Hi Kevin,

President Mahmoud Ahmadinejad of Iran visited Columbia University and made a speech calling into question whether the German "ancients", (circa 1941-1946 AD) were trying to use Jewish people as the predominant feedstock for making Terra Preta in Poland and Austria.

The President of Columbia University, Lee Bollinger, did not like Ahmadinejad's view that the Holocost did not "really" happen.  He does not like Ahmadinejad's views on modern day Israel either.  He protested that the man came to a USA University in New York State and said the things he said to an audience WHO DOES NOT AGREE WITH Ahmadinejad's views.  Do you blame him?  Do YOU think the Holocost is a fable or an unproven hypothesis?

Archeaological evidence in Poland and Austria will show unequivocally that the German Military, lead by Adolf Hitler, did indeed incinerate PEOPLE and bury their charred remains into the ground.  They did not completely burn the Jewish people, because it wasted fuel.  They were inflamed until they were charred only (low temperature, lots of volatiles).

Lee Bolligner held his tongue!  I would be honored to be related to him.

Now, as to Robert Klein ... I don't think he reads.  I do read, extensively.  I have Johannes Lehmann's book, "Amazonian Dark Earths: Origins, Properties, Management".  You should buck up the $229 and get it.  All of what I will now say to argue against Robert's incorrect musings is supported by what is written in that book, which was developed over many years, by many more qualified people than by "gosh by golly" Robert Klein.

Amazonian Dark Earths, aka Terra Preta were formed in the Amazon RAINFOREST.  The identifying characteristics of the soil sites are; 1) high concentration of carbon, much higher than in surrounding soils (60+ times), 2) identifiable anthropogenic materials; pottery sherds, fish bone, other human artifacts, evidence nearby, man made elevated roads, etc., and 3) increased plant nutrient content in the soil (+greater soil organic matter content and enhanced fertility).  All ADE sites exist only around what verifiably were human settlements.  Many people lived near the sites and ate the foods produced on the land there.

This is the important point here, Kevin ... Are you watching?  ADE cannot be formed if nutrient losses exceed inputs.  Even if all of the corn stover (the wastes from a "food" crop) were put back into the soil as charcoal, the nutrient loss from farming the soil and then people eating the corn, would NOT create ADE.  The nutrient losses would exceed the inputs from putting the charred stover back into the soil.  The source of the charcoal in ADE had to come form a larger area, from a different place than the plants on the site.  The source of the charcoal in ADE is assumed to be from both primary forest and secondary forest around the settlements.
There are not enough nutrients in just fish bone and the night soil and all of the organic wastes from the crop.  Nutrient inputs MUST exceed losses.  Even if it was illegal to not shit in the fields, or to not throw all of the organic compost garbage in the field, there could NOT be formation of ADE.  The higher nutrient inputs had to come from other plants.

"Swidden" agriculture is when a plot of land is cleared for farming, by burning away the vegetation.  This is widely practiced to this day in South America.  It is a pronounced problem.  Ask Lou Gold.  Ask Johannes Lehmann.  Ask Christoph Steiner.  They have all stood there in Brazil and seen this.  This is not a sustainable method of agriculture.  You must know that the ancient Amazon people could not add industrial fertilizers to their fields.  THERE WERE NONE!  Today, the people who "slash and burn" to farm, cannot afford adding fertilizers.  When the plot is worn out, i.e. has no more fertility, has no more nutrients, because they have been lost to the crops, then they move on.  They are not, nor could not form ADE even, if they charred all the wastes from their crops.  Neither could the ancient Amazonians have done this.  The nutrients are lost to the harvested crops!

So, they had to put charcoal in from plants that came from somewhere else other than the ADE site.  They had to put in charred biomass that had more nutrients in it then they took out.  They had to throw in night soil, fish guts, fish bones, and charred biomass from other places, than the plot they were making ADE on.  They did not practice swidden agriculture.  They would not have been able to stay in one place (which they did, building settlements and forming ADE for centuries), unless they got the biomass to make the char from a bigger area then they were making ADE on.

It has been verified by pollen analysis of the ADE, that it contains palms (not corn stover), possibly house thatch (Sombroek et. al. 2003).  That is from the book, too.

I am repeating myself.  This is NOT my theory.  It is one developed by hundreds of other people who have the skills to study these kind of things; historical anthropologists and soil scientists.  Since I am neither, I just choose to research their work, read it, and not make shit up as I go along, like Robert Klein seems to do.

Now, ... Methane-CH4 from slow charring in dirt mounds.  It happens.  

Look here:  http://en.wikipedia.org/wiki/Methane<about:blank> ... It says (and this is not the only source which says this):

"Methane in the Earth's atmosphere is an important greenhouse gas with a global warming potential of 25 over a 100 year period. This means that a 1 tonne methane emission will have 25 times the impact on temperature of a 1 tonne carbon dioxide emission during the following 100 years."

He has not done this yet, but he does promote the large scale practice of it!  "50 times on every acre of every corn field!"

Robert IS wrong about suggesting that Methane-CH4 is not a problem from "open air" smoldering of biomass to make charcoal.  Ask Michael Bailles.  Ask Stephen Joseph.  Ask Tom Miles.  Ask Adriana Downey.  Ask me again!

Hug reality, Kevin, ... not musings, not ponderings, not dreams, not guesses.

Regards,

SKB

  Why do you feel his hypothesis is not viable? Can you suggest a better

  Goodness Gracious!! The gall!! :-)

  This is conjecture on your part.

  And I wish you would provide a better hypothesis, or show where he is 
  wrong with fact and evidence, not just your own opinion.

  Who said anything about large scale?

  How many man-years of Amazonian Indians running around their corn fields 
  making char would it take to equal the the CO2 equivalent of a standard 
  600 MW coal fired power plant?

  So, who else disagrees with his basic hypothesis?
