    Abstract

    Globally the agricultural activities are having shrinkage in terms of area and salinization of agricultural lands is one of the most serious environmental problems. Nationally our land is affected by salinity and alkalinity, and thus results in decreased production. Phosphorus being one of the essential mineral nutrients limits the plant growth and is unavailable to plants due to its low solubility and high fixation in the soil. Hence, this is rectified with additional supply of as phosphatic fertilizers. However, major portion of soluble inorganic phosphate in form of chemical fertilizer applied to soil is immobilized rapidly and occurs in oxidised form as phosphates bounded to aluminium, calcium or iron and becomes unavailable to plants. Hence, the use of phosphorus-mobilizing bacteria can provide a solution to the problem of limited phosphorus availability in salt-affected soils. The application of phosphorus-mobilizing bacteria as biofertilizer can not only improves the growth and quality of produce, but also drastically reduces the usage of chemical fertilizers. Hence, phosphorus-mobilizing bacteria can be used as environment friendly bio-fertilizers help to reduce the requirement of phosphatic fertilizers
