PSB (Phosphate Solubilizing Bacteria)
CFU of the Product:
3X 10^8 per ml for liquid formulation.
1X 10^8 per gram for carrier formulation.
Mode of action:
PSB Bio Fertilizer Due to immobilization of phosphate by mineral ions such as Fe, Al and Ca and organic acids, the rate of available phosphate in soil is well below plant needs. Chemical fertilizers are also immobilized in the soil, immediately so that only 20% of added fertilizer is absorbed by plants.
PSB Bio Fertilizer converting insoluble phosphatic compounds such as rock phosphate, bone meal and basic slag particularly the chemically fixed soil phosphorus into available form.
Bio Fertilizer PSB Such organism not only assimilates phosphorus but also cause a large amount of soluble phosphate to be released in excess of their own requirements and saves P2O5 up to 30 – 50 Kg/ ha.
Bio Fertilizer PSB activity is determined by the ability of microbes to release metabolites such as organic acid (lactic acid, malic acid, gluconic acid, fumaric acid, succinic and acetic acid).
PSB Bio Fertilizer Inorganic phosphorus is solubilized by action of organic (gluconic, ketogluconic) and inorganic acids (Hcl) secreted by PSB Bio Fertilizer and maintain the soil pH. The pH of rhizosphere is lowered the bio-carbonates release (anions/cation balance) and oxygen/carbon oxide gaseous exchange. Phosphorus solubilizing ability of PSB Bio Fertilizer has direct correlation with pH of the medium.
Benefits to the crop:
- PSB Bio Fertilizer Increase micronutrients availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P2O5.
- Bio Fertilizer PSB Encourage faster root growth for water and nutrient uptake.
- PSB Bio Fertilizer produce organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P2O5 up take, maturity and increase yield.
- Bio Fertilizer PSB Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.
- PSB Bio Fertilizer Compatible to other beneficial microbes with the plant like growth promoting substance.
- Bio Fertilizer PSB Reduce 25 – 30% phosphatic fertilizer requirement.
Target crops:
Method of application and dosage:
- Seed Treatment – Mix 4 – 5 ml PSB Bio Fertilizer in 50 – 100 ml of water, mix thoroughly with the seed and shade drying for 1 hour before sowing the treated seed.
- Seedlings Treatment– Mix 4 – 5 ml PSB Bio Fertilizer per lit. of water. A solution of PSB Bio Fertilizer is prepared; seedlings are dipped in this solution for about 30 minutes before transplanting.
- Soil Application – Mix 500ml – 1.0 lit/acre of Bio Fertilizer PSB in 40-50 kg of well decomposed F.Y.M/compost or vermicompost or field soil and broadcast in the field before sowing or broadcast up to 45 days after sowing in standing crop and irrigate the field.
- Drip irrigation – Mix Premium Bio Fertilizer PSB 500 ml – 1.0 lit /Acre in 100 liter of water and irrigate the field through drip irrigation.
Compatibility:
- Friendly with bio-fertilizers and bio-pesticides.
- Don’t mix with chemical Bactericide (antibiotic).
