Effect of microbial inoculants on composting of chicken manure

Microbial inoculants of Bacillus spp.was added to the mixture of chicken manure and rice stalk.Compared with the control,which was not inoculated,the inoculated compost showed higher temperature,which had 3 more days with composting temperature more than 50℃.The inoculated compost had higher pH value in the earlier phase.At the seventh day,pH value of inoculated compost and the control were 9.23 and 8.87 respectively.However in the later phase,the inoculated compost showed lower pH value.At the end of composting,pH value of the inoculated compost and the control were 8.22 and 8.31 respectively.Both the inoculated compost and the control showed dropping trend of EC and C/N ratio during composting,yet the inoculated compost had significantly lower EC and lower C/N ratio in the later phase.At the end of composting,EC of the inoculated compost and the control were 1.78 and 2.12 mS/cm respectively,C/N ratio of the inoculated compost and the control were 14.2 and 16.9 respectively.
