Biodegradable Mulching Film vs. Traditional Polyethylene: Effects on Yield and Quality of San Marzano Tomato Fruits

A two-year field trial comparing biodegradable mulching film to conventional low-density polyethylene (LDPE) for San Marzano tomato production found that both mulch types produced equivalent yield increases (25%) and improvements in fruit quality compared to bare soil. Biodegradable film began degrading in the field between 71 and 104 days after transplanting, making it a viable alternative that avoids end-of-life plastic waste. Replacing conventional plastic mulch with biodegradable alternatives could significantly reduce the agricultural microplastic burden entering soils globally.

Impact of long-term conventional and biodegradable film mulching on microplastic abundance, soil structure and organic carbon in a cotton field

Researchers compared microplastic levels in cotton fields after 23 years of plastic film mulching and found that switching to biodegradable film actually produced more total microplastics than continuing with conventional polyethylene film. The biodegradable film broke down into many small particles that also reduced beneficial soil microbes and dissolved organic carbon. This challenges the idea that biodegradable agricultural films are a simple solution to farmland plastic pollution.

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.

Building Agricultural Knowledge of Soil-biodegradable Plastic Mulch

This paper examines the slow adoption of soil-biodegradable mulching film (BDM) as a replacement for conventional polyethylene (PE) mulch in US agriculture, developing training materials and running extension education programs for farmers and agronomists. Field demonstrations showed comparable weed control and tomato yield between BDM and PE, but growers remain concerned about inconsistent degradation rates and food safety questions around plastic fragments. Accelerating BDM adoption is relevant to the microplastics problem because conventional PE mulch fragments left in fields are a major source of agricultural soil microplastic contamination.
