Re: Aquatic Plants Digest V2 #5, Laterite

Laterite is a soil type. It is not exclusively a tropical soil. There are
lots of lateritic soils all over the world.  I cannot at this time remember
the source, but someone in the Minneapolis-St.Paul area in Minnesota
manufactures and markets a very effective artificial "laterite." Hopefully,
some one else on the list can remember the address, etc.
