MKP — Soluble Phosphorus & Potassium for Precision Fertigation
Mono potassium phosphate delivers phosphorus and potassium without nitrogen — essential during flowering and fruit set when nitrogen input must be restricted to avoid vegetative growth at the expense of yield. The 52% P2O5 and 34% K2O analysis dissolves completely at 1% concentration with pH 4.3–4.7, acidifying the nutrient solution slightly and improving micronutrient availability. From 200 MT.

Application Notes
MKP is the standard P+K source in greenhouse A/B tank systems during reproductive stages. Typical injection rate: 0.5–1.5 mmol/L P depending on crop. Avoid mixing MKP stock solution with calcium sources — use separate injection lines. Shipped in 25 kg bags and 1,000 kg big bags for commercial greenhouse and orchard fertigation.
FAQ
When should MKP replace MAP or DAP in fertigation?
Switch to MKP at first flower appearance in tomato, pepper and melon crops. The zero-nitrogen formula prevents excessive vegetative growth during the yield-critical reproductive phase while maintaining phosphorus and potassium supply.
Does MKP's acidic pH affect drip system components?
At working dilutions (0.1–0.5%), MKP's acidity is negligible for PVC and PE drip lines. In concentrated stock tanks at 10%+, use corrosion-resistant fittings and monitor pH before injection.
Can MKP be applied as a foliar spray?
Yes. Foliar MKP at 0.5–1.0% concentration during flowering improves pollen viability and fruit set in tree crops. Apply in early morning when stomata are open for maximum absorption.
