  • Abstract:
  • For plants to flourish, potassium is a necessary nutrient, and it is crucial for agricultural production. It is needed in large amounts and has two main functions as it activates enzymes that are vital to metabolic activities and required mainly for the production of proteins and starch. Plants can only use 1-2 percent of the potassium that is found naturally in soil or that is provided by synthetic fertilizer; the remainder is bound with other minerals and is therefore inaccessible to plants. One of the most significant microorganisms in saline soil that influences soil health is bacteria. Effective soil microbes that mobilize potassium have a significant impact on soil fertility, potassium ion cycling, and mineral availability. Meteoric impact crater Lonar Lake located Maharashtra is known for its great treasure of alkaline extremophilic bacteria. The present study is carried out to study the potassium solubilizing traits of bacterial isolates from Lonar Lake. Eight bacterial isolates are screened. Out of which the RSML S2 isolate exhibited maximum potassium solubilisation ability at varying pH and salinity conditions. The isolate may be exploited for development of biofertilizer after exploring its other plant growth promoting traits.
