FIELD OF THE INVENTION

[0002] This invention relates to the production and use of a nitrogen enriched carbon based fertilizer and soil amendment made during the pyrolytic conversion of carbonaceous materials which produce charcoal and the reaction of said charcoal with ammonia, carbon dioxide, water and other components generally found in flue gas emissions. The invention also relates to the optimization of that charcoal with mineral and plant nutrients to produce and use the combined materials as a soil amendment and fertilizer. The invention also relates to the use of the material as a way to economically store carbon and captured greenhouse gases in the soil.

I took the pictures when I visited Danny Day at Eprida last month.

The first shot is of the red Georgia clay before and after charcoal had been tilled in two years prior. The second shows some "structure" as a result of the charcoal treatment. The untreated had become very hard (compacted).

Three and four illustrate how tilth was improved. In both shots Danny

Time to Master the Carbon Cycle
Erich J. Knight, January 16, 2007

Man has been controlling the carbon cycle , and there for the weather, since the invention of agriculture, all be it was as unintentional, as our current airliner contrails are in affecting global dimming. This unintentional warm stability in climate has over 10,000 years, allowed us to develop to the point that now we know what we did and that now we are over doing it.

The prehistoric and historic records gives a logical thrust for soil carbon sequestration.
I wonder what the soil biome carbon concentration was REALLY like before the cutting and burning of the world's virgin forest, my guess is that now we see a severely diminished community, and that only very recent Ag practices like no-till and reforestation have started to help rebuild it. It makes implementing Terra Preta soil technology like an act of penitence, a returning of the misplaced carbon.
