Manure

Manure is a type of organic matter which is used as fertilizer in agriculture on several different planets across the Milky Way Galaxy. The matter is known to contribute to the fertility of the soil by adding organic matter and nutrients.

One such planet beyond Earth to use manure were the Heiren of the planet Heir'tzan. In 2251, James T. Kirk and Gary Mitchell were forced to jump onto the back of a moving manure truck as they chased a group that had kidnapped a telepath, who was needed for a reconciliation ceremony.
