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

Farmers use agricultural plastic mulch to improve soil quality in several ways. Firstly, it helps to retain soil moisture by reducing evaporation, which is crucial for plant growth, especially in arid regions. Secondly, mulch can increase soil temperature, which can lead to faster germination and earlier harvests. It also suppresses weed growth, reducing competition for nutrients and water. Additionally, plastic mulch can improve soil structure by preventing compaction and encouraging the activity of earthworms and other beneficial organisms. Lastly, it can reduce soil erosion by protecting the soil surface from wind and water. Overall, the use of plastic mulch can lead to increased crop yields and improved soil health.
