Abstract
Large confined dairy cow feeding operations have increased recently in the Pacific Northwest. They produce huge quantities of manure, odors from which can bring conflicts with neighbors. This 23-page publication details a number of options for reducing odors and resulting conflicts.<b>Please note one correction:<b> On page 9, where it reads, "and a blend of material that meets a desired ratio of carbon to nitrogen, ideally between 20:1 and 30:1 (optimal C:N ratio is 25)" should now read as follows: "... ideally between 20:1 and 40:1) (optimal ratio is 30:1)."
