This is a good presentation. Up here in Chico I have a small plot where a gravel road was topped with biochar mixed with compost and now we grow vegetables in it. Biochar is that good. Yes, the gravel is still there.
-
thanks for the talk, gonna try this definitely and keep track of the experimental results
-
Ok now: Do this with the biochar, it seems like a great and wonderful idea. Please combine it with growing hemp and building with hempcrete because as the hempcrete hardens it also sequesters HUGE amounts of carbon from the cellulose inside the walls. Its also stronger and lighter then concrete and doest take 25 years to grow like timber.

Very good Lauren. Thanks
-
Excellent presentation!
-
Biochar - an ingredient in the future of sustainable agriculture.
-
It’s almost like somebody had an interest in this video not getting shared
-
Great presentation!
-
Good Talking ABout Biochar Very true and future all about climate change and here we have available Carbon Negative soooo Go for Biochar ..... Green Future Waiting for Us when we use Biochar Superb Amazing And Amazing Presentation Thank You Lauren Hale

Poor woman has the sound technologists mess everything up! Lol, horrible, but she took it live, like a champion! Kept pushing through! Good on her!
-
I want to talk at TEDtalk. So inspiring for me and your presentation is good.
-
very informative and educational video Ms. Lauren Hale... more biochar topics please.. What is Teripreta? please elaborate
-
I live in Australia & have searched around for biochar still to no avail to find it in any nurseries etc.
-
tera preta... biochar was the solution of the past, spanish anglos killed the origional civilization builders and now anglo descendants rediscovering what they destroyed
-
Where can I find the plans or DIY guide to make the pyrolisis kiln (biochar kiln)?
-
I am curious about the weight of biochar added into the small bucket ? does anyone know that ?
-
Actually, amending with Biochar would initially take out nutrients unless it is charged first. What is the net Carbon sequestration for creating the Biochar? Pyrolysis requires heat.
-
Hmm... It seems like a catch-22, but I need more information to be sure. Showing us the chemical reactions would've been nice.
-
Can someone explain what fuel is being used to burn material at “high heat and low oxygen” levels? Sounds to me like a very high consumption of fossil fuel is required. If you want to feed the world and sequester large volumes of carbon in the soil without burning, listen to Gabe Brown, Joel Salatin and others and look at the numbers they’re creating in carbon content of their soils with multi species grazing.

CO2 was at 460 ppm in 2007 according to Billy Meier and the Plejarens. So, it' much worse than we realize.
