Suitable for crops (6)
I believe the answer is:
arable
'suitable for crops' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for arable that I've seen before include "Suitable for ploughing" , "Suitable to grow crops" , "Of land, capable of growing crops" , "Fit for crop growing" , "Land used for crops" .)
