Earthworms help break it down. The compost is used to grow new plants” (Goldsmith 20). When putting waste into the compost pile, you need to create several layers with different types of shredded plant matter. During stratification, it helps achieve and maintain nitrogen balance. It is very useful to add "green" and "brown" items to the pile. The “green” item is rich in nitrogen. It usually includes grass clippings, fruits, vegetables and coffee grounds. “Brown” items are high in carbon and are generally dry like dead plant matter. When making compost, try to use two parts "brown" material and one part "green" material (composting yard and food).
