Not prepared to grow crops (12)

I believe the answer is:

uncultivated

I'm a little stuck... Click here to teach me more about this clue!

'grow crops' is the definition.
I can't tell whether this definition defines the answer.

'not prepared' is the wordplay.
'not' becomes 'un' (prefix meaning 'not').
'prepared' becomes 'cultivated' (cultivating is a kind of preparing).
'un'+'cultivated'='UNCULTIVATED'

'to' acts as a link.

Can you help me to learn more?

(Another definition for uncultivated that I've seen is " Not highly educated".)

I've seen this clue in The Globe and Mail.
