Can biodegradable mulch be used to reduce soil erosion and improve water usage in dryland farming?

Yes, biodegradable mulch can be effectively used to reduce soil erosion and improve water usage in dryland farming. Mulch acts as a protective barrier that minimizes the impact of raindrops on the soil, reducing the detachment and transport of soil particles, thereby decreasing erosion. Additionally, mulch helps to retain soil moisture by reducing evaporation, allowing water to be used more efficiently by plants. As the mulch decomposes, it also adds organic matter to the soil, which can improve soil structure and water-holding capacity, further enhancing water usage in dryland conditions.
