David’s research in #soil microbial community structure and function has opened a window for viewing the interdependence between #plants and soil microbes. Rebuilding a soil’s microbial community population, structure, #diversity, and #biological functionality will also provide a robust and practical mechanism to begin reducing atmospheric CO2 within a #regenerative #agricultural system.
David and his wife, Hui-Chun Su Johnson, will also talk about the construction, filling, and management of the Johnson-Su static pile #composting #bioreactor.

Hello from Italy. Thank you Mr. Berns for all your videos. I just wanted to give a shout out to the women in customer service that helped me get my small order out the door to my Mom's house in California. Doris and the Wisconsin Badger (poor girl surrounded by Huskers) were both super helpful. They went the extra mile and in a few minutes resolved the problem. My Dad was born in Schuyler Nebraska so it is real nice sending business to his home state.

I have a huge, 20x20x 6High compost pile, I have manure, chips, prunings, alfalfa pellets plant waste. I put a heavy 1/2" poly drip line on the soil base. And another on on the top under about 6" of pile, the top one gets watered via a timer,the bottom one is fed from my shop air compressor, and in the summer via a solar powered small portable 12V compressor, the solar is usually done after a summers run, but only costs less than $50. About 2 bags of fert, cheap. Panel and battery last for life of normal. I have 2 of these liles, always one on the go, when I terminate I switch the water, air source. My pile is usually full of worms, as is my soils that the compost gets spread to.

When looking at the extract under microscope how many fungal spores and diversity do you need to see per field of view? At a given power

I'm curious about the texture of the compost. Dr. Johnson mentions it having the consistency of clay and there is video of someone working it in their hand. What gives it such malleability? Why is it clay-like? Will the product be the same texture regardless of the original material being used?

For the talking point on gardener scale, Diego Footer has many videos on creating a smaller scale bio-reactor with a 50 gallon trashcan.

Most corn both non gmo and gmo seed comes treated with fungicide. Would you still recommend compost extract in furrow on fungicide treated seed?

Main problem with this approach is that the micro-organisms composition, their ratio to one another depends on your climate and geology. So it does not make sense to import this product, seeing how easy it is to make it on-site. You will then select the already-present and adapted organisms present in your soil.

NPK does not correlate to plant performance, nor does organic matter. the F:B ratio does. as Dr. Hui-Chun Su says the OM doesn't matter when there is no soil life. biological functional carbon - what Dr. Christine Jones emphasizes - the liquid carbon pathway - plants performing well exudes functional carbon - functional cos it promotes plant performance. this was one of the most astounding of the results of Dr. David C. Johnson. there's quite a lot more. mineral availability shoots through the roof - up to more than 1000% for iron and manganese ... blessings

I'd agree only to the point that there isn't a direct correlation but not that there isn't any correlation. Although soil may in some cases not be a critically essential component of the system (eg hydroponics and aquaponics) but soil can be a useful framework for providing the essentials plants need, and a vibrantly living soil which is more than simply inorganic minerals can easily support the biome plants need. Even in systems that don't involve soil, same if not similar functionality must be supported to enable nutrient uptake into plants.

Long on academics and short on experience. My personal opinion... The Johnson/Su bioreactor is fundamentally flawed compared to what standard hot composting accomplishes in 90 days if it's done right and the standard way is always standard that any new method should be measured against. Of course, the Johnson/Su bioreactor is one way to try to avoid the onerous manual labor of turning a hot compost pile up to 12x over a 90 day period. That's a showstopper for a lot of folks because turning a cubic yard of wet compost is a lot of heavy work. But, you have to know what the objective is... Proper hot composting ensures a complete decomposition of material with a full, rich biome that's perfect for any kind of plants. There isn't any worry about pH, nutrients or the living organisms necessary to facilitate nutrient uptake in any kind of plant. The problem with the Johnson/Su bioreactor like every other "no turn" design is that you just won't get the jet black results of regular composting completely devoid of any root or fibrous matter. Every picture of every Johnson/Su bioreactor including the inventors' own video show brown compost and all types of undecomposed matter. Anyone who has ever done a proper hot compost would never find the results of a no-turn compost pile acceptable. The other thing about the Johnson/Su bioreactor is the use of worms after the pile has cooled down. If you read the Johnson/Su academic paper, it describes adding the worms almost as an afterthought to fix a failed hot composting result. This should be compared with simply doing worms from the beginning. When you do vermicomposting (worm composting), unlike hot composting you cannot decompose fibrous and large, thick blocks of material up to 2" in diameter. If worms are fed only what can be broken down quickly which is the usual case, you'll probably find that with a decent number of worms in a large (eg 3'x8'x1') worm bin, you can probably process a full cubic yard over the course of a year like the Johnson/Su bioreactor and save yourself the trouble of doing the hot compost step. If you want to do hot composting and want to avoid the backbreaking work of turning the pile, get some heavy machinery to do the work. Or, make a deal with the neighborhood kids. For right now, I haven't seen a single "no turn" system that can process a hot compost pile and produce a result from turning the pile repeatedly and everyone who has ever published a result of a no-turn method and been happy with the result has never done a hot compost pile properly for comparison. So no... IMO there is no value in this composting design, and it's better to simply go back to the original standard ways of composting no matter if you're a small backyard operation or a large commercial business.

@@jacknissen6040Believe you're missing the point, it's building the hospitable environment as well as possible so the organisms flourish. In the case of hot composting, it's breaking down the fibrous plant material so it's easily digestible by microorganisms that mostly can't masticate. The blacker your compost, the more the soil has been broken down into fundamental carbon.

@@tonysu8860 you got me beat on vermicomposting as i’ve only been doing it for about 10 years, and hot composting for about the same. I’ve also been experimenting with Johnson-Su for about 3 years now. I’ve just started with Bokashi (fermented) compost too. Each style has its pros and cons. The main benefit to J-S compost is the fungal dominance and the wide variety of Bacteria. Up to this point, J-S is the best compost method to get that fungi well established to go through its full life cycle to reproduce spores. Every time someone turns a hot compost pile, they destroy the fungal hyphae (root hair like structures) which means the fungi have to start over again, while the bacteria survive and thrive through the turning process. Versus with a J-S , aerated but no-turn, the fungi hyphae can spread throughout the pile, grow, eat (decompose the feedstock) and go to spores (fungi “seeds”). The con is that the fungi takes longer (approximately 1 year) to get to that stage. The benefit of applying the beneficial fungi to one’s farm or garden is even more fertility than traditional hot compost and the beneficial fungi can out-compete the bad fungi. The addition of worms gets the added benefits that come from the worm castings. There is a well established and growing body of evidence to the practical positive effects of using J-S compost, even on large scale farming. From my own experience, I am friends with an amish farmer, who owns ~30 acre orchard of mostly peaches, some apple, and some cherries. He is currently switching from conventional chemical fertilizers and pesticides to chem-free. (He and his family were getting major health problems from all the chemicals.) After a really poor harvest the first year, he was seeing signs of the same issues the 2nd year (last summer) with just a few weeks before harvest of the peaches, he was really looking for something to help. I offered him 2-3x 5-gallon buckets of my Johnson-Su compost and he gladly accepted. He made an extract and sprayed his trees. He witnessed a complete stop to the problem and was able to harvest his crop a few weeks later. This is after spending thousands on natural fertilizers, seeing some benefits but still he was going to lose his main crop 2 years in a row. He credits the saving of his crop to what I gave him. He is a believer and is setting up his own J-S system. Pretty cool to know something i was “puttzin’ around with” helped my friend save his crop.
