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.

Researchers examined how polyethylene microplastic contamination in soil affects the bacterial communities associated with legume plant root nodules. They found that microplastic treatments accelerated nodule formation but disrupted the balance of beneficial nitrogen-fixing bacteria in the nodules. The study suggests that soil microplastic pollution may interfere with the symbiotic relationship between legume crops and their nitrogen-fixing bacterial partners.

[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.

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.
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.

Researchers assessed how polyamide, LDPE, and polypropylene microplastics affect Andisol soil properties and radish growth, finding microplastics reduced soil nitrogen cycling, disrupted microbial communities, and induced oxidative stress in plants — with effects varying by polymer type.
Micro and nano-plastics on environmental health: a review on future thrust in agro-ecotoxicology management
This review examines the growing body of evidence on how microplastics and nanoplastics affect plant health, soil microbial communities, and agricultural productivity. The study highlights that plastic accumulation in agricultural soils can alter crop growth and yield while disrupting soil ecosystem dynamics, and calls for greater attention to agro-ecotoxicology management to address these emerging threats to food production.
Root traits and rhizosphere responses as emerging bioindicators of microplastic pollution in agricultural soils: A review
This review examines how microplastic pollution in agricultural soils disrupts root growth, nutrient uptake, and the beneficial interactions between plant roots and soil microbes. Researchers found that microplastics can alter root exudation patterns, change soil structure, and shift microbial communities around roots in ways that may impair crop productivity. The study proposes that root traits and rhizosphere responses could serve as early warning indicators of microplastic contamination in farmland.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
Assessment of microplastic pollution on soil health and crop responses: Insights from dose-dependent pot experiments
Researchers combined field investigation and pot experiments to assess how microplastic contamination at different doses affects soil health indicators and crop growth performance. Field soils showed measurable microplastic contamination, and pot experiments demonstrated dose-dependent effects on soil enzyme activity, water retention, and plant growth metrics.

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.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
LDPE microplastics affect soil microbial communities and nitrogen cycling
Researchers found that adding polyethylene microplastics to soil changed the bacterial communities and disrupted the nitrogen cycle, which is essential for soil fertility and plant growth. Microplastics increased the activity of certain nitrogen-processing genes while decreasing others, shifting the balance of nutrient cycling. These changes in soil function could ultimately affect crop health and the quality of food grown in microplastic-contaminated agricultural land.

Researchers conducted a two-year field trial to study how polyethylene microplastics at environmentally relevant concentrations affect crops, soil, and microbial communities in a rice-wheat rotation system. They found that microplastics did not harm wheat growth but actually increased rice grain weight and plant height, while reducing soil nutrient levels including nitrogen and phosphorus. The study reveals that microplastics can alter soil bacterial communities and disrupt metabolic processes in ways that differ between crop seasons.
