Or just get large pots 18" or so, and grow bags (And the answer is Yes.
you
can grow carrots in pots (just don't choose long rooted varieties).
Then after a year, make hollows on your Gravel/soil and empty pots/grow
bags
in to give you growing media for Shrubs/herbaceous plants .......put in
smaller plants that will develop a root system to suit your ground.
Re fill pots and get more grow bags.
Over time you will build up the soil to something useful.
If you can get good manure etc then top dress the ground with this, let
the
worms take it down for you.

This is very similar to the original square foot gardening theory, as used
in Texas panhandle type country.
Ground that was almost useless was built up, little by little.

As an aside, one of our allotment holders grows his carrots in an old oil
barrel.
Grows them in fine sand with a thin layer of soil on top.
Roots come out nearly three feet long for the annual show.
