Biophosol Phosphate Solubilising Bacteria

Listing ID #759675

Biophosol (bio-fertilizer)
phosphate solubilising bacteria (psb)
what is biophosol? : biophosol is a unique liquid and powder based formulation containing various microbes useful for phosphorus solubilization. Phosphate solubilizers 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.
active ingredient: selective strains of phosphate solubilising bacteria (psb)
why biophosol? : up to 40 to 50 percent of p2o5 (phosphorus pent oxide) after separating from phosphatic fertilizer, became unavailable due to formation of bond (salt) with cation like zn, ca, mg, fe etc. Microbes of biophosol release various enzymes which break bond between cation (viz, ca, mg, fe) and p2o5 and make p2o5 free for consumption by plants. By this, cost of application of phosphatic fertilizer is reduced. Microbes also release p2o5 deposited previously applied fertilizer.
mostly farmer uses dap as a prophetic source. As we apply dap it get dissolve and liberate p2o5. These p2o5 have negative valiancy so remain negatively charge. In soil there are so many positive charged elements are present like zn, cu, fe, ca etc. So positive and negative get attracted and make fix bond. These bonds become unavailable to plant and thus p2o5 converts into salt. Day by day these salts get deposited and soil becomes hard. When psb microbes incorporated in soil, they release various organic acids which break this bond between positive negative and make p2o5 available to plants.
recommendation:
soil application: mix 3 to 5 kg1 liter biophosol in 50 kg farm yard manure and apply to one acre field before sowingtransplanting.
seed treatment: mix 250 gram100ml biophosol in 250 ml of molten and cooled slurry prepared by adding small lump of jaggary and mix to seeds required for one acre. Dry in shade for 15-30 minutes before sowing. 250gm100ml biophosol is sufficient for 10-15 kg seeds.
seedlingsetsrhizomes treatment: mix 1 kg500ml of biophosol in 50 liters of water in a container and dip the seedlingsettsrhizomes for 30 minutes before transplanting in one acre.
drenching: mix 1kg1liter of biophosol in 200 liters water and use for drenching soil near the root zones of crop in one acre area.
soil application for nursery: in 1 kg cow dung or compost add 10ml25 gm biophosol and spread it to nursery
main crops: for all crops
precautions to be taken while biofertilizer application
• store in cool dry and well ventilated place away from direct heat and sunlight.
• do not mix biofertilizers with chemical fertilizers or pesticides.
• keep 15 days interval between application of chemical fertilizers or pesticides.
• use before expiry date.
advantages:
• supply “p” to the plants to the extent of 30 to 50 kg ha.
• saves up to 25-30% of costly chemical fertilizer inputs.
• avoids soil erosion thereby helping in the conservation and
• improvement of soil structure and fertility.
• being environment friendly, it does not disturb ecological balance.
• biophosol can be used for organic farming.
