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

Farmers use agricultural plastic bags primarily for mulching, a practice that can significantly improve soil quality. Mulching with plastic helps retain soil moisture, reducing the need for irrigation and promoting plant growth. It also suppresses weed growth, conserving soil nutrients that would otherwise be competed for by weeds. Additionally, plastic mulch can increase soil temperature, which is beneficial for early-season planting and germination. Over time, as the plastic degrades, it can improve soil structure by adding organic matter, although the environmental impact of plastic degradation must be considered. These methods collectively enhance fertility, aeration, and overall soil health, leading to increased crop yields and quality.
