[Terrapreta] alkaline soils

[Tom Miles]

Even though the inorganic components of some chars may make them more
alkaline can we assume that biochar has a soil- buffering capacity similar
to straws and other organic amendments?

See http://terrapreta.bioenergylists.org/avrdcsoilrhizo

 

It should help a soil resist rapid changes in pH.

Yes, of course.but what I like about TP is the way it makes you re-think
traditional soil-science paradimes and makes you question what you think you
know about soil, fertilisers, SOM,etc 

The pH question is just one. Something strange is happening. 
As you say little work has been done on alkaline soils and TP
(In fact many soil scientists seem to ignore highly alkaline soils
completely )

Thanks for you valuable inputs Chris.
