PSB Bio Fertilizer Liquid Formulation

PSB contains Bacillus megaterium & Bacillus Polymyxa bacteria which have attracted the attention of agriculturists as soil inoculums to improve the plant growth and yield. When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. The use of PSB 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.


PSB Bio Fertilizer Liquid Formulation 

Mechanism of Action

  • PSB Bio Fertilizer Liquid Formulation
  • These bacteria secrets special acid to dissolve bound phosphorus in soil. This process provide free available phosphorus for crops.


  • PSB solubilizes insoluble phosphate for easy uptake by crops. Reduces 25 to 40% of phosphoric fertilizers cost & PSB Increases the level of available P2O5 in the soil. It also improves the fertility of soil and reduces the use of chemical fertilizers . It is Harmless, Eco-friendly and low cost agro-input. Adds nutrients to the soil / make them available to the crop & secrete certain growth promoting substances. Help the proliferation and survival of beneficial microorganisms in soil. PSB provides most active form of phosphorus solubilizing bacteria and starts functioning immediately after application in soil.


  • Root Dippind: As per the requirement, mix the bio fertilizer in 5-10 litres of water. Later dip the roots of seedlings up to half an hour before transplantation.
  • Soil Application: Add 500 ml of bio fertilizer in 100 litres of water and apply at 1 acre of land through drip irrigation or drench the soil at proper moisture of land.
  • Seed Treatment: Use 10 ml of PSB per 100ml of water mix it with 20 gm sugar/ jaggery for 1 kg of seeds. After being uniformly wet shake them gently to form uniform layer of culture coating. Then dry the seeds in shade for 20-25 minutes.
