[Terrapreta] Long term effects of charcoal

Sorry for the delay in replying (I now have 2,000 email messages to work
though)
My theory is that RAIN dissolves nutrients such as nitrogen and this is
absorbed by the charcoal.
(It usually rains ever day at 2pm in the tropics!)

Lightening seems to play a much greater part in this process than we
previously thought possible.

It still seems pretty incredible that we can have 6,000 YO fertile soils in
the tropics.
Obviously something else is going on
