Yes, farmers can use biodegradable mulch as an alternative to traditional plastic mulch. Biodegradable mulches, made from materials like paper, straw, or other organic substances, break down naturally over time, reducing environmental pollution. They can help retain soil moisture, suppress weeds, and improve soil health, similar to plastic mulches. However, their effectiveness and longevity may vary, and they might require more frequent replacement. It's important for farmers to consider the specific needs of their crops and local conditions when choosing between biodegradable and traditional mulches.
