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.

Air Emissions After Manure Land Application Including Subsurface Application of Poultry Litter and Solid Manure

When manure is land applied there are many different gases emitted, including greenhouse gases and those that contribute to odors. How much is emitted and how does that change with different application methods? This presentation was originally broadcast on September 18, 2009.

Evaluating Manure Treatment Through Farm Pilot Project Coordination

Manure treatment technologies are not one size fits all. Wouldn’t it be great if we could learn from others that have implemented many different farm scale technologies? Fortunately, the Farm Pilot Project Coordination, Inc. has a wealth of information related to its 40 projects. This presentation was originally broadcast on August 21, 2009.

Carbon Footprint of Animal Agriculture Webcast

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”

Dust (Particulate Matter) Emissions From Animal Agriculture: An Introduction

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.
