Five potassium solubilizing microorganisms were isolated from the arid soil of Jodhpur,
India. Among them two fungal isolates RCKF7 followed by RCKF5 showed higher
dissolution capacity towards feldspar, resulting in the release of more potassium compared
to the others. Based on morphological characters and sequencing of ITS1–5.8S–ITS2
region the strains were identified as Fomitopsis meliae RCKF7 and Aspergillus tubingensis
RCKF5. On further screening of the more potent strain RCKF7, it showed its ability to
grow and solubilize potassium over a wide range of temperature (20 to 38 oC) and pH (5.0
to 10.0). The maximum potassium solubilization index was observed at 28 ºC and pH 6.0.
Capability of RCKF7 to solubilize phosphorus also rendered it an additional advantage.
Furthermore the application of 500 ppm and 1000 ppm feldspar alone or in combination
with RCKF7 resulted in more grain yield in wheat as compared to recommended dose of
potassium fertilizer.
