Nutrient Composition and Chemical Quality
A 1:1:1 balanced NPK ratio supplies all three essential primary plant nutrients in equal measure, preventing vegetative-reproductive nutritional imbalances.
Manufactured from high-purity technical-grade raw materials, it dissolves completely in water without leaving insoluble grit that could clog drip emitters or spray nozzles.
- Total Nitrogen (20% N): Formulated with nitrate, ammoniacal, and amide nitrogen for both immediate and sustained vegetative uptake
- Available Phosphate (20% P2O5): 100% water-soluble phosphate stimulating root branching, tillering, and early flower bud differentiation
- Soluble Potash (20% K2O): Enhances carbohydrate translocation, enzyme activation, and drought tolerance during rapid growth flushes
- Low Salt Index: Free from harmful chlorides and heavy metals, minimizing the risk of foliar leaf scorch or soil salinity
Crops and Critical Application Stages
Balanced 20-20-20 is ideal during the mid-vegetative, active branching, and early flowering stages when plants require balanced nutrient replenishment.
It is widely used in protected polyhouse horticulture, open-field commercial vegetables, and fruit orchards.
- Vegetables (Tomato, Chilli, Brinjal): Foliar spray during active branching and flowering flushes to support canopy and blossom health
- Fruit Orchards (Pomegranate, Citrus, Grapes): Applied through drip systems during new spring flush and early fruit set
- Cotton and Sugarcane: Drip fertigation during rapid vegetative establishment and node elongation stages
- Greenhouse Floriculture: Routine fertigation formula maintaining balanced rose, gerbera, and carnation stem growth
Foliar Spray and Drip Fertigation Guidelines
For foliar sprays, dissolve 4 to 5 grams per liter of clean water (approx. 800 g to 1 kg per acre in 200 liters).
For drip irrigation, inject dissolved fertilizer during the middle third of the irrigation cycle, flushing drip laterals with clean water afterward.
- Water Solubility: 100% water-soluble; dissolve completely in a primary bucket before tank injection
- Timing: Early morning or late afternoon foliar application maximizes stomatal absorption before hot midday winds
- Tank-Mix Compatibility: Compatible with most chelated micronutrients; avoid mixing directly with concentrated calcium nitrate in the same mother tank

Common questions
What does NPK 20-20-20 mean?
It indicates that the fertilizer contains 20% total nitrogen (N), 20% available phosphorus (P2O5), and 20% soluble potassium (K2O) by weight.
Can NPK 20-20-20 be used in drip irrigation systems?
Yes, water-soluble 20-20-20 is specially manufactured for drip fertigation and will not clog drip emitters.
What is the recommended dose for foliar spraying of 20-20-20?
The general recommendation is 4 to 5 grams per liter of water (approx. 800 g to 1 kg per acre in 200 liters of water).
