ClearAssociation of microplastics with water-stable aggregates formed under laboratory conditions
Scientists found that tiny plastic particles in soil can break apart the natural clumps that keep soil healthy and stable. Different types of plastics had different effects, with some plastics causing more damage to soil structure than others. This matters because damaged soil could affect how well crops grow and how plastic pollution moves through the environment, potentially impacting our food supply.
Small-size polyethylene and polylactic microplastic alterations on soil aggregate formation with soil sterilization
Researchers tested how small polyethylene and polylactic acid microplastics affect the formation of soil clumps, called aggregates, which are important for healthy soil structure. The microplastics changed aggregate stability through physical interactions rather than by harming soil microbes. This matters because soil structure affects how well crops grow, and widespread microplastic contamination in agricultural fields could subtly alter soil quality.
The Growing Problem of Soil Pollution with Microplastics: a Review
This review examined how microplastic accumulation in soil disrupts physicochemical properties including structure, porosity, and water retention, impairs soil microbial communities, inhibits plant growth, and causes oxidative stress, with agricultural soils identified as especially vulnerable to contamination.
Influence of microplastics on soil aggregate formation: Insights into biological binding agents
A laboratory experiment found that polyethylene microplastics in different shapes (granules, fibers, and films) and aging states significantly alter how soil particles clump together into aggregates, with effects depending on the plastic's shape and the soil's organic matter content. Disruption of soil aggregation by microplastics matters because aggregate structure controls water retention, aeration, and microbial habitat — all fundamental to healthy, productive soils.
Exploring the Impact of Micro-plastics on Soil Health and Ecosystem Dynamics: A Comprehensive Review
This review examines how microplastics affect soil health, finding that they alter soil structure, water retention, and the organisms that live in soil. Microplastics can carry toxic substances into soil and interact with other pollutants to amplify harmful effects on earthworms and soil microbes. Since healthy soil is essential for growing safe food, microplastic contamination of agricultural land could have long-term consequences for the food supply and human health.
Does plastic and microplastic change the soil physical properties? A review
This review summarizes how microplastics in soil affect physical properties such as water retention, aggregation, and aeration. Plastic particles enter soil through mulch films, sewage sludge, and irrigation water, and their accumulation threatens the health of agricultural soils that support food production.
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.
Microplastic Effects on Soil Aggregation in Sterilized and Non‐Sterilized Soils
Researchers tested how microplastics affect soil aggregation in both sterilized and biologically active soils, finding that microplastic effects on aggregate stability were strongly mediated by the presence of soil microorganisms. Biologically active soils showed different responses than sterile soils, highlighting the role of the soil microbiome.
Soil aggregation alterations under soil microplastic and biochar addition and aging process
An eight-month experiment found that polyethylene and polypropylene microplastics disrupted soil structure by breaking apart soil clumps, and this damage worsened as the plastics aged over time. Surprisingly, adding biochar, which is often proposed as a soil improvement, actually made some of the microplastic damage worse for certain soil aggregate sizes. This research shows that microplastic contamination in agricultural soil can degrade soil health in ways that may be difficult to reverse.
Microplastics DisruptSoil Aggregate Stability andAssociated Nutrient Dynamics in Mulched Salt-Affected AgriculturalSoils
Researchers investigated how microplastic accumulation and aging affects soil aggregate stability and nutrient dynamics in mulched salt-affected agricultural soils, finding that microplastics disrupt aggregate structure and interfere with nutrient storage and cycling processes critical to soil quality.

This review synthesized research on microplastic contamination in agricultural soils, examining how MPs affect soil physical properties, chemistry, and plant growth performance. It identified key knowledge gaps around MP accumulation rates, long-term soil effects, and impacts on food crop yields.
Aging microplastics and coupling of “microplastic-electric fields” can affect soil water-stable aggregates’ stability
Researchers investigated how aged microplastics from polystyrene and polypropylene affect the stability of soil aggregates, which are important for soil health. The study found that weathered microplastics can break down the structure of water-stable soil aggregates, and that the combination of microplastics with electric fields further destabilizes soil, suggesting long-term consequences for soil quality.
Formation, behavior, properties and impact of micro- and nanoplastics on agricultural soil ecosystems (A Review)
This review provides a comprehensive look at how micro and nanoplastics affect agricultural soil ecosystems, covering their sources, movement through soil, and impacts on soil organisms and crop growth. The authors found that microplastics can alter soil structure, reduce beneficial microbial activity, and affect plant nutrient uptake. These changes to farmland soils could ultimately threaten food security and introduce microplastics into the human food supply.
Microplastics in Agricultural Soils: An Emerging Threat to Soil Health, Microbial Ecology, Crop Productivity, and Food Safety
This review examines how microplastics accumulate in agricultural soils from sources like plastic mulch, sewage sludge, and atmospheric deposition. Researchers found that these particles can disrupt soil microbial communities, harm plant health, and potentially enter the human food chain. The study highlights the urgent need for mitigation strategies to address this growing but often overlooked form of pollution in farmland.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.
