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.

Sustainable Farm Scale Income producing Carbon Negative Fuels, Fertilizer, Food and Co-Products.
Danny Day, EPRIDA, United Nations Commission on Sustainability, May 7, 2007

Small farms can reverse global
warming by
1. Producing the fuels needed to grow their food crops.
2. Improving soil productivity on existing crop land.
3. Improving biodiversity to increase farm co-product income.
4. Taking part in producing terra preta soils.

Carbon negative energy to reverse global warming
Danny Day, EPRIDA, A posting to Energy Resources Group on Yahoo 2004

A recent symposium (EACU) at the University of Georgia in Athens, GA,
USA brought together a group representing scientists from chemistry, archeology, physics, anthropology, microbiology, soil scientists, agronomists, renewable energy research, and representatives from DOE, USDA and industry. The focus was to look at the evidence for massive historical carbon utilization, current research and how carbon negative energy could be economically deployed today.
