Silicate bacteria were identified for fertility management and in this review as biological control in soil.The main source of silica in soil are the silicate minerals. However, monosilicic acid is the only soluble form of silicon for plant absorbation. This acid (monosilicic acid) can be produced by several ways such as rock-weathering mostly of these ways depends on microbial activities namely silicate solubilizing bacteria (SSB). The present work discussed  silicate solubilizing bacteria as a very important factor in this scale and commonly used in plant diseases. The very important role of silicate bacteria is converting insoluble forms of silicates minerals to soluble ones. Furthermore, silicate bacteria can also solubilize other beneficial element for plant such as potassium. Potassium element enhances plant defense mechanisms against phytopathogens and hence increase soil fertility to develope growth of plants. Silicate bacteria enhance resistance against several soil borne fungi with supplementation of silicon which inhibits many plant-pathogen systems and protects plants against pathogens. By producing  bacterial metabolites such as organic acids and the antagonistic activity of this bacteria against the pathogens the silicate bacteria can protect the plants. Thus, the silicate-mediated can affect bioavailability of silicon by decreasing doses of pesticide use, sustainable agriculture  and developed health of plant.
