[Terrapreta] Tons of dry mass production per ha/ y

[Gerald Van Koeverden]

Nickolaus,

100 odt/ha/yr, of high grade feedstuffs!

It makes the extension in North America to promote switchgrass,  
willow and miscanthus - purely as crude undigestible fuel biomass -  
at little more than 10 odt/yr, look silly...

Though as feedstuff your moringa oleifera is certainly worth more, if  
converted into charcoal, you could theoretically produce 30 tons/yr  
of charcoal worth $200/ton on one hectare of land...??
