Yes, farmers can use biodegradable mulch films on organic farms without affecting their organic certification. Biodegradable mulch films are designed to break down naturally in the soil, reducing environmental impact. However, it's crucial to ensure the mulch films meet the specific standards set by organic certification bodies. These standards vary by region, so it's important to check with the certifying agency for the acceptable materials and methods. Compliance with these guidelines will allow farmers to maintain their organic status while benefiting from the advantages of biodegradable mulch films.
