Composting can also suppress plant diseases, and eliminate need for chemical fertilizers

Helps Prevent Pollution: by composting organic materials instead of placing them in landfills it avoids the production of methane and leachate. Cons: Compost piles can smell if correct balance of materials is not maintained.
