Owners and managers of grasslands need to take several steps to manage unpleasant odors from animal feeding operations, food and ethanol processing plants, or other agricultural activities. Agricultural odors are generated, emitted, and transported from a source to a receptor sites that include property lines, neighbors' houses, and nearby public areas, including public roads, schools, parks, and towns. Odors can be managed by reducing source generation or emission, capturing and treating odorous air, or by increasing dispersion. The odor management is required to reduce odor concentrations to non-offensive levels most of the time at receptor sites. Several states use tools that consider feed-lot size, and production practices for assessing the potential odor impact of animal feeding operations. Chemical and biological additives are used to reduce odor generation or emissions during manure transport, storage, agitation, and land application.
