How do farmers use agricultural plastic mulch to increase crop yields?

Farmers use agricultural plastic mulch to increase crop yields by applying it over the soil around the base of plants. This practice helps to retain soil moisture by reducing evaporation, which is crucial in arid regions. The mulch also helps to regulate soil temperature, providing a warmer environment that can extend the growing season and promote earlier maturation of crops. Additionally, it suppresses weed growth, reducing competition for nutrients and water. By controlling soil-borne diseases and pests, plastic mulch can also improve the overall health of the crops. These factors combined can lead to higher crop yields and improved quality of produce.
