ClearPolyethylene microplastics alter root functionality and affect strawberry plant physiology and fruit quality traits
Strawberry plants grown in soil with small polyethylene microplastics (35 micrometers) produced fruit that weighed 42% less and had lower sugar and antioxidant content. The tiny plastic particles stuck to roots and disrupted the plant's water uptake, leading to reduced photosynthesis and increased root stress. These findings raise concerns about how microplastic contamination in agricultural soil could affect the quality and nutritional value of the food we eat.
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.

Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.

Microplastics in terrestrial ecosystem: Exploring the menace to the soil-plant-microbe interactions
This review summarizes existing research on how microplastics affect the complex relationships between soil, plants, and soil microbes. Microplastics alter soil structure, change the makeup of microbial communities, and disrupt beneficial partnerships between plants and helpful fungi and bacteria. These disruptions can reduce plant growth and nutrient cycling, which could ultimately affect crop yields and the quality of food produced on microplastic-contaminated farmland.
Microplastics from agricultural mulch films: a threat to growth promoting abilities of bacteria?
Researchers tested how microplastics shed from agricultural plastic mulch films affect soil bacteria that promote plant growth, finding that mulch-derived microplastics reduced the abundance and activity of key plant growth-promoting bacteria. The results suggest agricultural plastic use could undermine soil health and crop productivity.

This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.

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.
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.
Impact of microplastics on terrestrial ecosystems: A plant-centric perspective
This review focuses on how microplastics affect plants and soil health in agricultural settings, an area that has received less attention than marine microplastic pollution. The researchers describe how microplastics can alter soil structure, disrupt microbial communities, and enter plant tissues through unique transport mechanisms. The study highlights that agricultural soils are a major sink for microplastics, with potential consequences for food safety and crop productivity.
Response of soil biochemical properties and ecosystem function to microplastics pollution
This study found that polyethylene microplastics significantly disrupted soil health by reducing enzyme activity, lowering nutrient availability, and impairing overall ecosystem function. Smaller microplastics caused more damage than larger ones, and the effects were dose-dependent, suggesting that as microplastic pollution accumulates in agricultural soil, it could increasingly threaten the soil health that food production depends on.

Effects of micro(nano)plastics on higher plants and the rhizosphere environment
This review examines how micro- and nanoplastics affect higher plants and the soil environment around their roots.

This review examines how microplastic contamination in soil affects plant growth through multiple pathways, including blocking water and nutrient absorption through roots, triggering harmful levels of reactive oxygen species, and disrupting hormone regulation. The effects vary depending on the type, size, and amount of microplastic present. Since plants are the foundation of our food supply, understanding how microplastics impair crop health is directly relevant to food safety and human nutrition.
The short-term effect of microplastics in lettuce involves size- and dose-dependent coordinate shaping of root metabolome, exudation profile and rhizomicrobiome
Researchers exposed lettuce plants to polyethylene plastic particles of four different sizes and concentrations, finding that the plastics altered root chemistry, changed what the roots released into the soil, and shifted the bacteria living around them. The effects depended strongly on particle size, with smaller particles causing different metabolic changes than larger ones. This study shows that microplastics in farm soil can change the biology of food crops from the roots up, potentially affecting both crop health and nutritional quality.
