Yes you can manufacture sand and/or rock dust. You can plant whatever
you like in your dusty plot. Without organic matter to hold moisture -
and without moisture, for that matter - your plants won't survive.

You think to grow trees on ice floes?

Of course not, at least not until the nutrients have been removed from
the topsoil its roots can reach - then you have a dust bowl where
nothing can grow.
