a) Types of Compost Systems

• Pile Composting: Simple method where organic materials are piled up in a designated area.
• Bin Composting: Enclosed bins made from wood, plastic, or metal, which help contain the compost and control conditions.
• Tumbler Composting: Rotating bins that make mixing and aerating easier.

b) Components of a Compost System

• Organic Materials: Include green materials (nitrogen-rich, like grass clippings) and brown materials (carbon-rich, like straw or leaves).
• Air: Adequate aeration is crucial; turning the compost pile regularly helps with this.
• Moisture: Keep the compost moist, like a wrung-out sponge, but not too wet.
