The Pure Microbial Company

Phosphorus solubilizer / Potassium mobilizer

PK-FORCE™ is a two-in-one, exclusive proprietary bio-inoculant that solubilizes phosphate and mobilizes potassium by producing enzymes and organic acids that break down phosphate and potassium, then release them in ionic plant-utilizable forms. It puts microbes back into the soil to help restore its biology for long-term sustainability, which means the soil retains more nutrients naturally, reducing the chance of deficiencies and making phosphate, potassium, and other micronutrients available to plants throughout all stages of growth.

PK-FORCE™ selective and efficient consortium of microbes works in unison to improve soil fertility, promote root growth, and a larger leaf area while enhancing yield potential.

Unlocking Phosphate Availability

Phosphorus (P) is one of the three main macronutrients required in relatively large amounts for optimal plant growth and reproduction. Its functions cannot be replaced by any other nutrient, and P has low availability in soils due to slow diffusion and high fixation, making it a growth-limiting nutrient. This is one reason why the agriculture sector heavily relies on chemical fertilizers as a phosphorus source and to maximize productivity, but this causes numerous environmental problems. Smart Microbes understands the P dynamics and PK-FORCE™ provides a sustainable solution that will help improve agricultural phosphorus availability.


  • Increases nutrient phosphorus and potassium availability and uptake by plants
  • Encourage fast root development and vegetative growth
  • Improves plant vigor, health, and productivity
  • Increases micronutrients availability to plants from the soil
  • Improves plant strength and the ability to tolerate unfavorable environmental conditions
  • Aids in photosynthesis and food formation

Key Advantages

  • Reduces up to 50% or more chemical fertilizer requirements
  • Used to treat seeds, plantlets and grown plants which decreases the need for additional agricultural inputs.
  • Promotes the healthful growth of seeds and crops making them more marketable.
