ClearEffects 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.
Biodegradable Microplastics from Agricultural Mulch Films: Implications for Plant Growth-Promoting Bacteria and Plant’s Oxidative Stress
This study tested how microplastics from biodegradable agricultural mulch films affect beneficial soil bacteria and plant growth. The biodegradable microplastics inhibited most helpful bacteria and caused oxidative stress in plants, reducing their growth. However, some bacteria showed tolerance to the microplastics and helped protect plants from the damage, suggesting that biodegradable plastics are not harmless to soil ecosystems as often assumed.
Integrated effects of residual plastic films on soil-rhizosphere microbe-plant ecosystem.
This pot experiment investigated how residual plastic film fragments of different sizes in agricultural soil affect soil properties, microbial enzyme activity, nutrient levels, and plant growth. Larger plastic residues caused greater disruption to soil health and reduced crop yield, suggesting that accumulated mulch film pollution poses a serious threat to long-term agricultural productivity.
Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.
Soil microorganisms play an important role in the detrimental impact of biodegradable microplastics on plants
Researchers found that biodegradable microplastics harmed vegetable crop growth by disrupting the soil microbial community rather than through direct contact with the plants. When soil microorganisms were suppressed, the negative effects of the biodegradable microplastics on plant growth were also reduced. The study suggests that soil bacteria and fungi play a key role in mediating the harmful impacts of biodegradable plastics on agricultural crops.
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.
Effect of microplastics used in agronomic practices on agricultural soil properties and plant functions: Potential contribution to the circular economy of rural areas
Researchers measured the effects of microplastics used in common agricultural practices — including mulch film residues and irrigation-delivered particles — on soil physical, chemical, and biological properties. Microplastic presence altered soil aggregation, water retention, and microbial community composition, with effects depending on plastic concentration, polymer type, and soil texture.
Plastic Film Residue Reshaped Protist Communities and Induced Soil Nutrient Deficiency Under Field Conditions
Researchers conducted a field experiment to examine how long-term plastic mulch film residues affect soil microorganisms and nutrient cycling. They found that plastic residues significantly reduced the diversity of protist communities, which play key roles in soil health, and led to deficiencies in soil moisture, nitrogen, and phosphorus. The study underscores that agricultural plastic waste creates lasting negative effects on soil ecosystems well beyond its intended use.
Plastic Mulch‐Derived Microplastics in Agricultural Soil Systems
This review examines how plastic mulch films widely used in agriculture degrade via photodegradation, chemical processes, and microbial activity to form microplastics, and discusses how these microplastics affect soil properties, plant growth, soil microbiomes, and broader agricultural ecosystem health.
Microplastics increase soil microbial network complexity and trigger diversity-driven community assembly
Researchers found that microplastics in soil increased bacterial network complexity and shifted microbial community assembly in a diversity-dependent manner, with high-density polyethylene causing more harm to plant growth than polystyrene or polylactic acid particles.

Microplastics from mulching film is a distinct habitat for bacteria in farmland soil
Microplastics collected from cotton field mulch films in Xinjiang, China were analyzed by electron microscopy and 16S rRNA sequencing, revealing bacterial communities on plastic surfaces that were structurally distinct from surrounding soil, plant litter, and macroplastics. The study identifies microplastics from agricultural mulch films as novel microbial habitats with a distinct plastisphere community structure.
From the rhizosphere to plant fitness: Implications of microplastics soil pollution
Researchers exposed strawberry plants to low-density polyethylene microplastics in soil and found significant harm, including reduced chlorophyll levels, altered nutrient uptake, and increased stress responses. The microplastics also shifted the soil microbiome toward potentially harmful fungi and bacteria. These findings show that microplastics in agricultural soil can damage crop health and change the microbial community that plants depend on.

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.
