The Biochar Reddit
Biochar - charcoal used as a soil amendment. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years. Like most charcoal, biochar is made from biomass via pyrolysis. Biochar is under investigation as an approach to carbon sequestration. Biochar thus has the potential to help mitigate climate change via carbon sequestration. Independently, biochar can increase soil fertility of acidic soils (low pH soils), increase agricultural productivity, and provide protection against some foliar and soil-borne diseases.
Terra preta - a type of very dark, fertile manmade (anthropogenic) soil found in the Amazon Basin. It is also known as "Amazonian dark earth" or "Indian black earth". In Portuguese its full name is terra preta do índio or terra preta de índio ("black soil of the Indian", "Indians' black earth"). Terra mulata ("mulatto earth") is lighter or brownish in color.
Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, and manure to the otherwise relatively infertile Amazonian soil. A product of indigenous soil management and slash-and-char agriculture, the charcoal is very stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients.
Slash-and-char - an alternative to slash-and-burn that has a lesser effect on the environment. It is the practice of charring the biomass resulting from the slashing, instead of burning it as in the slash-and-burn practice. The resulting residue matter charcoal can be utilized as biochar to improve the soil fertility.

Rice U scientists: Cooking temperature determines whether 'biochar' is boon or bane to soil

I'm wondering if anyone has ever tried this: what if your flame-capped kiln was a short trough, where you add feedstock at one end, and the other end feeds into a chute that goes into a bin of water? You shove stuff towards the chute as it pyrolyzes, then finally it goes down the chute for quenching.
Hi, i made for the first time my biochar in my kon-tiki, but i do not know which kind of results i reach it. I followed each step in order to make it and now am wondering : how is it possible to check if i made a Good (or less) BioChar ? Thx
We're celebrating Earth Day (and workbook release) by Standing up to Climate Change with Carbon Negative outdoor Cooking while creating BioChar.
Build your own Estufa Finca Design 5 gallon BioChar Stove by following step by step photo instructions used in our in person workshops the past decade.
Workbook on Sale - Earth Day, April 22nd through May 1st 2023
This biochar stove works great as an efficient (virtually) smokeless fire pit or freestanding carbon-negative BBQ in your backyard or community garden WHILE creating biochar!
Using only dry wood waste as fuel, this clean-burning stove is great to have as a fire pit grill and to use for emergency preparedness. At the same time, this stove also creates biochar for long-term soil improvement, locks away carbon for thousands of years, and other environmental gains.

I'm new to the biochar world. Tonight we made black beans in the Instant Pot, and I strained off several cups of "bean juice." Normally I'd feel bad about the waste and just pour it down the sink, but now I'm wondering if I could add that to our biochar instead.
I realize they're both alkaline, but I don't know if that would cause a problem.
Hey All,
We have a really fantastic event next Wednesday at the Tooele landfill in Utah -- CHARPOLOOZA!
Featuring the CharBoss, Big Box Biochar, and Ring of Fire biochar production systems.
This will be rad. You get to see fire, biochar, and talk soil science with some big hitters in the space. We are arranging press interviews for those interested in such things.
Hope to see you there!

Can anyone recommend a good lab for getting my biochar tested? Preferably east coast but anywhere would be fine.
I'm wondering if I'm just wasting my time adding charcoal to my soil if it's all just going to be broken down by bacteria in a few years.
In many places there is an active push to switch homes away from propane and onto electricity as part of decarbonization. This potentially means that there will be a growing number of used propane tanks out there that nobody wants, and it might be interesting to think about how we can take advantage of that resource to increase biochar production. (Personally, I'm thinking about Hookway retorts.)
