Yes they cancel each other out.

To use the boosts most effectively, put like elements on the same island, and put their opposites on the same island (i.e. put plant and fire w/ boosts on the same island and metal and cold w/boosts on another island). That way you do not cancel out your monetary benefits for any of your dragons.
