ClearBiodegradable 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.
Microplastics from conventional and biodegradable mulch films alter microbial necromass accumulation and organic carbon sequestration in farmland soils
Researchers compared how microplastics from conventional polyethylene and biodegradable mulch films affect soil organic carbon storage over 120 days. They found that both types of microplastics altered microbial activity and reduced the accumulation of microbial-derived carbon in soil. The study suggests that even biodegradable plastics, once broken into microplastics, may interfere with soil carbon sequestration in farmland.
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.

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.
MineralizationandTransfer of Polymer-Derived Carbonfrom Biodegradable Mulch into the Soil Microbial Biomass and OrganicMatter Pool
Researchers developed a novel isotope-tracing approach to track how carbon from biodegradable mulch films enters soil microbial biomass, organic matter, and CO2, distinguishing between catabolic and anabolic pathways. The study provides improved understanding of the fate of biodegradable mulch polymer carbon in agroecosystems, with implications for evaluating biodegradable mulch as a substitute for conventional plastic films.
Potentials of synthetic biodegradable mulch for improved livelihoods on smallholder farmers: a systematic review
This systematic review evaluates biodegradable mulch as an alternative to conventional plastic mulch in farming, which is a major source of microplastic contamination in agricultural soils. Switching to biodegradable options could help reduce the buildup of microplastics in the soil where food crops are grown.
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.
Soil constituents mediate the effects of microplastics from biodegradable mulch on soil biogeochemical properties
Researchers studied how soil constituents (organic matter, clay content) mediate the effects of microplastics from biodegradable mulch films on soil biogeochemical properties. Soil type significantly altered how MPs influenced carbon and nitrogen cycling and microbial communities, suggesting that biodegradable MPs cannot be assumed safe across all soil contexts.

Researchers tracked the fate of biodegradable mulch polymer carbon in soil using isotope tracing, finding that polymer-derived carbon enters both microbial catabolic (mineralization to CO2) and anabolic (immobilization into microbial biomass and soil organic matter) pathways, with implications for carbon cycling in agroecosystems.
Mechanism of polyethylene and biodegradable microplastic aging effects on soil organic carbon fractions in different land-use types
Researchers compared how polyethylene and biodegradable microplastics at different stages of aging affect soil organic carbon fractions across various land-use types. The study found that both types of microplastics altered soil carbon dynamics, but the effects depended on the plastic type, its degree of aging, and the specific land-use context.
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.
Does 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.

This review examines how conventional plastic mulch films break down into micro- and nanoplastics in agricultural soil, disrupting soil health, microbial communities, and plant growth. Researchers compare these effects with biodegradable plastic mulches, which are designed to decompose more safely. The study highlights that while biodegradable alternatives show promise, more research is needed to fully understand their long-term effects on soil ecosystems.
Mulch-derived microplastic aging promotes phthalate esters and alters organic carbon fraction content in grassland and farmland soils
Researchers found that microplastics derived from agricultural plastic mulch undergo aging in soil, which promotes the release of phthalate ester contaminants and alters organic carbon content. The study compared black and white polyethylene mulch to biodegradable mulch in grassland and farmland soils over eight weeks, revealing that aging characteristics and environmental impacts vary by mulch type and soil context.
