Bio Fertilizer Water Soluble Formulation

PSB Water Soluble


Bio Fertilizer Water Soluble Formulation

PSB Water Soluble contains Bacillus megaterium & Bacillus Polymyxa bacteria which have attracted the attention of agriculturists as soil inoculums to improve the plant growth and yield. When phosphate solubilising bacteria is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. The use of phosphate solubilising bacteria as inoculants increases Phosphorus uptake by plants. The phosphate solubilizing bacteria (PSB) which solubilizes the inorganic soil phosphates of calcium and iron through production of several organic acids, hydroxyl and carboxyl groups, and chelating them to the bound phosphates and the available calcium.

Mechanism of Action

PSB (phosphate solubilising bacteria) produces soluble phosphate in range of 30 to 40 kg/ha. Whenever phosphoric fertilizers are applied in soil its large quantity gets fixed as Tri-Calcium Phosphate.
As it is water insoluble, it becomes unavailable to crops. Due to phosphate solubilizing bacteria soil microorganisms having inherent capacity to dissolve part of this fixed phosphorus, makes it available to the crops.
This enables converting insoluble phosphate compound in soluble form by secreting certain organic acids.


1. It fixes the atmospheric nitrogen and makes it available to crop.
2. It increases number & length of roots and shoots.
3. It also improves the fertility of soil and reduces the use of chemical fertilizers. It is Harmless, Eco-friendly and low cost agro-input.


Soil Application: Apply 1 Kg Bio-Fertilizer For 1 Acer Land


Sugarcane Plants, Sweet Potato, Sweet Sorghum.

PSB Formulation is a product that contains Phosphate Solubilizing Bacteria (PSB) in a formulation. PSB are beneficial microorganisms that solubilize insoluble phosphorus in the soil, making it available for plant uptake. This water-soluble formulation allows for easy mixing and application, ensuring effective delivery of the PSB to plants and soil.

Three important points about PSB Bio Fertilizer Formulation are:

  1. Contains Phosphate Solubilizing Bacteria (PSB).
  2. Formulated as a water-soluble product for convenient application.
  3. Enhances phosphorus availability for plants.

PSB Formulation is generally safe for plants and the environment when used as directed. It contains beneficial microorganisms that occur naturally in the soil and contribute to soil health. However, it is important to follow the specific instructions provided by the manufacturer and avoid over-application. Conduct small-scale tests and consult with experts for specific crop and application recommendations.

PSB Formulation can be used for various types of plants, including but not limited to:

  • Crops: Such as grains, vegetables, fruits, and legumes.
  • Ornamental plants: Including flowers, shrubs, and trees.
  • Horticultural plants: Such as herbs, potted plants, and greenhouse crops.
