description
Proceedings available at: http://www.extension.org/67597 Smell is perhaps the least understood of our five senses. Yet, the human perception of odor may mean the difference between war and peace for a livestock farmer and his neighbors. Because the science of smells is complex, there is a tendency to run straight for the organic chemistry book when we try to describe farmstead odors. This approach goes right over the heads of most people. There must be a better way to communicate odors to diverse audiences. Come to this workshop and find out how.
