Description

Soil potassium supplementation relies heavily on the use of chemical fertilizer, which has a considerable negative impact on the environment. Potassium-solubilizing bacteria convert insoluble potassium in the soil into a form that plants can access. A wide range of bacteria namely Pseudomonas, Burkholderia, Acidothiobacillus ferrooxidans, Bacillus mucilaginosus, Bacillus edaphicus, B.circulans and Paenibacillus sp. has been reported to release potassium in accessible form from potassium bearing minerals in soils. Potassium-solubilizing bacteria have been reported to exert beneficial effects on growth of cotton, pepper and cucumber, sorghum, wheat and Sudan grass. Therefore, potassium solubilizing bacteria are extensively used as biofertilizers.
