In the composting course, Ingham starts by citing one of (or even THE) first composting manual, written by a Sir Albert Howard in the 1800's.
Step one, whatever you're up to, is to
address the pile.
So, hello compost pile
And the five billion flies living on it at the mo.
Wow. All the more reason to check whether this pile is actually anaerobic after all.
I'd be really worried if the smells weren't abating as they are - apart from that touch of sheep, it's starting to smell agreeably earthy.
Temps haven't come back up, BUT they're pretty
homogeneous throughout the pile, hottest in the middle as they're supposed to be, ranging from 51-53°C.
Except for a cold side (interestingly on the south side and getting the most sun) which has temps ranging from 38-43°C.
I took my samples like 20cm into the pile and in the homogeneous area.
And what a surprise, checking it with the microscope!
My guess was it was going to be mainly bacterial, but no!
Despite all the turning, there were pieces of fungal hyphae in almost every field of view, which is a pretty good omen for a future fungal population.
Pix!
Fungal hyphae of two different beneficial species.
Note the grainy appearance of their surfaces, those are oxalates which bind nutrients to the fungus (so they won't get washed out, as they would be in the form of soluble nutes), their pantry so to speak
And here, a sprouting one
along with something that clearly is multiplying - not sure it's a fungus, but tapping the cover slip didn't unentangle that clump there, so hard for me to say what is what.
Also, I saw tons of protozoans.
The most active ones were 3 ciliates, the anaerobic guys -- considering what the pile has been through, I wondered more that there weren't more

On the anaerobic side, I also saw a larva (possibly dead), also unsurprising, thinking of all those flies on the pile

But a surprising amount of testate amoebae, and the whole sample specked with cysts (=protozoan dormant stages).
Next pic: not sure what that cystlike thing with the blob sticking out to its left is, could be a fungal spore too. But below that, a testate amoeba, and above it and to the right, all those larger rounds are very probably flagellates.
Another thing that was nice: there's quite some bacterial diversity in there - rods (=bacilli) and rounds (=cocci) of different forms, single, double, commashaped, and a few flagellate bacteria (probably)
No nematodes, but I wasn't expecting any, as they go into flight mode and/or get squished during turns, especially the large predatory ones.
Imagine,
a bacteria multiplies in 20 mins
a fungus in 1 hour
a protozoan in ~ 8 hrs
a nematode in 2 weeks.
So when we're composting and turning, the fungi get sliced and diced, the nematodes flee or die (not sure about their eggs) in the order of their size and goodness:
predators are the largest and go first
fungal and bacterial go next
but the freaking rootfeeders, they don't mind it haha
And that's one of the reasons we have to let the pile rest after it's done heating up, so processes can calm down, and the more fragile of the critters have time to regenerate, grow, or come back (like the worms and microarthropods). It is then that any unbalance from the crazy orgy those composting days were is balanced out.
So composting begins with the trusty bacteria, which are everywhere in this earth, in the ice, in the volcano lava.
They are the ones that start things going.
Then the fungi join in, followed by the predators, protozoa and bacterial nematodes first, then fungal nems, then predator nems, microarthropods, earthworms.
It's just like in succession, just immensely sped up!
