hi geoff.

nice to see you are still working on organic matter.

we are hosting an intl conf. in october in asilomar (monterey) on
mechanisms of organic matter stabilization (mostly a focus on soil).

looking at relations b/t n c and mineral material.

i can send you more details as we progress in planning. but we made an
early announcement at agu.
