Can agricultural plastic mulch prevent weeds from growing?

Yes, agricultural plastic mulch can effectively prevent weeds from growing. It acts as a physical barrier that blocks sunlight from reaching the soil surface, inhibiting weed seed germination and growth. The mulch also conserves soil moisture and regulates soil temperature, which can further suppress weed development. Additionally, some mulches can be designed to release chemicals that inhibit weed growth, enhancing their weed control effectiveness.
