This is the BEST presentation I've seen on making biochar. Most other videos have you making a kiln of one kind or another, which is simply not practical for many of us. He shows that all you need is the fuel and a pit in the ground -- the rest is just a matter of how you feed the fire.

[@edibleacres]

Nice description here. I've been enjoying making biochar in cone pit for 5+ years and this method truly is ideal for diverse feed stock... One trick to offer up, in regard to getting a finer texture in your charcoal AND increasing efficiency... If you use the long stick you have for moving material around to really poke and agitate as the charcoal is being produced, you can pre-crush a lot of charcoal in the pit, help reduce ash formation, and speed up the whole process. Over time I've found I spend quite a bit of time poking/crushing/shifting material in the fire and at the end, the quenched material is often already a texture I'm happy with for inoculating and garden use.

[@REDGardens]

Thanks for the suggestion about using the stick. I'll definitely give it a try on my next burn.

i use a spade to crush the char while its still burning, to event out the surface before adding the next batch i think this way, there layer of crushed char will prevent oxygene from reaching underneath as easily i avoid the extra step of crushing it

[@donaldscott8398]

You could use a cement mixer and some rocks to crush the charcoal up. It should beat it to a powder fairly quickly.

[@REDGardens]

That would work. I have read mixed advice about how fine is best, and it seems that a variation between the size of pea and coarse sand is thought to be best.

[@thegeneralist7527]

@@REDGardens Great video! My recommendation would be a good little wood chipper. I used to have a chipper and it would made processing garden refuse much easier. The wood chips would be perfect for suffocating the fire during the charcoal making process. I am interested in the scientific reason why biochar is such an effective agricultural method. It would require some research, but many forests like the amazon exist in areas with nutrient poor soils. All the nutrients and carbon are sequestered in the vegetation, and once that is removed the soil has little residual productivity. Slash and burn agriculture in these areas rapidly depletes the soil because of nutrient runoff. Biochar captures these nutrients and locks them in place where roots systems can still access them. Just like nanotechnology surface area to volume ratio is of critical importance. Smaller particles have a much higher surface area and thus activity. The charcoal itself is fairly inert and long lasting, it does not break down quickly like wood, but can act as a PH buffer as well as a nutrient reservoir. It may also provide some protection against soil pathogens and promote a healthy soil microbiome. Have to go but you get the just of what I am saying.

[@REDGardens]

@@thegeneralist7527 That is an interesting comparison between biochar surface area and nanotechnology.

[@danielrose1392]

You can use a concrete mixer to crush to a defined size. Fill it, mount a fitting fitting screen across the opening and then run it with the opening facing slightly down. The particles will stay in as long as they are larger than the screen width. A little work upfront, but you can screen and crush a lot of material this way.

[@Logan.Bernart]

@@REDGardens The Generalist is spot on. High surface area hard carbon made from pyrolyzed cellulose nanofibers is currently being researched for use in improving sodium ion batteries. Your backyard biochar should contain a fraction of these high surface area pyrolyzed cellulose nanofibers as well. If you are interested in the battery research, these sodium ion batteries have the potential to replace lithium ion batteries in certain applications such as stationary renewable energy storage. This is important due to the environmental issues caused by lithium extraction and the global shortage of lithium driving up battery prices. Sodium ion batteries have the potential to make renewable energy storage much more feasible and affordable and pyrolyzed cellulose nanofibers could become a critical component in these batteries.

[@gobigandgohomeschool4882]

David the Good did an experiment and was very happy with the results.

[@brianwhite9555]

Here in SE Michigan, I take as much finished compost from my pile as I need for all of my spring plantings. Then I spend the rest of the growing season rebuilding the pile, mainly with alternating layers of fresh grass clippings, and leaves that I had stockpiled the previous fall. I also make charcoal during the growing season, adding it to the compost pile. I run my small Mantis tiller through the pile several times during the season, mixing the accumulated materials. I let the decomposing compost inoculate(activate) the charcoal. Your pit method seems to be working well for you. I like the particle size you end up with, and your method of activation. I've collected some small cookie (biscuits in UK) tins to use as retort chambers in making charcoal. I load them with sticks & twigs, wood chips, pine cones, make sure the lids are tightly in place, then set them atop a hot fire. Three small holes are drilled in the lids to allow escaping gases to burn off. When no more gases are seen venting from the holes, the tins are removed from the fire and allowed to cool completely. Like you, I crush the charcoal into smaller particles.

[@REDGardens]

I think your method of adding charcoal to the compost pile as you build it up is probably the best way to get it into your soil. The cookie tin method is a cool one as well, especially if you regularly have fires for other reasons.

I can suggest you two things to improve your biochar making: the first is to put a metal pipe rght down the burning charcoal and using a funnel, pump all the water from bottom to top untill water gets on the surface and let it cool. This will ensure you to stop any burning. Second tip is about grinding the char. I use a meat grinder and even if it's a bit slow it works. Also it can be automatized (big funnel with more biochar on top and a drill connected to the crank). Hope it can be helpful.

[@REDGardens]

Thanks for the suggestions!

[@mikedee8876]

[@REDGardens]

[@DovidM]

A retort can produce biochar more efficiently than the method shown, and with fewer emissions. There are also questions of economy of scale. Can enough biochar be generated from waste cellulose for a small site doing what is shown in this video? I don’t argue with small scale efforts that are less efficient. There is value in doing what is currently possible rather than waiting for large scale production of biochar using a retort. I believe, however, that a retort designed for the needs of multiple gardens is the end goal.

[@REDGardens]

@@DovidM Good questions and ideas. I think that this pit method is suitable for people with small scale gardens or explorations. And it also fills that gap that you mentioned about waiting for the large or more sophisticated equipment to be developed or become affordable. That was a big benefit for me. It also allows people like me to produce some char without any upfront costs, so that I can do some explorations about how useful the biochar could be within my context before I start to upscale. I imagine if things go well I will transition to using a retort of some kind, just as you mentioned.

Nice multi-purpose pit. I was thinking of setting up a pit like this with a few chairs for sitting around the fire when I just want to relax/cook, and tools use it for biochar at other times. Hadn't thought of it as a compost pit, but might also work, especially with a cover to keep the rain off.

Funnily enough, I had just watched Edible Acres take on producing biochar. Using a 1/2 SS euronorm food container with cover. He used his house wood stove, and mostly scraps trimmings and off cuts. Seemed to work well and easy to control, the small batch size balanced by the more intense heat which gave a fast, simple and controllable burn. He reported up to 4 burns per evening. Thanks again for showing us your experiments.

[@REDGardens]

I hadn't seen the Edible Acres video on biochar, thanks for the pointer. If I had a wood stove in my house I would definitely use a similar method, to make good use of the heat. A good way to burn smaller material as well, and an option if I used a wood chipper to manage the bulky pruning material.

[@edibleacres]

Both are legit ways to create biochar. This video shows a really amazing way to produce biochar with the 'feed stock' he has available which is a huge pile of loose, small branches and finer wood. Cone pit can process mountains of 'slash' and prunings in a crazy effective way. The wood stove style I use is excellent for small offcuts from a wood shop, or sweepings, or nutshells, or other smaller, more uniform material in a slower, more controlled way. Whats so great about this cone pit style is it really stands as a potent argument against needing to have a wood chipper. @RED Gardens - I would suspect you found a similar outcome, that cone pit really can process branch wood as fast as a small chipper!

We still do it, but the deer discovered the patch. This year we are covering the patch with row cover, on the theory that if the deer can't see the plants, they won't eat them...

You might be able to use a cement mixer to break up the charcoal into smaller pieces. Rock is broken in mining operations like this using mills. If the material breaks on its own or can break other particles, it's called an autogenous mill. You could also try adding grinding media, like steel balls, to the mix to help break the material down.

[@MorgsBrew]

Howzit! As usual, a very informative presentation of the data. I think we have been thinking and playing with biochar from a similar perspective. The car lasts 1000 years so application is probably more important than precision. To a degree. "Everything should be made as simple as possible, but not simpler". It made a significant difference for radish planted in a fine grain inclusion into a clay loam soil. I made a video where I demonstrate my double-barrel TLUD design and I wrote a short post about the method and construction with some discussion. I have since moved to the Kontiki style drum. I use a 350L steel pressure vessel which is cut in half. I welded the ends closed and now it sits on an old wheel rim. I can easily create 100L of biochar and because the vessel is sealed I can use the quenching water during the "charging" of it. Reduce the total water usage in the process. I try to make a batch per bed. About 70L int 7.5m2 beds mixed with compost and dug in initially. My TLUD video - kzbin.info/www/bejne/hnPJmp1uiLJjaLc

[@toddgillespie8165]

I've been using an old concrete feed trough as a burn pit; it's about 5' long, 3' wide, 2' deep. I tried some smaller sizes before, but didn't like all the extra labor involved to cut the prunings down to fit. With a large pit I can just throw on bundles of long limbs, then push whatever sticks out the end further into the fire as the rest of the limb is consumed. Another perk with the large size is that there is so much material piled in, the weight of the mass does a nice job crushing the lower layers of char into small bits. Afterwards I pile the char in layers with fresh cow manure and a bit of soil for microbes, then leave it for a season while the manure composts and leaches into the char.

[@REDGardens]

Sounds like a great system. The bigger, or longer pit makes a lot of sense, and I am planning to scale up for my next few burns. Thanks for sharing your experience.

[@toddgillespie8165]

I forgot to add that the fire is slowly destroying the concrete (turns it back into lime and gravel) so after a few dozen more batches it will probably be too cracked to use. I'm happy with this b/c I need to remove the trough anyway, and this is easier than sledgehammering it. I won't need any more biochar for years afterwards, but for a new pit I might see if I can find an old junked metal watering trough and bury it part way. Good luck with your research!

I use the same easy and low tech method to make biochar and it works really good. You can crush the charcoal with a stick while burning, just before adding the new layer of wood. Going this way, you avoid most of the dusty part of the job and get the perfect particule size!

Good idea about crushing with a stick while burning. Glad to hear it works for you.

Thanks for the good information breakdown.

This is it! :) Made some trials myself following the instructions of the Ithaka Institute. If anyone experiments with urine try to inoculate the full bottle/can whith some drops of buttermilk against the ghoulish smell that develops. It takes just some weeks to ferment to a sour and sweet smell.

Interesting point about the buttermilk and the smell. Thanks.

for a couple of years now i have been using the dark carbon rich soil from spots where i had made bonfires on the ground, in my opinion it grows better plants

[@REDGardens]

That is a very interesting observation.

[@MichaelFlynn0]

Ive been doing the same - the plants love all that free carbon

[@harryalcantara1756]

Thanks for the info

interesting the way you explain this made it so much cooler!

I have just recently found you and have really enjoyed your videos! However, I quite like THIS one, especially 😊 I have used an old roaster in our fireplace to make biochar following the method EdibleAcres used in his videos. But I have never tried his method of the cone pit. After watching this though, I might re-watch this one a few times and his videos again and give it a try! I like the amount of charcoal y'all are producing!

[@REDGardens]

Glad you found my channel. The method that EdibleAcres uses is great, especially if you already regularly use a wood stove. This cone pit method is great for bulk material and lighter stuff.

The best video!

Very much looking forward to your assesment down the line. Biochar to me always sounded quite homeopathic and frankly unscientific, but i trust your judgement and scientific mind and am ready to be convinced by actual results.

[@REDGardens]

It is interesting how we can perceive things differently depending on where were come across the information. I fist was introduced to biochar by through the scientists studying terra preta, and other agronomists, so I feel it has that scientific foundation. But lately I see biochar based content all over the place, and often not well supported or documented, with lots of wild claims, and I can easily see how people could suspect the validity of its use.
