An experiment was carried out to observe the effects of a composting promoter and different microorganism composting preparations on fresh cow dung compost,with objectives to study the function of adding materials for accelerating fermentation,through which harmfulness-free national .

The effect of inoculation EM(Effect Microorganism)or non-EM separately on earthworms(Eisenia foetida) disposing fresh cattle manure was studied,with analysis of affecting factors including pH,temperature,available nitrogen,phosphorus and potassium concentration as well as seed germination index and the effects of EM on the growth and reproduction of earthworm.

An incubation experiment of earthworm(Eisenia foetida)disposing fresh cattle manure was conducted to assess the optimal additive concentrations of acetic acid,moisture condition,temperature,inoculation density of Eisenia foetida and concentration of effect microorganism(EM).
