ClearEffects of different mulch materials on the photosynthetic characteristics, yield, and soil water use efficiency of wheat in Loess tableland
Not relevant to microplastics — this agricultural study compares different mulching materials (including plastic film) on wheat yield and water use efficiency in the Loess Plateau of China, with no focus on microplastic pollution from plastic mulch.
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.
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.
Effects of Mulching on Maize Yield and Evapotranspiration in the Heihe River Basin, Northwest China
This study examined how plastic film mulching affects maize yield and water use in northwest China's Heihe River Basin, finding that mulching increases yields and reduces evaporation. However, widespread plastic mulch use is also a major source of microplastic pollution in agricultural 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.
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.
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.
The effects of biodegradable mulch film on the growth, yield, and water use efficiency of cotton and maize in an arid region
Researchers compared biodegradable and conventional plastic mulch films in Chinese agriculture, finding that biodegradable films improved water use efficiency and crop yield comparably to conventional plastic while reducing long-term plastic accumulation in soil. Degradable mulch films represent a promising strategy to reduce agricultural microplastic pollution.
Distinct microplastic distributions in soils of different land-use types: A case study of Chinese farmlands
Microplastic distribution across six types of farmland land use was surveyed from soils in five Chinese provinces to determine how agricultural practices shape soil microplastic contamination. The study found that microplastic abundance varied significantly by land-use type, with plastic mulch film use and irrigation practices as key contributing factors.
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.
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.
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.
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.
Plastic mulch film induced soil microplastic enrichment and its impact on wind-blown sand and dust
Field experiments in semi-arid northern China showed that plastic mulch film use significantly enriched microplastics in surface soils compared to unfilmed plots, and that wind-blown sand and dust from mulched farmland transported microplastics to surrounding environments.
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.
Distribution and weathering characteristics of microplastics in paddy soils following long-term mulching: A field study in Southwest China
Researchers investigated microplastic distribution in paddy soils following long-term plastic film mulching in Southwest China, finding that ten years of continuous mulching significantly increased filmy microplastic accumulation and that weathering altered the chemical properties of these particles.
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.
