Mode of action

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 converting insoluble phosphatic compounds such as rock phosphate, bone meal and basic slag particularly the chemically fixed soil phosphorus into available form. 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. Phosphorus solubilizing 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). Inorganic phosphorus is solublizedby action of organic (gluconic, ketogluconic) and inorganic acids (Hcl) secreted by PSB and maintain the soil pH. The pH of rhizospheree is lowered the bio-carbonates release (anions/cation balance) and oxygen/carbon oxide gaseous exchange. Phosphorus solubilizing ability of PSB has direct correlation with pH of the medium.

Target crops:

Cereals (Wheat, Paddy, Maize, Barley),Pulses(Soybean, Green gram, Chickpea, Black gram, Pigeon pea Pea), Oil seeds (Sunflower, Ground Nut, Mustard, Coconut, Safflower), Fibrous(Cotton, Jute), Vegetables, Fruit and Plantation crops

Benefits to the crop:

• Increase micronutrients availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P2O5.
• Encourage faster root growth for water and nutrient uptake.
• PSB produce organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P2O5 up take, maturity and increase yield.
• Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.
• Compatible to other beneficial microbes with the plant like growth promoting substance.
• Reduce 25 – 30% phosphatic fertilizer requirement.

Method of application

• Seed Treatment – Apply 10 ml Premium Phosphofix in 1.0 kg of seeds and add sufficient quantity of water. Mix the entire seed with prepared mixture for coating the seeds, dry under shade and sow the seed early morning or late evening.

• Soil Treatment – Apply 500ml – 1 lit. /acre Premium Phosphofix in 50kg well decomposed Fym/compost/vermi compost/field soil thoroughly and broadcast in the field before sowing/planting or in the standing crop.

• Seedlings Treatment – Mix 100 ml Premium Phosphofix in 10 lit. of water and dip the seedlings root for 20 – 30 minutes before transplant the seedling.

Method of application and dosage

• Soil Treatment – Apply 4 kg/acre Premium Phoster in 50kg well decomposed Fym/compost/vermi compost/field soil thoroughly and broadcast in the field before sowing/planting or in the standing crop.

Incompatibility

• Avoid treating the seed with Antibiotics.
