I don't doubt the positive effects of biochar, especially in barren soils. But I haven't seen any peer-reviewed or scientifically-based field trials showing any significantly beneficial effects for home gardeners with generally healthy soil. I've read or heard many anecdotal reports from home gardeners that it "works" for them, but nothing remotely objective.

Riveting...thank you for your seriously focused, science based presentation. I'm making a portable steal cone kiln.. you inspired me!

I don't agree that biochar is for sandier soils it's for more compacted clay soils that have no aeration. Sand can be amended with a microscopic amount of clay diluted into water.

Biochar is the equivalent of a savings account at the bank, it only stores what you have saved. When correctly inoculated it can save nutrients for plants to withdraw as needed... I'm extremely intrigued by this 🤔

Growing up Gambia , our people have been using biochar ( old knowledge passed down with any Scientific Facts & Research ) in outdoor pit latrines ( if you have been to a rural area you might have used one of these ) to combat overflow . Now i understand why . Science is incredibly important.

Great info but Deborah said 'um' 6238 times in 45 mins😮

If I had this Lecturer in Africa as my teacher i will be holding a Phd right now. Simplifies, Explains clearly & thoroughly with facts & visuals.

soil in our farm (Philippines) is low pH, low organic matter, and then high CEC (no area is less than 25 CEC. what to do. we will try biochar this coming rainy season. mygreathanks and blessings

Outstanding presentation….we have converted our soil to a sponge for petrochemicals in this country…we need to get back to basics….we’ll done!😎

In California, communities are trying different ways to reduce waste streams into landfills. Would general community compost materials collected from curbside be available for conversion to biochar? Composting efforts often introduce challenges as material contaminated with pesticides get rolled into the finished compost.

Amazing, thanks so much for sharing!!!

Mind blowing lecture.

Many saying a cone shaped pit is a great system.

Is ther a way to document the degradation of average feedstock to biochar over a 10 year period?

I used to pine needles that I had in my yard, as biochar.

the audio is soabrasive !!

That map is very lacking. Like utah has very little color. Sure the state is 65% owned by the federal government since the constitution isn't followed, but like water retention by biochar would have a huge effect especially since weve been having a drought. And I'd assume since politicians continue to let water go to the ocean in california and now they're going to take out damns in california and hundreds of thousands of acres aren't even going to be planted that maybe with biochar they'd at least be able to grow a little grass. Maybe they get enough rainfall to grow grass without watering. Theyre really screwed thanks to politics and thanks to the USDA for letting them kill agriculture.
