When you look at air pollutants like NOx, NH3, NMVOC, etc. excreta deposited by grazing livestock has a lower emission factor than those deposited in yards/housing, where corn-fed cattle are usually kept. [0] > The more time grazing livestock are housed, the smaller the proportion of their excreta deposited on grazed pastures will be, and hence the smaller the emissions from those pastures.
