Allowed Mulches on Organic Farms and the Future of Biodegradable Mulch

Summary

All farmers know that conventional polyethylene mulch is widely used for crop production because it controls weeds, conserves soil moisture, increases soil temperature, improves crop yield and quality, has a relatively low cost, and is readily available. Conventional mulch is also widely used on organic farms although organic farmers and others have questioned its use because it is often non recyclable, and is generally made from non-biodegradable based materials.
