Mono-Potassium Phosphate (NPK 0-52-34):
Mono-Potassium Phosphate (MKP) is a fully water-soluble, high-purity specialty fertilizer containing 52% Phosphorus (P₂O₅) and 34% Potassium (K₂O). It is a nitrogen-free fertilizer, making it the ideal choice for the reproductive phase of crop growth (flowering and fruiting) when plants require high levels of P and K but lower Nitrogen to prevent excessive vegetative growth. Its low salt index and acidic pH make it safe for sensitive crops and helpful in preventing the clogging of drip irrigation systems.
Mode of Action:
MKP 0-52-34 functions through rapid systemic absorption and physiological regulation:
Systemic Absorption: Being 100% water-soluble, it is instantly available to the plant through both leaves (foliar) and roots (fertigation).
Energy & Sugar Transport:
Phosphorus (52%): Acts as the plant's "energy currency" (ATP), vital for flower induction, root development, and seed formation.
Potassium (34%): Regulates stomatal opening, water balance, and enzyme activation. Crucially, it facilitates the transport of sugars from leaves to the developing fruit, enhancing size, weight, and sweetness.
Disease Resistance: The combination helps thicken cell walls and improves the plant's natural resistance to pests and diseases, particularly fungal infections like powdery mildew.
Primary Uses and Target Crops:
This fertilizer is specifically used to boost flowering, fruit setting, and overall produce quality (color, luster, taste).
Key target crops include:
Fruits: Grapes, Pomegranate, Banana, Mango, Citrus, Apple, Strawberry, Watermelon
Vegetables: Tomato, Potato (for tuber size), Onion, Chili, Capsicum, Cucurbits
Flowers: Roses, Carnations, Gerbera (for longer shelf life and brighter colors)
Field Crops: Cotton, Sugarcane (for sugar accumulation), Pulses
Application and Dosage:
Mono-Potassium Phosphate is suitable for foliar spray and fertigation.
The recommended dosage varies depending on the crop stage (typically applied post-flowering to fruit maturity):
Foliar Spray: Dissolve 3 to 5 grams per liter of water. Apply during fruit setting and fruit development stages to improve size and quality.
Fertigation (Drip): Apply 3 to 5 kg per acre. This is effective for promoting root growth in early stages or fruit filling in later stages.
Fungal Control: In some crops like grapes and powdery mildew-prone plants, a foliar spray of MKP can help suppress fungal growth.
Compatibility: It is compatible with most pesticides and fertilizers but must NOT be mixed with Calcium (Ca) or Magnesium (Mg) fertilizers, as this will cause precipitation.
Target Benefits / Deficiency Correction:
Unlike pesticides, this product targets growth stages and quality parameters.
Key benefits include:
Fruit Quality: Significantly increases fruit size, weight, sugar content (Brix), and color intensity.
Maturity: Promotes uniform ripening of fruits.
Flowering: Prevents flower and fruit drop.
Disease Suppression: Helps suppress powdery mildew when applied as a foliar spray.
Root Growth: Excellent for root development when nitrogen application must be restricted.
Safety Precautions:
Standard safety practices for chemical fertilizers should be followed.
Key safety recommendations include:
Personal Protective Equipment (PPE): Wear gloves, goggles, and a mask when handling the powder to avoid skin and eye irritation.
Mixing: Add the powder to water (not water to powder) and agitate until dissolved. Do not mix with Calcium Nitrate or Magnesium Sulfate.
Handling Practices: Wash hands thoroughly with soap and water after handling. Do not eat, drink, or smoke during application.
Environmental Safety: Do not apply directly to water bodies.
Storage:
Store the product in its original container in a cool, dry, and well-ventilated place. The product is hygroscopic (absorbs moisture from the air), so the bag must be kept tightly sealed when not in use to prevent caking. Keep away from direct sunlight, food, and animal feed.
