I'm a big fan of cold composting without turning because I don't have too much time and I'm lazy. I throw my yard waste into round bins made of re-purposed corrugated steel. When full, I let it settle and throw a few inches of soil on top...
I have one up North that now is two years into its not being emptied
I filled the North one with a mixture everything from a weed filled mixture of dirt, bird seed sprouted and un-sprouted, bagged mulch residue from under the bird feeder under the spruce trees, weeds and plants pulled from the garden, and excess dirt I had no place to put that would not have screwed up dirt level, therefore ; it is a bit a of a lasagna layered compost bin though I did add some compost booster last week.
It is now technically full and I am deciding if I should just let it sit for a few years, it will settle a foot or so naturally, or next spring dig a hole an bury it as I have done for most of the past thirty years, rarely using it as a compost on top of the soil.
I am curious as to what I will get up North if I let that one sit for four or five years as there are layers of genuine dirt, a couple of inches deep and wonder if that will speed up of slow the pile breaking down.
I know some years, quite a few really, I let the North one sit for some years and decided I would try turning it by hand and found in the middle a mass of mostly un-rotted old vines and other stuff which surprised me .
After opening up the middle, it shrank quite a bit that summer though using compost booster probably was the main reason..
