Outline

1	"ASABE – CSBE Conference," ASABE – CSBE Conference, Pacific Northwest Section Bridges to Sustainable Agriculture September 9 – 11, 2010 Lethbridge, Alberta
2	Emphasis is on reducing emissions
3	Soil Carbon Sequestration
4	Energy > Water > Enhanced Growth> Charcoal
5	Charcoal > Soil Enhancement >Terra Preta
6	Focus on tuning land portion of carbon cycle Carbon sink in soil larger than atmosphere (1500 vs. 750 billion tonnes) Annual exchange by plants is huge. (About 120 billion tonnes/year) Humans control on order of 24 billion tonnes /year Fossil fuel emissions about 8 billion tonnes annually
7	Interest in the concept grows 2004 – Conference in Georgia 2007 - Internet discussion lists established by Erich Knight, Michael Bailis, Ron Larson, and Tom Miles Information spreading – research projects underway 2010 - concept has “gone viral” at least within the green community
8	Dream or reality*
9	Top 5 Problem List
10	5 - How much credit for CO2 reduction?
11	4- Air pollution?
12	3 - Clean production processes needed?
13	2 - Impact on soil biotic processes?
14	1 – Will biomass productivity increase?
15	Recap
