Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality
Researchers studied how polyethylene microplastics at different concentrations affect soil microbial communities and overall ecosystem function in a maize growing system. They found that higher concentrations of microplastics shifted microbial community composition, reduced beneficial bacteria involved in nutrient cycling, and impaired multiple soil ecosystem functions simultaneously. The study suggests that microplastic contamination in agricultural soils can undermine the biological processes that support healthy crop growth.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
Microplastic residues in wetland ecosystems: Do they truly threaten the plant-microbe-soil system?
Researchers used a controlled pot experiment to assess microplastic effects on wetland plant growth, soil microbial communities, and nutrient cycling, finding that MPs altered soil enzyme activity and shifted bacterial community composition but had variable effects on plant growth depending on plastic type.
Potential impacts of polyethylene microplastics and heavy metals on Bidens pilosa L. growth: Shifts in root-associated endophyte microbial communities
Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.
Soil microbial community parameters affected by microplastics and other plastic residues
Researchers conducted a meta-analysis examining how plastic residues, including microplastics, affect soil microbial communities. The study found that plastics accelerated soil organic carbon loss and reduced microbial biomass overall, with effects varying by polymer type: polyethylene decreased microbial richness while polypropylene increased it, and the impact on microbial activity followed a dose-response pattern with a turning point around 40 grams per kilogram of soil.
Time-dependent effects of microplastics on soil bacteriome
Researchers studied how six common types of microplastics affect soil bacteria over time at realistic contamination levels. The effects were slow to appear due to the chemical stability of plastics, but over time, microplastics altered bacterial community structure and soil functions in ways that differed by plastic type. This matters because changes to soil bacteria can affect nutrient cycling and crop health, with potential downstream effects on food quality.
Effects of microplastics on common bean rhizosphere bacterial communities
Researchers studied how polyethylene and biodegradable microplastics affect bacterial communities in the root zone of common beans. Both types of microplastics significantly altered the diversity and composition of rhizosphere bacteria, with biodegradable microplastics inducing more distinctive changes than conventional polyethylene at higher concentrations.
Microplastic-contamination can reshape plant community by affecting soil properties
Researchers investigated how polyethylene and polypropylene microplastics affect naturally germinated plant communities by altering soil properties.

Microplastics alter microbial structure and assembly processes in different soil types: Driving effects of environmental factors
Researchers investigated how biodegradable polylactic acid and conventional polyethylene microplastics affect soil microbial communities across different soil types. They found that PLA increased dissolved organic carbon and pH while decreasing nitrogen availability, whereas polyethylene had contrasting effects depending on soil type. The study reveals that microplastic impacts on microbial community structure and assembly processes are soil-type-specific, with dissolved organic carbon driving changes in red soil and pH being the primary factor in fluvo-aquic soil.

This review examined microplastic interactions within the plant-microbe-soil system, finding that microplastics affect soil physicochemical properties, alter microbial communities, and can be taken up by plants, with implications for food safety and ecosystem health.
Effects of polypropylene micro(nano)plastics on soil bacterial and fungal community assembly in saline-alkaline wetlands
Scientists found that polypropylene nano-sized plastics disrupted soil bacterial communities more severely than micro-sized particles in saline wetland soil, reducing network complexity and altering how communities form. Bacteria were more sensitive to the plastic stress than fungi, and nanoplastics disrupted important interactions between soil microbes and plants. This suggests that as plastics break down into ever-smaller pieces in the environment, their impact on soil health may actually increase.
Microplastics Can Change Soil Properties and Affect Plant Performance
Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.

The findings suggest that biodegradable microplastics may affect soil health differently than conventional plastics, but are not necessarily harmless.
