Sequestration in soil must mean micriobial/fungal metabolism (biomass, net
primary productivity ?) which is precursor to soil health and availability
for plant growth ?? what is role of physical chemistry of parent
substrate? and biogeography? somebody needs to do a SOILS conference to
address and & in preparation for an (sub-)urban/community ecosystem based,
biodiversity indicator plant//animal///soil metabolism (GEIS ?) planning
process? to manage C sequestration and mass balancing of
local/regional//point source greenhouse gasses and/or airborne polluntants?
Is the farm bill a planning process?

Subject: Re: composting conserves more C ?
Thank you Joel for this reference. However, I recall that the previous
discusion was concerned with several effects, not just "C stabilization",
which is the purpose of composting to begin with. There was also a question
of the effects on soil biology and structure of raw MO (mulch) vs.
application of compost.
