Variation of Compost's Qualitative and Quantitative Indices in Vermicomposting Process

Nowadays, public undrstanding on vermicompost process has increased and its deployment to convert organic waste into vermicompost has been increasingly expanded.Widely application of vermicompost requiers high level of knowledge on its process as well as the its effect on major indicators of quality control and organic fertilizer volume obtained from the raw waste.In this study the effect of vermicompost process, in which earth worm activity has substantial effect, on the indices such as the amount of carbon and nitrogen, C/N ratio, pH and volume of waste during the vermicompost production process was investigated.

In this study food waste used as raw material for vermicompost. After initialpreparation, food wastes were composted using Eisenia foetida species for one month and the above mentioned indicators were monitored.

final pH and C/N ratio after 1 month vermicomposting process were 7.53 and 20.82,respectively. There was 56% reduction in waste volume in preparation stage and 11.75% in vermicompost process. Conclusio: appropriately and that the final product can be used as fertilizer. In some cases factors like pH reaches to standard value of an A class compost during 1 month processing.
