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 — MKP
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.
