Phosphate solubilizing microbes: an incredible role for plant supplements

Abstract

Plants procure phosphorus from soil as the phosphate anion. It is the most un-portable component in plant and soil in comparison to other macronutrients. It’s very well known that phosphorus is the second most significant supplement after the nitrogen required/needed in plant growth. It is a fundamental component in every single living system. Barely 1%-2% of phosphorous is provided to different parts of the plants. It precipitates in soil as orthophosphate or is adsorbed by Fe and Al oxides through legend exchange. Phosphorus-solubilizing bacteria play a substantial part in phosphorus nutrition by increasing phosphorus' accessibility to plants through discharge from inorganic and natural soil P pools by solubilization and mineralization. Lowering the pH of the soil through microbial generation of natural acids and mineralization of natural phosphorus by acid phosphates is the key element in the soil for mineral phosphate solubilization. Chemical composts are used as an additional source of phosphorous to satisfy the plant’s need. Additionally, co-inoculating P solubilizing microorganisms with other beneficial bacteria and mycorrhiza has shown to increase their efficiency. Microbial inoculants or biofertilizers can thus be used as an alternative source because they are both economical and environmentally favourable.
