ABSTRACT
Potassium (K) is essential to plant growth and development. It is involved in the adjustment of plant cellular osmotic pressure and the transportation of compounds in plants. It promotes the activation of enzymes, the utilization of nitrogen and the syntheses of sugars and protein. It also boosts plant photosynthesis. In plants, K deficiency causes yellowing of the leaf edges, giving them a burned appearance. It can also cause slow growth and incomplete root development. Soil potassium supplementation relies heavily on the use of chemical fertilizer, which has a considerable negative impact on the environment. Plants can only take in K through the soil. Injudicious application of chemical fertilizers in India has a considerable negative impact on economy and environmental sustainability. There is a growing need to turn back to nature or sustainable agents that promote evergreen agriculture. Among such natural bio-agents, the potassium solubilizing microorganisms, which solubilize fixed forms of potassium to plant available K by various mechanisms including acidolysis, chelation, exchange reactions, complexlysis, and production of organic acids, are considered one such available alternative. KSM represent an enormous potential to transform the problems associated with the agrarian sector. Potassium solubilizing microorganisms play vital role in making potassium available to plants .they solubilize potassium from insoluble forms like fieldspar, mica by producing organic acids and various enzymes. The article includes the work done on various potassium solubilizing microorganisms, mechanism of K solubilization and its use.
Key words: Potassium, Solubilization, Micro-Organism, Diversity, Mechanism.
