The familiar MKP designation 0-52-34 normally expresses phosphate and potash on oxide-equivalent bases. If a formulation uses elemental phosphorus and potassium, convert each separately and label the result.
Use a real producer analysis as context
Haifa’s MKP page describes its product as 52% P2O5 and 34% K2O. These are that product’s stated values, not an ENVO guarantee. Use the offered grade’s actual analysis for a purchase or formulation.
With rounded stoichiometric factors of 0.4364 for P from P2O5 and 0.8301 for K from K2O, a hypothetical 100 kg material at that analysis contributes approximately 22.69 kg elemental P and 28.22 kg elemental K. These are reporting conversions, not a recommended crop dose.
| Expression per illustrative 100 kg | Converted expression |
|---|---|
| 52 kg P2O5 equivalents | 52 × 0.4364 ≈ 22.69 kg P |
| 34 kg K2O equivalents | 34 × 0.8301 ≈ 28.22 kg K |
| 0 nitrogen in the stated analysis | No N contribution under that stated analysis |
Do not double-count the same nutrients
P and P2O5 equivalents describe the same phosphorus contribution on different bases. The same applies to K and K2O equivalents. Do not add both to one nutrient total or interpret the oxide-equivalent names as evidence of free oxides in the fertilizer.
Have a qualified specialist set the complete nutrient programme. Send ENVO the required MKP analysis and the reporting basis used in your formulation. A controlled ledger makes comparisons with other nutrient sources useful without confusing percentage conventions with a new performance claim.
