ClearTime Series approach to map areas of Agricultural Plastic Waste generation
Researchers applied a time-series remote sensing approach to map the spatial distribution of agricultural plastic waste generation across extensive agricultural landscapes, using satellite imagery to detect plastic-mulched farmlands and other agri-plastics to address the lack of comprehensive plasticulture data needed for effective waste management and land-use policy.
Macro- and microplastic accumulation in soil after 32 years of plastic film mulching
Researchers quantified plastic accumulation in an agricultural field after 32 continuous years of plastic mulch film use. They found roughly 10 times more macroplastic fragments in fertilized plots than non-fertilized plots, likely because plant roots and stems became entangled with the film making removal difficult. The study found that plastic mulch contributed 33% to 56% of total microplastics detected down to one meter of soil depth, demonstrating substantial long-term accumulation from agricultural plastic use.
Plastic mulching in agriculture. Trading short-term agronomic benefits for long-term soil degradation?
This study examined plastic mulch use in agriculture, arguing that short-term crop benefits come with long-term costs as mulch fragments accumulate in soil as microplastics and disrupt soil structure, biology, and water dynamics.
New Workflow of Plastic-Mulched Farmland Mapping using Multi-Temporal Sentinel-2 data
Researchers used multi-temporal satellite imagery to map plastic-mulched farmland in China, providing a tool for monitoring the environmental risk of agricultural plastic use. Plastic mulch is a significant source of microplastic contamination in agricultural soils when film residues break down over time.
Large Scale Agricultural Plastic Mulch Detecting and Monitoring with Multi-Source Remote Sensing Data: A Case Study in Xinjiang, China
Satellite imagery was used to monitor plastic mulch film coverage across large agricultural areas in China, mapping both spatial extent and temporal changes. Accurately tracking plastic mulch use is important because agricultural film residues are a major source of microplastic contamination in farmland soils.
Duration- and area-dependent influences of plastic film mulch on soil microplastics abundance
Researchers conducted a field campaign combined with remote sensing to investigate how the duration and coverage area of plastic film mulching affect microplastic abundance in agricultural soils in northern China's agro-pastoral ecotone, finding that microplastic concentrations ranged from 41.7 to 787.5 items per kilogram and positively correlated with mulching duration.
Consequences of 33 Years of Plastic Film Mulching and Nitrogen Fertilization on Maize Growth and Soil Quality
Researchers found that after 33 years of continuous plastic film mulching, residual microplastics in soil persisted even after mulching stopped, though soil moisture and crop yields were still influenced by the legacy effects of long-term mulch use and nitrogen fertilization.
Mapping of Agricultural Plastics Pollution in Soil: case study of Italy, France and Norway
Researchers developed an atlas quantifying and localizing agricultural plastic waste in Italy, France, and Norway, finding that plastic mulch films and other agricultural plastics accumulate in soils and generate microplastic contamination that varies significantly by crop type, climate, and waste management practices.
Plastic film residues on cropland: monitoring soil contamination through optical remote sensing
Researchers used optical remote sensing to monitor plastic film residues on agricultural cropland, demonstrating that satellite-based methods can detect surface plastic contamination across large areas. The study provides a scalable approach for tracking agricultural plastic residues — a major secondary microplastic source in soils — without the labor intensity of field sampling.
Large scale detection of plastic covered crops using multispectral and SAR satellite data
Researchers used satellite imagery combining optical and radar data to detect large-scale plastic covering of agricultural crops across wide geographic areas. The remote sensing approach could help monitor plasticulture practices and track the potential for plastic debris to enter nearby ecosystems.
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.
Exploring the Occurrence Characteristics of Microplastics in Typical Maize Farmland Soils With Long-Term Plastic Film Mulching in Northern China
A survey of 225 soil samples from maize farmland with long-term plastic film mulching in northern China found widespread microplastic contamination, with abundance, distribution, and polymer composition reflecting the history of film use and agricultural management practices.
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.
Characteristics of microplastics in dryland soils after long‐term film mulching and the effect of cropping type in western Liaoning Province, China
Fields in a semi-arid region of China that had been covered with agricultural plastic film for over a decade showed significant microplastic accumulation in the soil, with fragment shapes dominating and concentrations varying by crop type. Different crops influenced both the abundance and characteristics of microplastic particles, likely due to differences in tillage, root activity, and film use patterns. This study adds to growing evidence that agricultural plastic mulching is a major driver of farmland microplastic pollution with potential consequences for soil health and crop safety.

Impact of Plastic Mulching on Microplastic Contamination in Mountainous Agricultural Soils
A study on plastic mulch use in agriculture found that it significantly increases microplastic contamination in soils, with particle concentrations rising with cumulative years of mulch application. The findings reinforce concerns about plastic mulching as a major contributor to agricultural soil microplastic pollution.
Vertical distributions of microplastics in long-term mulched soils and their potential impacts on soil properties and microbial diversity
Microplastic concentrations were measured at different depths in agricultural soils that had been mulched with plastic film over many years, finding vertical stratification with higher concentrations near the surface. Long-term plastic mulching leads to progressive accumulation of microplastics throughout the soil profile.
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.
Are agricultural plastic covers a source of plastic debris in soil? A first screening study
Agricultural plastic covers made from polyethylene and polypropylene were assessed for their potential to fragment and contribute microplastics to underlying soil in a screening study, with early results suggesting partial breakdown during field use. The study provides preliminary evidence that agricultural covers are a source of soil microplastic contamination beyond just mulch films.
Microplastic Accumulation and Soil Quality Changes Under Varying Plastic Mulching Durations in the Mediterranean Region
Researchers studied microplastic accumulation in agricultural soils across 15 sites in Türkiye that had used plastic mulching for 5, 10, and 30 years. They found that longer mulching durations led to significantly higher microplastic concentrations, with soil quality declining as plastic particles accumulated. The study suggests that decades of plastic mulch use degrades soil health by altering physical, chemical, and biological properties.
