Terra Preta

Field Trials;
 I am field testing for the 09 corn season with JMU and consultation  Dr. Hepperly at Rodale Institute.

Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other

Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.

Charcoal from Comets, Asteroids and Wildfires
Tom Miles, May 28, 2007

There is speculation that pockets of charcoal that resulted in enriched soil came variously from comets and asteroids and resulting wildfires, as well as intentional burning. The latest comet event has been reported as 12,900 years ago in North America. See Science Daily:
Did A Comet Hit Great Lakes Region, Fragment Human Populations, 12,900 Years Ago? May 23, 2007

and National Geographic News:
Comet Wiped Out Early North American Culture, Animals, Study Says May 23,2007

Potential extraterrestrial causes of terra preta formation are discussed in the literature from Cornell University and elsewhere. It has also been debated on the Hypography Science Forum.


BBC: The Secret of El Dorado

In 1542, the Spanish Conquistador, Francisco de Orellana ventured along the Rio Negro, one of the Amazon Basin's great rivers. Hunting a hidden city of gold, his expedition found a network of farms, villages and even huge walled cities. At least that is what he told an eager audience on his return to Spain.

"No one ever saw again what Orellana described"
Dr James Petersen, University of Vermont
The prospect of gold drew others to explore the region, but none could find the people of whom the first Conquistadors had spoken. The missionaries who followed a century later reported finding just isolated tribes of hunter-gatherers. Orellana's story seemed to be no more than a fanciful myth.

A proven liar?
