unplowed

Unplowed describes land or soil that has not been turned over by a plow in preparation for planting.

A field left unplowed may be fallow, set aside for conservation, or simply neglected.

In winter, unplowed also applies to roads or surfaces not yet cleared of snow: The unplowed streets made the morning commute treacherous.

Figuratively, unplowed can suggest unexplored territory or untapped potential.
