ClearEffects 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.
Interactive effects of soil characteristics and polymer types reveal patterns of denitrifying bacteria enrichment in the soil plastisphere
A field study examined how soil characteristics (texture, organic matter, pH) and polymer type interact to determine microplastic persistence and mobility in agricultural soils. The results show that soil properties are as important as plastic type in predicting environmental fate.
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.

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.
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.
Polyethylene microplastics distinctly affect soil microbial community and carbon and nitrogen cycling during plant litter decomposition
Researchers measured how polyethylene microplastics affect soil microbial communities and carbon cycling in agricultural soils, finding that microplastic addition shifted microbial diversity and suppressed key carbon mineralization processes. The results suggest microplastic accumulation in farmland could impair soil carbon storage.
The Spatiotemporal Successions of Bacterial and Fungal Plastisphere Communities and Their Effects on Microplastic Degradation in Soil Ecosystems
Researchers tracked how bacterial and fungal communities colonize microplastic surfaces in soil over time, finding that the surrounding soil type had the strongest influence on which microbes grew on the plastics. The microbial communities on microplastics were less diverse and less stable than those in the surrounding soil, but they attracted microbes with a higher capacity to break down organic carbon. The study suggests that microplastic surfaces become hotspots for carbon metabolism in soil ecosystems.
Mechanism of polyethylene and biodegradable microplastic aging effects on soil organic carbon fractions in different land-use types
Researchers compared how polyethylene and biodegradable microplastics at different stages of aging affect soil organic carbon fractions across various land-use types. The study found that both types of microplastics altered soil carbon dynamics, but the effects depended on the plastic type, its degree of aging, and the specific land-use context.

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.
[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.
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.

Researchers conducted a one-year pot experiment to study how different types and concentrations of microplastics affect soil carbon cycling and aggregate stability. They found that microplastics significantly altered soil aggregate size distribution and decreased organic carbon mineralization rates regardless of polymer type. The study suggests that microplastic contamination may slow the natural breakdown of organic carbon in agricultural soils by changing soil structure and microbial communities.
