Rock Phosphate (RP) is any naturally occurring geological material that contains one or more phosphate minerals suitable for commercial use. There is a major RP deposit in Eppawala, Sri Lanka and this RP identify as Eppawala Rock Phosphate (ERP). Large proportion of soluble inorganic phosphate added to soil is rapidly fixed as insoluble forms soon after application. Development of an economical and environmentally friendly alternative for successful soil P management is major concern in crop production and Phosphate Solubilizing Microorganism (PSM) attracted attention in this regard. This study was conducted to identify the Phosphorus solubilizing bacteria. Soil samples were collected from different Agricultural crop lands. Soil were Spread cultured in NBRIP medium after a serial dilution. The bacterial colonies that produced clear zone of activity were considered as potential phospha.. View More»
