[Stoves] camel dung???

[Alex English]

Paul,
The 'biochar' paper you reference seems to be stretching the definitions 
a bit. 350C formation hits close to the bottom of the 'charring' range, 
200C is low torrefaction.  At 200C it is doubtful that there would be 
any recalcitrant carbon present. The raw manure performs well with lead 
too. This is all about phosphorus not sorption on carbon or even surface 
functional groups.
A rose by any other name....
but its probably my 'failure' to understand.
