The Compost Aerator is a sturdy, winged aerator that introduces oxygen into your compost pile, permitting microbes to speed up the decomposition process and drastically reducing the bad odors that are emitted from the pile. Simply push the aerator down into compost pile, twisting the handle and pulling it up. The wings will deploy and initiate a more effective mixing. Aerating the compost pile is important to ensure that matter breaks down properly.
