Biochar - Permanent Compost for Your Garden

[@philjulian2083]

I live in a long needle pine area, ( North Crolina) and collect bushels of needles in the fall from my yard and my neighbors. I pile 2 wheelbarrows (6 cu ft each) of the needles into a 10 ft long x 2 ft wide caterpillar and torch one end. As it gets glowing orange like a cigar, i rake out the glowing part, flip it to complete the burning, then douse it with a hose, this produces one 5 gal bucket of fine-rice grained carbon. (no crunching up necessary) (Process for one batch takes 10 minutes) I also have a worm bucket and collect the drippings, which is my "bio" microbe source, which I culture with sugar to increase the population, then pour the soup into the carbon and let sit for a few days. Then I spread it in the garden to simmer until spring. I produced about 36 cubic ft of carbon this way. ( six- 6 cuft contractor bags full)

This is one of the best videos I have seen on biochar. I have tons of bamboo around my land. It's called "damboo" here in the south. 🤗

[@michellestewart-h6i]

not sure if anyone has mentioned this or not, but be careful burning bamboo, it has pockets in it due to the area where each section is connected, I have seen these in the fire service when on wildfire calls explode due to water content in those pockets, it throws pieces of bamboo like shrapnel and causes some pretty bad injuries if you are near.

[@maunaowakea777]

There are some really good studies that show how biochar works well when incorporated into biodigester processes. It increases methane production and the higher heat helps impregnate the biochar with nutrients, the entire post-digestion slurry is then poured out onto a compost situation, allowing the water slurry and shift from anaerobic to aerated microorganism, finally, the massive carbon feed once added to soils massively spurs mycorrhizae production.

[@shantibants3949]

100% right about picking the material. bamboo is good because it's a grass but in a reveg area in Australia I like to use the natural wood that drops in the area - acacias are common because they do die off quick. It's not permennat compost it's one of the main ingredients in my growing media because it stops leeching of nitrogen and accelerates nutrient cycling because the difference between of the activated oxygen. My seed raising mix is 1 part coir, 1 part sand, 1 part bio char.

I enjoyed your video. I’m in the process of building a house & moving to a small piece of land in the Withlacoochee Forest, in S. Sumter County. Most of the lot was cleared of trees by the previous owner. My soil is only about 1’ deep then fine sand. I’m looking forward to putting lots of Bio Char, Tilapia poop, sawdust, wood chips & compost into my soil then growing lots of native food plants. I’ve only made some “rough” charcoal on the ground by burning fallen trees then smothering the fire after a while with dirt then water. Then covering it with a tarp to keep the rain off it. I sift it then mix the char with all sorts of organic stuff. The ash I mix with a soil acidifier & the sand in the fire pit to be used later. I’m also filtering the pond water with chunks of Char which should be a perfect filter then adding that filter material back to the soil. 😊

[@paulkroll7616]

David, How is the project going? Come on out to our local Lake County Permaculture meetings, 7PM first Tuesdays at Fort Jeppsen Ranch in Howey-In-The Hills. We have a great group of homesteaders sharing information every month. I'd enjoy meeting you and we can chat biochar.

[@davidmurley1863]

I’m still building the house. Foundations poured. Tilapia are eating about twice as much as they did on August 27th when I got them. About 3 weeks ago. No dead fish! I’m harvesting the sludge from the bottom of the pond and pouring it right on the few plants I’ve started in the ground. I’ll probably show up at your meeting in a few months after the house is finished. I’m using a big paint stirrer to break up the char in 5 gallon buckets in a solution of pond sludge, powdered egg shells, leaf litter, fish emulsion & washed, decomposed seaweed. I dilute it about 10-1 immediately after stirring to get the tiniest particles in solution then immediately pour it on the plants. I ain’t killed nothing yet 😊🤞🙏

Do you not have to crush it or chop it up into tiny pieces? Do you leave it in the chunks as it comes out of the fire?

[@paulkroll7616]

I do crush it up with the shovel some, but chunky is fine. There are pros and cons to crushing the biochar down to a small uniform size. Smaller pieces have higher surface area giving you extra holding capacity for nutrients with it's adsorptive properties. Larger pieces have higher water retention. I leave it the way it comes out of the kiln to maximize the water holding capacity. Our local soils are very sandy and could use the extra water. The char is very brittle, so running it over a 1/2" hardware cloth compost sieve will break it down quickly and leave you with a uniform size. Plus, I don't want to breathe the coal dust and I haven't seen any significant differences in plant growth trials. Thanks for your question.

Don't focus on how much, focus on designing an easy system to turn waste woody biomass from onsite or nearby into biochar and use all that you make. More is better. Be sure to run the biochar through a compost system before using it in the soil. There are biochar cookstoves or you can make it all winter long in a wood stove.

I bought a steel 55 gallon drum. The seller cut the top AND bottom for me. I had some old elm firewood (elm stinks when it burns so its not worth spit for a woodstove)I can fill it up and place a rock under the bottom to allow air.. I then build a fire, and fill it with firewood logs. Trying to stack it as tightly as possible. Once its burning well, I place the steel lid on the top and shovel dirt around the bottom edge to cut off the oxygen. I come back the next day and half of my drum is charcoal. Some might still be hot. I hose it down before I put it in 5 gallon buckets for use as blacksmithing fuel or biochar.

'Permanent compost'....mind blown! So, would we apply the charged biochar the same ways as we would use compost in the garden and containers? What would be the recommended first application ratio to "average" garden soil at the beginning of the growing season? And then....no more compost or worm castings? LOL. I thought I was just starting to get the hang of this composting cycle, and I have to go back to GO. But the bonfire looks like a fun activity, not so much in a Florida summer, tho. Thanks for all the info and material for thought.

[@TheUrbanHarvest]

I would add what you can as your able but you would never go straight char or anything. Maybe up to 1/4 max but you don't have to get there over night. Especially if your incorporating into your normal composting efforts. Its definitely hot but can easily be combined efforts with a hang out fire in the fall/winter. Composting and worm castings are both still fantastic amendments. And as you continue to add them to the garden the biochar will recharge of sorts. No need to stop your standard operating procedures.

[@fenrirgg]

Nah, you still need the compost and mulch to charge and feed the biochar and the soil, because we can't take from the soil indifinetly, something has to go back.

@@fenrirgg Since the biochar will provide lovely crannies for more micro residents, I guess the growing population has to be fed so they can in turn feed the plants. Makes sense.

Lump charcoal will work if you run it through a full 6 month composting process to give time for the fungi to eat up all the oils left by the incomplete pyrolysis.

Is the reason bamboo grows 6 times faster because the stems are hollow and they actually contain 6 times less actual biomass per metre of trunk length than solid wood trees?

[@martisbvk]

Bamboo is a grass. It grows like grass grows. Trees produce wood, bamboo produces a stem similar to a bush. Wood is made up of lignin, which is a very complex molecule and is difficult for the tree to make. Bamboo doesn’t contain much lignin.

[@Twobirdsbreakingfree]

@@martisbvk okay, so is the growth 6 times faster in terms of total biomass or 6 times faster just in terms of culm length?

Correct. And the recipe is not exact, but it is a great start. We are looking for nutrient and microbial diversity.

Biochar will only improve plant growth when it is in contact with the plant roots. Crush it small if you are going to surface spread the char so that worms and water infiltration can easily bring the biochar down into the soil. The best use is in potted plant starts. A one time tilling of the soil could get biochar mixed into native soil well. Shoot for 2% in large scale farm soils and 20% in amended garden soils. A little at a time.

I collect charcoal left over from camping fires and burn offs (mainly eucalypts, acacias etc), then wash off any ash and add to my compost. Is this good or not? Any comments gratefully received.

[@paulkroll7616]

I would continue to do it. Just be sure to compost it well.

Can we use coconut shells for making biochar?

[@paulkroll7616]

yes, you would want a retort type kiln for making biochar from coconut shells.

I live in a country with no garbage disposal so I burn all our garbage. What happens with the melted plastics if if is added to compost?

[@paulkroll7616]

Don't burn plastic. Don't buy plastic or things packaged in plastic. Burning plastic releases: -Dioxins & Furans: These are highly toxic and carcinogenic chemicals that can cause a range of health problems, including cancer, reproductive issues, and developmental disorders. -Polycyclic aromatic hydrocarbons (PAHs): These are known to cause cancer and can also cause respiratory problems and other health issues. -Benzene: This is a known carcinogen that can cause leukemia and other blood disorders.

Can ash from a pellet stove burning somehow be used to create biochar? I layer my pellet stove ash in the compost pile currently.

[@paulkroll7616]

No. The wood has burned the carbon in the wood pellets into carbon dioxide already. The ash will have potassium and some other minerals, but no carbon.

I think you can do it more productively when you use the fire to for cooking.

[@paulkroll7616]

When we build the ecovillage we will use a heat exchanger to capture the heat in water and store it for space heating tiny homes during winter.

Another popular KZbinr said to use the red bag Royal oak that is sold in stores, that' thats bio char,? Thoughts?

I've never used/seen it but a quick search seems like that would be the case.

Royal Oak is charcoal. We want to take the fire hotter and drive more of that syngas out of the wood and reform the carbon bonds. Royal Oak will not last 1000 years. But it might last 60. Experiment and try the Royal Oak pellet charcoal too.

[@roncatlin7271]

i use royal oak pellets in my compost. in my bin i add a layer of brown then a layer of green then a layer of activated pellets (pellets are soaked in worm tea with a touch of molasses or maple syrup for a week). i have 7 bins (20 gal trash cans with air holes) set up in succession that has been allowed to compost for 6 months. the temperature of the bin usually turns ambient during month 4 but it sometimes takes until month 5. i always have a bin ready to go and 1 working. biochar or not, there is absolutely no doubt this works and my (grow bag) garden couldn't be more productive plus i feel good about the material i am keeping out of the landfill.

[@TurnThePage7800]

Do you know if you burn clean mulch if you would get the same results?

[@TheUrbanHarvest]

You can technically but it is much more challenging to maintain the temps and add enough fuel for it to not ash.

[@t.dig.2040]

I use my seedy weeds, but dried cheat grass would be impossible to cook in a pit. So I use improvised retorts. I like being able to take a cool cooked can and just dump it into the compost and be done with it. No crushing or sifting.

[@paulkroll7616]

Moisture content is the big problem with burning woodchips. I will throw in a few buckets of chips during dry the end of the dry season, but if the chips are wet, the fire cools down and smokes. Bamboo is ideal and most homeowners are happy to give it away in exchange for maintaining the clump.

[@skitzochik]

compost is so much easier, food scraps is something we already throw away...no searching for stuff to burn. Some people live in areas where doing a burn is a huge fire hazard. He said its taxing on your body. Its just much easier to compost

[@paulkroll7616]

Adding only 10% biochar into your compost pile makes your compost last 300% longer in the soil. Biochar and compost work very well together.

[@RevLetaLee]

How do you produce biochar in an urban setting? We are not allowed to have any kind of fire in our urban setting. ?

[@paulkroll7616]

Google: TLUD Clean Cook Stove

[@barrysupernaw]

Do you plant right in the biochar or mix it in the garden soil?

[@paulkroll7616]

Mix into soil at about 3-5%. The best way to inoculate biochar is running it through a composting process. The plants will respond best when their roots are in contact with the biochar. I have one experimental garden bed mixed to 95% biochar and 5% worm castings and this garden bed has been growing peppers well, so don't feel like you can add too much biochar to your soil to damage it.

[@barrysupernaw]

@@paulkroll7616 good info, thanks

[@CriticalThinking101]

So if I have a weed tree I want to get rid of, I can just pour charcoal around the tree as mulch.

[@dfabella85]

Can you use charcoal from grocery shop.

[@TheUrbanHarvest]

There are a few brands that are pretty close make sure its actual charcoal wood with nothing added.

[@MartinGoblet-be]

Many thanks for this very instructive video. There is just a point I don't understand : what's the difference between goed charcoal I put in my compost and the bio-char ?

[@barneyrubble4827]

No difference if you're burning it correctly. Biochar implies a soil application, charcoal is a universal term.

[@MartinGoblet-be]

@@barneyrubble4827 Many thanks.

[@t.dig.2040]

Char is char, but once saturated with microbes, I am comfortable calling it biochar.

[@paulkroll7616]

Charcoal is made at a lower temp and will have residual hydrocarbons in the pores, (that give a charred flavor to your food). Biochar is heated to a higher temperature to remove all the hydrocarbons from the carbon structure.

[@klauskarpfen9039]

@@paulkroll7616 and you really believe that there are no unburnt or half-burnt pieces in a kiln?

[@canorth]

So you want to burn it anaerobically. So, I have a burn pit with good circulation and it’s not easily modified to not do that…. I’m wondering, I work with ceramics sometimes, if I make a closed ceramic container that I could fit in my Weber grill… I think that’d work?

[@TheUrbanHarvest]

I don't think so. The temps would get so hot that it could shatter. But I'm no clay worker...

[@t.dig.2040]

I have used a lot of old popcorn cans with a ring of holes punched through the lid and have even got as simple as a metal can with an open top flipped upside down. The closed chamber with a fire built around it works great. Just make sure the chamber is vented. Pressure is a bad thing when dealing with explosive gases.

What to do for those who live far from the rock mountains and do not have access to rock dust, where to get rock dust?

[@paulkroll7616]

Ask at a local stone yard. Decomposed granite is a material used for paver base and found across the US. A few 5 gallon buckets is enough for an entire garden.

[@peytonhenny4814]

So how many square feet of garden does 5 gal amend?

[@TheUrbanHarvest]

Its all relative... You can add up to 20% biochar of the overall volume of soil. But any amount especially 2-5% will make a tremendous difference.

Heavy metals are in wood and the substrate they grow in. There are heavy metals in regular woods ash.

[@tonyhidayat8925]

can Biochar from rice husk perform the same result?

[@t.dig.2040]

Yes, absolutely. Although it may be difficult to make in an open pit. I use a lot of the pulled weeds from the garden by packing an old popcorn tin (with a ring of holes punched through the lid) and then building the fire around the can. I like using fine materials in a retort because once done, I can add it directly to the compost with no crushing or sifting. The downside with retorts is that you're limited to small batches, whereas with the pits, one can make some volume.

[@paulkroll7616]

Yes, but the rice husk will more easily turn to ash in a flame cap kiln. I would use a retort style kiln if all I had to work with was rice husk.

If my soil is compost rich.Can I use the raw biochar directly onto it?

[@paulkroll7616]

No, compost the biochar first. The capacity of raw biochar to pull nutrients and microorganisms from existing soil is amazing. A biochar amendment is playing the long game, no need to slow down a garden crop just to add it quickly. Get it composting for 2 months and then get it down next to your root systems. And inoculate it with the most microbial diversity and mineral nutrient diversity available. Multiple types of compost, purchased inoculations, fish hydrolysate, sea weed extracts, moringa plant biostimulant, whatever you can find, add. If not, just a local backyard compost works well too.

@@paulkroll7616 How often should one keep adding the biochar to the soil?

[@paulkroll7616]

@@lillianmuite9241 It is so beneficial to compost piles, I would add it to every compost pile at about 5-10%. In your soil 5%. No need to go past that concentration. You could, and you would see water holding capacity improvements, but diminishing returns of all the other benefits. 5% in ground, 10% in raised beds, 20% in container gardens.

I’m in a prolonged drought. The lawn is gold, like straw. There’s a 30 foot ring of green grass. It’s an old burn pile.

Older cultures were far more observant. The historic documents about char all describe the same observation as yours. Things grew best where there were concentrated fires. Thanks for sharing.

[@Terrakis]

Wondering if you grind the biochar up at all - is it more efficient in smaller sand-like particles or are chunks ok?

[@TheUrbanHarvest]

Smaller pieces are ideal for most uses.

[@roncatlin7271]

sorry to but in here but smaller pieces are preferred but ground up may too fine. you don't want anything resembling ash.

[@barneyrubble4827]

Ash is very different in composition than biochar. These are microscopic bacteria it's housing so smaller is better tho I wouldn't go to fine powder either, that doesn't make it ash tho. Pea gravel size would be more efficient than large chunks but it will break down over time working the soil so some maybe walnut size pieces would be good too

[@paulkroll7616]

My philosophy: I want a variety of shapes and sizes. Diversity, diversity, diversity. In practice, I crush it when hot in the kiln with a shovel.
