Subject: No Laterite in US (was Soil Substrate)

I must disagree with Dr. Niall McCarten's statement that "Laterites are 
very uncommon in North America" and "Iron laterites are also uncommon and 
do not occur in pure forms in the US to my knowledge".  Dr. McCarten does 
not know the history of Birmingham Alabama.  The local soils (red clay 
type) are rich in iron, foundaries were built and Birmingham was a major 
industrial center for iron.  There was even a large statue of the Roman 
(Greek?) god of the forge, Vulcan, to commemorate iron's importance to the 
city.   I am not saying that all red clay US soils have iron nor do I 
insist on using the label "laterite".  However, there are soils that have 
high iron content in the US.  You just have to know where to look and what 
questions to ask.  I wish I were close enough to Birmingham to get some of 
this soil because the red clay I use only has a little iron in it.  But the 
pine trees certainly love it.
