For isolation and detection of potassium solubilizing bacteria from soil sample. Soil potassium supplementation relies heavily on the use of chemical fertilizer, which has a considerable negative impact on the environment. Potassium-solubilizing bacteria (KSB) could serve as inoculants. They convert insoluble potassium in the soil into a form that plants can access. This is a promising strategy for the improvement of plant absorption of potassium and so reducing the use of chemical fertilizer. A wide range of bacteria namely Pseudomonas, Burkholeria, Acidothiobacillus ferrooxidans, Bacillus mucilaginosus, Baciluus edaphicus, B.circulans and Paenibacillus sp. have capacity to solubilize K minerals. Potassium solubilizing bacteria have been reported to exert beneficial exert beneficial effects on growth of cotton, pepper and cucumber, sorghum, wheat and Sudan grass. Therefore, potassium solubilizing bacteria are extensively used as biofertilizers. Alekshandrow Agar is widely used for isolation and detection of potassium solubilizing bacteria from soil samples. Salts present in medium provide essential nutrients to support the growth of potassium solubilizing bacteria. The source of potassium salt is potassium alumino silicates. Potassium solubilizing bacteria forms clear zone around the colony due to potassium solubilization in the vicinity of the colony.
