Not producing crops, or lacking crops; describing land that is barren or not used for agriculture.
From 'crop' plus the suffix '-less' (meaning without), following the standard English pattern of creating opposites by adding '-less' to nouns.
The '-less' suffix is the opposite of '-ful,' and English uses both constantly—notice how we can say something is 'hopeful' or 'hopeless,' showing how the language gives us infinite ways to express negation and absence.
