Potassium is a major essential plant nutrient that plays a pivotal role in plant physiological
and metabolic processes, and provides resistance against biotic and abiotic stresses. In
order to feed an ever increasing world population, cultivation of high yielding varieties in an
intensive production system during the last few decades caused depletion soil fertility status,
especially potassium (K). As 90–98% K reserves in soil system are non-exchangeable
mineral sources, efficient rhizospheric microbes (ERMs) are needed to effectively dissolve …
