How do farmers use agricultural plastic film to improve soil quality?

Farmers use agricultural plastic film to improve soil quality in several ways. Firstly, it helps retain soil moisture by reducing evaporation, which is crucial in arid regions. Secondly, the film can increase soil temperature, which is beneficial for seed germination and plant growth, especially in cooler climates. It also helps control weeds by blocking sunlight, reducing competition for nutrients and water. Additionally, plastic film can improve soil structure by allowing for better aeration and drainage, which is important for root health. Lastly, it can reduce soil erosion by providing a protective layer against wind and water. These benefits collectively contribute to enhanced soil fertility and crop yield.
