A compost pile is a collection of organic waste, such as food scraps, yard trimmings, and leaves, that break down over time to create nutrient-rich soil. The materials are left to decompose naturally, aided by microorganisms, insects, and air. Compost piles are usually kept in a designated area of a garden or yard, often in a bin or pile to control the process. Once fully decomposed, the compost can be used to improve the soil in gardens, providing plants with essential nutrients and promoting healthy growth.
