Any ideas whay this could be other than soil with fretilizer in it?

Soil contaminated by heavy metals?

I suspect it may mean grown in China where they have a habit of using
cheap Rare Earth minerals as fertiliser with allegedly good results.
Been going on for a couple of decades now (eg):

I'd be wary of the thorium content of such minerals YMMV.

I can't find anything much that isn't behind a paywall but if you have
academic access then a search on REE fertiliser China ought to get it.
