Nitrogen fixing bacteria,Azotobacter chroococcum, and phosphate solubilizing fungi,Aspergillus awamori, caused marked decrease in C:N ratio and increase in P concentration of vermicompost prepared from farm wastes and cattle dung withEisenia foetida.Inoculated microbial count was maximum (29.7 × 106g−1of vermicompostA. chroococcum; 18.7 × 103g−1of vermicompostA. awamori)on day 45. Similarly, the enzymes dehydrogenase and alkaline phosphatase showed maximum activity of 867.7 μg TPF g−1vermicompost h−1and 327.5 μg of p-nitrophenol released g−1vermicompost h−1, respectively, on day 45 and then declined on day 90. The phytohormone indole acetic acid was also detected in vermicompost, produced by microorganisms. Increase in P concentration and decrease in C:N ratio was higher in microbial and worm inoculated treatments than in the control, which indicates maturation of vermicompost.
