Re: Vented Crawl Space Cellulouse Insulation
I would have to say ..... No ...... to placing the insulation directly on top of the dirt without a vapor barrier.

If the insulation is merely sitting on top of the dirt without a vapor barrier the moisture from the ground will wick up into the insulation which is not a good thing.
besides .... for the last couple of years that area has been dry .... what if next year things change? You may suddenly have water entering that crawl space which will leave you a soggy mess of insulation that will need to be removed and likely discarded.
Also ..... the insulation should be filling the cavities between the floor joists right to the underside of the subfloor and it's unclear if that 18 inches is from the underside of the floor to the dirt or from the joists to the dirt.
Just a thought.
