Will a compost pile produce objectionable odors?

Question:

Will a compost pile produce objectionable odors?

Answer:

A properly prepared and maintained compost pile will generate little, if any, objectionable odors.  Unpleasant odors may arise if the compost pile contains excessive amounts of wet plant materials (such as fruit or grass clippings), is kept too wet, or is not turned on a regular basis.  When constructing the compost pile, mix wet plant materials with dry plant debris.  Keep the compost pile moist, but not wet.  The composting material should feel damp like a wrung-out sponge.  Turn the compost pile at least once or twice a month.  Odors are emitted by poorly prepared or maintained compost piles.
