Which of the following describes the purpose of mulching?

• A. To promote soil erosion.
• B. To maintain soil moisture and suppress weeds.
• C. To block sunlight to all plants.
• D. To increase the temperature of the soil excessively.

Answer: (B)

The purpose of mulching is primarily to maintain soil moisture and suppress weeds. By applying a layer of material, such as organic matter (like bark, straw, or leaves) or inorganic materials (such as gravel or plastic), on the soil surface, gardeners and farmers can create a barrier that retains moisture in the soil. This is particularly important in preventing water evaporating from the soil, especially during hot, dry periods. The mulch also acts as a physical barrier that prevents weed seeds from germinating and establishes a strong competition with desired plants for nutrients and water. This use of mulch contributes to healthier plant growth and improved soil structure over time, making it a fundamental practice in sustainable horticulture.
