    🌿 Monopotassium Phosphate (MKP) – High-Purity Fertilizer for Optimal Crop Nutrition

    Product Name: Monopotassium Phosphate
    Chemical Formula: KH₂PO₄
    CAS Number: 7778-77-0
    Appearance: White crystalline powder
    Grade: Fertilizer / Technical / Food Grade (specify as needed)
    Packaging: 25 kg bags or customized upon request
    Solubility: Fully water-soluble
    Purity: ≥ 99%


    🧪 Product Description:

    Monopotassium Phosphate (MKP) is a highly efficient source of phosphorus and potassium, two essential nutrients required for healthy plant growth and optimal crop yield. It contains 52% phosphorus (P₂O₅) and 34% potassium (K₂O), making it one of the most concentrated and balanced fertilizers available.

    Thanks to its high solubility and chloride-free composition, MKP is ideal for all crop types and especially suitable for foliar feeding, fertigation, hydroponics, and drip irrigation systems. It is widely used during critical growth stages such as root development, flowering, and fruiting, providing rapid nutrient uptake to support stronger plant health and productivity.


    🌱 Benefits of Monopotassium Phosphate (MKP):

    • 📈 Boosts Flowering & Fruiting: Encourages early bloom and improves fruit set and development.

    • 💧 Fully Water-Soluble: Dissolves easily without residue for efficient fertigation and foliar application.

    • 🚫 Chloride-Free: Safe for sensitive crops like grapes, berries, and ornamentals.

    • 🌾 Supports Root Development: High phosphorus content enhances root growth in early plant stages.

    • 🌿 Improves Crop Quality: Promotes better size, color, and shelf life of fruits and vegetables.

    • 🔄 Compatible with Most Fertilizers: Can be used in combination with other fertilizers (except calcium-containing ones).


    📦 Recommended Applications:

    • Foliar Spray: 1–3 g/L water

    • Fertigation: 5–10 kg/ha per application depending on crop and soil conditions

    • Hydroponics: Tailored nutrient formulations including MKP for precise feeding


    Monopotassium Phosphate (MKP) is trusted by farmers, gardeners, and agronomists for delivering consistent results and healthier, more productive crops. Add it to your nutrient program and watch your plants thrive!
