[Terrapreta] Biochar and the nitrogen cycle

[Michael Bailes]

Interesting article thanks
I was not aware that nitrogen was a"problem" except' in excess and in
run-off into creeks rivers dams etc.
Char should decrease such run-off.

I am a bit puzzled by how it gets into the atmosphere by combustion as the
article says.
If someone could help me with the chemistry, and explain why it is a problem
I would appreciate it


I have often wondered if one of the reasons char works so well in the
tropics is because it captures the N dissolved in rainfall.
 Given that it rains every afternoon, would char act as a N reservoir and
sink, in such climates?
Would Char therefore be less effective in climates such as Australia where
rainfall is erratic and often rare.
