So would I infer from this then that the aquaria definition of laterite
is then just a broad term applying to most any soil substrate? The
physical properties then can vary from one manufacturer to another?
The research I have done thus far from scientific sources on the net
have a much clearer definition. If it is so commonplace that laterite
exhists in North america, then it only makes sense that it would be
documented by someone and known by someone, anyone in the scientific
community. I am only looking for answers clear and simple. I do not
think I am creating confusion, I am only bringing to the surface
confusion that is already there unanswered. My motives are purely
selfish...I simply want to know what laterite really is and where it is.
