I agree that phytoliths (plantstones) offer a cheap way to sequester carbon.
However it is not at all clear that phytoliths are retained in soils for
millenia on a large scale. Recent studies (I'm thinking of Alexandre et al
1997) showed that, in humid tropical regions at least, that soil phytolith
ly hope that I am wrong in my impressions, and stand
ready to be corrected by specific evidence and logic.

attributable to phytoliths would be, while perhaps impressive in pure
quantitative terms, insignificant in terms of the actual percentage slice of
the whole pie. I would be interested in Ryerson's gut feeling on this, and
those of similarly-qualified researchers.

I found "Grassland" by Richard Manning to be a good read. You may also want
to check out works by John McPhee, although these are more geology related.
