This review examines plastic pollution in Chinese farmland soils, finding that agricultural practices like mulch film use and sewage sludge application are major sources of both macro- and microplastics that accumulate over time.
Polymers Use as Mulch Films in Agriculture—A Review of History, Problems and Current Trends
This review traces the history of plastic mulch films in agriculture, from their widespread adoption for moisture retention and weed control to growing concerns about soil contamination. Researchers found that while polyethylene mulch is highly effective, its accumulation in farmland creates long-term pollution and health risks. The study examines emerging biodegradable alternatives and new regulations aimed at reducing agricultural plastic waste.
Revealing the Full Picture of Agricultural Plastic Legacy Pollution: Toward “Zero‐Leakage” Management in Chinese Farmlands
This review examines the legacy of agricultural plastic mulch film pollution in Chinese farmlands, where China consumes approximately 68% of global mulch film production, leading to persistent residue accumulation and microplastic contamination. The authors propose a 'zero-leakage' management framework to address the full spectrum of plastic pollution across different environmental compartments in agricultural settings.
Agricultural plastic mulching as a source of microplastics in the terrestrial environment
Researchers analyzed 384 soil samples from 19 Chinese provinces and found that macroplastic fragments were concentrated in agricultural fields with plastic mulch film use, providing large-scale field evidence linking agricultural mulching to terrestrial plastic contamination.
The abundance, characteristics and distribution of microplastics (MPs) in farmland soil—Based on research in China
This review analyzed microplastic contamination in farmland soil across China and found that fertilizer use and plastic mulch film are the biggest contributors, increasing soil microplastic levels by 170% and 232% respectively. The most common types found were polyethylene and polypropylene fragments and fibers. These findings are concerning because microplastics in farm soil can be taken up by crops and enter the human food supply.
Rice Cultivation under Film Mulching Can Improve Soil Environment and Be Beneficial for Rice Production in China
This review examines the benefits and drawbacks of growing rice under plastic film mulch in China, which improves water efficiency and yield but contributes to microplastic contamination of agricultural soil. While degradable films and organic fertilizers offer partial solutions, long-term plastic residue in farmland remains a concern. The study highlights the tension between agricultural productivity and the risk of microplastic pollution entering the food supply through soil.
Microplastics in agricultural soils in China: Sources, impacts and solutions
This review examines microplastic contamination in Chinese agricultural soils, finding abundances ranging from about 5 to over 40,000 items per kilogram depending on location. The study identifies plastic mulching films as the most significant source, followed by abandoned greenhouses and organic fertilizers, and recommends sustainable agronomic practices to reduce soil microplastic pollution.
Occurrence and characteristics of microplastics in soils from greenhouse and open-field cultivation using plastic mulch film
Researchers surveyed microplastic contamination in agricultural soils across three regions in China, comparing greenhouse and open-field cultivation that uses plastic mulch film. They found that microplastic abundance varied significantly by region and that the type of mulching practice accounted for over 34% of the variation in microplastic composition. The study provides important baseline data on how plastic film use in farming contributes to soil microplastic pollution.
The agricultural plastic paradox: Feeding more, harming more?
This review examines the trade-off between the agricultural benefits of plastic film mulch, which helps feed an estimated 85 million additional people in China alone, and the growing microplastic contamination it causes in farmland soils. Researchers found that current studies on the effects of mulch-derived microplastics use inconsistent methods and often unrealistically high concentrations, making it difficult to assess the true risks. The study calls for standardized research approaches to better understand whether the agricultural benefits of plastic mulch outweigh its environmental costs.
Potential sources and occurrence of macro-plastics and microplastics pollution in farmland soils: A typical case of China
This study provides the first comprehensive survey of plastic pollution in Chinese farmland soil, analyzing data from 163 publications covering 728 sites. The average microplastic abundance was 4,537 particles per kilogram of dry soil, with agricultural plastic films and organic waste being the biggest sources. Since China is the world's largest user of agricultural plastics, these findings highlight how farming practices can lead to significant microplastic contamination of the soil that grows our food.

The study proposes targeted prevention measures to protect the ecological environment and ensure safe vegetable production in the region.
Plastic Mulch Films in Agriculture: Their Use, Environmental Problems, Recycling and Alternatives
This review examines how plastic mulch films used in farming break down into microplastics and nanoplastics that contaminate soil, harm soil organisms, and can enter the human body through the food chain. While developed countries are making progress with recycling and biodegradable alternatives, the health effects of nanoplastics from agricultural plastic remain largely unknown. Better collection, recycling, and alternative materials are needed to reduce this growing source of plastic pollution.
Distinct microplastic distributions in soils of different land-use types: A case study of Chinese farmlands
Microplastic distribution across six types of farmland land use was surveyed from soils in five Chinese provinces to determine how agricultural practices shape soil microplastic contamination. The study found that microplastic abundance varied significantly by land-use type, with plastic mulch film use and irrigation practices as key contributing factors.
Distribution of microplastics in mulched soil in Xinjiang, China
Researchers measured microplastic distribution in plastic-mulched farmland soils in Xinjiang, China, finding that plastic particles concentrate in the top soil layer where mulch films fragment. The dominant polymer found was polyethylene, consistent with the plastic mulch films widely used in agriculture across the region.
Temporal and Spatial Distribution of Residual Film in Soil Profile under Continuous Film Mulching
Eight years of continuous plastic mulch film use on Chinese farmland steadily increased the number of plastic fragments in soil, with smaller pieces migrating progressively deeper over time even as total plastic mass slowly declined. The finding that fragments accumulate below 10 cm — beyond the reach of most tillage — highlights how agricultural microplastic pollution can become entrenched and difficult to remediate.
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.
Effects of agricultural land types on microplastic abundance: A nationwide meta-analysis in China
Meta-analysis of 321 observations across Chinese agricultural soils found that vegetable-growing soils had the highest microplastic contamination, followed by orchards, cropland, and grassland.
