September grains : not traded?

It seems like everyone is switching to the december contract instead of september on wheat and corn.

Is there some fundamental reasons related to crops... ? Is it always the case that september contract as no interest?

Thanks.
 
September is a "swing" month between the old-crop and new-crop. Commercial users build-up bigger positions in the "harvest month" because that's where the big supply will be later on.
