Perforated pipes provide continuous aeration, thereby eliminating the need for turning the pile. The gardeners spread finished compost in their garden at the end of fourteen weeks. Narration presents principles of composting including the need for moisture, nitrogen, oxygen, and a variety of materials.Subtitle: featuring Mary Appelhof with Mary Frances Fenton Producer: Macatawa Productions Level: Teen to Adult Specs: Video, VHS, 28 min.
