Odour Cologne It Sure Ain't
Some college students have earned extra cash to sniff livestock excrement. Students at Purdue University in Indiana can earn $30 per session to inhale and then rate whiffs of air collected from barns filled with hogs, cows and chickens. It's a science experiment conducted by a professor of agricultural and biological engineering. He's searching for ways to improve methods for estimating the distance that livestock farm's odour emissions can travel.
