ClearMicroplastic effects on soil organic matter dynamics and bacterial communities under contrasting soil environments
Researchers compared microplastic effects on soil organic matter dynamics and bacterial communities across contrasting soil environments, finding that the type of microplastic polymer and soil conditions together determine whether microbial activity and carbon cycling are stimulated or suppressed.
Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field
Researchers incubated five common microplastic polymer types in landfill soil for 14 months and used 16S rRNA sequencing to characterize the plastisphere communities that assembled on each polymer. Polymer type was a significant deterministic factor in plastisphere microbiome composition, which differed from surrounding soil communities and varied over time.
Effects of microplastics on soil microbiome: The impacts of polymer type, shape, and concentration
Researchers examined how different microplastic polymer types, shapes, and concentrations affected soil bacterial communities, finding that these physical characteristics induced distinct shifts in soil microbiome composition and diversity.
Living in the plastic age - Different short-term microbial response to microplastics addition to arable soils with contrasting soil organic matter content and farm management legacy
Adding polyethylene or polypropylene microplastics to two agricultural soils did not severely disrupt overall microbial activity or nitrogen cycling, but polypropylene reduced microbial biomass, especially in the organically managed soil. The results suggest that soil management history influences how resilient soil microbiomes are to microplastic contamination.
Influences of land use and depth profile on the characteristics of microplastics in agricultural soils
Researchers examined how land use and soil depth profile influence microplastic characteristics in agricultural soils, finding that wastewater and sludge application, plastic mulching, and atmospheric deposition are key sources, and that MP type and abundance vary with soil management practice and depth, highlighting the importance of vertical distribution in soil MP studies.
Macro and microplastics in the soil: abundance, characterization, identification, and interactions under different land uses in an agricultural sub-basin
Researchers examined the abundance, characterization, identification, and interactions of macro- and microplastics in soils under different land uses within an agricultural sub-basin, assessing how land-use patterns influence plastic pollution distribution and potential interactions with the soil environment.
Organic fertilizer facilitates the soil microplastic surface degradation and enriches the diversity of bacterial biofilm
Researchers found that organic fertilizer application facilitates surface degradation of microplastics in soil and enriches the diversity of bacterial biofilms on plastic surfaces, suggesting fertilizer use influences microplastic behavior and fate in agricultural soils.
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.
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.
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.
Deciphering the Mechanisms Shaping the Plastisphere Microbiota in Soil
Researchers characterized bacterial communities colonizing biodegradable and conventional microplastics in soil, finding that polymer type and biodegradability shaped distinct plastisphere communities, with deterministic processes playing a stronger role in community assembly than in surrounding soil.
Mechanisms and Influencing Factors Making Agricultural Soil as a Sink for Microplastics
This review examines the mechanisms by which agricultural soils act as sinks for microplastics, analyzing how soil properties, land management practices, and MP characteristics determine retention versus transport of plastic particles in the terrestrial environment.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
Microplastics Increase Soil pH and Decrease Microbial Activities as a Function of Microplastic Shape, Polymer Type, and Exposure Time
Researchers tested twelve different types of microplastics in soil and found that their effects on soil health depended heavily on the shape, plastic type, and how long they were present. Foam and fragment shapes raised soil pH the most, while polyethylene foam increased soil respiration, and several types reduced the activity of important soil enzymes. These findings help explain why microplastic studies often show conflicting results, since the specific characteristics of the plastic matter as much as its presence.
Biofilm Structural and Functional Features on Microplastic Surfaces in Greenhouse Agricultural Soil
Researchers studied biofilm formation on five types of microplastics in greenhouse agricultural soil over 30 days at two concentrations. The study found evidence of microbial enrichment on all plastic types, with biofilm community composition varying by polymer type and concentration. The findings suggest that microplastics in agricultural soils serve as distinct microbial habitats that may influence soil microbial ecology.
Microplastic effects on soil aggregation in sterilized and non-sterilized soils
Researchers tested how microplastics affect soil aggregate stability in both sterilized and non-sterilized soils, finding that microbial activity mediates much of the structural impact and that plastic type influences aggregation differently depending on soil biology.
Impact of Different Soil Tillage Practices on Microplastic Particle Abundance and Distribution
Field experiments across different tillage and fertilization regimes quantified microplastic abundance and vertical distribution in agricultural soils, finding that tillage practices significantly influenced how deeply microplastics are mixed through the soil profile.
Microplastic shape, concentration and polymer type affect soil properties and plant biomass
Experiments showed that microplastic shape, concentration, and polymer type all influence soil physical properties and plant biomass, with certain types reducing plant growth. The findings highlight that the wide variety of plastic particle types entering soils creates complex and variable ecological risks.
