“Black gold” makes me think of the Beverly Hillbillies -- you know, as in Jed Clampett and “Texas Tea.” But we're not talking oil, of course. The “black gold” of agriculture is actually a sustainable technology called "biochar" -- a charcoal derived from biomass that improves soil fertility and may help mitigate climate change. This stuff is well established having been used at least fifteen hundred years ago by farmers in the central Amazon basin. Their charcoal was derived from animal bone and tree bark and the basin today still contains some of the richest soil in the world. That's because the biochar is inert, and unlike manure and compost which breaks down pretty easily, it persists for thousands of years, in a pretty permanent fashion. It increases water retention, microbial activity and the mineral uptake of plants. And the process? Not as intensive as you might think. It's a heating process known as pyrolysis where organic residue is packed into a metal container, sealed, and heated to the charcoal point. As a climate change mitigator, biochar may not have a monstrous effect, but it is more likely to stay in the ground than a forest which might eventually get chopped down. It also appears to decrease emissions of nitrous oxide and methane, two major greenhouse gases. In one study, nitrous oxide emissions were reduced by 80% and methane emissions were suppressed completely when biochar was added to a forage grass stand.

It's true what our moms said...we are what we eat. In fact, it's truer than they thought. What I eat doesn't just affect me anymore, it affects all of us.
Unfortunately, the story of food can sometimes be complicated. But envirovores help each other out...which is why this blog will be bringing you news, tips, and information about food and the environment every step of the way.

the current news and links on Terra Preta (TP) soils and closed-loop pyrolysis of Biomass, this integrated virtuous cycle could sequester 100s of Billions of tons of carbon to the soils.
This technology represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.Terra Preta Soils a process for Carbon Negative Bio fuels, massive Carbon sequestration, 1/3 Lower CH4 & N2O soil emissions, and 3X Fertility Too.

After many years of reviewing solutions to anthropogenic global warming (AGW) I believe this technology can manage Carbon for the greatest collective benefit at the lowest economic price, on vast scales. It just needs to be seen by ethical globally minded companies.
Could you please consider looking for a champion for this orphaned Terra Preta Carbon Soil Technology.
The main hurtle now is to change the current perspective held that the soil carbon cycle is a wash, to one in which soil can be used as a massive and ubiquitous Carbon sink via Charcoal Below are the first concrete steps in that direction;
S.1884 The Salazar Harvesting Energy Act of 2007
A Summary of Biochar Provisions in S.1884:
Carbon-Negative Biomass Energy and Soil Quality Initiative
for the 2007 Farm Bill
Bolstering Biomass and Biochar development: In the 2007 Farm Bill, Senator Salazar was able to include $500 million for biomass research and development and for competitive grants to develop the technologies and processes necessary for the commercial production of biofuels and bio-based products. Biomass is an organic material, usually referring to plant matter or animal waste. Using biomass for energy can reduce waste and air pollution. Biochar is a byproduct of producing energy from biomass. As a soil treatment, it enhances the ability of soil to capture and retain carbon dioxide.

There are 24 billion tons of carbon controlled by man in his agriculture and waste stream, all that farm & cellulose waste which is now dumped to rot or digested or combusted and ultimately returned to the atmosphere as GHG should be returned to the Soil.
If you have any other questions please feel free to call me or visit the TP web site I've been drafted to co-administer. http://terrapreta.bioenergylists.org/?q=node
It has been immensely gratifying to see all the major players join the mail list , Cornell folks, T. Beer of Kings Ford Charcoal (Clorox), Novozyne the M-Roots guys(fungus), chemical engineers, Dr. Danny Day of EPRIDA , Dr. Antal of U. of H., Virginia Tech folks and probably many others who's back round I don't know have joined.
The International Biochar Initiative (IBI) conference held at Terrigal, NSW, Australia in 2007. The papers from this conference are posted at their home page; http://www.biochar-international.org/home.html

Terra Preta creates a terrestrial carbon reef at a microscopic level. These nanoscale structures provide safe haven to the microbes and fungus that facilitate fertile soil creation, while sequestering carbon for many hundred if not thousands of years. The combination of these two forms of sequestration would also increase the growth rate and natural sequestration effort of growing plants.

Genesis Industries, licensee of Eprida technology, provides carbon-negative EPRIDA energy machines at the same cost as going direct to Eprida. Our technical support staff also provide information to obtain the best use of biochar produced by the machine. Recent research has shown that EPRIDA charcoal (biochar) increases plant productivity as it sequesters carbon in soil, thus reducing atmospheric carbon dioxide.

If pre-Columbian Kayopo Indians could produce these soils up to 6 feet deep over 15% of the Amazon basin using "Slash & CHAR" verses "Slash & Burn", it seems that our energy and agricultural industries could also product them at scale.
Harnessing the work of this vast number of microbes and fungi changes the whole equation of energy return over energy input (EROEI) for food and Bio fuels. I see this as the only sustainable agricultural strategy if we no longer have cheap fossil fuels for fertilizer.
We need this super community of wee beasties to work in concert with us by populating them into their proper Soil horizon Carbon Condos.

I believe everyone's bank account will swell, Big Ag, small farmers, Bioenergy companies, most of all the soil's carbon account. So many problem birds killed by this single stone.
The old saw; "Feed the soil not the Plant" becomes;
Feed, Cloth, provide a furnished house, waste & water system, community center, health insurance and Job security to the Soil not the Plant!!
Let us all Please incant ritual supplications for a smooth transition to these new agricultural protocols.
Just for fun I leave you with The Terra Preta Prayer;
The Terra Preta Prayer
Our Carbon who art in heaven,
Hallowed be thy name
By kingdom come, thy will be done, IN the Earth to make it Heaven.
It will give us each day our daily bread and forgive us our atmospheric trespasses
As we forgive those who trespass against the Kyoto protocols
And lead us not into fossil fuel temptation, but diliver us from it's evil
low as we walk through the valley of the shadow of Global Warming,
I will feel no evil, your Bio-fuels and fertile microbes will comfort me,
For thine is the fungal kingdom,
and the microbe power,
and the Sequestration Glory,
For ever and ever (well at least 2000 years)
AMEN
