Putting Fungi in the Soil - Gardening Beyond Basics 89
D
5:11Diego FooterHOST
Is it safe to assume that time is needed to develop the fungi that are going to benefit the soil or using quick compostable ingredients and a lot of turning where you're generating all this heat, do you think you can build up fungi in a pile like that, given your knowledge of fungi and how they proliferate?
P
5:35Peter McCoyGUEST
The first question is, what kind of fungi? There's anywhere from 1.5 to 6 million fungal species in the world, and many of them live in the soil.
P
5:47Peter McCoyGUEST
What kind? And there's huge questions there because we can't isolate some fungi of the soil, as I said early on.
P
5:58Peter McCoyGUEST
Trichoderma is one, but there's many other molds you can isolate from the soil and look at and name.
D
10:40Diego FooterHOST
say are the types of fungi you want to encourage or add to the soil to thrive in that environment, knowing that those are the food sources?
Plant-Fungi Relationships - Gardening Beyond Basics 78
D
10:34Diego FooterHOST
But if you're rotating these crops through Brassica to something else a- and you're breaking up the relationships, if we're just looking at the mycos- or the rhizosphere, no, mycosphere, then are we, are we doing damage by that crop rotation, or should we have crops in the same place, which contradicts a lot of traditional ag thinking of crop rotation, where we're breaking up a lot of these relationships that are forming below the soil?
P
11:08Peter McCoyGUEST
The logic, yeah, in my mind, draws to what you're, you're pointing to, a no-till practice and a, a, a reduced or, or different type of rotation practice perhaps.
P
11:18Peter McCoyGUEST
Maybe you swap out rather than a completely different type of plant in a bed, it's just a different Brassica the following year.
P
11:24Peter McCoyGUEST
Not being as rich of a plant grower, not having nearly as much knowledge about it as, as yourself or probably many of your viewers, I can only say so much about good plant-growing practices.
P
11:33Peter McCoyGUEST
But I have to imagine that a lot of that knowledge, a lot of that insight from traditional growers developed in this, the notion of rotation and all these, these things in tilling, came in by witnessing plant, uh, root pathogens and, and root rot and all these things coming in.
P
11:46Peter McCoyGUEST
And again, the, obviously, the notion is you wanna move it so that you don't establish a problematic organism in the soil.
P
11:53Peter McCoyGUEST
And I, I definitely have to wonder if those things pop up just like they do in really any system in, inside of any unhealthy organism in the environment.

Fungal Tissue and Their Carbon - Gardening Beyond Basics 68
D
1:02DiegoHOST
What is now in the soil when other microorganisms can come digest that? What, what is it made out of?
P
1:08Peter McCoyGUEST
The cells of mycelium are pretty similar internally to animal cells and plant cells.
P
1:18Peter McCoyGUEST
Prokaryotes are bacteria with really simple cells, and the eukaryotes are more evolved.
P
1:24Peter McCoyGUEST
So animal cells are just kinda like water balloons, and we have all the organelles and the nucleus and things inside that, but the, the ...
P
1:31Peter McCoyGUEST
We have soft tissue, right? Plants have a cell wall that includes cellulose, hemicellulose, and potentially lignin if it's a more woody plant, and that gives the plant structure to grow upright without flopping over, unless it's a simpler plant.
D
6:21DiegoHOST
For a lot of the, the fungi that pair up with plants, do you have any sense of how much of the carbon that makes them up is coming from the plants? Are, are they 100% dependent upon those plants to survive? That's where they're getting the carbon, or can they synthesize that themselves from other organic matter in the soil?
The Role of Fungi in Agriculture - Gardening Beyond Basics 58
P
1:39Peter McCoyGUEST
Again, the rule of thumb, and it's not to disparage anybody or any group, it's just I go into any educational system, any new setting of talking to people, assuming that most people don't know anything.
P
1:56Peter McCoyGUEST
Most people don't learn that on our education systems and on them in the mainstream media.
