Research is currently done by a joint team in Quebec and Manitoba to develop a low temperature anaerobic treatment that would control odour emissions and could be easily implemented on farms under our cold conditions. Storages Earthen manure storage sites are used in Saskatchewan to store liquid manure. The size of the earthen manure storage depends on the size of the facility and the storage time required. This type of storage system is relatively inexpensi ve and requires little maintenance. The bacterial action occurring in manure storage can be divided into aerobic and anaerobic, depending on oxygen availability in the manure.
Anaerobic digestion occurs in manure in the absence of oxygen.
Bacteria in the manure digests organic and other matter. This decomposition results in simpler compounds. During anaerobic microbial decomposition many compounds are produc ed. The most notable compounds are carbon dioxide, methane, ammonia and hydrogen sulfide. Under cold conditions, bacterial activity is reduced, and can even stop, so complete anaerobic digestion cannot be obtained under Saskatchewan outdoor storage conditions.
