When it comes to achieving optimal plant health and maximizing crop yields, the quality of your nutrient solution matters. Potassium Phosphate Monobasic MKP CAS 7778-77-0 plays a pivotal role in modern agriculture and hydroponic systems. This highly soluble compound offers essential potassium (K) and phosphorus (P), two macronutrients vital for plant development, root strength, and flower production. Whether you’re a home gardener or a commercial grower, understanding MKP and its benefits can elevate your growing game Potassium Phosphate Monobasic MKP CAS 7778-77-0.

Let’s dive into what makes this compound so important in nutrient solutions.


What is Potassium Phosphate Monobasic (MKP)?

Potassium Phosphate Monobasic (MKP), with the chemical formula KH₂PO₄, is a white crystalline salt used as a water-soluble fertilizer. Known by its CAS number 7778-77-0, MKP provides:

  • 52% Phosphorus (as P₂O₅)
  • 34% Potassium (as K₂O)

It’s free from chlorine and sodium, making it safe for delicate plants and hydroponic systems.

Key Properties:

  • Highly water-soluble
  • pH buffering capability
  • Low salt index (safe for young or sensitive crops)
  • Compatible with most fertilizers

Why MKP is Essential in Nutrient Solutions

1. Supplies Critical Macronutrients

Plants require phosphorus for:

  • Root development
  • Seed and flower formation
  • Energy transfer (ATP synthesis)

They need potassium for:

  • Regulating water uptake
  • Enhancing disease resistance
  • Strengthening plant structure

MKP delivers both in one convenient, balanced compound.

2. Ideal for Hydroponic and Fertigation Systems

Because MKP CAS 7778-77-0 is completely soluble and leaves no residue, it’s a favorite in:

  • Hydroponic growing systems
  • Drip irrigation setups
  • Foliar sprays

Its low electrical conductivity reduces the risk of salt buildup, which can be harmful to sensitive root systems.

3. Encourages Flowering and Fruiting

When used during the blooming phase, MKP promotes:

  • More flower buds
  • Stronger fruit set
  • Increased sugar content in fruits

For this reason, it’s widely used in vineyards, orchards, and flowering crops like tomatoes, peppers, and strawberries.


How to Use Potassium Phosphate Monobasic (MKP) Effectively

Application Methods

1. Fertigation (Drip Irrigation):

  • Use 0.5–2.0 g/L depending on crop stage and need.

2. Foliar Spray:

  • Mix 5–10 g per 10 liters of water.
  • Apply during early morning or late afternoon for best absorption.

3. Hydroponics:

  • Add MKP based on nutrient solution formulas (usually 0.1–0.3 g/L).

Best Practices

  • Always dissolve completely before mixing with other nutrients.
  • Avoid combining with calcium or magnesium in the same tank.
  • Store MKP in a cool, dry place to maintain its potency.

Advantages of Potassium Phosphate Monobasic (MKP) CAS 7778-77-0

Here are the top reasons why MKP stands out among nutrient additives:

  • High purity and solubility
  • Chloride-free – safe for all crops
  • Boosts flower and fruit production
  • Compatible with most crop schedules
  • Excellent for precision agriculture

Whether you’re growing leafy greens, fruiting plants, or ornamentals, Potassium Phosphate Monobasic (MKP) CAS 7778-77-0 ensures your crops get the vital nutrients they need—at the right time.


Who Uses MKP?

This fertilizer is used by a wide range of growers, including:

  • Hydroponic farmers
  • Greenhouse operators
  • Orchard managers
  • Floriculturists
  • Commercial crop producers

Thanks to its clean profile and versatility, MKP is a trusted solution across multiple sectors of the agricultural industry.


Environmental & Safety Notes

  • MKP is non-toxic to humans and animals when used as directed.
  • Its low salt index means less risk of soil salinization.
  • Being free from harmful heavy metals and contaminants makes it eco-friendly.

Still, always follow safety guidelines during handling—use gloves and store away from children or pets.


Conclusion: Why You Should Consider MKP in Your Nutrient Plan

In summary, Potassium Phosphate Monobasic (MKP) CAS 7778-77-0 is a powerful and efficient way to provide essential phosphorus and potassium to your plants. Its high solubility, versatility in application, and effectiveness in promoting growth make it a staple for serious growers.
