How do farmers monitor the degradation of agricultural plastic films in their fields?

Farmers monitor the degradation of agricultural plastic films in their fields through several methods. Visual inspection is a common approach, where farmers regularly check the films for signs of wear, such as discoloration, cracking, or thinning. They may also use mechanical tests to assess the films' strength and flexibility. Scientific methods, like spectroscopy or chemical analysis, can determine the chemical composition changes indicating degradation. Additionally, farmers might employ soil sampling to analyze the presence of plastic residues, which can indicate the breakdown of films. Some modern techniques involve the use of sensors or remote sensing technology to monitor environmental conditions that affect degradation rates, such as temperature and UV exposure. Regular monitoring helps farmers decide when to replace the films to maintain their effectiveness and minimize environmental impact.
