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.
Is mulch film itself the primary source of meso- and microplastics in the mulching cultivated soil? A preliminary field study with econometric methods
A field study examined whether mulch films were the primary source of meso- and microplastics in mulched agricultural soils using econometric methods to compare plastic-mulched and non-mulched fields, finding that while mulch contributed to soil plastic loads, it was not the sole source. The study challenges the assumption that plastic mulch is always the dominant microplastic source in farmed soils.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
This systematic review examines how plastic mulch films used in agriculture break down over time and release microplastics into farm soil. The films improve crop growth but create lasting environmental damage as plastic fragments accumulate and alter soil properties. The findings underscore the importance of developing truly biodegradable alternatives to protect farmland from microplastic pollution.

Agricultural plastics as a potential threat to food security, health, and environment through soil pollution by microplastics: Problem definition
This paper investigates how agricultural plastics -- like mulch films, greenhouse covers, and silage wraps -- break down in soil and release micro- and nanoplastic particles that can contaminate crops. The research ranks different agricultural plastic products by their risk of generating soil pollution, raising concerns about microplastics entering the human food supply through farm-grown produce.
Impact of plastic mulching as a major source of microplastics in agroecosystems
This review examines how plastic mulch films used in agriculture break down into microplastics over time, making farmland a major source of soil microplastic pollution. The accumulated microplastics can alter soil properties, affect plant growth, and be taken up by crops that humans eat. The study highlights the need for better end-of-life management of agricultural plastics and more research on how farm-sourced microplastics enter the food chain.
Macro and microplastics in agricultural soils after use of conventional and biodegradable plastics
Researchers sampled 38 agricultural fields where different plastic products had been used — conventional polyethylene mulching films, polypropylene weed fabrics, biodegradable PBAT mulching films, frost covers, and oxo-degradable films — analyzing both macro and microplastics in soil at varying size fractions. They found plastic particles from all film types present in soils, with biodegradable and oxo-degradable films producing detectable microplastics, raising concerns about all agricultural plastic categories.
Microplastics in Agricultural Soil and Their Impact: A Review
This review examines how microplastics accumulate in agricultural soils through sources like plastic mulch films, sewage sludge, and fertilizers. The particles can affect soil structure, microbial activity, and plant health, with common polymer types including polyethylene, polypropylene, and polystyrene found across farmland. The study emphasizes the need for better plastic waste management to protect agricultural ecosystems from growing microplastic contamination.
Origin, Occurrence and Threats of Microplastics in Agricultural Soils: A Comprehensive Review
This comprehensive review examines how microplastics enter and accumulate in agricultural soils through plastic mulch films, sewage sludge, and fertilizers. Researchers found that polypropylene and polyethylene are the dominant polymers in farmland soils, and that microplastics negatively affect soil microbial communities, harm soil invertebrates, and can induce oxidative stress and cell damage in plants.
Plastic mulching, and occurrence, incorporation, degradation, and impacts of polyethylene microplastics in agroecosystems
This review examines how plastic mulch films used in agriculture break down into polyethylene microplastics and what happens to them in farm ecosystems. Researchers describe how microorganisms colonize these particles and can eventually break down the plastic molecules, but also how the microplastics alter soil microbial communities and nutrient cycling. The study highlights plastic mulching as a major source of microplastic contamination in agricultural soils worldwide.
