ClearEffects 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.

Global meta-analysis reveals differential effects of microplastics on soil ecosystem
This meta-analysis pooled data from 114 studies to understand how microplastics affect soil ecosystems at different concentrations. Higher microplastic levels reduced soil organic matter and microbial activity, suggesting that increasing plastic pollution could degrade the soil that supports our food supply.
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.
Micro and Nanoplastics Interactions with Plant Species: Trends, Meta-Analysis, and Perspectives
This meta-analysis pooled data from multiple studies to examine how micro- and nanoplastics affect plants. It found that nanoplastics (smaller than 100 nm) are generally more harmful to plant growth and development than larger microplastics, though staple crops showed surprisingly little effect. Since plants can absorb these tiny plastic particles, the findings raise questions about whether microplastics in soil could enter the food supply.
Microplastic and Nanoplastic in Crops: Possible Adverse Effects to Crop Production and Contaminant Transfer in the Food Chain
This meta-analysis found that nanoplastics can be taken up by plant roots and transferred to the parts we eat, while also reducing crop yields. This means microplastic pollution in agricultural soil could affect both food safety and food production, creating a dual concern for human health.
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.

Soil animal body mass and reproduction decreased by 5% and 11% respectively, though soil enzyme activity increased by 7-441%.
Recent Advances on Multilevel Effects of Micro(Nano)Plastics and Coexisting Pollutants on Terrestrial Soil-Plants System
This review systematically summarizes how micro- and nanoplastics, alone and combined with co-existing pollutants, affect soil properties and terrestrial plants at multiple biological levels. Researchers found that microplastics can serve as carriers for heavy metals, organic contaminants, and biological pollutants, with their specific impacts depending on polymer type, size, shape, and concentration. Evidence indicates that plants can take up and transport micro- and nanoplastics, leading to effects on growth, metabolism, and even DNA damage.
Microplastics in plant-soil ecosystems: A meta-analysis
This first formal meta-analysis of microplastics in plant-soil systems found that microplastics made soils more porous and water-retentive but decreased aggregate stability and microbial diversity, suggesting plastics occupy physical space without integrating into the soil biophysical matrix. Maize was more sensitive than rice or wheat, and microplastics enhanced soil CO2 flux and evapotranspiration while reducing N2O flux.
