Biochar - agrichar - Terra Preta

It's hard to believe this "quick-fix" carbon belief system
Just fuel up with more fossil energy and make more "Terra Preta"!

Informative and very inspiring: a source of real hope. Colin

Koporate Amerika and her foreign Nazi allies will kill this dead. It will be "proven wrong", "unessential", "overly rated" etc. etc. We are led by the filthiest and most self aggrandizing profiteers ever.

Yes the earth is getting warmer, it is called.... Sunshine... look at the real data and one will see that the "global warming" is just a scam. Bio char is a great thing it works. I am glad they are showing syngas, it is the awesome way to go.

James Hansen figures you could suck out 8 ppm of CO2 per 50 years using biochar.

That's not nearly good enough by itself. We need to get rid of coal power fast and that means nuclear.

Agrichar seems much more useful for soil fertility and production of industrial chemicals( don't waste the precious syngas making fuel for internal combustion engines; make ammonia for fertilizer and explosives, make raw materials for glue, plastics, pesticides, medicines...)

At 7:49 they show a test comparing a test bed with no amendments against one with chicken manure and char. That doesn't seem to be a fair test. Chicken manure is a fertilizer - of course it's going to do better.

Am I missing something?

i'm guessing that they use chicken manure becuase they have an arrangement with a chicken farm to collect biomass for making their gas... I doubt the fertilizer properties of the manure are the same once its been reduced to charcoal ...nutrients are destroyed when you apply that kind of heat

Actually, you are missing something.

She said "chicken-manure char", not "chicken manure and char".

She was clearly referring to char made from chicken manure, not a mix of chicken manure and char.

If you want to see an experiment in which there is a comparison of biochar+fertilizer vs. just fertilizer vs. nothing then see the "Promise of Biochar" video. In it, there is just such a comparison in a tropical area following use of traditional slash-and-burn techniques.

It was char produced FROM Chicken Manure ya fuckin Donkey!!
Its certainly is the way forward but how does one produce massive amounts of Char....

I wish they had used a char base other than chicken manure for their corn crop demonstration. Chicken manure by itself is a potent fertilizer. I would like to have seen a control group with non charred chicken manure. Interesting idea. Could provide a solution for poor soils.
