What are the advantages and disadvantages of using biodegradable agricultural plastic mulch?

Biodegradable agricultural plastic mulch offers several advantages, including reduced plastic pollution, as it decomposes naturally over time, and improved soil health by enhancing microbial activity. It can also retain soil moisture, suppress weeds, and maintain soil temperature, which can lead to increased crop yields. However, it has its disadvantages, such as potentially higher costs compared to conventional plastic mulches, slower decomposition rates that may not align with crop cycles, and concerns about the effectiveness of weed control and temperature regulation. Additionally, the performance of biodegradable mulches can vary widely, and there may be a lack of clear standards and certifications regarding their biodegradability, leading to inconsistent quality and environmental impact.
