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 :-).
