must not fill in missing details.
Application Requirements
Foliar spray: Confirm the crop and growth stage, product
quantity for the treated area and matching total spray-water volume. Do not turn an isolated area rate into a per-litre or tank
recipe.
Fertigation or drenching: Confirm which root-zone direction
applies, final water volume, placement, treatment area and whether the quantity is for one application or a wider programme. A
concentration and an area amount are not interchangeable alternatives.
Timing and further applications: Match starter, flowering
or fruit-development nutrition to the actual crop and need. Further applications depend on crop growth and crop life; this is not a
fixed-day repeat schedule.
Pack quantity: The 25 kg 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
- Assess the crop first: Review crop stage, soil-test results and the full fertilizer programme. Do not diagnose every low-growth or
flower-drop symptom as a phosphorus shortage.
- Choose the correct route: Use the supplied crop-specific spray, fertigation or drench directions. Confirm product, final water and
coverage before measuring; do not transfer a foliar instruction 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 appropriate protective equipment. Keep
spills, surplus solution and washings out of drains and water sources.
- Reassess rather than repeat automatically: Base further use 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 declared phosphorus value is higher than the nitrogen and potash values. The figures mean N, P₂O₅ and K₂O, not three elemental nutrient percentages.
Check the exact supplied pack declaration. This description does not specify individual trace elements, their percentages or chelation, and the TE wording must not be treated as a substitute for that information.
Not automatically. Pack weight is the sale quantity. Confirm crop, stage, route, product quantity, water and treatment basis before measuring; no universal tank or acre recipe is supplied.
AgroStar positions it for starter and root-development nutrition and support around flowering and fruit formation. Choose the stage from the complete crop programme; flower drop has multiple causes and no crop response is guaranteed.
No. Avoid sulphur-, calcium- and lead-containing mixing partners and confirm every other mixture. This is a fertilizer, not an insecticide or fungicide, and it does not replace a pest-management programme.
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.
