Nutrient profile and biochemical advantages
The unique combination of water-soluble phosphorus and potassium supports critical reproductive phases.
- Available Phosphate (52% P2O5): Stimulates root elongation, energy storage (ATP synthesis), and uniform flower bud differentiation.
- Soluble Potash (34% K2O): Regulates stomatal conductance, activates enzymatic processes, and enhances fruit weight, sugar content, and color.
- Zero Nitrogen (0% N): Ideal when vegetative vine growth is excessive or during cold periods when nitrogen induces fungal vulnerability.
- Chloride and Sodium Free: Low salt index makes it safe for sensitive greenhouse crops and saline-prone soils.
Application stages and methods
MKP dissolves rapidly in water without leaving residues, making it ideal for micro-irrigation systems.
- Drip Fertigation: Applied through drip irrigation tanks or venturi injectors during flowering and fruit setting stages.
- Foliar Feeding: Applied as a fine foliar spray during early morning or late evening hours at flowering initiation and fruit sizing.
- Orchards (Grapes, Pomegranate, Citrus): Promotes cane maturity, flower cluster retention, and uniform fruit ripening.
- Vegetables (Tomato, Chilli, Capsicum): Enhances fruit firmness, reduces blossom drop, and improves marketable yield grade.
Compatibility and handling guidelines
Correct tank mixing prevents precipitate formation and emitter blockages in irrigation systems.
- Compatible with most neutral agrochemicals and water-soluble fertilizers.
- Do not mix directly with calcium-based fertilizers (like Calcium Nitrate) or magnesium sulfate in concentrated stock tanks.
- Store bags in a cool, dry place elevated on wooden pallets to prevent moisture absorption.
- Base total application rates on soil fertility tests and crop nutrient removal guidelines.

Common questions
What does 00-52-34 stand for in fertilizer terminology?
It indicates 0% Total Nitrogen, 52% Available Phosphate (P2O5), and 34% Soluble Potash (K2O) by weight.
Why is 00-52-34 applied instead of balanced 19-19-19 during flowering?
Balanced fertilizers supply nitrogen which promotes leafy growth, whereas 00-52-34 supplies only phosphorus and potassium to maximize flower retention and fruit development.
Can 00-52-34 be mixed with Calcium Nitrate in the same tank?
No, mixing phosphate fertilizers directly with calcium creates insoluble calcium phosphate precipitates that clog drip emitters; apply them through separate tanks.
