Popis:	Increasing availability of phosphate (P) and potassium (K) in soil can be driven by microbial activities, which are specifically able to dissolve P and K, known as nutrients hard to dissolve. The objectives of this research were to study the solubilising activity toward soil P and K by P- and K- solubilizing bacteria in sterilized and non-sterilized condition of Oxisol and Inceptisol. Marking procedure was performed on P- and K- solubilizing bacteria to scrutinize their activities in the soil. Marking process was conducted by utilizing resistance toward rifampicin antibiotica concentration of 50 µg.ml−1. The results of this study revealed that the increasing availability of P was evident in both soil conditions (sterilized and non-sterilized). In Oxisol, P availability increased by 48.86%, while in Inceptisol it reached an increase by 187.77%, compared to the initial concentration. Likewise, K availability in Oxisol increased by 4.53 times, and it rose by 5.26 times in Inceptisol. The activities of P solubilising bacteria, in addition to being able to increase soil P availability, were also able to enhance soil’s K content. Similarly, the K solubilizing bacteria were also capable of increasing P availabilityy in both soils.
