Interesting article on soil, how we are steadily degrading it with current agricultural techniques, and some efforts that are being made to remediate the problem. There are some challenges to the technology, as mentioned in the article.
Quotes:
"The potential power of biochar lies in this closed loop production process , where agricultural practices involving biochar production see increasing returns of crop yields, energy and soil fertility over time."
"Some industry participants believe that energy, rather than agriculture, will be the key driver for adopting biomass pyrolysis."
"Agrichar – A solution to global warming ?" (shown below) in the lead up to an international biochar conference in Terrigal, NSW, which included Tim Flannery talking about the potential for sequestering gigatonnes of carbon in the soil.

In Harrisonburg, VA the new Rockingham Hospital and JMU are collaborating on a 10 acre permaculture & produce farm to feed both institutions using Biochar protocols.
The Rest of the Biochar Story:
Charles Mann ("1491")in the Sept. National Geographic has a wonderful soils article which places Terra Preta / Biochar soils center stage.
I think Biochar has climbed the pinnacle, the Combined English and other language circulation of NGM is nearly nine million monthly with more than fifty million readers monthly!
We need to encourage more coverage now, to ride Mann's coattails to public critical mass.
Please put this (soil) bug in your colleague's ears. These issues need to gain traction among all the various disciplines who have an iron in this fire.

I love the "MEGO" factor theme Mann built the story around. Lord... how I KNOW that reaction.
I like his characterization concerning the pot shards found in Terra Preta soils;
so filled with pottery - "It was as if the river's first inhabitants had
thrown a huge, rowdy frat party, smashing every plate in sight, then
buried the evidence."
A couple of researchers I was not aware of were quoted, and I'll be sending them posts about our Biochar group: http://tech.groups.yahoo.com/group/b...guid=122501696

I also have been trying to convince Michael Pollan ( NYT Food Columnist, Author ) to do a follow up story, with pleading emails to him
Since the NGM cover reads "WHERE FOOD BEGINS" , I thought this would be right down his alley and focus more attention on Mann's work.
I've admiried his ability since "Botany of Desire" to over come the "MEGO" factor (My Eyes Glaze Over) and make food & agriculture into page turners.
It's what Mann hasn't covered that I thought should interest any writer as a follow up article.

Given the current "Crisis" atmosphere concerning energy, soil sustainability, food vs. Biofuels, and Climate Change what other subject addresses them all?
Biochar, the modern version of an ancient Amazonian agricultural practice called Terra Preta (black earth), is gaining widespread credibility as a way to address world hunger, climate change, rural poverty, deforestation, and energy shortages… SIMULTANEOUSLY!
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,10X Lower Methane & N2O soil emissions, and 3X Fertility Too. Every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration.
Carbon to the Soil, the only ubiquitous and economic place to put it.
