Nutrient Composition and 100% Water Solubility
NPK 19-19-19 is manufactured from high-purity technical grade nutrient salts with zero insoluble sediments.
It supplies equal proportions of nitrogen, phosphorus, and potassium, providing foundational nutrition for crop vegetative establishment.
Because it dissolves completely in water, it flows cleanly through drip emitters without risk of clogging.
- Total Nitrogen (19%): Supplies balanced ammoniacal, nitrate, and amide nitrogen forms
- Water-soluble Phosphate (19%): Readily available orthophosphate driving early root and shoot expansion
- Water-soluble Potash (19%): Balances plant water turgor, activates enzymes, and strengthens stems
Crop Suitability and Application Practices
NPK 19-19-19 is suited for all crops during early vegetative branching, tillering, and shoot expansion stages.
Applying through drip fertigation or high-volume foliar spray provides immediate plant-available nutrition during rapid growth.
- Drip fertigation: Injected via venturi or fertilizer tanks at recommended concentrations per irrigation cycle
- Foliar spray: Applied at low foliar concentrations during periods of high nutrient demand
- Crops: Widely used in vegetables, cotton, sugarcane, pulses, and commercial fruit orchards
Storage, Quality Checks, and Soil Health
Store bags in dry, covered godowns protected from ambient moisture absorption.
Purchasers should verify official FCO quality marks and batch specifications from certified cooperative societies and authorized retail fertilizer dealers.
Coordinate applications with recommendations from Soil Health Card tests for balanced nutrition.
- Moisture protection: Reseal opened bags tightly to prevent hygroscopic clumping
- Soil test alignment: Coordinate fertilizer scheduling with soil nutrient recommendations from the Soil Health Card portal
- Quality verification: Ensure FCO compliance marks on commercial bags purchased from authorized dealers
