How do organic mulches benefit the soil?

• A. By decreasing soil temperature
• B. By decomposing and adding organic matter
• C. By repelling water
• D. By blocking sunlight

Answer: (B)

Organic mulches benefit the soil primarily by decomposing and adding organic matter. When organic materials such as wood chips, straw, leaves, or grass clippings are applied as mulch, they gradually break down through microbial activity. This decomposition process enriches the soil with nutrients, improving soil structure, water retention, and microbial health. As the organic matter increases, it enhances the soil's ability to support plant growth by providing essential nutrients and creating a more favorable environment for root development. Organic mulch also helps with moisture retention and can suppress weed growth, but its key advantage is the addition of organic matter over time, which improves soil fertility and overall soil health.
