Good presentation on soil in general

I would not spread biochar regardless of beeing loaded/unloaded or dry/wet. The only form is as part of compost. This should negate the dust problem also.

Planting my first cover crop after only covering my raised beds with compost for the last 4 years. This video really gives me confidence that combining cover croppung and adding compost will make my great soil even better. Thank you!!!

Can you simulate properties of Biochar in Soil through decomposition of green manure or deposit soil carbon, brought out from outside. Sum total effect should help microbes do nutrient cycling and manage carbon to Nitrogen and balance fungal to Bacteria ratio

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.

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.

Very useful information. Thanks.

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.)

From what i inderstand, biochar maitain those propreties, wich mean u don't need to add ferteliser/composte every year

Bio char fertiliser land use change carbon capture storage and food and feed production energy

The terra preta results stand for themselves over hundreds of years. You are doing something wrong, not the rest of the world.

Gives solid reasons on why multiple plants should be grown, why cover crops work, and why so many natural and permaculture with less tillage show good results.

If I rotate graze my animals how can I get them to eat bio-char so they can poop it as they graze?

Excellent research.

Biochar is best thought of as a permanent compost. Biochar stays forever but compost needs to be added over and over.

This guys classes must have been torture…

Thank you. Where can I find the Part 1 of this series?

1: you mentioned walnut shell biochar. what effect does charring have on walnut toxicity? 2: best practice is to do a few things to the char. 1: use a hardwood. 2: make it pebble sized about 1-2cm. (dust is minimal) 3: don't use pulverized or powered char! too big is also not effective. 4: activate/inoculate it with organic fertilizer or nutrient tea AND Mycorrhizal Fungi. (dry char will leach nutes FROM the soil if it's bare/dry. and 5: apply damp! no dust and less damage in transit and dispersal.

Why can’t you use bark chips?

Ucce. love itt. very fantastic edition! farewell. 👍

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.

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.

Its my understanding that the biochar needs to be "charged" using many different amendments. While you can simply add it to compost or add it to mineral fertilizers you also need to soak it for quite some time. Im currently charging a batch that will take 3-6 months to be ready. Its soaking in compost tea, molasses, fermented plant juice, oriental herbal nutrient, and many trace mineral salts. I dont want to stand in denial to the results showing no yield increase in certain cases but I cant help but feel, based on her explanation of the processes, that the research team may have not made properly chargef batches to work with. I hope that this research continues and I hope that the scientists are consulting with experienced biochar using gardeners.

Biochar infused/inoculated with bio-complete compost extract. Have she (Dani & team) tried this? Because not all compost is the same.

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.

Tilling increases soil erosion and therefore it's obvious that biochar would also end up above ground and contribute to dust in the air. If you don't till, guess what, biochar will stay in the soil.

biochar need to be inoculated appropriately, mainly biochar is just a sponge not a fertisiser, it help for water and absorb then release what has been inoiculated, you need stong biology in biochar, in europe they had special yield with micronised biochar....

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

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

Nice information ..thanks for sharing.

This is so interesting! I wonder where I might get my hands on these substrates in bulk?

curious what was said about bind weed in the questions section

🤤 P r o m o s m

Earthway seeder: "not very precise". Let me tell you what that means.... As I look out at my 4 rows of sweet corn in my garden I see gaps of ten feet in the rows where this "not precise" seeder failed me. When I actually planted Okra, the seed would lodge on the back of the seed plate and jam the seeder. Save your money and buy something better or just plant by hand.

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?

Where can you buy

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

Thank You ... as a Chemist and a Hobby Farmer I was very skeptical about this product. I know that there is a lot of guruism around many of these permaculture techniques and they really lead people down the wrong path. However its always good to examine any claim like this and not just dismiss it without testing. Honestly i think it really comes down to clueless people seeing dark soil and believing its better and not understanding what they're seeing.

The troubling thing about the UCD study is that adding chemical fertilizers would kill off many mycorrhiza and bacteria so any benefit of providing a “condo for microbes” is defeated by destroying the very microbes that it’s useful for. That seems crazy and explains why no beneficial results could be seen. Furthermore, Biochar that isn’t charged or inoculated would absorb nutrients out of the soil just like activated charcoal would. Although I’ve read that longer term raw Biochar can see better results if chemical fertilizers are avoided. That makes sense in that the condo for microbes would become populated by microbes over time. Another issue is that annuals benefit more from bacterial inoculation and perennials benefit more from fungal hyphae like mycorrhizae. The chemical fertilizers destroy the mycorrhizae…

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.

brilliant presentation! thank you

I’m new to this, but it appears that the studies are more aimed at augmenting traditional agricultural practices in using mineral fertilizers right? Several theories that I’m personally interested in. Adding raw Biochar to soil is more detrimental than good because charcoal absorbs nutrients rather than providing them. The studies here see a big benefit in water retention in lighter soils. The biggest potential benefits appear to be : Using Biochar to deliver beneficial nutrients to the plant roots. Using Biochar as a structure/matrix to encourage beneficial fungi like mycorrhiza. Mycorrhiza holds great benefit and most agricultural land is low in mycorrhiza because chemical fertilizers kill mycorrhiza. This would seem to be the avenue of greatest potential. I strongly suspect that the huge benefit demonstrated in the Amazon is largely from beneficial fungi and bacteria that Biochar encourages. It would seem that the greatest benefit from biochar is to optimally “charge” or “activate” it before application. This crucial step appears to be only basically addressed with experimenting with composting. RUclips is full of differing videos on ways to activate the Biochar. There is a bewildering array of activations such as: Manures, putting Biochar on the bottom of a chicken coop. Adding various manures in various stages of composting. Adding urine as a fertilizer Rock dusts like Greensand, Azomite (volcanic ash with lots of trace elements). Kelp meal or extracts Various mycorrhiza and bacteria Actively aerated compost tea. (There’s a zillion ways to brew that). Compost Various minerals Foods to encourage fungal growth like stale flours, molasses, sugars, etc. Worm leachate and worm castings Etc. The activation process seems to be the greater potential benefit. But there are so many variables to test! Since this generally requires significant time for this process step it’s a challenge for agriculture at scale and seems to be utilized more in regenerative agriculture and in soil remediation efforts. Those initiatives are aimed at promoting the microbes and organic materials and tends to utilize more permaculture principles like no-till and an opposition to chemical fertilizers. The current geopolitical situation is severely curtailing the availability of chemical fertilizers which has huge catastrophic implications to world famine, so fungal inoculation of soils with Biochar is more important now than in the past.

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...

Good presentation, but nothing about ORGANIC nutrient management. Would have been helpful to have some perspectives from organic inputs as they work much slower and are typically available in smaller quantities.
