Nutrient composition and biochemical benefits
The equal 1:1:1 ratio supports comprehensive plant development throughout active growth phases.
- Nitrogen (20% N): Formulated with nitrate, ammoniacal, and urea nitrogen for sustained foliar greening and vigorous vegetative shoots.
- Phosphorus (20% P2O5): Fully water-soluble phosphate that accelerates root branching, energy transfer, and early bud initiation.
- Potassium (20% K2O): High-grade potash that regulates stomatal movement, water balance, enzyme activation, and disease resistance.
- Completely chloride-free and sodium-free formulation, safe for sensitive crops and salinity-prone soils.
Application methods: Fertigation and foliar spray
Highly soluble crystals dissolve without leaving sediment, preventing dripper clogging in micro-irrigation systems.
- Drip Fertigation: Dissolve required quantity in fertilizer tanks or venturi injectors; distribute uniformly through irrigation cycles.
- Foliar Spray: Spray during early vegetative, pre-flowering, and fruit formation stages using a clean knapsack sprayer.
- Ideal for polyhouse crops (capsicum, tomato, cucumber) and commercial orchards (pomegranate, grapes, citrus).
- Compatible with most neutral agrochemicals, but avoid mixing directly with calcium nitrate or concentrated sulfur in the same tank.
Safe handling and soil fertility tips
Combining water-soluble fertilizers with soil testing ensures maximum economic returns.
- Base application frequency on crop growth stage and periodic soil and leaf nutrient analysis.
- Apply during morning or late afternoon hours to prevent foliar salt scorch under hot midday sun.
- Store fertilizer bags in a dry, cool warehouse to prevent moisture absorption and caking.

Common questions
What does 20-20-20 mean on a fertilizer bag?
It indicates that the fertilizer contains 20% Total Nitrogen (N), 20% Available Phosphate (P2O5), and 20% Soluble Potash (K2O) by weight.
Can 20-20-20 fertilizer be applied through drip systems?
Yes, high-grade NPK 20-20-20 is 100% water-soluble and formulated specifically for drip fertigation without clogging emitters.
When is the best time to apply NPK 20-20-20?
It is best applied during active vegetative development and pre-flowering stages when crops require balanced nutrition for roots, shoots, and blooms.
