ClearResponse 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 Polyethylene Microplastics on Soil Nutrients and Enzyme Activities].
Researchers studied how different concentrations and sizes of polyethylene microplastics affect soil chemistry and enzyme activity over four months. They found that smaller microplastics had a greater impact on soil nutrient cycling than larger ones, and that higher concentrations more significantly disrupted enzyme functions critical for soil health. The study indicates that microplastic pollution in agricultural soils could impair the biological processes that maintain soil fertility.
Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
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.

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.
Effects of microplastic pollution on agricultural soil and crops based on a global meta‐analysis
This meta-analysis examined data from studies worldwide to assess how microplastic pollution affects agricultural soil and crops. Researchers found that microplastics can alter soil properties including enzyme activity and nutrient availability, with effects varying by plastic type, concentration, and size. The study suggests that microplastic contamination in farmland may affect both soil health and crop growth in ways that depend heavily on local conditions.
Integrated effects of residual plastic films on soil-rhizosphere microbe-plant ecosystem.
This pot experiment investigated how residual plastic film fragments of different sizes in agricultural soil affect soil properties, microbial enzyme activity, nutrient levels, and plant growth. Larger plastic residues caused greater disruption to soil health and reduced crop yield, suggesting that accumulated mulch film pollution poses a serious threat to long-term agricultural productivity.

This review examines the growing body of evidence on how microplastics and nanoplastics affect plant health, soil microbial communities, and agricultural productivity. The study highlights that plastic accumulation in agricultural soils can alter crop growth and yield while disrupting soil ecosystem dynamics, and calls for greater attention to agro-ecotoxicology management to address these emerging threats to food production.
Microplastic residues in wetland ecosystems: Do they truly threaten the plant-microbe-soil system?
Researchers used a controlled pot experiment to assess microplastic effects on wetland plant growth, soil microbial communities, and nutrient cycling, finding that MPs altered soil enzyme activity and shifted bacterial community composition but had variable effects on plant growth depending on plastic type.
Influence of soil microplastic contamination on maize (Zea mays) development and microbial dynamics
Researchers grew maize (corn) in soil contaminated with varying amounts of microplastics and found that higher microplastic levels disrupted soil bacteria and fungi, caused leaf damage like yellowing and tissue death, and led to elevated heavy metals in plant tissue above safe limits. The results point to serious risks microplastics pose to crop health, soil ecosystems, and food safety.
