When should I turn my compost windrows?

Let the compost cascade out of the loader, to keep it as loose as possible. Turning frequency should normally be based on temperature, and should occur whenever temperatures exceed to 140° F, or drop below 90° F (see Temperature Fact Sheet).

How do you compost in layers?

Ideally, a compost pile should be made up in layers (Fig. 2.) The first layer should be coarse plant material, such as branches and twigs, to allow oxygen to circulate up through the pile. The second layer should be 6 to 10 inches of finer plant material such as leaves, grass clippings, and kitchen scraps.
