Dear Trudi,
I have seen no such pbls., but that does not mean they don't exist! Try the
archive at IOM3 - what pretends to be the IMM (Inst.Mng.&Metlgy.) these days -
there could be something there.
As an idea: using the foreign data as a baseline, maybe making climate and
water acidity adjustments, together with a bit of fine tuning allowing for rock
and soil types, might at least get you close to what you seek. You have
probably thought about this already, but I thought it worth a mention.
Not wishing to kick up the dust as with Happy Christmas last year, a Happy
New Year to You! - and to all those that I know obviously!
Regards, Bernard
