# This is a "Chisholm Original" that I just created. Basically, it is  
the kind of process that occurs when vegetative matter such as leaves,  
grasses and vegetative matter sink to the bottom of a pond and  
decompose, in an anaerobic process, liberating methane, and leaving  
behind a smelly "black goop."

It kind of sounds

# Yes, indeed!! That is exactly it. Consider an oxbow lake, on the  
Amazon River. It would be an excellent place for a Community to raise  
Tilapia, that feed on algae. All the Amazonians would have to do is  
throw in manure, to cause algae blooms, and they would get a large  
growth of Tilapia fish, which they could easily harvest. The fish  
waste would be high in phosphate and nitrate content, and that would  
perpetuate algae blooms, that are great for growing Tilapia, in "Green  
Water Aquaculture." If they did not harvest enough fish, and if the  
weather got too hot, reducing the water oxygen content, the remaining  
fish would suffocate. However, the "black goop" on the bottom of the  
Oxbow Lake, would be highly nutritious as a "fertilizer". It could  
easily be "dredged" by buckets from a canoe, and be taken ashore, for  
spreading on their nearby fields. That would explain the presence of  
lots of fish bones.

# As I understand it, this process is somewhat different from the  
"LTAHTC" process, in that it seems to go further down the process  
road, stripping more H and O off the original biomass, to produce a  
product higher in Carbon, and lower in H, and O, than would be the  
"black goop" produced in a swamp situation.

# It would be very interesting indeed to see comparative growth tests  
using the LTAHTC, AVA-CO2, and "Conventional Biochar" products.

Best wishes,
