A complete guide to soil microbiology.

The single most impactful thing a gardener can do is learn about how plants work. To do that, you must learn about the soil food web of life. I hope to cover this topic in detail in this video, but also keep you awake and entertained while doing so. This is just really important information to put into your gardening tool kit, because it will save you from making many mistakes - some of which can cost you decades.
This video represents years (literally) of reading books (including university textbooks), podcasts, research papers and digging that I have done. This isn't me talking here, this is me simply relaying the information I've learned in my own journey.
So much of this information seems like it's "book info" and not useful in the garden, but it's simply not true. If a soil test came back high in nitrates but low in ammonium, what FUNDAMENTAL THINGS would that tell you about your soil? After watching this video you will be able to answer that question with ease, and then take specific action to move the system and soil to where it needs to be.

[@TheWeedyGarden]

Would you say that LAB (being an anaerobic bacteria) would be bad for your soil (if added to your garden soil sparingly)? Would you say yes, they are a kind of “plant friendly’ anaerobic bacteria in that sense. Perhaps an ‘exception to the rule’, or would you say no, LAB are bad news and will create an anaerobic environment in your soil? Same question regarding bukashi, or “compashi’ as I call it. Short answer yes or no is fine Keith if you would be so kind. Really great SFW explaination btw 👍👍👍🙏🏻🤎🧙‍♂️

[@CanadianPermacultureLegacy]

This one is a really difficult question, and one that I'm not sure ANYBODY knows. For example, the Dr Ingham way of thinking is that the line in the sand is drawn between aerobic and anaerobic, meaning LAB is bad. However, there are techniques that use almost exclusively anaerobes, such as bokashi that you mention, but also Korean Natural Farming (Cho Han Kyu), Indigenous Microorganisms (which isn't necessarily anaerobes, but cannot preclude them), and most prominently the technique of Jadam (Youngsang Cho), which almost exclusively will breed anaerobes in the liquid fertilizers. The current thinking is that the breeding a natural fertilizer using anaerobes, is fine as long as the soil it is being applied to is well oxygenated (no-till gardens, or forest soils in heavy polycultures). You can place the anaerobic liquid, and within minutes the aerobic Microorganisms will outcompete the anaerobic ones. All that will be left is the nutrients in the liquid fertilizers and a culture of aerobic Microorganisms who eradicated the anaerobes trying to invade aerobic soils. So I think as long as your soils are healthy, applying anaerobic ferments like Jadam fertilizers or LAB like you made in one of your first videos, those are okay. However if your soils are damaged and compacted, you could cause major problems which may be difficult to reverse, as the anaerobes will now have "home field advantage". I hope that helps and isn't too confusing. It's a very complicated topic, and honestly I don't think humanity knows enough. Plants are VERY complicated. Here's another video of mine that explains just how little we know about plants kzbin.info/www/bejne/b3bco2aripeegJY, if you are interested in more. Thanks for the comment weedy!

[@TheWeedyGarden]

@@CanadianPermacultureLegacy thanks for your answer Keith. It is what I thought also, so it was nice with a confirmation. Thanx for the in depth answer. Much appreciated.

[@B01]

LAB and FPJ and those types of inputs are best used by people who know what the signs and symptoms of going anaerobic is. Dr. Ingham states that with caution they can be used successfully, but that she's seen plenty of instances where it went wrong (due to specifically those anaerobic disease causing organisms)

[@B01]

​​​​@@CanadianPermacultureLegacy ​​​​​She did mention it specifically, I'll try and find a link where she says with discretion it isn't bad, and how she says she generalizes when referring to anaerobic bad/aerobic good (I've watched a lot of her content and she's only mentioned that once I can remember). She emphasizes that this is an Intro-Intermediate mindset basically and when advanced enough (microscopy identification techniques down pat I'd imagine she means) then can incorporate those inputs which are anaerobic. So she doesn't seem to want to say anaerobic are good when 95% of the disease causers are anaerobic and can outcompete if not incorporated successfully by someone with the knowledge/background to do so. Most people she is addressing will not have such a knowledgeable background so it def makes sense why she'd be so steadfast with her definitions most of the time. You were basically spot on with your answer, and lined RIGHT UP with what she's actually said without knowing she said it hahah very possible it was one of her newest videos!!

[@DoseofScienceDoS]

To be very clear. In order for all nutrients to be absorbed they will need to alternate between an oxidating (dry) and reducing (wet) state. In order to reach the required reduction state you will need an anaerobic soil. If you haven’t put lab and yeast in your soil you will run the risk of salmonella, e. Coli, or other nasties overpopulating.

[@m.j.carlson8246]

Speaking as a trained microbiologist, they may not be your words per se, but your clear explanation shows your actual understanding of the subject. Especially aerobic vs anaerobic microbes. Well said, well done.

I've found only one local person with a wild permaculture property (he runs a nursery out of his tiny driveway) who talks non-stop soil/plants...that's part of why I'm here, searching for the rest of my tribe.

Yeah, it's the same thing everywhere. I can make a video or photo about unique "weeds" and their benefits, and get almost no "likes", but then the too posts are gardeners who pick carrots after 4 weeks and laugh about their "tiny cute carrot", and it gets thousands of votes. Kind of funny.

[@chachadodds5860]

I could've listened for another hour. Your videos are always informative and interesting, but this one is especially superb. I've read some of these references, and seen the original presentation on the chart in the thumbnail, so the concepts you talked about are familiar to me. But wow! You really brought it all together in a way that made even more sense, with several light bulbs going on, and the answers to a couple of questions I've had floating around in my head for quite awhile. Like the fact that plants don't need to be spaced out, if the soil is healthy and balanced. Plus, this video was punctuated with some very funny moments. In essence, you have a knack for digesting the academics, and feeding it to us in a way that not only makes sense to the average gardener interested in doing their part to rebuild the earth's permaculture, but you also give us practical ways to apply the principles to our little corner of the planet. I'm down in New Mexico, located in a mountainous region of high desert, with dead dirt. I know that sounds like an oxymoron, but New Mexico, is quite unique in its climate and terrain. Of all the many places I've lived, and gardened, this has been the most challenging, and I've spent the months, just working on providing what the ground needs to begin the journey toward health and vitality. Yet, I watch all of your videos. Not just because you are enjoyable to listen to, but because I always learn something from you; even though you're in Canada. Thank you, for everything you do, and all that you share. You are much appreciated.

@@chachadodds5860 Agreed! I'm down in the south of Africa and in a drought-prone, coastal Mediterranean environment, so couldn't be further from the Canadian climate - but this is my go-to channel for the right mix of information and inspiration. I do have moments of acre-envy and water-envy - but am learning to work with what I've got. Which is, admittedly, a lot more than desert! Having said that, I think the challenge of working in a desert/hyper-dry environment must be one of the most exhilarating of all - if approached from a permaculture viewpoint. It is the holy grail of restorative and regenerative projects. More people need to understand and promote the fundamentals of soil health - it is one of our most vital tools in helping stabilise our world right now.

Awesome! Glad to hear it, thanks for the feedback. This one took a while to put together for sure. I never know how "sciencey" people want the videos - actually I have a pretty good idea and the answer (for the average viewer) is not very sciencey at all. So a video like this comes at a risk that you put a hundred hours into it and it gets 1k views, no comments and even worse, people think "this channel isn't fun anymore" and unsub. It sounds silly but that's just the reality of hoping to grow a channel. The goal of this channel also isn't to solve any scientific questions regarding soil science. The goal is and always will be to inspire new people to take up gardening and planting more trees. I'm hoping that through this platform I can do more good on this planet by creating some kind of snowball effect off of what I did on my land - and that when I'm in my deathbed I can look back on my life and know I did as much as I could for my kids and the planet they will inherit. So when I say I appreciate that feedback, I really do. Like I REALLY do, because it tells me that all this work I'm putting in is worth it in some small way at least.

Thanks! On your "PS".... Treat everything that I'm saying with the "drunk guy at a bar" methodology. I.e. if saw a drunk guy at a bar standing on a table ranting and raving about something.... except... it actually sounded pretty well thought out. You know, he's raving about some geo-political issue or something... but he's making a whole lot of sense. Treat me like that guy. You should be thinking... hmmm... that all sounds interesting... buuuuuut I think I'll verify the facts in the morning before I make any life decisions on what he's saying. I think that's a good overall attitude to have with any youtube information. On other channels and even on mine. So pick up some of these books, give them a read, pick up more books, give those a read, and get as much information as you can get before you decide something is true or not. Then never close your mind to the possibility that all those sources may be partially correct, but may not have the complete picture, and that science can always be improved on. Very little science is fully settled. And that's especially true in an area where breakthroughs are constantly occurring, such as soil microbiology. We're just starting to realize how important it all is, but that also means that a lot of what we consider to be fact is going to change as we learn more and get better a better resolution on the image we think we have.

There is some crazy stuff that happens with certain plants when you get down to that level. There are some plants (you know the ones who grow on rocks and you are looking at them thinking... what the heck is that plant eating, there's no soil there). The plants have evolved a way to make the epithelial layer of their roots permeable to bacteria. The bacteria literally walk into the plant root but cannot get out, and the plant literally absorbs them. It's like, fully blown alien level of weirdness down in the wild wild west of microscopic soil life.

Amazing video and absolutely fascinating concepts. I’m a big fan of building soil and I was wonder how can we take growing food to the next level. It’ll be so cool to figure out what plants to plant that will drive the population of certain soil microbes. Do do this I think we need to figure out the root exudates carbohydrate structures that the plant produces and the corresponding microbes that feed on them. It’s definitely a complex relationship but we can group the type carbs/microbes to get a better idea of what plants to plant for driving certain soil biology.

[@CanadianPermacultureLegacy]

Just as an example of how complex this is... the USDA lists roughly 44 nutrients that plants need, 17 of which they consider "essential". Those are just the atoms though... Sulphur, phosphate, iodine, etc. Well take chlorine (extremely toxic) join it to sodium (extremely reactive) and they form together to make table salt which we can eat (relatively) safely. All these atoms form complex compounds. Right now, there are research groups trying to identify and catalogue what various COMPOUNDS do for the plant (and then potentially be useful for human health) and they are cataloguing literally MILLIONS of varieties of compounds that a plant carries around in it. An analogy to help explain this, is imagine an alien being comes down and tries to research and understand our language. It can't understand anything we are saying, but it has figured out 9 of our 26 letters in the alphabet. And it thinks, as long as I give these organisms these 9 letters, then they have everything they need to write a book. So give them another few decades and now they know that we put those letters together to make words, and they've figured out 1200 of our words that we use. They now think if they give us these words, we can write a book. But there are 171,146 words in the english language. Now think about how many different possible sentences we can make with those. How we can convey emotion and passion and information transfer with these "letters". They may understand the shape of the letter, but they don't understand the nuance of language. They don't understand how that conveys into emotion. Now consider that only some of us use this language, and many of us use completely other languages, even unspoken ones through our body movements and facial expressions. But these aliens think they have us all figured out, they think they know what we need to exist, so they sprinkle letters on us, dump water on us and think we'll grow. And we can kind of struggle out a meager existance based on this mess, but we'd really just like them to leave us alone and go back to their home planet. That's basically where we are with soil science right now. We know the rough shape of less than a percent of their numbers. Another example, root exudates. People think of root exudates as "a root exudate". However there are hundreds of thousands of different root exudates that the plant has access to in it's tool kit, and it selects which ones to produce based on the soil environment at the time. This is an ENDLESS avenue where we could research for the next ten thousand years and not uncover even a fraction of a single percent of what's going on in the soil. We think we're this super smart species, but when it comes to chemistry, the true master chemists on this planet are the plants. We may actually never understand what they are doing. I guess that's what you get when you have billions of years of evolution baked into an organism that is so dramatically functionally different than we are. Hmmm, maybe this would be an interesting video...

Amazing synchronicity! This crossed my desk when I returned from a conversation with my builder about the completely compressed soil his giant machines made all around the wonderful house he built for me. I was tempted to have him remove 4" of hard packed clay (as welcoming as concrete) and replace it with top soil. My first instinct had been to cover it with compost and then wood chips, spray with compost tea, and leave it over fall and winter (it's now nearly August in Zone 5), but I had abandoned the idea. I am SO GLAD you've given me the fortitude to try it that way. Can't thank you enough. Best video EVER!

[@ChristopherPisz]

I've had glorious success just letting kitchen scraps, meat, milk, weeds, cheese, fat, and anything organic at all, rot in a 5 gallon bucket with a lid, and then diluting the result with water and feeding it to my plants. Side by side tests for quite awhile have shown me that this makes a huge difference in my soil. I don't buy that anaerobic is "sooo bad!", and I constantly have to say this anytime Miss Ingraham has had her ugly influence on anyone. She is completely over zealous about her fear of anaerobes. Sure, if you see anaerobes in your compost, you aren't turning it enough. But plenty of people use anaerobic processes to feed the soil, and I've yet to see any evidence at all of any detrimental effect whatsoever. It's natural. When you put a rotting carcass 6 feet into the ground, do you think those are aerobic bacteria breaking that down and feeding plants? nope. Aerobic bacteria are only on the top few inches. I also suspect the dead carcasses of anaerobes are actually feeding the aerobic bacteria in the layer of soil where there is oxygen. There are also bacteria that can survive in both environments. We also haven't identified and don't know anything about 98% of the bacteria out in the world. I'd love to have soil that needs nothing, but there was no life in my lot at all when I started. Just 80% calcium carbonate in heavy clay, with less than 1ppb of nitrogen. Now, after spreading "rot water" and wood chips, I've got plants thriving in ways I never dreamed they could. When I get my next property, Ill will likely kickstart things in the same way and use it less once plants can actually grow and feed themselves their own organic matter.

[@Horse237]

Look up Bokashi which is a Japanese technique and Jadam which is Korean. They are both anaerobic. When the PH gets to neutral, you can compost it. I suggest using worm bins to make vermicast. Worms turn coffee grounds into easily absorbable amino acids.

@@James-ol2fr I can appreciate that, but she has achieved a status where she is the definitive source of soil life in many people's eyes and many people accept what she says without question, so I try to raise those questions for public view.

Sooo good, thanks for putting this together. Question: when starting a small garden for vegetables, weeds might cover what you're planting. In that case your recommendation is to just cut them so they let sunlight get to your veggies, instead of pulling them out whole?

[@bethreiners5568]

I KNEW those weeds were there for a reason! I told my family if they’re not interfering with our garden plants, leave them. There’s a reason they are there. We started Mittleider garden fertilizer halfway thru this season, and will add gypsum/calcium to the soil at the beginning next year. This video really explains everything so well. My husband is a firm believer in tilling though. It’ll take a while for his “former farm guy” persona to change his stance on that.

[@CanadianPermacultureLegacy]

Yeah it's much harder to deprogram someone than teach a new person! For the weeds, exactly (!!) even the specific plants which germinate (I.e. which weed exactly) can tell you something about the soil. Each year, it's a different set of weeds that have germinated in my wild areas here. First year it was thistles everywhere. Second year it was tons of ragweed. Third year it was lambs quarters. It's been a mix of various plants this year, wild sweet Williams, corepsis, so many different ones. The plants perform specific functions, and require specific circumstances to germinate. Our soils have tons of dormant seed just waiting to germinate, and each one wants something different, and does something different to the soil. People said I shouldn't sow amaranth because they will be here forever. I sowed them in year 3, and 3 years later we have no amaranth, but I know there are thousands and millions of seeds here (anyone who knows amaranth knows what I mean, those things make SEED). But they won't germinate because my soils aren't depleted anymore. I bet if I dug another swale and disturbed the soil and volatized all the carbon I would get Amaranth germinating the next week.

That's exactly the response I was hoping for! So many people see science as this barrier they cannot cross. I see it as door-opening, idea spawning, and this endless source of inspiration. Learn something new, and bam, you now think of all these new projects to try to use that information and leverage it into either doing things better, or reducing work that you do now which was actually hurting your progress (like weeding, tilling, etc).

The size of the stones isn't the only thing that makes up the difference in soil particles. The sand particles tend to be roundish which when put together is why water drains through so quickly. Clay, on the other hand, is more brick shaped, which is why water cannot permeate it as well.

[@mrwess1927]

So not only size of the particles but also the shapes of each particles should be taken into consideration.

Frogs are the "canary in the coal mine". They are very fragile, and are one of the first species to die off if there is a problem with toxins. Conversely, if you have a lot of frogs, its a good sign that you are doing something right. Great comment!

[@annikasyren3696]

Thanks so much! I watched til the end, and will watch again. It’s a lot to digest. Regarding bokashi, blending the fermented bokashi with soil and leaving it for a couple of weeks before putting it in the garden, isn’t that sufficient to make it aerobic?

[@CanadianPermacultureLegacy]

It is, in terms of the microbiology, but all the byproducts are still there and the soil will also soak them all up. Some of them are very stable and will stay in your soil a really long time. Volatile siloxanes are a good example of this, which is basically volatized sillica. Hydrogen sulphide is a particularly nasty byproduct that will then contaminate your soils for a very long time. Acetic Acid (vinegar) is produced in a substantial quantity. Vinegar is often used as a weed killer because it kills plants. So although the soil microbiology will transition away from anaerobes over time, all those byproducts will get soaked up by the soil, and then put into the garden. The best way to convert even the byproducts is to apply oxygen to the liquid batch for as long as possible before it ever touches the garden. Another thing that can help is to mix biochar in, because the biochar will lock up many of these volatile compounds and make them inert (similarly to how toxic chlorine is bound up in salt (NaCl) and relatively safe). The only tricky part is that is the biochar itself must really be made properly so that all the volatile oils in the wood are burned off and recombusted.

[@CanadianPermacultureLegacy]

It is, but it's also a sign that the pile has gone cold. That's okay if the pile is at least a month old or so. But if the pile is new, it could be an indicator that you are carbon (brown) heavy and you should add some green (grass clippings for example), turn it and water it, and get it fired up again. There is nothing wrong with a slow worm driven compost pile though. It just takes longer, but it may infact come out more nutrient rich.
