A hot pile slows down once the microbes in the center use up the oxygen. Turning it with a spading fork moves fresh material into the core and starts the heat again.

Turn sooner if the core passes about 140°F, since heat near 160°F kills the decomposers. NC State Extension's composting chapter says to turn the pile when the center begins to feel cool to the touch. It says a pile that is not mixed may take three to four times longer to finish. Cornell's compost temperature fact sheet says decomposition is fastest between 90 and 140°F . It says piles above 160°F can sterilize themselves, and turning above 140°F helps prevent that and t...
