[Terrapreta] manure biochar N-P-K question

[Gerald Van Koeverden]

Short-term perhaps, but if those sugars provide the initial impetus  
for such mircoflora to throughly colonize those charcoal particles,  
then very good things could result...??  All soil scientists know  
that 200,000,000 organisms live in a cubic centimeter of fertile  
soil, but none of them really understand the dynamics of their  
nutrient relationships...its way too complicated and thus rather  
unpredictable.
