Food security is a burning problem before scientists, which mainly concern with the scarcity and accessible food for all. Scientists are ever-involved to find-out the solutions to overcome on these hurdles, majorly by boosting soil Fertility. Over the last 20 to 30 years, the role of soil microbiome in the improvement of soil fertility and crop productivity by involving role of the microbial life has been emerged sustain and facilitated soil nutrients availability to the plants. The microbial life as the great engines enriching soil and helping to facilitate the breakdown of organic matter, that can be recycled into new life, if only they could be unlocked from that organic matter and also, from the mineral matter. The microbes, especially endospore forming Bacilli are incredibly important in the rhizosphere. Bacillus is a versatile candidate providing its services in plant growth and health promotion tirelessly. This aerobic microorganism is powered with super abilities to produce endospore resting fruiting bodies, whenever it feels unhappy under adversity. Bacillus is also known for its several characteristics, to help crop plants by virtue of producing metabolites similar to plant in the form of phytohormones. Besides, it is able to mineralize rocks and minerals into bio-available form and can metabolize organic matter into much simpler forms. Plant pumps huge amount of sugar and other organic matter in the soil through roots, which attract bacteria to fasten their growth on spent of these supplements. In addition, Bacillus is known to produce sort of secretions of which assist in root colonization due to rhizo-competence on root surface and sometimes invade in root cells. In this chapter, we have reviewed the benefits of Bacillus species to the food security crops in term of raising productivity and yield.
