Carbon Sink
I am progressively getting convinced that planting tree is NOT a good carbon sink, nor is sequestration in deep well or ocean bottom. Carbon captured in trees is liable to be released back into atmosphere when it is harvested. Deep well and ocean carbon sequestration are subject to earth quarks and untested in sufficient scale.
Do I have a solution? I think I have.
It is biochar. Terra preta has been around for thousands of years and remain stable as carbon. It was estimated that only 2mm thick layer covering all the earth surface with biochar would revert the CO2 back to the pre-industrial level. If all the “excess” carbon dioxide in the atmosphere were converted into carbon and spread across all the earth’s arable lands, there would be 17kg of charcoal per square metre, in a layer 8cm thick. That’s not an unfeasible notion. The Gardening with Biochar FAQ mentions biochar application rates of around 5kg/m2. On the other hand, photos of Terra Preta soils show black layers that are many centimetres thick, so they must contain far more than 17 kg/m2 of carbon. [source]
The task is to develop a business model to make producing biochar and burying into soil economically attractive to investor. Anyone?

Biochar Soil Technology.....Husbandry of whole new orders of life
Biotic Carbon, the carbon transformed by life, should never be combusted, oxidized and destroyed. It deserves more respect, reverence even, and understanding to use it back to the soil where 2/3 of excess atmospheric carbon originally came from.
We all know we are carbon-centered life, we seldom think about the complex web of recycled bio-carbon which is the true center of life. A cradle to cradle, mutually co-evolved biosphere reaching into every crack and crevice on Earth.
It's hard for most to revere microbes and fungus, but from our toes to our gums (onward), their balanced ecology is our health. The greater earth and soils are just as dependent, at much longer time scales. Our farming for over 10,000 years has been responsible for 2/3rds of our excess greenhouse gases. This soil carbon, converted to carbon dioxide, Methane & Nitrous oxide began a slow stable warming that now accelerates with burning of fossil fuel.
Wise Land management; Organic farming and afforestation can build back our soil carbon,
Biochar allows the soil food web to build much more recalcitrant organic carbon, ( living biomass & Glomalins) in addition to the carbon in the biochar.
Biochar, the modern version of an ancient Amazonian agricultural practice called Terra Preta (black earth, TP), is gaining widespread credibility as a way to address world hunger, climate change, rural poverty, deforestation, and energy shortages… SIMULTANEOUSLY!
Modern Pyrolysis of biomass is a process for Carbon Negative Bio fuels, massive Carbon sequestration,10X Lower Methane & N2O soil emissions, and 3X Fertility Too.
Every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration, Bio-Gas & Bio-oil fuels, so is a totally virtuous, carbon negative energy cycle.
Biochar viewed as soil Infrastructure; The old saw;
"Feed the Soil Not the Plants" becomes;
"Feed, Cloth and House the Soil, utilities included !".
Free Carbon Condominiums with carboxyl group fats in the pantry and hydroxyl alcohol in the mini bar.
Build it and the Wee-Beasties will come.
As one microbiologist said on the Biochar list; "Microbes like to sit down when they eat".
By setting this table we expand husbandry to whole new orders of life.
This is what I try to get across to Farmers, as to how I feel about the act of returning carbon to the soil. An act of pertinence and thankfulness for the civilization we have created. Farmers are the Soil Sink Bankers, once carbon has a price, they will be laughing all the way to it.
One aspect of Biochar systems are Cheap, clean biomass stoves that produce biochar and no respiratory disease. At scale, the health benefits are greater than ending Malaria.
A great example;

The biochar Fund is also doing amazing work in the developing world;

The USDA-ARS have dozens of studies happening now to ferret out the reasons for char affinity with MYC fungi and microbes, but this synergy is solidly shown by the Japanese work, literally showing 1+1=3
Senator / Secretary of Interior Ken Salazar has done the most to nurse this biofuels system in his Biochar provisions in the 07 & 08 farm bill,

This new Congressional Research Service report (by analyst Kelsi Bracmort) is the best short summary I have seen so far - both technical and policy oriented.

Given the current "Crisis" atmosphere concerning energy, soil sustainability, food vs. Biofuels, and Climate Change what other subject addresses them all?
This is a Nano technology for the soil that represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.
Carbon to the Soil, the only ubiquitous and economic place to put it.

Biochar Studies at ACS Huston meeting;
Most all this work corroborates char soil dynamics we have seen so far . The soil GHG emissions work showing increased CO2 , also speculates that this CO2 has to get through the hungry plants above before becoming a GHG.
The SOM, MYC& Microbes, N2O (soil structure), CH4 , nutrient holding , Nitrogen shock, humic compound conditioning, absorbing of herbicides all pretty much what we expected to hear.

Company News & EU Certification
Below is an important hurtle that 3R AGROCARBON has overcome in certification in the EU. Given that their standards are set much higher than even organic certification in the US, this work should smooth any bureaucratic hurtles we may face.

EcoTechnologies is planning for many collaborations ; NC State, U. of Leeds, Cardiff U. Rice U. ,JMU, U.of H. and at USDA with Dr.Jeffrey Novak who is coordinating ARS Biochar research. This Coordinated effort will speed implementation by avoiding unneeded repetition and building established work in a wide variety of soils and climates.

Hopefully all the Biochar companies will coordinate with Dr. Jeff Novak's soils work at ARS; http://www.ars.usda.gov/pandp/people/people.htm?personid=24434
I spoke with Jon Nilsson of the CarbonChar Group, in their third year of field trials ;
An idea whose time has come | Carbon Char Group
He said the 2008 trials at Virginia Tech showed a 46% increase in yield of tomato transplants grown with just 2 - 5 cups (2 - 5%) "Biochar+" per cubic foot of growing medium. http://www.carbonchar.com/plant-performance
