Which of the following is an example of inorganic mulch?

• A. Composted bark
• B. Pine needles
• C. Volcanic rock
• D. Grass clippings

Answer: (C)

Inorganic mulch refers to non-decomposable materials used to cover the soil surface, helping to conserve moisture, suppress weeds, and regulate soil temperatures. Volcanic rock is a prime example of this type of mulch. It is a natural material that does not break down over time, making it an effective long-term option for landscaping. In contrast, the other materials listed are organic mulches. Composted bark, pine needles, and grass clippings are all organic materials that can decompose and improve soil quality as they break down. While they provide benefits such as enhancing soil structure and adding nutrients, they do not have the same longevity as inorganic mulches like volcanic rock.
