What is one beneficial function of mulch?

Mulch serves several beneficial functions in managing soil health and erosion control, and one of its primary roles is to protect soil from raindrop erosion. When rainfall occurs, the impact of raindrops can dislodge soil particles, leading to erosion and loss of soil structure. By covering the soil surface, mulch acts as a barrier that absorbs the kinetic energy of raindrops, effectively minimizing their impact on the soil. This protective layer helps to maintain soil integrity, reducing erosion and promoting better water retention and soil moisture levels.

Furthermore, mulch can enhance the overall health of the soil by suppressing weed growth, regulating soil temperature, and decomposing over time to improve organic matter. This function of preventing soil erosion is particularly important in areas susceptible to water runoff and erosion, such as gardens, landscaped areas, and exposed soil surfaces.
