What are the common ways of manure composting?

Anaerobic composting is a common method of manure composting, which is a composting process mainly using anaerobic microorganisms under anoxic or anaerobic conditions. In addition to humus organic matter, carbon dioxide and methane, the final products also include reducing substances such as ammonia, hydrogen sulfide and other organic acids. The process is simple and does not need ventilation, but the reaction speed is slow and the composting period is long.

Aerobic composting: the process in which microorganisms transform organic matter into stable humus under the conditions of artificial control and certain C/N ratio, humidity, temperature and ventilation. This compost is tasteless and flies-free, but it has a faint earthy smell.

The common composting method (common in China) is static strip composting: it can effectively ensure the inactivation of high temperature and pathogenic bacteria without turning over the pile, and shorten the composting cycle.

Dynamic strip composting: the aerobic state of the pile is ensured by turning the pile regularly manually or mechanically.

Reactor composting: It is carried out in one or several containers, which can effectively control the temperature and humidity, thus monitoring the fermentation degree of compost.
