Degradable mulch films represent a promising strategy to reduce agricultural microplastic pollution.
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.
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.
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.
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.
Macro- and micro- plastics in soil-plant system: Effects of plastic mulch film residues on wheat (Triticum aestivum) growth
Researchers studied how plastic mulch film residues, both conventional polyethylene and biodegradable types, affect wheat growth when mixed into soil. They found that both macro- and micro-sized plastic residues negatively impacted plant growth above and below ground, with effects varying depending on the plastic type and the presence of earthworms. The study highlights that agricultural plastic residues left in soil can meaningfully affect crop development and soil ecosystem health.
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.
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.

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.
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.
The persistently breaking trade-offs of three-decade plastic film mulching: Microplastic pollution, soil degradation and reduced cotton yield
A study of cotton fields in northwest China with 3-32 years of continuous plastic mulch use found that microplastic abundance in soil increased exponentially with mulching duration, while soil physical properties degraded and cotton root traits and yields declined in heavily mulched plots. The results challenge the assumed economic trade-off of plastic mulching, suggesting decades of cumulative MP pollution eventually costs more in yield than it provides in early-season benefits.

Replacing conventional plastic mulch with biodegradable alternatives could reduce microplastic accumulation in agricultural soils.
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.
