This study investigates the biosynthesis of iron oxide nanoparticles (FeONPs) using the cell-free supernatant of Pseudomonas fluorescens. The synthesized FeONPs were characterized through UV-VIS, XRD, FTIR, FESEM, EDX, TEM, BET, and VSM analyses. The XRD results confirmed that FeONPs were successfully synthesized and EDX analysis indicated that iron accounted for 89.

- The study explores a method to enhance the release of non-exchangeable potassium (K) from mineral sources like feldspar and phlogopite as a sustainable alternative to chemical fertilizers.
- Two experimental designs were employed: the Plackett-Burman design to assess the effect of different carbon sources, and the central composite design to analyze variables like pH, carbon concentration, and incubation time on K release.
- Findings revealed that optimal conditions for K release included high pH levels (around 10.36-10.31), specific sucrose concentrations, and certain incubation times, with the predictive models explaining up to 92.6% of the variations in K solubility.
