Microplastics distribution and microbial community characteristics of farmland soil under different mulch methods
This study compared microplastic distribution and soil microbial community structure in farmland soils under different plastic film mulching methods including no mulch, biodegradable film, and conventional polyethylene film. Mulching method significantly altered both microplastic abundance and microbial diversity in the top soil layer.
Microplastics pollution in agricultural farms soils: preliminary findings from tropical environment (Klang Valley, Malaysia)
Microplastic pollution was documented for the first time in agricultural soils from four farms in Malaysia's tropical Klang Valley, with concentrations of 2.1-3.4 particles per kg and plastic nets, mulching films, and unmanaged waste as the primary sources.

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.
Contamination of microplastics in greenhouse soil subjected to plastic mulching
This study quantified microplastic accumulation in greenhouse soils under different durations of plastic mulching, finding that longer mulching periods significantly increased MP concentrations in both topsoil and subsoil. Soil physicochemical properties were associated with MP contamination levels, suggesting soil type and organic matter influence MP retention.
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.
Microplastics pollution modulated by farming regimes under multi-scenarios
Microplastic concentrations in agricultural soils were found to vary with farming regimes, with certain practices under mulching leading to higher accumulation. The study highlights how common agricultural methods contribute to soil microplastic pollution and supports calls for better plastic mulch management.
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.
Microplastics in agricultural soils on the coastal plain of Hangzhou Bay, east China: Multiple sources other than plastic mulching film
Researchers analyzed agricultural soils from the Hangzhou Bay coastal plain and found microplastic concentrations of 571 pieces/kg in mulched soils versus 263 pieces/kg in non-mulched soils, with irrigation water identified as an additional major source alongside mulch films. The findings point to multiple input pathways for microplastic accumulation in Chinese farmland soils.
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.
Occurrence and distribution of microplastics in coastal plain soils under three land-use types
Microplastic abundance and polymer composition were characterized in farmland, plantation, and orchard/secondary forest soils from 33 sites on the east China coastal plain. Farmland soils had significantly higher microplastic abundances than forest soils, with agricultural plastic mulching identified as the primary source of the dominant polyethylene film fragments.
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.
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.
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.

Microplastics abundance associated with farmland use types and the impact on soil microbial communities: A case study in Southern China
Researchers surveyed microplastic contamination across orchard, paddy field, and vegetable field soils in Southern China and analyzed how it affected soil microbial communities. They found microplastic levels ranging widely across sites, with very small particles under 30 micrometers being most common, and identified 32 different polymer types. The study shows that farmland use type and agricultural practices like plastic mulching significantly influence both the amount and type of microplastic contamination in soils.
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.
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. Agricultural film mulch significantly increased soil microplastic levels, especially in orchards, while higher population density and economic activity correlated with increased contamination across all land types.
