Potash Solublizing Bacteria

A versatile biofertilizer containing potash solubilizing bacteria. It converts insoluble potash present in the soil into soluble form in majority soils

(pH 5 to 11). Microbes mobilize potash and make them available to plants.. It helps to regulate the activity of biological process in the plant & improves overall metabolism in plants..  These changes help in the formation of food materials like carbohydrates, proteins etc.  This results into chlorophyll synthesis, disease resistance, & higher quality yields. This microbes helps in easy uptake of the minerals.Potassium is one of the major plant nutrients. K is present in the soil but mostly it’s fixed and unavailable for plant root uptake. The application of chemical fertilizers has an adverse effect on soil health. Fertilizers based on microbes called microbial fertilizers. Microbial fertilizers are the best alternatives source for chemical fertilizers. They provide nitrogen, potassium to the plant. This is the most sustainable way of providing K to plant nutrition.

Mode of action

Phosphorous solubilizer microbes produce extra cellular enzymes and organic acids, which solubilizes chemically and biologically fixed phosphorous. This phosphorous is available for plant roots in soil.

Method of Use & Dose

Drenching (Fertigation/ Drip irrigation): Mix 5 ml PSB in 1 litre of water and drench in the root zone. (2-                                                                3 lit/acre by drip irrigation system)

With compost : Mix 3 lit PSB in compost and spread over a one-acre area.

Seed Treatment : Use 25-50 ml PSB to coat 1 kg seed

Seedling treatment (Root dipping) : Mix 5 ml PSB in 1 litre of water and use this water for root dipping.


Avoid using under direct sunlight.

Avoid using alkaline or acidic pH products.

Do not use in combination with chemical pesticides and fertilizer
