A nationwide assessment of microplastic abundance in agricultural soils: The influence of plastic crop covers within the United Kingdom
A nationwide study of 108 agricultural sites across the United Kingdom found microplastics in all soil samples, with concentrations averaging 3,680 particles per kilogram. Fields where plastic crop covers were used had significantly higher microplastic levels than those without plastic covers. This study shows that common agricultural plastic use is a major source of soil microplastic contamination, which could ultimately affect crop quality and enter the food chain.
The extent and impacts of soil pollution by microplastics
This study examines the extent and impacts of soil pollution by microplastics, reviewing evidence of how microplastic particles accumulate in terrestrial environments and affect soil ecosystems, organisms, and agricultural systems.
Microplastics pollution modulated by farming regimes under multi-scenarios
Microplastic concentrations in agricultural soils were found to vary with farming regimes, with certain practices under mulching leading to higher accumulation. The study highlights how common agricultural methods contribute to soil microplastic pollution and supports calls for better plastic mulch management.
[Distribution, Sources, and Behavioral Characteristics of Microplastics in Farmland Soil].
This systematic review summarizes existing research on how microplastics distribute, accumulate, and move through farmland soils worldwide. The study found that microplastics in agricultural soil come mainly from plastic mulch films, fertilizers, and irrigation water, with fibers and fragments being the most common shapes detected. Since farmland microplastics can be taken up by crops, this contamination pathway is a direct route for microplastics to enter the human food supply.
Quantification and Analysis of Microplastics in Farmland Soils: Characterization, Sources, and Pathways
This study quantified and characterized microplastics in farmland soils from multiple sites, identifying agricultural mulch films, irrigation water, and compost as major sources and documenting widespread soil contamination across different farming regions.
Distribution pattern and risk assessment of microplastics contamination in different agricultural systems
Researchers surveyed microplastic contamination in agricultural soils across six sites in Coimbatore, India with distinct farming practices, finding microplastics in 81% of organic matter-removed samples. The study revealed that different agronomic inputs and land management practices produce distinct microplastic contamination profiles.
Microplastics in soil: A comprehensive review of occurrence, sources, fate, analytical techniques and potential impacts
This review analyzed microplastic contamination data from 62 sites across 17 countries and found that soil microplastic levels varied enormously depending on land use, with agricultural and urban soils most contaminated. The plastics affected soil organisms, plants, and microorganisms in complex ways, but inconsistent sampling methods across studies make it difficult to compare results and determine safe exposure thresholds.
Microplastics in Agricultural Soil
This book chapter surveys microplastic contamination in agricultural soils, reviewing the sources of plastic inputs, concentrations found in different farming systems, and the effects of MPs on soil properties, microbial communities, and crop yields.
Amount, distribution and composition of large microplastics in typical agricultural soils in Northern Germany
Researchers surveyed agricultural soils in Northern Germany for large microplastics and found contamination across all sampled fields, with polyethylene and polypropylene being the most common polymer types. Concentrations varied widely depending on farming practices, with fields receiving compost and sewage sludge showing higher contamination levels. The study provides important baseline data on microplastic pollution in European agricultural soils and identifies fertilization practices as a key contamination pathway.
Microplastics in soils: A comprehensive review
This comprehensive review summarizes what is known about microplastics in soil, covering their sources from agriculture, household waste, and industry, as well as how they move through and accumulate in different soil types. The review finds that current methods for measuring soil microplastics are inconsistent, making it difficult to accurately assess the true scale of contamination and its risks to food safety and human health.
Impact assessment of microplastics in agricultural soils of the Euroregion Galicia and Minho: preliminary results
Researchers assessed microplastic contamination in agricultural soils across the Euroregion Galicia-Norte de Portugal, identifying distribution patterns and potential impacts on soil health. Agricultural practices involving plastic mulching were identified as the primary local source of soil microplastic contamination.
Microplastic in long-term soil monitoring: first spatial and temporal data on plastics in agricultural topsoils
By analysing archived soil samples from a long-term German monitoring programme spanning up to 16 years, researchers confirmed that microplastic contamination (mainly polyethylene and synthetic rubber) is widespread and long-standing in agricultural topsoils, with unexpected hotspots also found in forest and grassland sites. The study demonstrates that archived soil samples can be used to retrospectively track plastic pollution history in terrestrial environments.
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.

This review summarizes what is known about microplastic contamination in soils worldwide, covering detection methods, sources, and potential risks. Microplastics are found in soils on every continent studied, though research in Africa, South America, and Oceania remains scarce. The review highlights that microplastics accumulate in soil over time and can interact with other pollutants, potentially affecting soil health and the safety of food crops.
Impact assessment of microplastics in agricultural soils of the Euroregion Galicia and Minho: preliminary results
