- AEA founder John Kempf discusses how to manage soil nitrogen and carbon sequestration for abundant microbial communities, the roles of water, oxygen, and soluble carbon in soil, the limiting factor for building biology (soluble carbon, not water, as many people believe), why carbon sequestration is important to crop performance, and which elements are needed to stabilize nitrogen in the soil.

I have been listening to your broadcasts for 2 years according to the extensive notes I am taking.I keep them on computer files. For the past month or two I have been listening to broadcasts a second and even third time. My knowledge has increased greatly and I am absorbing so much more the second time around. I still do not have a climate battery greenhouse but I am working towards it. I have shared on other channels some of your knowledge. The other day I shared the web address of that man in Oregon who sells fungi specifically geared to raising blueberries. I have been thinking of something that is quite popular on the web which is Hugelkultur. I am thinking all that carbon from the trees and leaves
would love some Rejuvenate and Spectrum plus some attentive earthworms!!
I also am a great believer in your guest Arden Andersen's theory that paramagnetism accelerates plant
growth so we can turnover our plants more times per year which which would be extremely useful when I do get my greenhouse.
Excellent presentation. Greetings from Germany 🇩🇪
This is a comment to an umpthteen listen on this webinar… I’m really hoping John or the team can see and pop a reply…I understand the carbon distinction well with that coming from root exudates and the biological ‘cascade’… I need to clarify though, here John opened with food as the biggest limiting factor and specifically soluble carbon, the soluble carbon clarified was … that stabilized through root exudates and biological processes. Also called liquid carbon, also called humus, and further into humus fractions etc… so why did John mention that people using Humic acid and calling it food is a misnomer…? Did I miss something. ? Improving photosynthesis improves soluble carbon flow which is also the long term highly stable carbon ‘humus’ (hard to define I know..). Help..
Thanks! This came out at a perfect time! I am prepping to build soils up better for next year!
Great point, Nitrogen is so reactive... to put it down in the fall doesn't make sense.
On that note... I am planning to add some goat manure to a plot that is not up to par yet... should I be concerned about how much I put on, not wanting to go into excess nitrogen? I am planning on using Rejuvanate on it as well as Spectrum Extra as a post-treatment.
John I love your work. been wanting for years to have it all in audio format to listen to while gardening and commuting...computer time is demanding too much time away from other activities. PLEASE consider audiobook mp3 collections...or entire audiobooks from the collections...seriously..
Hi, you are welcome to stream John's podcast on your favorite podcast platform or download the mp3s from www.regenerativeagriculturepodcast.com.
What about fall applied beef manure? I am planning to spread it in the next few weeks to get it out of the pens. Has been piled since spring. I know I should of composted it, next year that will be the plan
No tillers often have a great deal of cover on the field. As a corn plant is growing is their a good way of turning some this residue into CO2 for plant uptake ?
Spraying the residue with a microbial inoculate designed for cellulose breakdown can speed up residue breakdown and supply enough additional CO2 to produce a yield response.
Oyster mushrooms. Spawn, chunks of mushrooms, slurry from a blender, whatever. Or winecap.
Brilliant
What shud be tds of water for irrigation for sugarcane?
i have a question if fall N application is not good and do damage soluble C, why N don't hurt soluble C in spring, summer, or winter?
Waqas Ahamd I think his point was that leaving excess nitrogen in the soil without it being taken up by the soil biology and plants (becuz there’s no plants and less food) means the soil has a lot of free nitrogen roaming about that will degrade carbon sources.
N application does also solubilize C during the summer months. Hopefully, there are green plants present which can pick it up and return it to the soil, and prevent it from being lost to the atmosphere.
Hi I am from India I liked u r video
Downloaded it rewatch
That's great to hear. Thanks for watching! - The AEA Team
When putting on N-fixing bacteria on seed and as the corn plant grows is this in the form of Amino Acid or N (what type) or other?
N Fixing bacteria supply N in the amino acid form, as microbial metabolites.
John Kempf , thanks for all you do. Where can I learn more about the types of amino acids excreted by these bacteria?
@@careyjamesmajeski3203 Soil Microorganisms and Higher Plants, edited by NA Krasilnikov might be a useful starting place. Google Scholar.
John Kempf , many thanks! Appreciate your time!
Hi John, just out of curiosity. Does the worlds deserts also hold 70% water capacity? Could we then say that the deserts have sufficient minerals and water but lack the biology?
It will vary depending on the soil particle composition. It is primarily the fine clay particles which adsorb higher levels of water, rather than sand. Desert soils need to be aggregated to hold water well, which happens best with grass roots rather than tree roots.
I'm wondering if hardpans are a natural process driven by earth paramagnetism or similar .I agree that breaking through hardpans with iron intervention and keeping them open with roots is right also .im sure thte would be a deeper pan develop but thats fine and necessary .then building your organic matter on top of that without chance of rapid erosion. I'm saying this to draw attention to that hardpans are a natural process and necessary when they're not on the surface and I'm sure under the right conditions the hardpans with a deep top cover have a softer make up to them due to root educates and residues seeping into it.
I will be changing my N program
Weeds can help in building soluble carbon?
Chop n drop some biomass!!
And what about manure?
I'm in the caribbean and there is no way for me to do the soil tested or get your products for cheap. i'm so jealous of people who can access this.
What local resources do you have that you can work with? Certainly you can cover crop, and shift cultural management.
@@JohnKempfVisionBuilder because of this video i added a npk + 2S fertiliser. If there was one aea product youd recommend aboce all else, which would it be?
@@JohnKempfVisionBuilder The agricultural stores do not sell cover crops. I grow mainly vegetables. I'm trying to keep a constant rotation so that the land always has something growing in it. I have mango trees and i've noticed that where the mangoes fall, where the leaves from the mahogany tress fall the plants do not succumbed to diseases as fast, especially iron and calcium defiency. I've been watching Elaine Ingham's talks resently. I have an accidental compost (a cute 400 gallon tank where i toss old vegetables, and pulled weeds), its full of millipedes, earthworms, scorpions, roaches. I'll try to secure this so it's not rained upon too much in the incoming rain season and start going into the forest for leaves, and twigs, and other fungal foods to see if i can't get more fungal growth in there. I also do no till, except if the soil is very compacted. I've noticed a lot of fungal spores developing in certain plots of land. I have rejuvenate in seastim in my truth and will purchase them shortly. Your talk that mentions that calcium nitrate does not give an increase in calcium leaves when looking at sap analyses has me looking for another source of calcium. Calmax B is what i use for calcium, but it's calcium nitrate. It seems to work, but maybe your holocal product might be better. Do you think calcium nitrate doesn't show in the sap analyses because the calcium is rapidly incorporated into the tissues of the plant? Does it give a spike in tissue analyses/ i am currently experience a loss in cabbages because of tipburn, the more rapidly growing (bigger heads) all had to be tossed. I need something better. There is no gypsum on the island. The offer white lime, but that raises the ph and so forth.
I'm interested in all this soil building but without those bottled nutrients/fertilizers you mention.... nature doesn't need those
Right on Chris! True that nature without us doesn't need them, though some growers do need them right now to help get things back on track. And some, just like you, want to do it without products and services and thats awesome too! We encourage people using the regenerative methods we talk about without buying our products, because, as you said, its not about the products in the end -- it is learning and sharing for us to all achieve the goal of getting back to those amazingly powerful natural processes you so perfectly mention. Thats why we make these videos and our podcasts public, to spread educational information freely. Check out some of our other webinars and podcasts. And please feel free to share any non-AEA information here to help people do so. Thanks for the comments and for the work you do.
Nature may not need them, but many agricultural soils do because of the way they have been sprayed, managed, and microbially compromised.
Look up Geoff Lawton - he has been restoring degraded land all over the world, and he teaches how to do it
I was lead to believe that protein was just another name for l amino acids.
What up people got hemp
That means the pink wheat they plant in the fall is what's killing the farmers yields....but dammmmid buy that land
It's about ionic exchange people......diatomacios earth is about the most readily available molecule for ionic exchange......sequester that wildfire smoke folks.....mix diatomacious earth into your soil
Close, but wrong. Carbon is not the only food source for microorganisms. They need C, yes, but also N, P, K, Ca, Mg, Mn, S, etc etc etc. C is the primary energy source, but their bodies are made up of many different elements/molecules.This presentation is a good example of what is wrong with agriculture today; trying to simplify too much a very complex system.
It seems we are saying the same thing, carbon is the primary energy source and food source for microbes. Other elements are needed as enzyme cofactors, etc, but not as an energy source in most cases. Simple explanations are needed for the components of a complex system. We share a lot of information about the many other facets of the system in the videos on our channel. Thanks!
Raurke Goose His entire point was that they’re lacking carbon. Soil biology has the ability to rip nutrients out of places that plants cannot. That’s why we need them. They won’t run out of nutrition. Actually, soil holds wayyyy more nutrients than we think are available in the top six inches while plants and fungi reach down yards into the soil.
