Lynton,
Yes we can know total P in any given soil sample. The process is to dissol=
ve the sample in concentrated nitric acid. The P can then be determined. =
This is the same test the State of Washington prescribes for heavy metals i=
n fertilizers. It's a standard test that's been around a long time.

Oh Great, so we can't actually know Total P? I guess to do it we would h=
ave
to
grind the sample to the finest molecules and test that...
Maybe burn it with a laser till its all gas, and analyse that...
(is this practical?)
Lynton (who is even more amazed at how much he has to learn!)
