Farmers use agricultural plastic to improve soil fertility in several ways. Plastic mulches can increase soil temperature, which promotes faster plant growth and germination. They also reduce soil erosion by minimizing water runoff and wind, thereby conserving soil moisture. Mulches can suppress weed growth, reducing competition for nutrients and water. Additionally, plastic films can help in the decomposition of organic matter, releasing nutrients back into the soil. In some cases, plastic is used in drip irrigation systems to deliver water and nutrients directly to plant roots, increasing efficiency and reducing water waste, which also contributes to soil health.
