>> I never turn the compost because it accumulates too fast and gets to heavy so it takes a year before I can use it.
I don't always turn my pile, but I do stir it some when I add scraps. And when I have more than one pile, I rake the dry woody outer layer off the older pile and add those to the younger pile (I "demote" slower stuff). If I only have one pile at the moment, I try to make a hole in the center, then rake the outer layuer into the center ("turn it inside out"). That reduces the amount of forking and shoveling I have to do, but still churns it slowly.
Lately, when I need compost, I've been scooping out the center of my small pile, which is finished fastet because it stays moist all the time, and .that's where I add high-N kitchen scraps.
Then I put it through a 1/2" screen to remove twigs or other large pieces. Thos let me use compost as soon as it's ready, and I think that means that my plants get more of the N and C, rather than having the compost microorganisms c onsume it and burn some of the C away as CO2, and release or leach some of the N.
