[Terrapreta] TP growing back--was: TP theft.

[Sean K. Barry]

Hi Kevin,

1: There are two kinds of Terra Preta... Natural and Man-made.

2: Natural Terra Preta deposits are made as a result of eutrophication 
of fresh water bodies. (Lakes, ponds, sinkholes, marshes, river margins, 
etc)

3: Man-made Terra Preta Sites can be made as follows:
3:1 By partially draining a natural Terra Preta Site.
3:2 By taking naturally made Terra Preta from its site of manufacture, 
and spreading it on land to increase its fertility
3:3 By making char from biomass and mixing it in with local soil, to 
increase its CEC

What are your thoughts?

Best wishes,

Kevin

I'm not real sure that the Pre-Columbian people in South America were really into managing the cation exchange capacity (CEC) of the soils yet?
