Abstract: Effect on dairy manure treatment by static bed composting, outdoor windrow composting and microbe reagent inoculation had been studied. Comparing with the outdoor windrow composting, the bed composting system is more efficacious to make compost shape, can save more than 50% land, and avoid the second pollution. The outdoor composting pile’s temperature reached 50℃ advanced 3 days contrasted with bed composting. The pile temperature of inoculating microbe reagent raise over 50℃ was 2～3days faster than the pile without inoculation; the germination index showed the dairy manure were harmless to plant after 20 days composting in these experiment.
