What is most likely to be included in a compost heap?

Lawn clippings are a common and beneficial component of a compost heap. They are a source of green material, which is rich in nitrogen—an essential nutrient that helps to promote microbial activity during the decomposition process. The high nitrogen content from lawn clippings contributes to the overall health and balance of the compost, helping it to break down more effectively.

Composting is an effective way to recycle organic materials and improve soil health, and lawn clippings typically break down quickly. Their inclusion can help create a nutrient-rich compost that supports plant growth when the compost is eventually used in gardens or landscape projects. In contrast, options like gravel and sand are inorganic materials that do not decompose or contribute to the composting process, while stumps of trees would take significantly longer to break down and are typically not suitable for standard compost heaps due to their size and density.
