Nutrient composition and physical properties
- Contains 52% Phosphate (P2O5) and 34% Potash (K2O), completely free from nitrogen, chloride, sodium, and heavy metals.
- Boasts high water solubility and a low salt index, ensuring safe plant uptake without causing leaf scorch or root burn.
- Moderately acidic pH in solution improves micronutrient availability in alkaline soils and prevents emitter clogging in drip systems.
Crop benefits and critical application stages
- Pre-flowering and flowering: High phosphorus content promotes vigorous root development, floral bud differentiation, and bloom retention.
- Fruit setting and grain filling: High potassium content facilitates carbohydrate translocation, increasing fruit size, sweetness (Brix), and grain weight.
- Disease resistance: Foliar sprays help suppress powdery mildew development in crops like grapes, mango, and cucurbits.
- Applied in fruits (pomegranate, grapes, citrus), vegetables (tomato, capsicum), and field crops (cotton, sugarcane).
Application methods and dosage guidelines
- Drip fertigation: Administer through irrigation lines during reproductive and fruit development stages.
- Foliar spray: Dissolve in clean water and spray during early morning or late afternoon hours.
- Compatible with most water-soluble fertilizers and registered crop protection chemicals, but avoid mixing directly with calcium or magnesium salts.

Common questions
What is NPK 00:52:34 fertilizer?
It is Monopotassium Phosphate (MKP), a water-soluble fertilizer containing 52% phosphorus and 34% potassium.
Why does NPK 00:52:34 contain zero nitrogen?
Zero nitrogen prevents unwanted vegetative growth, channeling plant energy into flowering, fruit sizing, and sugar accumulation.
When should NPK 00:52:34 be applied to crops?
Apply during flowering bud formation, fruit set, and grain filling stages.
Can NPK 00:52:34 be mixed with calcium fertilizers?
No, mixing phosphate fertilizers directly with calcium forms insoluble calcium phosphate precipitates that clog emitters.
