the compost and microbe guru around these parts is
@calliandra and she has been taking some online classes with Elaine Ingham (come on now cali don't be modest
)
haha thank you for the kind words, Shluby, I assure you, I'm not modest, just mainly confused and in the middle of sorting stuff most of the time lol
I've spent hours listening to Elaine, glad to see other people dig her info as well. She was one of the reasons I stop going after fungi so much. She had a pretty simple explanation behind why. People backed her up on it as well. I mean she's increasing yields by 300%...tell me everyone here wouldn't love to see that in our rooms/outdoors
Yeah and this is the reason I am getting turned off forums myself...
There's a really great danger of misunderstanding what Ingham is saying, because she is so good at simplifying to make complex and largely still mysterious mechanisms understandable to the broad public.
I am pretty sure that whatever she said about fungi
wasn't that they're not important - and had to do with the specific context she was talking in, a specific point she was trying to make
The Soil Food Web model - and yes, it
is but a model, though I am certain it's much closer to what is actually happening in the soil than previous chemical models propose (the chemistry being but a shadow theater of the actual biological interactions, of which the SFW is a rough sketch!) - is based on the concept of succession, each step of the way from barren soil to old growth forest showing an increment in the ratio of fungal to bacterial mass for the primary miners, but always requiring higher trophic organisms to actually cycle the mined nutrients into plant-available forms.
The part of the successional scale that does not require fungal presence can only sustain opportunistic pioneers with short and fast lifecycles that we tend to call "weeds". Well if that's what you're trying to grow, you're golden! But neither grass let alone wheat belong in that category
But as soon as you get into growing annual veggies (and that's where cannabis fits in too!), you're already at a F:B ratio of 0.5-1,
plus the higher-trophic cyclers to go with that. Amongst other things like nutrient balances we have as yet very little insight into, we need those fungi to build the macroaggregrates from the microaggregates assembled by bacterial activity and the glues they excrete in the process, stringing them together with their hyphae. This is what makes our soil build a structure that can retain water better and stay aerobic. In fact, Ingham spends large amounts of time explaining this.
What I do find interesting, is that
actually, I do not know where the marker numbers describing typical ratios for the different stages of succession actually come from.
The ecosystemic concept itself (i.e., that it takes bacteria and fungi as miners AND microbial grazers for nutrient cycling) was confirmed by experimental results published in 1985 (Interactions of bacteria, fungi and their nematode grazers: Effects on nutrient cycling and plant growth. Ecological Monographs 55:119-140.).
There is definitely going to be scientific backing for the ratios - after all, Ingham has ruined life for me by insisting on not believing anyone, until seeing data that was gained in a way that doesn't defeat the experiment (cf the classic example of trying to gain insight about microbial populations of healthy soils in a petridish gone anaerobic) - so she's not going to turn around and pull numbers out of her nose herself!
But how and where from!
I will definitely look into this!
As for compost, I can't say much at present, I'll be exploring more this year, with my vermicompost and hopefully a few thermal batches too.
Yes a thermal compost can be gotten through the thermophilic phase in a very short time.
I am positing however that TIME is still a relevant factor when we're going for those higher fungal populations. The grass won't grow faster by pulling on it.
That and of course input quality in terms of microbial diversity.
Just my working hypothesis for now
Sorry for jumping in midconversation like that, I probably missed some nuances so please forgive me!
Cheers!
