Extrapolating from the numbers bellow, say a conservative overall 1/3 reduction of GHG soil emissions, what would that benefit be expressed in equivalent tons of carbon per acre?
ES&T Online News: Rethinking biochar
"Preliminary results indicate that biochar amendments to soil appear to decrease emissions of nitrous oxide as well as methane, which is a greenhouse gas 23 times more potent than CO2. In greenhouse and field experiments in Colombia, nitrous oxide emissions were reduced by 80% and methane emissions were completely suppressed with biochar additions to a forage grass stand, Marco Rondon of the International Development Research Centre and colleagues told participants at the U.S. Department of Agriculture Symposium on Greenhouse Gases and Carbon Sequestration in 2005. Lukas Van Zwieten and colleagues at the Wollongbar Agricultural Institute are seeing similar preliminary results, and Lehmann's group also has greenhouse and field data showing the same effect.
Possible explanations, Lehmann says, include biochar's influence on water-filled pore space, nitrification rates, and the microbial community structure."

Hey Folks, you too can experience the warm glow I get when I recieve replies like this;
Nardi, a scientist at the University of Illinois, writes in his newly published book, "Life in the Soil," that a square meter of healthy garden soil is home to 10 trillion bacteria, 10 billion protozoa, 5 million nematodes, 100,000 mites, 50,000 springtails, 10,000 creatures called rotifers and tardigrades, 5,000 insects and arachnids, 3,000 worms and 100 snails and slugs. Throw in the occasional mammal such as a chipmunk or a mole, and a salamander or two, and you get the idea that you don't have to travel to the Brazilian rain forest to luxuriate in the biodiversity at our feet.

Jim Nardi to me;
Dear Erich, Thank you for calling my attention to the Terra Preta technology. Yes, it is definitely of interest to me - and I readily inferred its vast promise from just my cursory reading . I shall continue looking over the vast amount of fascinating information you sent me and hope that I may speak with you about certain details after I learn more.
With much gratitude for sharing this information on Terra Preta, Jim Nardi"
