Connecting agri-professionals advancing environmental stewardship in animal agriculture.
Many people are concerned about greenhouse gases and climate change. The carbon footprint of animal agriculture is an issue being used by many to encourage people to eat less meat. What is the true footprint of US animal production? How does production efficiency impact the numbers? This presentation was originally broadcast on July 31, 2009. More… Continue reading “Carbon Footprint of Animal Agriculture Webcast”
What is the current state of the science on measuring greenhouse gas emissions from animal housing and manure storage areas? This presentation was originally broadcast on May 15, 2009. More… Continue reading “Greenhouse Gas Emissions Research on Animal Agriculture”
Air emissions from animal animal feedlots are sources of many different emissions including particulate matter (dust).
The materials on this page were developed to assist educators and professors who wish to include dust and particulate emissions and their control as a topic in their classrooms or educational programs.

How do researchers measure air emissions from open lots? What are they learning about ammonia, hydrogen sulfide, and particulate matter (dust) emissions? This presentation was originally broadcast on March 27, 2009. Continue reading “Air Emissions From Cattle Feedyards and Dairies”
What strategies are effective in reducing air emission from animals? Learn more about research into beef, dairy and swine. This presentation was originally broadcast on January 16, 2009. More… Continue reading “Feeding Strategies To Reduce Animal Air Emissions Webcast”
Hydrogen sulfide gas (H2S) is produced from animal manures under anaerobic conditions. Hydrogen sulfide is an odorant and is known as an indoor air pollutant where it can reach toxic, and even lethal, concentrations. But is it more than just an odorant at normal outdoor concentrations? This presentation was originally broadcast on September 19, 2008. More… Continue reading “Hydrogen Sulfide, How Serious an Outdoor Air Quality Concern”
This webcast focuses on an introduction to the National Air Emissions Monitoring Study (NAEMS). This program was originally broadcast on July 18, 2008. More… Continue reading “Introduction to the National Air Emissions Monitoring Study (NAEMS)”
Ammonia is rapidly becoming an issue of great importance to animal agriculture. Find out why it is a concern and learn more about the effectiveness of best management practices for reducing ammonia losses to the atmosphere.
