For the most part, methane emissions from animal husbandry are endogenous. In contrast, nitrous oxide is mainly produced during the storage and processing of animal excrements and after their application. The literature study indicates that at this time only a low and very restrictively usable amount of exact data about methane and nitrous oxide emissions from animal husbandry exists. For cattle keeping most of the data. 收起
