ClearThe Ecological Trap: Biodegradable Mulch Film Residue Undermines Soil Fungal Network Stability
Researchers compared microplastic accumulation, soil fungal communities, and ecological network stability under conventional polyethylene and biodegradable PLA+PBAT mulch film residues in a maize field. Both film types disrupted fungal network stability, but biodegradable films produced smaller MP particles that penetrated soil more deeply and altered fungal diversity differently.
Microplastics in agroecosystem – effects of plastic mulch film residues on soil-plant system
This review examines how residues from both conventional polyethylene and biodegradable plastic mulch films accumulate in agricultural soils and affect plant growth and soil health. Both types of mulch film residues are found to have negative effects on the soil-plant system, raising questions about the environmental safety of biodegradable plastic alternatives.
Interactions of microplastics and cadmium on plant growth and arbuscular mycorrhizal fungal communities in an agricultural soil
Researchers studied how polyethylene and polylactic acid microplastics interact with cadmium contamination to affect maize growth and beneficial soil fungi in agricultural soil. While polyethylene showed minimal direct plant toxicity, high doses of polylactic acid significantly reduced maize biomass, and both plastic types altered the communities of root-associated fungi. The study suggests that co-contamination of microplastics and heavy metals in farmland can jointly disrupt plant health and soil ecosystems.

Agricultural mulching and fungicides—impacts on fungal biomass, mycotoxin occurrence, and soil organic matter decomposition
Researchers studied how plastic mulch and straw soil coverings affect the fate of fungicides applied to crops, finding that plastic mulch reduced fungicide entry into soil and altered soil fungal communities. The study highlights how plastic agricultural practices create complex interactions with other chemicals, including effects on microorganisms important for soil health.
Soil Microbial Biomass and Microarthropod Community Responses to Conventional and Biodegradable Plastics
Researchers assessed the medium-term effects of conventional polyethylene plastic mulch versus biodegradable alternatives on soil microbial biomass and microarthropod communities. They found that both plastic types and their residues in soil influenced biological communities over time, though the specific impacts differed between conventional and biodegradable materials. The study provides evidence that switching to bioplastic mulches may alter, but not necessarily eliminate, the effects of plastic residues on soil ecosystems.
Arbuscular mycorrhizal fungi enhance maize cadmium resistance and reduce translocation: Dependence on microplastics concentration
Researchers investigated how beneficial soil fungi called arbuscular mycorrhizal fungi can help maize plants resist cadmium toxicity in soils contaminated with both microplastics and heavy metals. They found that high concentrations of polyethylene microplastics worsened cadmium toxicity, but inoculation with mycorrhizal fungi significantly improved plant growth, nutrient uptake, and photosynthesis. The study suggests that these fungi could serve as a biological tool for managing crop health in soils with combined microplastic and heavy metal contamination.
Effects of Biodegradable Film and Polyethylene Film Residues on Soil Moisture and Maize Productivity in Dryland
Researchers found that biodegradable agricultural films are a viable alternative to conventional polyethylene mulch films, with higher degradation rates and less impact on soil moisture and maize root growth, ultimately improving grain yield and water use efficiency over a two-year field experiment.
Composted PBST Biodegradable Mulch Film Residues Enhance Crop Development: Insights into Microbial Community Assembly, Network Interactions, and Soil Metabolism
Researchers studied how composting residues from PBST biodegradable mulch film affect crop development, soil microbial communities, and soil metabolism. The study found that while biodegradable mulch films are designed to break down completely, their residues can persist and transform into microplastics, though composting these residues appeared to enhance crop development through changes in microbial community assembly and soil metabolic processes.
Agricultural mulch films as soil microplastic contamination factor
This review examines agricultural mulch films as a source of soil microplastic contamination, summarizing evidence on degradation rates, particle accumulation in soil profiles, and impacts on soil properties and biological communities over time.
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.
Plastic mulch film residues in agriculture: impact on soil suppressiveness, plant growth, and microbial communities
Researchers tested the effects of low-density polyethylene and biodegradable mulch film residues on soil disease suppressiveness, plant growth, and microbial communities. They found that while 1% plastic residues did not affect the soil's ability to suppress Fusarium disease, plant biomass decreased and nutrient status changed in the presence of plastic. Notably, the microbial communities on the plastic surfaces (the plastisphere) were distinct from those in the rhizosphere and included potential plant pathogens like Rhizoctonia.
Effect of microplastics on rhizosphere and arbuscular mycorrhizal fungi of Zea mays
Researchers exposed maize to two types of polyethylene microplastics (0.1% and 0.5% w/w) in glasshouse conditions for seven weeks and measured effects on rhizosphere fungi and arbuscular mycorrhizal fungi. Mycorrhizal root colonization, spore abundance, and fungal diversity were significantly reduced in a concentration-dependent manner, potentially impairing plant nutrient uptake.
Plastic mulching in agriculture. Trading short-term agronomic benefits for long-term soil degradation?
This study examined plastic mulch use in agriculture, arguing that short-term crop benefits come with long-term costs as mulch fragments accumulate in soil as microplastics and disrupt soil structure, biology, and water dynamics.
The Succession of Bacterial Community Attached on Biodegradable Plastic Mulches During the Degradation in Soil
Researchers studied how bacterial communities colonize and change over time on biodegradable plastic mulches buried in soil for five months. The study found that plastic composition and incubation time significantly shaped microbial communities, and notably, potential pathogens were detected at higher levels on biodegradable plastics compared to conventional polyethylene mulch.
Microplastics modify plant-arbuscular mycorrhizal fungi systems in a Pb-Zn-contaminated soil
Researchers examined how six types of microplastics affect sweet sorghum growth and soil fungal communities in soil contaminated with lead and zinc. They found that microplastics generally did not inhibit plant growth and in some cases promoted it, but they increased the uptake of heavy metals into plant shoots. The study suggests that microplastics may worsen the risks of heavy metal contamination in agricultural soils by enhancing metal accumulation in crops.
