The compost pile is turned regularly in order to make sure air/oxygen can reach all parts of the pile to support aerobic (air needing) organisms. See https://ilsr.org/home-composting/ 

For the pile, use approx 2-3 parts brown materials to 1 part greens: https://ilsr.org/workshop-home-composting-sept2023/
