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.

[@REDGardens]

Thanks!

[@nguyenai1337]

But still too many Oxygen for this method.

[@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

I remember when scientists first discovered the amazing Amazon soil that the ancients had made so fertile, even after hundreds of years. It was such a mystery as to how they had accomplished this. Thank you for your interesting and informative video.

[@teamgay]

I heard about that... what did they find?

[@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.

[@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 could probably produce some lye from the pit for soap making as it is at times way past biochar. It's Amazoningly incredible what we learn when observing nature! Thank you!!

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.

[@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.

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!

[@kenknutson1598]

I use a Weber kettle BBQ to char rose prunings. I have found that feeding the fire as fast as I can without smothering works,though the fire does get rather big. When the char stops flaming I put the lid on to smother the fire for about a half hour and then douse the fire to put out any smoldering material. I get a good amount of char and little ash.

With other people's research and experiments, it seems like biochar may not be worth the effort if your garden soil is already rich in organic matter and fertility. But it totally makes sense that if you have poor soil, it could greatly improve it over time. That is exactly what it did to the poor Amazonian soil.

We started doing this a few years ago, with a long rectangular bed. We put manure on top and planted pumpkins. I was thrilled to get about 30 pounds of pie pumpkins from 4 plants. The next year (which is when I heard the biochar really takes effect), we got 175 pounds from 4 plants, with what was supposed to be an 8 pound max in each, producing 20+ pound fruits. 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.

I almost never see ads on your videos. Is it because you deselected the box to have ads shown alongside your video or was the channel demonetised by KZbin? I'm only asking because I always allow the ads to play on channels that I like.

[@YourprogrammingnetworkCoUk]

Damian Penston KZbin increased the requirements for monetisation recently and their viewcount looks roughly around the tipping point so maybe not been monitized yet

[@REDGardens]

Hi Damian, glad to hear that other people also let the adds run! I have monetised the channel a while ago, but I have a policy of not turning on adds for new videos for at least a month. I am not so thrilled about add revenue, though I recognise it as a 'necessary evil' that makes the whole platform work. I especially don't want to subject patreon supporters to adds, who have already contributed to my channel for each video. If you are watching my videos shortly after I upload them then you shouldn't see adds - only for older content. A bit of a compromise. Also, I suspect that KZbin doesn't have enough add requests to get paid for putting one in front of every single eligible video that is watched. I did a bit of a test myself with a few channels, and only ended up watching occasional adds.

[@pansepot1490]

RED Gardens, other channels I follow give patrons early access to their videos (you’ll have to figure out how this works because I don’t know). I receive a notification from patreon with a link to the video which is ad free and not yet accessible to everyone. I’d suggest that you monetize your videos from the start, once you make them “public”. I have been told that the KZbin algorithm promotes monetized content because of course the platform makes money out of it. So monetizing should help increasing your viewers since KZbin itself would promote your channel. If you go through the trouble of making videos and as it’s fair you want a revenue from it you should do the things properly. Ask for advice or do some research on the internet. Your content is very good so aim for the best possible return for your efforts. Cheers!

[@REDGardens]

@@pansepot1490 Thanks so much for the feedback about this. The issue of issue of offering earlier access to patrons is an interesting one, but just doesn't feel right to me at the moment. I am planning to go down the route of offering additional content to Patrons instead, though I haven't done that so much yet. It is worth a rethink. I have occasionally wondered about if the algorithms favour monetised content, and how much difference it makes. Perhaps I'm not looking close enough, but I haven't noticed an increase of views once I turn on monetisation, or rather increase the types of ads. I should clarify that I turn on monetisation for each video from the start, but only for the 'display ads' on the sidebar. Then after a month I turn on the other ad types, especially the 'skippable video ads' ( I stay away from the 'non-skippble video ads'). I wonder if that makes a difference for the algorithms?

Burning dried tree branches in a pit is a good way to make biochar. To prevent them from turning into ashes, I recommend placing the branches on elevated soil and digging a pit to ensure that the smoke can escape, and the fire remains controlled, preserving the charcoal without it turning to ashes. This is the method we use to create charcoal: we start with freshly cut wood branches, add rice hulls, and burn them gradually until they turn into charcoal without any ash residue.

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!

[@jameskniskern2261]

I built a biochar kiln out of thin metal roofing material. It is about a meter across and about 70 cm tall. I bury the edges in the soil, and build the fire inside it. Because it is so big, I don't have to cut the wood pieces down nearly as much as you did. Made things MUCH easier and less work. In fact I had quite a challenge keeping up with it! I've made 2 large burns already, and it makes cleaning up the tree trimmings so much easier. I only use the waste/low value wood for biochar. If it can be used easily in my wood stove, it gets cut and stacked and waits to season out for the wood stove. Otherwise, it gets charred. I don't mind applying charcoal directly on top of the soil, like any other mulch. There is no nitrogen loss or other negative affects, and the microbes locally can colonize the biochar and start working. I also add it directly to our compost pile, and "run it through" the process there, and then it gets added to the soil as a topical amendment. Keep up the burn!

[@REDGardens]

Sounds like you have build a good system. The pit makes a lot of sense, especially when the fire gets really going, and you have a lot of material. Your approach to separating low value material from stackable wood is what I used for the beech tree. Do you find any issues with using material fresh, or undried in the pit? I like the idea of using the char as a mulch. Do you find that it migrates further down into the soil?

[@jameskniskern2261]

I started out using resinous dry wood to get the heat going for the fire, then later on, I was able to add less seasoned wood. Yes, the less seasoned wood slows down the burn, but the smoke released was actively burned by the heat of the pit/kiln. I was burning freshly cut black locust, pear trimmings, and even willow, honeysuckle vines and grape trimmings. I'll get back to you on the mulch approach, as this is the first spring I've been applying biochar in mass. I did research that even topical applications have beneficial affects to the soil, and seeing how well composting and mulching has already improved my soil without tilling or digging in, I can only imagine that it will be just fine in the future. But the key is to keep on mulching! Best of luck.

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

Thanks for the comment and the link.

I'm so glad I just found your channel. I'm going to join your patreon.

[@tepesSTM]

to crush use a leaf shredder with a bag on the discharge end, make sure the biochar is dry to not clog up the machine or but not toooo dry which will make a lot of fine dust.....I use the TLUD 55gal barrel method which is: load, light and check every now and then to see when it's time to put it out with water

[@REDGardens]

I'd try it out - if I had a shredder - as that sounds like a good way to process the char. I was going to build a TLUD burner like you describe, until I came across the pit cone method. I still have the barrel waiting. I might give it a try to see how the two methods compare.

[@levilowder2624]

I'm looking forward to your trials and updates on using this biochar in the garden.

[@REDGardens]

Yeah, sorry, I didn't get to those last year. Hopefully this season.

[@ganzip6038]

Brilliant dude! I was wondering how and what i needed to make this. I was pretty certain the amazonians didn't go through the fancy systems i see people making. Great explanation

[@REDGardens]

Thanks! Yeah, they probably used a simple method, but not sure it would have been this method.

[@brianalt3912]

@@REDGardens how has it been working for you? Is there a follow up video?

[@REDGardens]

@@brianalt3912 Sorry, no follow up video yet. Hopefully this year.

[@lisahodges8299]

This seems like a good method to start a raised bed mixed with compost? Birdy

[@aenorist2431]

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.

[@hitreset0291]

I have made 2 pyramid kilns to make char...the big one (1.5 mtrs at its widest pt at the top) is much better than the smaller one for doing alot of material (temp levels are better)...works amazing and have made 100s of kilos of char thus far...best ever to clean up waste branches & leaves & other difficult to compost stuff.

[@robrob7011]

This is they second video of yours that i have watched. You are incredible!! You do full research prior, then you show all aspects of what u did. You are one of the best youtubers!!! New sub over here!! :)

[@REDGardens]

Ah, thanks. That kind of comment means a lot. Glad you like my work.

[@Katydidit]

I agree!!

[@adus123]

some good ideas. I have tried making it my myself like you say its a pain to put out. I did make a load from wood chips no need to brak it up. I just add it to the compost heap then its read with the compost to go on garden.

[@REDGardens]

Thanks. I was thinking that it would be interesting to try to make biochar with wood chip using this cone method.

[@michaelmcclafferty3346]

Thanks for sharing this video. You are a very hard worker Bruce. It seems like you need a lot of wood to make biochar.

[@REDGardens]

It takes a fair amount of wood, and I don't think it is really useful unless you have access to a lot of wood.

[@robertlombardo8437]

I love making charcoal. So many uses, so easy to make. And we all know how interesting a little bit of lump charcoal gets, mixed with some powdered sulphur and some stump remover from the garden section... 😏

[@REDGardens]

Had to google that - cool!

[@tannerfrancisco8759]

I do it in my fire pit burning municipal wood chips. Add layer on layer similar as you do then to smother it out I use a heavy layer of wet leaves. It stays hot for a long time so have to be careful. But I can't douse my firepit--its cast iron and would crack.

[@szkielet137]

Thank you! Gonna do it the same way!

[@REDGardens]

Hope it works well for you.

[@pigtailsboy]

Maybe building a shell of harder pack in the cone, then when the fire has reached it's optimal burn point put a disc or metal plate over the top and pack soil around it. Could add dry soil to the fire before covering it.

[@watermelonlalala]

That's what I have been thinking of doing. The metal plate part.

[@donabellahardeneravlogs790]

Great idea Sir

[@cooperbee408]

Really cool idea thank you

[@WanderingVeteran]

Thanks for the good information breakdown.

[@REDGardens]

:)

[@heraldhivet2230]

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!

[@REDGardens]

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

[@jeffreydustin5303]

This is great info as usual. I am experimenting with Mel Bartholomew's square foot gardening method and believe the gardener could profitably replace the coarse vermiculite with charcoal.

[@REDGardens]

Thanks. Replacing the vermiculite with charcoal could be a very interesting approach, so long as the char was adequately charged. I have been dreaming of building a rooftop garden one day, and think biochar could make a great light weight component of the growing medium.

[@gobigandgohomeschool4882]

Thanks for the helpful video!

[@GotToThink4yourself]

Have you tried a chipper to crush the coals? Easy, fast and fine result.
