Abstract: One strain of B. Mucilaginosus was inoculated into sandy soil and the media containing different silicate minerals. It was found that phosphorus, potassium and silicon content increased significantly in the sandy soil. Potassium was released at different rates from 5 different silicate minerals and became extractable. A small amount of the potassium released from the minerals was absorbed by bacterium. Fumigation could make the K inside the cell extractable to water.

Key words: B.Mucilaginosus, P dissolution, K dissolution
