ClearA New Approachfor Remediating Polyethylene MicroplasticsPollution in Agricultural Soils: The Combined Effects of CompoundMicrobial Agent
Researchers developed a compound microbial agent capable of degrading polyethylene microplastics and tested it in honeydew melon and eggplant fields, finding it reduced soil microplastic levels while also improving plant growth and overall soil health.
Mitigating the detrimental impacts of low- and high-density polyethylene microplastics using a novel microbial consortium on a soil-plant system: Insights and interactions
Researchers tested a novel microbial consortium containing bacterial and fungal strains to mitigate the harmful effects of polyethylene microplastics on soil and sunflower growth. The study found that microplastics altered soil pH, electrical conductivity, and organic carbon levels, but the microbial consortium treatment helped counteract some of these detrimental effects on the soil-plant system.
Microplastics accumulation in agricultural soil: Evidence for the presence, potential effects, extraction, and current bioremediation approaches
This review examines the accumulation of microplastics in agricultural soils from sources like plastic mulching and irrigation, discussing their effects on soil properties and crop growth, along with current bioremediation approaches for removing soil microplastics.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
Extraction of Polyethylene and Polypropylene Microplastic from Agriculture Soil
Researchers examined methods for extracting polyethylene and polypropylene microplastics from agricultural soil, investigating how microplastic concentrations affect soil properties and crop productivity while evaluating density separation and other extraction protocols to improve detection and quantification of plastic pollution in agroecosystems.
Degradation of microplastics in artificially polluted soil by bacterial and fungal isolates originating from landfill leachate
Researchers tested whether bacterial and fungal isolates from landfill leachate could degrade polyethylene and polypropylene microplastics in artificially polluted agricultural soil, finding that the microbial isolates showed measurable degradation activity against both polymer types.
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.
Potential strategies for bioremediation of microplastic contaminated soil
Researchers reviewed emerging bioremediation strategies for removing microplastics from contaminated soil, highlighting the roles of plants, root-zone microbes, soil animals like earthworms, and specialized bacteria and fungi that can use enzymes to break down plastic polymers into harmless compounds. While genetic engineering of microbes shows promise for accelerating degradation, the review notes that real-world application at scale still requires significant research and development.
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 emerging contaminants on soil microbial community composition, soil enzyme activity, and strawberry plant growth in polyethylene microplastic-containing soils
Researchers found that emerging contaminants altered soil microbial community composition and enzyme activity, but these effects were suppressed when HDPE microplastics were also present in the soil, suggesting microplastics may modulate how soils respond to chemical contaminants.
Impact of Plastic Residues on Soil Properties and Crop Productivity: A Comprehensive Research Study
This agricultural field study assessed how plastic residues at varying contamination levels affect soil physical, chemical, and biological properties and crop productivity, finding that higher microplastic concentrations disrupted soil structure, reduced microbial activity, and lowered plant growth.
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.
Microbial Isolates in Microplastic-Polluted Soil
Researchers isolated and characterized microbial communities from microplastic-polluted soil, identifying bacteria capable of colonizing plastic surfaces and assessing their potential roles in plastic degradation and soil nutrient cycling.
Mitigating the effects of polyethylene microplastics on Pisum sativum L. quality by applying microplastics-degrading bacteria: A field study
A field experiment found that adding microplastic-degrading bacteria to polyethylene microplastic-contaminated pea cropland mitigated the effects on soil hydrolyzable nitrogen content, increased Shannon diversity of soil microorganisms, and partially restored normal soil microbial community structure.

Researchers developed an optimized soil purification protocol for extracting and identifying microplastic particles from agricultural soils, systematically testing and combining multiple extraction and purification steps to improve the accuracy of polymer identification across different soil types.
Assessing Microplastic Contamination Effects on Soil Microbial Communities in Agricultural Land
This study sampled agricultural soils with varying degrees of microplastic contamination to assess effects on microbial diversity, abundance, and enzymatic activity, finding that higher microplastic concentrations reduced microbial diversity and suppressed nutrient-cycling enzyme activity.
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.
Coupling polyethylene microplastics with other pollutants: Exploring their combined effects on plant health and technologies for mitigating toxicity
This review summarizes how polyethylene microplastics interact with other common soil pollutants like heavy metals and antibiotics in agricultural fields. Microplastics can absorb these pollutants and carry them into plants, making the combined exposure more harmful than either pollutant alone. The findings raise concerns about the safety of crops grown in microplastic-contaminated soil.
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.
