I dig up that post when collecting some info about aluminium
(alu* for the us).

Eating soil....

We had such aluminum discussions some time ago, and I recall the very
dangerous effects aluminium can have.
Now recently I thought of a mineral preperation to get some more
and more seldom minerals ... in the case our soil don't have it
sufficuently anymore.
I still have something called "Schindele Mineralien" and "Luvos"
which is actually ground soil...
Very old soild, not tuouched by agriculture I suppose.

So far so good, but the label of both say, this things have some 20%
of aluminium-oxid.
So at least some soils are rich of alumininium.
I suppose that this form of aluminium is rather inert,
as alu binds strongly to any oxidants.

Has anybody any information if aluminium problems to have been documented
from other sources than from metallic aluminium?

Somehow that "earth" makes a good feeling, despite a little sand-like
sound between the teeth for the first seconds :-)
