Yes, farmers can use biodegradable mulch to reduce environmental pollution. Biodegradable mulch decomposes naturally over time, reducing the need for synthetic materials that can harm the environment. It helps to suppress weeds without chemicals, retain soil moisture, and enrich the soil with nutrients as it breaks down. This approach minimizes plastic waste and runoff, which can be detrimental to soil health and water quality, thus contributing to a more sustainable agricultural practice.
