Abstract
The Zinc iron systems were prepared by sol–gel auto combustion methods—varying the synthesis conditions (precursor solutions, chemical compositions, catalysts, temperature and time of aging and heat treatment). The precursors of sol–gel procedures were Zinc nitrate, iron nitrate and glycine was applied as catalysts. The processing features and the micro structural characteristics of ZnFe2O4 phases formed during self-combustion reactions of the gels have been investigated by TG-DTA, XRD and TEM. The oxide has been annulated at 8000C temperature and resulted in ZnFe2O4 nano-particles with crystallites size in the range of 50-60 nm. The prepared Zinc iron systems was treated against the Azotobacter chroccocum by using sole carbon source as a control, the Azotobacter chroccocum important and playing key major role for improving crop productivity, it supply the atmospheric nitrogen by nitrogen fixation process. Azotobacter chroccocum was showing the highest growth response to Zinc iron (ZnFe2O4) ceramics and had excellent bioactivity at low concentration, performing positive correlation but at high concentration of Zinc iron, it decrease their bioactivity, performing negative correlation. Hence the Zinc iron act as best bioactivator for the activity of Azotobacter chroccocum to accelerate the growth.
