Manure and Litter Additives for Odor Control on Farms

Air emissions from animal agriculture operations and their associated manure storage are being examined more closely as a way to mitigate potentially harmful gases and odors. Manure additives and litter amendments go right to the source and are used to change one or more characteristics of manure to try and reduce emissions emissions of odorous gases. The materials on this page were developed to assist educators and professors who include manure additives or litter amendments as a topic in their classrooms or educational programs.

Wet Scrubbers for Cleaning Air Emissions from Animal Housing Curriculum Materials

Air emissions from animal housing systems are being examined more closely for ways to mitigate potentially harmful gases. Wet scrubbers are one way to remove pollutants from air being exhausted from mechanically ventilated buildings.  The materials on this page were developed to assist educators and professors who include wet scrubbers as a topic in their classrooms or educational programs.

Manure Storage Covers Curriculum Materials

Air emissions from animal agriculture operations and their associated manure storage are being examined more closely as a way to mitigate potentially harmful gases. Covers are becoming popular as a way to collect methane (a potent greenhouse gas) for beneficial reuse as a renewable energy source.  The materials on this page were developed to assist educators and professors who include manure storage covers as a topic in their classrooms or educational programs.

Odors from Livestock Farms Curriculum Materials

One of the easiest air emissions to recognize from livestock and poultry farms is odor. It is also the most complex to characterize and study. Odors are a combination of hundreds of different emissions. Each person who smells odor interprets it differently than another person as well. With all of these variables, how can we communicate the issue of odor to students and ag professionals? These materials were developed for instructors to use in classrooms or extension programs.

Laboratory Exercise on Odor and Smell

From Dr. Doug Hamilton, Oklahoma State University

Slides and recording of author presenting the workshop. A 2 hour laboratory/workshop exercise has been presented to over 250 college freshmen.

Video: Odors on Livestock and Poultry Farms

What role does odor play today for livestock and poultry producers? Are there ways to effectively manage odors from livestock and poultry operations and still keep the industry viable? This video examines some of the odor issues that exist in rural communities and shows examples from Nebraska of how research information is being put to use on farms.

Ammonia Deposition in Rocky Mountain National Park: What Is the Role of Animal Agriculture?

Air quality concerns related to animal agriculture include ammonia. One area that this has become apparent is Rocky Mountain National Park in Colorado. The park appears majestic and pristine. But is everything really in harmony?

Ammonia Deposition Alpine Ecosystems


Ammonia, which is a basic atmospheric gas emitted from livestock and other farms, combines with nitrogen oxides from cars and other combustion sources to create nitrogen particles which deposit in the park. As a result, this fragile ecosystem is being changed. What part do livestock operations play and how can they help preserve this national treasure?

Odor Measurement in Animal Agriculture

Odors are the most common nuisance complaint associated with animal feeding operations (AFOs), but is one of the most challenging to measure. Unlike other air emissions from AFOs odor is not one easily identifiable gas or molecular compound. Instead, odor is made up of many (hundreds!) of individual odorous compounds. Complicating this scenario is the fact that each person on the receiving end of odor has a different perspective, different tolerance, and different interpretation of what they are smelling. The following materials were developed for college instructors to utilize in their classrooms when presenting about odors.
