How to decompose cow dung of farm chickens and ducks?

There are two ways to decompose chickens, ducks and cow dung on the farm: one is to use a decomposing agent, and the other is to use a conventional decomposing method. The former method can be completed in 10-30 days, and the decomposition method can be done according to the instructions. The conventional method is to pile up under aerobic or anaerobic conditions, and generate high temperature through microbial action to decompose organic fertilizer. The specific method is to pile chicken manure into a long pile with a height of 1.5-2 m and a width of 1.5-3 m, add water to about 55%, cover it with plastic film, wait for natural fermentation, and heat it to above 70 degrees to kill some germs. When white hyphae appear in chicken manure, fermentation is completed, and the time is about 3-5 months. When stacking, don't press it too hard, and leave a certain distance between the film and the manure. Such an aerobic environment is conducive to the reproduction of microorganisms and improve the fermentation speed (this is under aerobic conditions). Putting some superphosphate in the pile can improve the utilization rate of phosphate fertilizer and is also good for crop growth.
