I’m about 2/3’s of the way throu(have to get ready for work tomorrow and will finish it tomorrow nite). It is quite interesting that you post this and I’m reading two of Charles Mann’s books, 1491, about what the Americas were like before Columbus, and 1493, about the new world that Columbus helped to create. These two books between them show the civilizations that were all over the Americas in pre-Columbian times and the wrenching effect of the domesticated diseases the Europeans and Africans unknowingly introduced into a virgin population that had no immunity to these diseases. All the misery that diseases like measles, smallpox, chicken pox, and many others had caused for thousands of years in the Old World got compressed into a matter of decades to a hundred years in the New World with a mortality rate that probably exceeded 90%.
On a better note the discussion of the terra preta makes me realize i need to look into biochar and how to incorporate it into the sandy soils where I live(Keystone Heights, Florida

My heart is saddened by all the freedom-trashing phony man-caused GW, proven false ‘science’ spouted here and elsewhere by mere mimes and shills. Our planet is deficient in CO2 and plant life already under duress for this lack. CO2 buildup follows GW by 200-400 years in geologic records.

This false calculation pales alongside that one of pyrolosis which destroys most of the soil nutrients captured by vegetation. It also impedes the same mass’ production of soil microbes and teaming enzymes that eventually and naturally produce beautiful, nutrient-dense black, carbon-rich organic material.

I should know. Been producing these soils 40+ years to reform natural mineral soils into verdant gardens for customers and community gardeners. Folks, dig behind the vested interests that fomment these politically-correct diatribes on us then go wirh facts, not freedom and health-destroying deceptions.

For those who disagree, have you used natural decomposition of biomass and proven by 40 years’ practice they are inferior to biochar? If not, why not?

At leasr, hold your tongue untl your many years’ prothatve undeniable proof that nutrient conservatiin beats wasting this invaluable nutrition for plant, soul and food consumer.
