Abstract

One of the macronutrient which is highly needed for plant growth, uptake and development is Phosphorus, apart from Nitrogen and Pottasium. Comparison to other elements it is the least mobile element in plant as well as in soil and so its needed that the Phosphorus present in the soil in the anonymous form should reach to the plants in the soluble and usable form. Phosphorous solubilizing organisms play key role in phosphorous nutrition by enhancing and increasing its avalibilty to the plants through the release from various niches by solubilisation and mineralization. Soils from various parts of garden were taken and a laboratory study was carried out for isolation and identification of Phosphorus solubilizing Microorganisms (PSM). PSM isolated from various soil samples indicated the mechanism behind the Phosphorous solubilisation is pH reduction by production of various organic acids. The efficacy of PSM to solubilize phosphorous enhances transpiration, photosynthesis, respiration, flower formation, fruit production. The present study indicates that the presence of diverse plants in the garden associated with Phosphorus solubilizing micro organisms act as potential and efficient bio fertilizers which can be a new tred in present scenario.
