Terra Preta (TP) soils and their potential as one of the largest wedges for replacing fossil carbon energy should be a giant boon for Archaeology. The lost practice of a precolumbian culture being a saviour of western industrial society. This work funded by NASA will put some very hard numbers to the exact extent of the Kayapo TP culture.
(How many millions were they??)

Recent NATURE STUDY;
Sustainable biochar to mitigate global climate change
http://www.nature.com/ncomms/journal/v1 ... s1053.html
Not talked about in this otherwise comprehensive study are the climate and whole ecological implications of new , higher value, applications of chars.
First,
the in situ remediation of a vast variety of toxic agents in soils and sediments.

Second,
the uses as a feed ration for livestock to reduce GHG emissions and increase disease resistance.
Third,
Recent work by C. Steiner showing a 52% reduction of NH3 loss when char is used as a composting accelerator. This will have profound value added consequences for the commercial composting industry by reduction of their GHG emissions and the sale of compost as a nitrogen fertilizer.
Biochar Soils.....Husbandry of whole new Orders & Kingdoms 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. Agriculture allowed our cultural accent and Agriculture will now prevent our descent.
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.
Every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration (= to 1 Ton CO2e) + Bio-Gas & Bio-oil fuels = to 1MWh exported electricity, 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.
Microbes like to sit down when they eat.
By setting this table we expand husbandry to whole new orders & Kingdoms of life.
( These oxidised surface charges; carbonyl. hydroxyl, carboxylic acids, and lactones or quinones, have as well a role as signaling substances towards bacteria, fungi and plants.)
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 penitence 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.
Unlike CCS which only reduces emissions, biochar systems draw down CO2 every energy cycle, closing a circle back to support the soil food web. The photosynthetic "capture" collectors are up and running, the "storage" sink is in operation just under our feet. Pyrolysis conversion plants are the only infrastructure we need to build out.
To me, in the long run, the final arbiter / accountancy / measure of sustainability will be
soil carbon content. Once this royal road is constructed, traffic cops ( Carbon Board, see below ) in place, the truth of land-management and Biochar systems will be self-evident.
A dream I've had for years is to base the coming carbon economy firmly on the foundation of top soils. My read of the agronomic history of civilization shows that the Kayopo Amazon Indians and the Egyptians were the only ones to maintain fertility for the long haul, millennium scales. Egypt has now forsaken their geologic advantage by building the Aswan dam, and are stuck, with the rest of us, in the soil C mining, NPK rat race to the bottom. The meta-analysis of Syn-N and soil Carbon content show our dilemma;

The Ag Soil Carbon standard is in final review by the AMS branch at USDA. Both Congressional Ag Committees have asked for expansion of Soil Carbon Standard to ISO status.
Read over the work so far;
http://www.novecta.com/documents/Carbon-Standard.pdf
In my efforts to have Biochar's potential included, I have recruited several to join the list, briefed the entire committee about char when issues concerning N2O & CH4 soil GHG emissions were raised, fully briefed a couple of the 100 members when they replied individually to my "Reply all" briefs. The members cover the full spectrum of Ag interest.
With the Obama administration funding an inter-departmental climate effort of NASA, NOAA, USDA, & EPA, and now even the CIA is opening the data coffers, then soil carbon sensors may be less than 5 years away. I'm told by the Jet Propulsion Lab mission specialists responsible for the suite of earth sensing satellites, that they will be reading soil carbon using multiple proxy measurements in 5 years. Reading soil moisture to 3 foot dept in two year with SMAP, Reading GHG emissions and biomass from the tree tops down next year when the Orbital Carbon Observer (OCO, get it:) is rebooted, to 1 Ha resolution.
Then, any farmer can click "Google Carbon maps" to see the soil carbon accounted to his good work, a level playing field to be a soil sink banker.

Sowing Seeds With New Agricultural Carbon Accounting Tool Carbon dioxide emissions from agricultural activity in the United States can now be tracked with unprecedented resolution because of a method developed at Oak Ridge National Laboratory team led by Tristram West.

Global Clean Stove Initutive:
Another significant aspect of low cost Biomass cook stoves, that produce char, is removal of BC aerosols and no respiratory disease emissions. At Scale, replacing "Three Stone" stoves the health benefits would equal eradication of Malaria & Aids combined.
