dc.description.abstract | Increasing availability of phosphate (P) and potassium (K) in the soil
can be driven by microbial activities, which are accurately able to dissolve P
and K, known as nutrients hard to dissolve. The objectives of this research were
to study the solubilizing activity toward soil P and K by P- and K- solubilizing
bacteria in a 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 antibiotic concentration of 50 µg.ml
. The results
of this study shown 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 of 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 solubilizing bacteria,
to be 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
availability in both soils. | en_US |
