1. A hybrid turf comprising:
compostable synthetic fibers,
a compostable carrier structure, and
a decomposition inhibitor having a decomposition-inhibiting functionality reducing decomposition of the compostable synthetic fibers and of the compostable carrier structure by reducing the growth and reproduction of microorganisms capable of decaying the compostable synthetic fibers and the compostable carrier structure before expiration of a defined period of time,
wherein the decomposition inhibitor in the turf has a decomposition-inhibiting functionality expiring at or after the defined period of time has elapsed, or
wherein the decomposition inhibitor is configured to leave the turf until the defined period of time has elapsed.
