The Compost Aerator is a strong, winged aerator that will allow the entry of oxygen into your compost pile. This will allow microbes to speed up decomposition, while reducing terrible odors in the process. Simple to use: Push this compost tool down into the pile of compost, twist the handle, and pull it up. The wings deploy and initiate a more effective mixing method. When aerating the compost pile, always remember it is crucial that all matter is properly broken down.
