Biodegradable Film Mulching Increases Soil Carbon Sequestration and Microbial Network Complexity in a Long-Term Field Study
Scientists studied biodegradable plastic mulch (the plastic sheeting farmers use to cover soil) and found it helps soil store more carbon and support healthier microbial communities compared to regular plastic mulch. However, the biodegradable plastic still breaks down into microplastics in the soil, raising questions about long-term environmental effects. This matters because while biodegradable farm plastics may help fight climate change by storing carbon, we still need to understand how the microplastics they leave behind might affect our food system.
Possible hazards from biodegradation of soil plastic mulch: Increases in microplastics and CO2 emissions
Researchers conducted an 18-month experiment to study whether biodegradable plastic mulches actually break down fully in soil or leave behind microplastic fragments. They found that the biodegradable mulches did generate microplastics and also increased soil carbon dioxide emissions compared to conventional mulch. The study raises questions about whether biodegradable mulches are truly more environmentally friendly than standard plastic film when microplastic generation and carbon release are considered.
