What is the main benefit of using peat moss in soil?

• A. Improves nutrient content
• B. Helps to keep soil moist
• C. Enhances soil pH levels
• D. Prevents soil erosion

Answer: (B)

The main benefit of using peat moss in soil is that it helps to keep soil moist. Peat moss is highly absorbent and can retain moisture effectively, which is crucial for maintaining the right level of hydration for plants, particularly in drier conditions. This characteristic allows plants to access water more readily, promoting healthier growth and improving overall plant health.

While peat moss does contribute to the soil structure and can influence nutrient retention, its primary role in soil amendment is moisture retention. Its fibrous texture helps create air pockets in the soil, improving aeration, but the essential benefit pertains to its moisture-retaining capabilities.

The other options, such as improving nutrient content, enhancing soil pH levels, and preventing soil erosion, do not accurately capture the primary function of peat moss. Although peat moss does offer some benefits in those areas, its standout quality remains its ability to retain moisture, making it a valuable addition to garden and potting mixes.
