Can farmers use biodegradable mulch films to reduce soil erosion and runoff?

Yes, farmers can use biodegradable mulch films to help reduce soil erosion and runoff. These films cover the soil, protecting it from direct impact of raindrops which can cause soil particles to be dislodged and carried away by water. They also slow down the velocity of water flow over the soil surface, reducing the erosive power of the runoff. As the mulch decomposes, it can also improve soil structure, increase organic matter, and enhance water infiltration, further reducing runoff and erosion. However, it's important to select the right type of biodegradable mulch film and manage it properly to ensure its effectiveness and minimize environmental impacts.
