Hello all,

I'm curious to know exactly what laterite is.  I've seen it
mentioned in numerous aquatic plant books.  I've also
read that it is very beneficial to plant growth.  I would
like to know its composition, methods for using it, and
US sources where I can get some.
I have asked a local nursery and was told that the EPA band
its use in the US.  Comments please.
