Dairy Farm Odors Like other parts of agriculture, dairy farms have particular odors. Most often, the odor from dairy farms comes from manure. Farmers don t like these odors any more than their neighbors.
Dairy farms collect manure for use on their crop land.
Some farmers collect and spread manure daily or weekly. Other farmers store the manure for several months, empty their manure storage only a few times a year. During spreading periods the smell can be very strong. Many factors determine the range and strength of farm odors. Many of these a farmer has no control over.
