Evaluation of Biochar for Agricultural Soil Management in California

[@randomperson1157]

The benefit of inoculation is unfortunately not addressed in this otherwise excellent research. The closest it comes is at 26:25 where she discusses mixing it with compost, with little result. Later it's discussed that they tried applying dry biochar, which leads me to believe that it would not have been first inoculated, which is a critical step in adding microbial benefits. Without first charging the medium, it will have the opposite effect and pull from the soil.

[@snailspace1269]

I have to agree. If not inoculated it's just charcoal.

[@denveready3486]

I also agree, un charged or un inoculated bio char is just raw charcoal, and I can see this having a direct impact on the dust particles in the dust test results, also the nut shells used as a medium for bio char has me scratching my head alittle

[@Davidmc23]

Yes and not at all. Uncultured biochar will culture in the soil but there will be a temporary drop in nutrients but it'll come back after the char has been colonized.

[@richardlee3993]

I wonder if they are activating the bio-char by shocking it while still hot with water? Also it is recommended to charge it with nutrients before applying it to the ground. If you do not pre-charge it it can leach nutrients out of the environment. In terms of economic viability, the cost can be negated by large scale production, which could include generating electricity. Also, I'm interested more in using livestock waste (like cow manure) as feed stock.

[@gabrielglouw3589]

Is it just me or was this done with biochar that wasn’t inoculated properly? It sounds like inoculating the biochar was an afterthought and not a priority. I would like to see this study repeated with actually good biochar.

Were each of the biochars inoculated differently? How long were they inoculated for? Was synthetic nutrients and pesticides used to calculate the yields? It's sad that crop yield is the main concern. We need to be studying the difference in nutritional values between food grown with and without inoculated biochar (organicly).

[@robertsmyk4102]

You did not discuss charging biochar to make it an effective soil nutrient. Your mention of "biochar" should be replaced by the word "charcoal". The photos of "biochar" dust is actually charcoal dust. Nobody should apply dry charcoal to the farm soil. One reason to add charcoal to soil is to replace sand if sand is not available to mix with clay so as to improve drainage. Eventually the charcoal would accumulate water and nutrients and be able to nurture fungi and other soil organisms.

[@anxiousbeachbums]

Ha! Today I ventured into a California wildfire burn area (east of Placerville) and collected about 25-30 lbs. of "char" to bring home and inoculate into "biochar". This evening, I stumbled onto this (not so positive) video. Yikes.....!!!!! Very interesting/Very informational. This char "should" be clean.......merely USFS pine/fir trees and, after inoculation, I'll only be applying to two 10 x 10 plots in a community garden. I also understand it may take 2-3 yrs. to receive any increase in yield. That's part of the fun of recreational farming.........experimenting with new and yet-untried things.

[@Flumstead]

The use of biochar in aquatic systems is less well studied, but the benefits are enormous for water quality. It's also a good way to use the larger pieces of biochar and has a higher value. So don't crush your biochar, which should also help to reduce the char dust problem.

[@koltoncrane3099]

From what Ive seen from different videos and people doing tests to measure absorption rates of biochar biochar varies by how its made. If you want a larger piece of biochar or charcoal that's fine, but that's probably going to mean that it was produced at a lower temperature in a barrel or machine or something or in a mound and smoldered. That charcoal is large and good to cook with, but its absorption sucks. It's okay, but making charcoal at higher temperatures in an open burn pit the study or experiment i say proved there was a huge increase in the absorption ability of that charcoal. Better charcoal or that's better at absorption crumbles easier. The dust problem really doesn't matter once its in soil. If you're in farming why wouldn't you want a charcoal that has better absorption rates? Most soil and dirt can be a dust problem. That's why you mulch and compost and give it time to settle. Maybe aquatic systems are way different and you don't need great absorption from your charcoal.

Unfortunately it seems that much of the research cited is from agricultural areas where soil was I assume depleted of natural soil microbe diversity which is becoming apparent as a major shortcoming in our agriculture system. It will be interesting to see how studies over the long term and specifically addressing soil microbiological diversity turn out. I am interested in results from combining Jadam Organic Farming or Korean Natural Farming techniques with biochar if anyone knows of such trials or information?

[@ttmventures]

Very informative on how charcoal affects the soils in your specific region, but ultimately this is a wasted trip if you're here for Biochar results, which is inoculated with nutrients and microbiology before it is placed into the soil. Placing charcoal into your soil obviously can help you manipulate the structure, water retention, electrical conductivity, etc. However in the first years, this charcoal will be stripping the existing soil of nutrients, before the microorganisms are able to colonize the enormous surface area, utilize those nutrients, and release bioavailable nutrients for the plants. It may take decades even to begin to have a noticeable difference to yields. Simply put. It's a sponge. Fill it with goodness before putting it into the ground and you get results. Put the dry sponge in the ground, it'll degrade it first, before eventually giving results down the line once it is saturated with a healthy microbiome (probably longer than 4 years). Regarding unwanted dust, simply saturate your Biochar to out the fire, and collect and store damp/wet.

I am doing it again this year, I then shovel it out carefully to avoid stones as I wet it again and run it thru a troy built wood chipper, I do about 3-4 burns, chips a year, then run the sugar cane thru the chipper I grow as a visual blocking hedge, put in alfalfa pellets, composts, hen barn cleanings aka poop, and whatever garden wastes we have accumulated over the season, then dig out that pit, spread start over.

The Dutch when they owned New York City back in the day the witnessed each fall the natives burned the forest. It wasn't thick and dense, but open and taken care of. Today in the western US like 9 billion cubic board feet or something cant remember, or millions of pine trees are dead because of the beetle.

Where in the vid does she say they did not charge the charcoal? I’m only half way through at this moment… but, yes, if they did not use char that had been seeping in a compost with ‘everything in it’ for at least two or three months, then it was a waste of time, as most scientific research ends up being used to suppress progress … she mentioned 2% by weight … the recommendation is to use 5% min from what I gather, but that’s volume not weight. And no more than 10% volume is needed. Also, if they are irrigating with salty water & fertilizers, the bio char loses effectiveness, essentially. While some lab created synthetic type fertilizers may be ok, if they add sodium or other factors, the benefits of the char are greatly diminished or canceled out. So those should be used minimally and tap water should be allowed to gas off chlorine or vit c powder (& ?) can be added to neutralize the chloramine in tap water. This is ideal for small farms & backyard growers… I can see great challenges for getting large operations to begin utilizing this. However, it appears to be possible, it’s just that there isn’t a magic bullet, adding bio char into large ag soils seems best done little by little over time, focusing on utilizing resources from the facility itself. I think it’s very doable.

Yeild impact is an economic capture sure. But what about flavor impact yield health impact from possible improved cations in the soil? TBD I am sure, but thinking about it from a gardeners aspect when competing on those aspects against others.

[@philortiz7519]

I'm absolutely sure native Amazonian took their char to a lab to see its best suited to qualities. The lab report must have been amazing. It's char. Any Carbon baked under heat without oxygen leaving hand crushable pure carbon is char. It works, Any and all. It works for any soil, for any place, for many reasons no lab report or study on its qualities. If its char it works. Open flame cap works just fine for lawn garden , amazing in fact. Enhanced, lactobacillus, fish hydrolysate, compost tead up and charged with this, words can't describe the results. It works. Everywhere you put it, the soil does better in most any and every way. Make, charge it add it to soil. The microbiology just seems to explode awake.

[@MichaelFingland]

No wonder it didn’t work. She only used 2% as a ratio of biochar to soil. I suspect the Char wasn’t activated or activated well as there are hundreds of case studies on KZbin showing material improvements.

[@dertythegrower]

I super appreciate this. More study and research please, I subscribed.

[@Elfunko99x]

I am so happy i downloaded this video to watch at 👷. This was incredibly educational and I look forward to trying the website to see what properties there may be in my locally affordable inputs for biochar. And the pm100 information was eye opening, than you! 👍👋

WOULD LIKE TO APPLY BIOCHAR INTO OUR FARM AFTER THE ACACIA TREE CUTTING TO MAKE WAY FOR RAMBUTHAN SAPLONGS

[@TheRainHarvester]

I use poly lining in my planting beds to avoid water loss (no drainage). Will biochar accumulate anything bad in such an environment? (Ex salt buildup)

[@applasamysubbharao2578]

Great Presentation. Very Objective Focused....Thank you very much...

[@padredemishijos12]

Is activated carbon from a distillery's filtration system useable as biochar?

[@gantz4u]

Yes. It should just be biochar from wood. The only concern is some very small chance its made from petroleum pitch. This should still be just bio char, since all of the volatiles are extracted but, if its petroleum pitch, youre playing in the unknown area using it as biochar. It should just be clean biochar if its used in the human consumption area.

[@kade426]

Being used as filtration means it will likely be loaded with things you may not want in the soil. Likewise charcoal from aquarium filters will be rich in nitrates from the fish but depending on the water source it may contain heavy metals.

[@padredemishijos12]

@@gantz4u The best activated charcoal for alcohol filtration is from coconut shells.

[@gantz4u]

@@padredemishijos12 Good to know. Makes sense since the structure of the charcoal product would aid in filtration.

[@craigrmeyer]

This is some proper and helpful information. Thank you.

[@CarbonConscious]

Those percentages at 6:00 into the video, is that by weight? And why don't they add up to 100%?

[@jonni2317]

the missing percentages is probably due to waste and loss they are burning stuff so even in the gasifier they are going to lose some product

Conclusion? Is biochar the same thing that's made when coal is turned into coke? If so, the thing to do is piggyback off coke production and import it to the fields that need it by the ton. (Thanks in advance: please refrain from the "carbon neutral" arguments against using coke for agricultural biochar. There's no such thing as anthropogenic climate change (see the work of Henrik Svensmark and the cosmic-ray control of climate.)

[@shexdensmore]

Without a complex and wide range of different types of charcoal used in the process, these numbers will skew the potential.

[@constantinaolstedt]

So much great information. Thankyou from Stockholm Sweden

I have a home garden in TN with very heavy clay and I'm trying bio char to help with soil compaction. I am also wondering if UCCE is doing any field test outsde of CA.

[@jamesvandamme7786]

I have the same problem in NY. Soil health is a solution to compaction. Use permanent paths; mine are like concrete but my beds are full of worm holes. I've put compost in them for 40 years but it degrades in a few years. I'm hoping biochar will hold the nutrients better, plus supercharge the fungus.

[@raphaelgaillard5335]

interesting thanks but isn't biochar, by his microporosity a simple habitat for microbacterial life, life that will improve your soil quality (aeration nutrients and so health) not a magic fertiliser, no habitat no life poor soil, and bad/mean bacteria that no one want in his soil!? enjoy your garden and keep it healthy as it can be!

[@SimonHaestoe]

12 ph biochar sounds legit LOL. thanks for at least telling us that was what you used. But practically noone will make their biochar out of almond shells - hopefully, as almond production is hell on earth for ecosystems and water usage - and why even conduct this kind of trial when you began by saying sadly almost no field trials are being done... A lot of this makes no sense whatsoever.

[@FelonyVideos]

It is good to see some quality field research. This is actually useful progress. I just wish scientists would lay off the whole "CO2 is a greenhouse gas" BS. Anyone who can read a spectral absorption graph knows better (which I suspect you all can and do). The planet needs more CO2, not less. We will be fine up to 4000 ppm.

[@michelbisson6645]

don t need to make syngas,,,,,if not needed..

[@kevinaschim8475]

Excellent presentation. There is really no compelling case for Biochar as there is concern about PAH, yield increases are unlikely, economics are unconfirmed but likely negative and the number of variables make it difficult to even justify niche applications. Disappointing but valuable research formation. Thank you

[@davidconnors7010]

First off you never mentioned how much biochar % you put in the soil second you never soaked it in water for two or more days otherwise you wouldn’t of any dust issues. You also never mentioned that you

[@lmvcnn]

32:45 Aren't harmful chemical compound breaks down completely under high temperature such as fire when making the char?

[@bartroberts1514]

This is really great, and the studies confirm beliefs about movement of water in some soils treated with biochar. Was there any indication that biochar might host soil microbes that could explain differences in crop development and/or nitrogen fixation?

[@ahowl7mx]

The biochar was precharged for 48 hours??? Isn't it supposed to be 3 months?? LOL no wonder there's no real results. I'm using 100% biochar as potting soil, but its been in my fishtank as a filter for 3 months. Also don't grind the biochar into powder, the smaller the biochar the less water it holds.

[@ziggybender9125]

One thing I'd like to point out is, it's a bit known that certain materials don't make good biochar. Hard woods tend to make the best stuff, I personally have been making it from Lychee wood.

[@kenyonbissett3512]

Sounds like a SARE study for a farmer.

[@michelbisson6645]

except to manage drought biochar in itself doest mean a lot if not inoculate properly, we need to rebuilt soil biology, other wise for me it is a complete lost of time...and money, we spent most of last century to deplete our soil, poison it destroy it, it will not be revived in one year, and for sure not with mineral fertilizer..that is for sure...

[@JustTheBasicsJS]

It’s not charcoal-like ...it is charcoal. It’s literally the same as activated charcoal supplement.

[@michaellinnebur7694]

You better hire a bunch of gay anti food pro buggy people stop us from using biocharge it just sounds so bad

Making biochar geographically separated from its source is typical bean-counter idiocy... Try again.
