Earning cash for smelling livestock manure
Purdue University students are doing just that, earning US$30 per session for
smelling odours collected from livestock barns as part of an odour research
The students have to place their noses inside an olfactometer and smell
diluted samples of air taken from different locations on farms.
The project is being conducted by Albert Heber, a professor of agriculture
and biological engineering at Purdue. The purpose of the project is to improve
the methods for determining a given livestock farming operation's odour
