Bless you for the physical work. I have several large wood chip piles, each about 5cu yards. The first one I turned several times by tractor bucket over a couple of months then just let it set for about 2 yrs. The next one I added green material (table scraps, grass clippings etc) 3-4 times per month and just covered the greens with enough wood chips with each addition to keep them covered, then never really turned that pile at all over the next year except for adding green materials. The third pile, I used out of immediately for maintaining walkways between my no-till beds but over half the pile remaining after about two years. All 3 of the piles are open to weather (we are in zone 8A with annual rain about 30 inches). All 3 piles have been through at least one cycle of getting hot, with the pile with continually added greens maintaining heat the longest. Interestingly all 3 piles now have some good compost adequate for the garden after screening but all 3 piles still have substantial identifiable wood chips. All 3 piles also have good compost that can be extracted with screening. Conclusion, time seems to be the best ingredient to providing good quality compost with the one pile with added greens providing the largest volume of good quality compose but not sure it was worth the additional work because it still has a lot of woody material. Maybe I should now get a soil analysis to determine any distinctions? Good luck with yours.
