       Hmmm.  Must be a particular aluminum salt.  Most soils contain a good
bit of aluminum, usually bound up as extremely strange oxides incorporating
other elements.  If I remember my highschool geophysics correctly, aluminum
makes up 22% of the earth's crust.  Many clay types contain very high
concentrations of aluminum oxides.
Could be the second answers the first.
        I have a soil test here and it tests for Aluminum in parts per 
million.
        I started out interested in "Just Gardening" and organic looked great 
so from knowing next to nothing I've grown quite a bit.
        Clay soils are sometimes too heavy for Pot.  I think a sandy humus 
soil is good.  Then again, Clay soils with humus can be loose as well plus 
clay is known to hold nutrients.
