Abstract

Soil an important natural wealth comprises of microbes and minerals that construct the nutrient source and sink for biological uptake. Interactions between soil microbes and minerals play a major role in nutrient cycling processes and convert to available forms through solubilization, mineralization and mobilize nutrients from soil components. Biological source for potassium is very minimum compared to nitrogen fixation and phosphorus solubilization. An experiment was conducted to formulate a new medium for an efficient potassium releasing bacterial isolates (KRB). The growth rate, optical density, enumeration was analyzed and compared. Using the best carbon and nitrogen source a new medium was designed for mass production process. Sucrose and dextrose were the best carbon source and yeast extract and peptone were the two best nitrogen sources. For maximizing the population, new medium was formulated and compared with the two existing medium, Alexandrovs’ and Sucrose minimal agar med
