what is a compost and why is it good?

A compost is a mixture of decaying organic matter, such as leaves, grass clippings, and food scraps, that is used to enrich soil. Composting is beneficial because it helps to improve soil structure, increase water retention, and provide essential nutrients to plants. Compost also helps to reduce the amount of waste that goes into landfills, as it can be used as a natural fertilizer.
