ClearMicroplastic Pollution in Andisol: Effects on Soil Microbiology, Nitrogen Cycling, and Raphanus sativus L. Growth
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.
Microplastics Can Change Soil Properties and Affect Plant Performance
Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.
Microplastics’ impact on soil health and quality: Effect of incubation time and soil properties in soil fertility and pollution extent under the circular economy concept
A pot experiment with two Greek soils found that polyethylene and PET microplastics at 4% w/v concentrations altered soil nutrient levels, potentially toxic elements, and health indicators over 120 days, with biodegradation and soil pH influencing the effects.
Microplastics effects on wettability, pore sizes and saturated hydraulic conductivity of a loess topsoil
Researchers tested how polyethylene terephthalate (PET) and polystyrene microplastics at concentrations already found in farmland soils affect key physical properties of agricultural soil. They found that adding microplastics reduced the soil's ability to conduct water and hold moisture, with larger particles at higher concentrations causing the greatest changes. The study suggests that microplastic accumulation in agricultural soils could alter water movement and availability in ways that may affect crop growth.
Size and concentration-dependent effects of polyethylene microplastics on soil chemistry in a microcosm study
Researchers tested how polyethylene microplastics of different sizes and concentrations affect soil chemistry in a controlled lab setting. They found that the smallest microplastic particles reduced the soil's ability to hold nutrients by nearly 13% and altered dissolved organic matter, while also leaching phthalate chemicals into the soil. The study suggests that as microplastics accumulate in agricultural soils, they could impair important soil functions related to nutrient retention and pollutant movement.
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.
Effects of low‐density polyethylene and polyamide microplastics on the microbiological and chemical characteristics of an Andisol
This study evaluated the impact of low-density polyethylene and polyamide microplastics on the biological and chemical characteristics of a volcanic ash-derived Andisol soil from central Chile, assessing 21 soil parameters across microplastic treatments.
Microplastics in agricultural soils : effects on physical, chemical, and microbiological processes
This thesis examines how pristine and degraded conventional microplastics (polyethylene and PET) and biodegradable microplastics (PBAT) affect soil physical, chemical, and microbial properties across silty loam and sandy loam soils, integrating five studies involving greenhouse and laboratory experiments to assess impacts on aggregation, water-holding capacity, carbon storage, respiration, nutrient cycling, and microbial community composition.
Effects of microplastics on soil environment and land plant growth: a review
This review examines how microplastics affect soil quality and plant growth through both direct toxicity and indirect changes to soil properties. Researchers found that microplastics can accumulate in plant tissues after entering the soil and may transfer through the food chain. The study highlights that soil microplastic contamination is a growing ecological concern that remains understudied compared to marine environments.
Recent advances on ecological effects of microplastics on soil environment
This review summarizes recent advances in understanding the ecological effects of microplastics on soil environments. Researchers found that soils serve as major sinks for microplastics, which can alter soil properties, affect plant growth, disrupt soil microbial communities, and interact with other pollutants. The study highlights that terrestrial microplastic pollution may be even more pervasive than aquatic contamination and warrants greater research attention.
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.

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.
Microplastic contamination in soil environment – a review
This review examines the sources, transport, degradation, and ecological impacts of microplastic contamination in soil environments. The study suggests that soil acts as both a major sink for microplastics and a conduit transporting them to aquatic systems, and that microplastics can negatively affect soil organisms and biogeochemistry, underscoring the need for more research on terrestrial microplastic pollution.
Changes in Soil Properties Under the Influence of Microplastics in Plastic and Open Field Production in Three Serbian Valleys
Researchers examined soil physical, chemical, and biological properties in greenhouse and open-field soils across three Serbian valleys to test whether mulch film use leads to microplastic accumulation and soil alteration. Greenhouse soils showed elevated MP concentrations that correlated with changes in chemical and biological parameters, supporting the hypothesis that repeated plastic mulch use degrades soil quality.
