Mono-Potassium Phosphate (MKP) 0-52-34 – 4 lb

High-purity mono-potassium phosphate (MKP) is the most concentrated straight fertilizer containing phosphorus and potassium — fully water-soluble, fast-dissolving, and with the lowest salt index (8.4) among known soluble fertilizer salts.

Analysis

• Phosphorus (P₂O₅): 52%
• Potassium (K₂O): 34%
• 1 gram per gallon yields ~60 ppm P and ~75 ppm K

Key Features

• 100% water-soluble — non-hygroscopic, free-flowing, does not cake
• Lowest salt index (8.4) — safe for foliar, seedbeds, transplants, and sensitive crops
• Chloride-free and very low sodium (max 20 ppm Cl, max 50 ppm Na)
• No harmful residues — no clogging of pipes or drippers
• USEPA registered biopesticide — fungicidal activity against powdery mildew
• Nitrogen-free — precise N management in nutrient programs

Ideal Application Methods

• Hydroponic nutrient solutions
• Fertigation: drip, micro-jet, center pivot, sprinklers
• Foliar spray programs (1–3% concentration)
• Starter fertilizer and seedbed applications
• Soluble NPK blends and liquid fertilizer production

Packaging
