I forwarded the above post to Albert Thiel, his response follows:
Thank you for your message on laterite and for posting the web site address
to the newsgroup. I appreciate it.
Laterite from the Tropics is expensive as we know, so years ago I started
talking to mining companies to find out if we could find a similar product
here. I sent samples to several of them to make sure they knew what I was
It took quite some time for many of them to do anything about it because (I
guess) they did not really see a big market for this product.
After receiving samples from several companies and running tests on these
samples we settled on a product mined in Arizona that seemed to contain the
minerals and the iron we are so interested in for our plants and have been
selling that variety for quite some time now with great success.
Plants do real well and replacement is not necessary in the short run. The
variety we have seems to release nutrients for the plants over the long
run.That does not mean though that additional supplementation with Plant
Nutrients is not necessary. Laterite or Elaterite as some mining companies
called it, provides nutrients but not in sufficient amounts in tanks with
large amounts of plants rapidly enough. It is necessary but the release of
nutrients at the root level is slow. In tanks with lots of plants this
requires using addl nutrition so it is more rapidly available. Sort of a two
prong approach: root and supplementation.
Yes the Laterite we sell contains iron and I should probably add that to the
label to make that clear. That is my fault, I guess I assumed that one would
automatically infer that it did because it is laterite. I will change the
label when we produce new ones to reflect this.
I hope this answers your questions and if it does not and you need more
info, please feel free to ask more questions. You are welcome of course to
repost my answer.
