Duplarit is still leagal.

Being a cynic, I have to note that the processes in substrate that are
quantified by Cation Exchange Capacity (CEC) also only release nutrients 
to the plant roots "by adsorption".   And this also sounds a lot like 
what "chelation" does.  But I'm sure that Aqualine-Buschke really does
have some magic thing going on here :-).
