Odor can be minimized with various management techniques. Minimizing the manure storage surface area, covering manure storage facilities, reducing dust and feed wastage inside buildings, increasing air exchange, filtering odorous air, modifying diets, utilizing pit additives and incorporating manure during land application all help minimize odours.
Over 60% of Iowa producers utilize a “100% containment of manure” system, which greatly reduce odours by storing manure below the buildings in concrete structures. Some final methods of reducing odours include limiting agitation time, limiting the pump outs per year, applying a manure management plan, reducing water and feed losses.
