I never knew there was such a thing. Never knew govt (and other) scientists spend a lot of time and energy working on ways to make pig, cow and chicken poop smell good either, but here is just a short excerpt:

PEORIA, Ill.— Terry Whitehead's lab here is stocked with glass boiling flasks, Bunsen burners—and cans of extra-strength air freshener.
The microbiologist for the U.S. Department of Agriculture works with pig manure in a quest for something that has largely eluded scientists and entrepreneurs: an affordable way to clear the air in farm country.
In a region where hogs can outnumber people, Mr. Whitehead's research is the ultimate icebreaker.
"First, you say, 'I work with manure,' and they say, 'What?' Then you say, 'Odor,' and they say, 'Thank God,' " says the lanky 57-year-old, who recently attended the North American Manure Expo in Missouri. ("It would be a real waste" to miss it, the event website says.)
Efforts to combat the acrid odor of swine manure, which typically is stored in giant pits, have increased as farms get bigger and suburbs creep closer. The smell can pit neighbor against neighbor, sparking complaints and court battles, not to mention environmental concerns.
