Fighting Manure

Farmers seeking ways to control smell of manure

Some Pennsylvania farmers are looking for ways to curb the stench of manure before rules could force them to. Governor Ed Rendell's administration says it'll push for odor restrictions on certain new or expanding farms. Iowa is one of a few states that already have such rules. The stench issue has gained momentum with more city-dwellers moving closer to farms. Some neighbors say the smell lowers real-estate values and makes them physically ill.

Farmers are seeking the help of scientists and entrepreneurs to squash wafting odors. But a Penn State professor warns "There's a lot of snake oil out there."

Some in the agricultural industry caution against imposing too many restrictions. A feed mill worker says if people want food production, they have to put up with "certain kinds of inconveniences."
