ClearDoes the Incorporation of Biochar in Biodegradable Mulch Films Affect Soil Carbon Stock?
This review examines whether adding biochar to biodegradable agricultural mulch films can improve their environmental profile by increasing soil carbon, but concludes the evidence is insufficient — the combination could alter greenhouse gas emissions and microbial diversity in unpredictable ways. The paper also notes that biodegradable mulch films still generate microplastic residues in soil, meaning more research is needed before they can be treated as a clean replacement for conventional plastic films.
Effect of Long-Term Biodegradable Film Mulch on Soil Physicochemical and Microbial Properties
Long-term use of biodegradable mulch film was compared to conventional plastic and no-mulch controls in terms of soil physical, chemical, and microbial properties, with results showing that biodegradable mulch altered soil structure and microbial diversity in ways differing from both conventional plastic and bare soil. The findings raise questions about the cumulative effects of biodegradable plastic residues on agricultural soil health.
Are mulch biofilms used in agriculture an environmentally friendly solution? - An insight into their biodegradability and ecotoxicity using key organisms in soil ecosystems
Researchers assessed the biodegradation and ecotoxicity of a commercial biodegradable mulch biofilm in soil systems. The study found that while marketed as environmentally friendly alternatives to conventional plastic mulch, biodegradable films did not fully degrade under natural soil conditions as certification standards would predict. The results suggest that more rigorous testing under realistic field conditions is needed before assuming these products are safe for soil ecosystems.

Field test on the biodegradation of poly(butylene adipate-co-terephthalate) based mulch films in soil
Researchers buried four types of supposedly biodegradable plastic mulch films — used in farming to suppress weeds — in agricultural soil for over two years and found that all four still left behind microplastic fragments. This shows that even biodegradable plastics can accumulate in soil if used repeatedly each growing season.
Are biodegradable mulch films a sustainable solution to microplastic mulch film pollution? A biogeochemical perspective
This review asks whether biodegradable mulch films are truly a sustainable alternative to conventional plastic films used in agriculture. Researchers found that biodegradable microplastics may actually accumulate more readily in soil than traditional microplastics because they require specific conditions to fully break down. The study warns that biodegradable films could alter soil carbon and nitrogen cycling, microbial communities, and greenhouse gas emissions in ways not yet fully understood.
Biodegradable Plastic Mulch Films: Impacts on Soil Microbial Communities and Ecosystem Functions
This review examines how biodegradable plastic mulch films affect soil microbial communities and ecosystem functions compared to conventional polyethylene mulches. Researchers found that while biodegradable films avoid the problem of permanent plastic accumulation, their breakdown products can still alter soil microbiomes and carbon cycling in ways that are not yet fully understood. The study highlights the need for long-term field research to determine whether biodegradable mulches are truly a sustainable alternative for agriculture.
Biodegradable Mulch for Vegetable Production. A Review
This review examined biodegradable plastic mulches as alternatives to conventional polyethylene mulch films in vegetable production, summarizing yield benefits and degradation performance. Replacing conventional plastic mulch with truly biodegradable alternatives could reduce the large amounts of agricultural microplastics shed by mulch film fragmentation.
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.
iMulch: an investigation of the influence of polymers on a terrestrial ecosystem using the example of mulch films used in agriculture
This research project studied how plastic mulch films used in farming break down into microplastics in soil, comparing conventional polyethylene films with biodegradable alternatives. The findings show that both types of mulch release microplastic particles into agricultural soil, though they behave differently in the environment, raising questions about the true sustainability of biodegradable farm plastics.
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.
Effects of incorporating biochar on soil quality and barley yield in microplastics-contaminated soils
