Do You Create Biochar?

[@angel_I_s]

Excellent explanation of the distinction between biochar and charcoal. Many on the internet confuse the two. Yours is the first clear distinction. Its not that one is better than the other but the distinction is necessary. Biochar in the soil is a world apart from charcoal in the soil. You are my GOAT today. Dave. An avid gardener, amazed by nature's simplicity and complexity combined. It keeps me humble and awake to the BS in all the other stuff.

[@williamodell8634]

Geoff, I live in Florida, USA and I have a 10,000 sq. ft. no till Organic garden area. The growing media is almost pure sand and any compost added to my beds is very short lived. I just can not keep enough Biomass in my soil, it is such a big project every year to keep soil fertility at usable levels. I discovered Biochar a couple of years ago, being blessed with 100 Oak trees this gives me Leaf Mold compost and a large volume of wood in which to make my own char. I have been adding Biochar to my beds each time I add compost at least three times a year. The results have been a major improvement to all my beds. My work load and associated growing costs have been greatly reduced.

Good intel about testing biochar by washing it off your hands. I've never heard that and I'll test it the next time I make some. Lots of method for making biochar, lots of ways of baking wood until the gas comes out. The particular method that's worked best for me is similar to this except I don't use the second smaller barrel. Instead I load the whole 55 gallon barrel with wood and start a fire on top of the pile. Let that burn down beneath the rim, a good and hot normal fire, then put on the top with the chimney. It should roar through like a rocket stove. If you do it at night you can actually see the barrel glowing red near the top. The next bit it to start choking off the oxygen by piling sand or dirt over the bottom air holes, not completely, but just enough to burn off the volatilizing gasses but not enough to burn the coals. If you cut the oxygen off too much you can often see the gas catching fire as it exits the chimney. The super hot par of the barrel will move down the barrel until it reaches the bottom, at which point you cut off all the oxygen from the bottom and cap the chimney top. You might burn off any escaping gas with long nosed lighter or blowtorch. Let it cool down enough that it won't catch fire when you remove the top, the barrel should be half or so full of biochar.

[@louisegogel7973]

Thank you for sharing your method! Have you ever recorded your process on video so people can see it in action?

[@compostjohn]

Charcoal doesn't burn because of any residual oils in the matrix. It burns (cleanly) because it's pure carbon and when you heat it enough (ignition) it oxidises very readily in the air, combining with oxygen in a strongly exothermic reaction, which keeps the reaction going.

[@Change-Maker]

Thats what I was wondering as well...otherwise how could bio char or charcoal...keep burning and then turn into ash. Obviously its burnable. Love Geoff and love this simple method...but yes, still burnable.

[@compostjohn]

@@Change-Maker All humans get things wrong sometimes! I'm just a geek who loves biochemistry, and my deficits are I don't understand some jokes. But when it comes to carbon, I know my stuff!

[@joecrablone286]

Biochar is made in a very narrow range of temperatures without oxygen. Hardwood biochar can stabilize carbon for millennia, however it produces a lot of emissions up-front unless a quality retort is used (and the immediate nature of global warming means long-term carbon storage is less important than reducing emissions). Smouldering woodsmoke is extremely toxic and is rightfully regulated - it is preferable to buy biochar, where emissions are reduced via retort. Terra preta contains biochar, but has unique microbial elements that are not understood and properties that are yet to be replicated.

[@jameskniskern2261]

My understanding is that all charcoal will burn. The carbon readily oxidizes to CO2. Biochar has all resins, or volitile components burned off, with only the carbon and trace minerals remaining. Biochar also is inoculated with the beneficial soil bacteria, either from compost, compost tea, direct soil contact, or adding urine for the nitrogen component.

[@RushHourRecords]

Thanks!

[@erector5953]

Biochar or charcoal are made via pyrolysis ! *That means gasification in the absence of oxygen living 85 % of the dry mass intact* heavy carbon bounds contained in the Cellulose and the lignin parasites and form the insanely complex molecular structure that. Is biochar

[@johncossham9405]

Yes, my understanding is that biochar and charcoal are the same but biochar is prepared for use in soils. Lawton's hypothesis that charcoal burns because of residual tree resins is incorrect. Biochar, pre-inoculation, will oxidise and give off heat ('burning') if given an initial source of combustion. I've lost several retorts of char through taking the lid off too early and letting oxygen get to the still hot char. However, Lawton's method of making charcoal is almost the same as mine, I use a retort in a smokefree woodstove, so no heat is wasted, said on outdoor biochar manufacturing. My charcoal goes into working compost systems and is inoculated there, giving extra rich compost to sell on.

[@johncossham9405]

Sorry,typo, I wanted to say that outdoor biochar manufacturing did waste heat, as opposed to those of us who make it when we're using our woodstoves to heat our homes and cook on. Bloody autocorrect!

I just learned this from Dr Olivier Husson's free course over at Regen Ag. You can greatly improve Biochar by treating it with Ferrous Sulfate prior to burning. Unfortunately, he is an academic and gives long lectures with a terrible French accent. In the same section he talks about the benefits of paramagnetism (shades of Dr Arden Andersen). Paramagnetism refers to the magnetic attraction of minerals derived from volcanic rock (basalt.) Perhaps this ferrous sulfate increases the paramagnetism of the biochar. Yes. But how do we apply it? Do you have any suggestions. This could be a new advance in biochar. Andersen already sold me on basalt rock dust. Thanks in advance for your suggestions.

It is a great way to build humus on sandy soil - eastern Germany has this problem. The ZEGG community uses this "terra preta" to build their soil with great success. They claim that this is the best thing they have to keep their nutrients from being flushed down into the deep sand. They built a huge Steel Bowl with legs and heat it up a lot so only the gas from the wood burns and cover it with wet clay after it is finished to let it cool down. This process uses all the wood invested to make bio char, instead of wasting wood for fuel. The important point is to get it hot enough so only the wood gas burns.

[@frankstrie3214]

Great informative video, thanks Geoff. Could you use stainless Steel drums? And there seems to be talk about having to inoculate it, can you please expand a bit more on that. Thanks again.

The biochar is porous like a giant sponge, that is why it is great for water retention. If you put it in the soil as is, it will soak up all of the nutrients. Now that would be great for future plants, but your current plants suffer. So instead, I inoculate it first. I mix it with good sloppy worm castings and a little compost and let the mixture stew at least 48 hours. Now the char has absorbed all of those great biomes and will slow release it to your garden.

You could but keep in mind that the thermal capacity of stainless steel is much less than that of mild steel so you will likely require more fuel to reach complete pyrolysis.
