OK- PSB Phosphate solubilizers (Bacillus megaterium var. phosphaticum ) dissolve fixed phosphate into plant utilizable form. Phosphate solubilizers produce organic acids (viz, citric acid, succinic acid, lactic acid, etc.), hormones (viz, indole acetic acid, gibberellins etc.) and enzymes (viz, phytase, nuclease, lecithinase etc.) that help, in solubilisation of insoluble phosphates into plant utilizable form. 

Soil Application
OK- PSB Apply 1 Liter/acre (or) 2 kgs of powder after mixing it thoroughly in well decomposed organic matter, can be applied as band placement / side dress application at the time of planting or during early stages of the cropping.

Preparation of Spray Solution                                                                                                                                                                                                  Suspend OK- PSB (@1 Liter/acre (or) 2 kgs of powder) in a clean dry container and add water (20 Liters). Stir the contents well and make up to the final spray volume (500 Liters) with water.

Seed Treatment (100 ml (or)  500 gms OK-PSB ) Seed required for 1 hectare is to be treated with OK-PSB by adopting either seed dipping or seed coating methods. Use of the respective inoculum properly and instant sowing of the inoculated seeds with minimal waiting period between treatment and sowing are necessary for greater effectiveness.
