The current scenario of potassium (K) depletion in soil is slowly increasing due to K fixation or the unavailable form of K in soil. Presently, farmers are faced with a problem of higher price of K fertilizer or other fertilizers in market so farmers are unable to fulfill the demand of potassium in soil for plant growth. Potassium deficiency affects the nutritional quality, mechanical stability, and also pathogen resistance of crops. Therefore, that times needs to fallow the sustainable technology for sustainable agricultural production through use of microbial consortia of potassium-solubilizing microbes or biofertilizer/PGPR under organic farming system. The potassium-solubilizing microorganism is one of the best sustainable technologies, which solubilizes the fixed form of K available for plant uptake. Thus, the bio-formula of the potassium-solubilizing microorganism as biofertilizer offers environmentally sustainable …
