In erosion control, what is the effect of mulch when used with seed mixes?

• A. Mulch only decorates the soil surface.
• B. Mulch prevents any ground cover from forming.
• C. Mulch helps promote ground cover and reduces soil splash during rainfall.
• D. Mulch increases weed growth and erosion.

Answer: (C)

Mulch used with seed mixes acts as a protective layer on the soil surface, helping seeds stay in place, conserve moisture, and establish quickly. It cushions the soil from the impact of raindrops, which reduces soil splash that can wash away seeds and fine particles, and it moderates soil temperature and keeps soil moisture more stable. This combination supports faster ground cover as seedlings germinate and grow under a protected, more favorable environment, ultimately reducing erosion. In short, mulch isn’t just cosmetic; it actively promotes cover and dampens rainfall energy at the surface.
