How do agricultural plastic products reduce the use of pesticides and fertilizers?

Agricultural plastic products, such as mulch films and greenhouses, can reduce the use of pesticides and fertilizers by creating a controlled environment that minimizes the need for these chemicals. Mulch films can suppress weed growth, reducing the need for herbicides. They also help retain soil moisture, reducing water loss and the need for additional irrigation, which in turn can decrease the leaching of fertilizers. Greenhouses can protect crops from pests and diseases, reducing the need for pesticides. Additionally, they allow for precise control of nutrient application, leading to more efficient use of fertilizers and less runoff. Overall, these plastic products can enhance crop yields while reducing chemical inputs, promoting sustainable agriculture.
