ClearLarge 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.

Researchers used satellite data to track where and when farmers applied plastic mulch on agricultural fields in a European region from 2017 to 2021, finding that silage maize and asparagus fields most frequently used plastic mulch. Their analysis also revealed that 70% of maize plots used plastic mulch four or more years in a row, raising concerns about long-term plastic accumulation in agricultural soils.
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.
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.
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.
Potential sources and occurrence of macro-plastics and microplastics pollution in farmland soils: A typical case of China
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.
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.
Impact of plastic film mulching on microplastic in farmland soils in Guangdong province, China
Researchers surveyed farmland in Guangdong, China's largest economic province, to determine how much plastic mulch film contributes to soil microplastic pollution. They found that fields using plastic mulch had significantly higher microplastic levels than those without, and the contamination correlated with years of mulch use. The study helps clarify the direct agricultural contribution to soil microplastic pollution in regions with many overlapping pollution sources.
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.
Abundance and characteristics of microplastics in soils with different agricultural practices: Importance of sources with internal origin and environmental fate
Microplastic abundance and characteristics were examined in soils representing four agricultural practice types in Chinese farmland to evaluate the influence of land use on plastic particle accumulation. Microplastic concentrations and polymer types varied by agricultural practice, with plastic mulch film use and irrigation water source as key drivers of farmland soil contamination.
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.
