ClearNew 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.
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.
Time 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.
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.
Cropland Microplastics in Xinjiang: Unveiling Distribution and Impact of Mulching Film Residues
This study assessed microplastic distribution and the contribution of agricultural mulching film residues across croplands in Xinjiang, China, finding widespread polyethylene microplastic contamination that correlates with mulch film use intensity and poses risks to soil health and food safety.
Occurrence status of microplastics in main agricultural areas of Xinjiang Uygur Autonomous Region, China
Agricultural soils in Xinjiang, China, were surveyed for microplastic contamination, revealing widespread presence in major farming regions where plastic mulch films and irrigation systems are heavily used. The study provides one of the first regional-scale assessments of microplastic pollution in this important agricultural area.
Occurrence characteristics, source analysis, and risk assessment of microplastics in agricultural soils: A case study on Shihezi Reclamation Area, Xinjiang, China
Microplastic occurrence was characterized in agricultural soils of the Shihezi Reclamation Area, Xinjiang — a region with decades of plastic film mulching — finding high-density PE and PP fragments as dominant types, with mulch film degradation as the primary source.
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.
Identification of Plastic Mulch in Cotton Fields Using UAV-Based Hyperspectral Data and Deep Learning Semantic Segmentation
Plastic mulch film is widely used in agriculture to improve crop yields, but residual plastic in fields contributes to soil microplastic contamination, and identifying where it remains after harvest is difficult at scale. This study used drone-mounted hyperspectral cameras combined with deep-learning image analysis to map plastic mulch coverage in cotton fields in China, achieving up to 80% accuracy in distinguishing plastic from soil and crop canopy. Accurate mapping of residual mulch is a critical first step toward targeted plastic removal and reducing the flow of agricultural microplastics into soil and water.
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.
Contribution of mulch film to microplastics in agricultural soil and surface water in China
Researchers developed a framework to quantify how much agricultural mulch film contributes to microplastic contamination in farmland soil and surface water in China, measuring the ratio of mulch-derived particles to total microplastics from all sources.

Researchers combined field sampling and remote sensing to assess microplastic pollution in agricultural soils across three Indian locations, finding microplastics in both surface and subsurface layers and correlating pollution levels with land use patterns detectable by satellite imagery.
Microplastic contamination in cotton soils following long-term mulching: A field study for the Xinjiang production and construction corps in China
Researchers investigated microplastic accumulation across agricultural soils in Xinjiang, China — a major mulch film use region — finding that microplastic abundance positively correlates with mulching duration and that geographical and social factors drive north-south differences in contamination levels.
Microplastic Accumulation in Agricultural Soils with Different Mulching Histories in Xinjiang, China
Researchers found that microplastic accumulation in agricultural soils of Xinjiang, China increases significantly with mulching history, with fields mulched for over 20 years containing substantially more microplastics across all soil layers.
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.
Microplastics in arid soils: Impact of different cropping systems (Altay, Xinjiang)
Researchers investigated microplastic contamination in farmland soils in an arid region of China, finding extremely high concentrations averaging over 52,000 particles per kilogram of soil. Polyethylene from plastic mulch film accounted for over 90% of the microplastics, with fields growing tall crops like sunflower and maize showing more contamination than potato fields. The study demonstrates that agricultural plastic mulch use is a major source of soil microplastic pollution, particularly in arid farming regions.
