Increasing cost of the fertilizers with lesser nutrient use efficiency necessitates alternate means to fertilizers. Soil is a storehouse of nutrients and energy for living organisms under the soil-plant-microorganism system. These rhizospheric microorganisms are crucial components of sustainable agricultural ecosystems. They are involved in sustaining soil as well as crop productivity under organic matter decomposition, nutrient transformations, and biological nutrient cycling. The rhizospheric microorganisms regulate the nutrient flow in the soil through assimilating nutrients, producing biomass, and converting organically bound forms of nutrients. Soil microorganisms play a significant role in a number of chemical transformations of soils and thus, influence the availability of macro- and micronutrients. Use of plant growth-promoting microorganisms (PGPMs) helps in increasing yields in addition to conventional plant protection. The most important PGPMs are Azospirillum, Azotobacter, Bacillus subtilis, B. mucilaginosus, B. edaphicus, B. circulans, Paenibacillus spp., Acidithiobacillus ferrooxidans, Pseudomonas, Burkholderia, potassium, phosphorous, zinc-solubilizing microorganisms, or SMART microbes; these are eco-friendly and environmentally safe. The rhizosphere is the important area of soil influenced by plant roots. It is composed of huge microbial populations that are somehow different from the rest of the soil population, generally denominated as the “rhizosphere effect.” The rhizosphere is the small region of soil that is immediately near to the root surface and also affected by root exudates.

In soil system, 90%-98% K reserves are non-exchangeable mineral sources and potassium solubilizing microbes (KSMs) can effectively dissolve this mineral. Nowadays focused research on efficient KSMs was started. These microbes are able to enhanced their root colonization and improve plant growth and development. They solubilize K-minerals through different mechanisms including chelation, acidolysis, lowering of pH, exchange reaction, complexation, biofilm formation and secretion of organic acid and polysaccharides. Bio-priming of seed/root through efficient KSMs resulted higher crop productivity, potassium use efficiency (KUE) and mitigate the K-deficiency in soils. In this article we are trying to summarize the KSMs current state of knowledge in agricultural crops. We highlighted the knowledge gaps and suggest future prospective of research, with hope that the use of KSMs in agricultural soil improved soil sustainability.
