• A. True
• B. False
• C. N/A
• D. Depends on Soil Type

Answer: (A)

Organic matter is indeed an essential component of living soil, making the statement true. Organic matter refers to the decomposed remains of plants and animals, as well as various organic compounds produced by soil organisms. It plays several crucial roles in the soil ecosystem.

Firstly, organic matter enriches the soil by improving its nutrient content, which is vital for plant growth. As organic matter decomposes, it releases essential nutrients and minerals that plants need. Secondly, it enhances soil structure by promoting aggregation, which improves aeration and drainage, facilitating root growth and water infiltration. This is especially important in water-efficient landscaping practices, as good soil structure helps reduce runoff and soil erosion.

Furthermore, organic matter aids in moisture retention by increasing the soil's ability to hold water, which is critical in arid and semi-arid environments. This characteristic is incredibly beneficial for landscapes designed for water efficiency, as it helps reduce the need for irrigation.

In summary, the importance of organic matter in living soil cannot be overstated. Its roles in nutrient supply, soil structure enhancement, and moisture retention make it indispensable in sustainable landscaping practices.
