Nutrient grade and chemical composition
- 50% Potash (K2O): Supplies highly concentrated potassium essential for carbohydrate synthesis, stomatal water regulation, and enzymatic activation.
- 17.5% Sulphur (S): Delivered in readily accessible sulphate (SO4²⁻) form for immediate root absorption, vital for plant protein synthesis and oil formation.
- Zero chloride: Near-zero salt index and virtually chloride-free, preventing leaf margin burn in sensitive horticultural crops like grapes, pomegranate, banana, and potato.
- Complete water solubility: Dissolves rapidly without leaving gritty residue, making it ideal for drip fertigation and precision foliar sprays.
Critical application stages and crop responses
Apply during the reproductive, fruit enlargement, and maturity stages when plant demand for potassium peaks. In commercial fruits and vegetables, applying 00:00:50 enhances fruit diameter, accelerates uniform rind coloring, increases Total Soluble Solids (TSS / Brix sweetness), improves fruit firmness, and extends post-harvest shelf life during transport.
Application dosage and fertigation guidelines
- Foliar spray: Typically applied at 5 to 10 grams per liter of water (1 to 2 kg per acre in 200 liters of water) during fruit swelling and color break.
- Drip fertigation: Injected through venturi systems at 2 to 5 kg per acre per application, tailored according to crop fertigation schedules.
- FCO compliance: Complies with 100% water-soluble fertilizer standards under the Fertilizer (Control) Order.

Common questions
What nutrients are supplied by NPK 00:00:50 fertilizer?
It supplies 50% water-soluble Potash (K2O) and 17.5% available Sulphur (S), with zero nitrogen and zero phosphorus.
Why is 00:00:50 preferred over MOP (Muriate of Potash 00:00:60) for fruit crops?
Unlike MOP which contains 45% chloride, 00:00:50 is virtually chloride-free, preventing toxic salt accumulation and leaf burn in sensitive fruits and vegetables.
When is the best time to apply NPK 00:00:50 to crops?
During the fruit sizing, grain filling, and maturity stages to improve fruit weight, sugar content, color, and shelf life.
