Anneo-P Phosphate Solublizing Bacteria Powder

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. Phosphate Solubilizing Bacteria (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 P O up to 2 5 30 – 50 Kg/ha. Phosphorus solubilizing activity is determined by the ability of microbes to release metabolites such as organic acids like (lactic, malic, gluconic, fumaric, succinic and acetic acid). Inorganic phosphorus is solublized by the action of organic (gluconic, keto-gluconic) and inorganic acids (Hcl) secreted by PSB 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 has direct correlation with pH of the medium.

Target crops:

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

Benefits to the crop:

• Increases micronutrients availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P O . 2 5

• Encourage faster root growth for water and nutrientuptake.

• PSB produce organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P O up take, maturity and increase yield. 2 5

• Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.

• Compatible to other beneficial microbes.

• Reduce 25 – 30% phosphatic fertilizer requirement.
