Not having been turned over or cultivated, especially in reference to land or soil.
The unplowed field was covered in tall grass and wildflowers.
Unplowed → It is formed from "un-" (meaning not) and "plowed" (from Old English "plōwan", meaning to turn over soil). The word "unplowed" means not turned over or cultivated, referring to land that has not been plowed.
Think of land that is 'not' ('un-') 'turned over' ('plowed') — that's why unplowed means land that hasn't been cultivated.
