Effect of Inoculating Microbes on Composting Process of Cattle Manure

A compost test was conducted to study effects of inoculating microbes and matured compost on cattle manure composting.The results indicated that inoculation of microbes and matured compost significantly increased rising rate of temperature during earlier stage of composting process,which reached at high thermophilic phase(50 ℃)earlier 1~4 days than the control.It has been also found that the more microbes were added,the faster the temperature rose.Especially,the duration of the composting temperature above 50 ℃ with inoculating microbes at 600 mg·kg-1 and matured compost at 50 g·kg-1 was 3~4 days longer than the control.The compost with inoculating microbes at 600 mg·kg-1 and matured compost at 50 g·kg-1 achieved maturity after 29 days,and their seed germination index(GI) reached 92.1% and 84.4%,respectively.However,other treatments did not achieve maturity after 29 days.Therefore,addition of adequate amount of microbes and matured compost could speed maturity of the compost and shorten the composting period.
