Producing no crops, to do with farm storage limits (6)
I believe the answer is:
barren
'producing no crops' is the definition.
I can't judge whether this defines the answer.
'to do with farm storage limits' is the wordplay.
'to do with' becomes 're' (regarding).
'farm storage' becomes 'barn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'limits' is an insertion indicator (limit can mean to contain or block off).
're' placed within 'barn' is 'BARREN'.
Can you help me to learn more?
(Other definitions for barren that I've seen before include "Not producing vegetation or offspring" , "Dull" , "Sterile" , "Producing little vegetation" , "Arid, infertile" .)
