Thought I'd pass it on.

Note to @Quagulator and his old question in the 90 Gallon Custom thread..

Thanks for the link @jeffkrol

Note the units in the CEC analysis, it states nM/100 grams. A quick search hasn't given me an answer if this is equal to MEQ/100 grams, which I'm more familiar with, but judging by the stated High / Med / Low range it looks as if it lines up.

Also note ADA is right in line with what we've been throwing around - around 30 MEQ/100g (or nM/100g as the link states)....

Lots of good info in there for anyone wanting a good read / some values to go along with there soils.

Units Milllimoles /100g for whatever that is worth. Assume it's equiv to milliequiv/100g

another example of its use:

More weirdness..

meq/100g is numerically the same as cmol/kg.
