Définition de 4B Manure Management Catégorie de sources
Methane and nitrous oxide are produced from the decomposition of manure under low oxygen or anaerobic conditions. These conditions often occur when large numbers of animals are managed in a confined area (e.g. dairy farms, beef feedlots, and swine and poultry farms), where manure is typically stored in large piles or disposed of in lagoons and other types of manure management systems. Methane emissions are covered in Sections 4 B 1 to 4 B 9 and N2O emissions in Sections 4 B 10 to 4 B 12 below.
