Consequences of 33 Years of Plastic Film Mulching and Nitrogen Fertilization on Maize Growth and Soil Quality
Researchers found that after 33 years of continuous plastic film mulching, residual microplastics in soil persisted even after mulching stopped, though soil moisture and crop yields were still influenced by the legacy effects of long-term mulch use and nitrogen fertilization.
Distribution of soil water and nitrate in furrow irrigation under different plastic mulch placement conditions for a maize crop: Field and modelling study
This study examined how the placement of plastic mulch in furrow irrigation systems affects soil water distribution and nitrate leaching in maize fields. While plastic mulch improves crop yields, its fragmentation over time is a recognized source of agricultural microplastic pollution.
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.
The Effects of Biodegradable Mulch Film on the Growth, Yield, and Water Use Efficiency of Cotton and Maize in an Arid Region
Biodegradable mulch film maintained crop growth and water use efficiency comparable to conventional polyethylene film in Chinese cotton and maize fields for the first 60 days, then began to degrade. Replacing conventional plastic mulch with biodegradable alternatives could reduce microplastic accumulation in agricultural soils.
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.
Macro and microplastics in agricultural soils after use of conventional and biodegradable plastics
Researchers sampled 38 agricultural fields where conventional polyethylene mulching films, polypropylene weed fabrics, biodegradable PBAT films, and frost covers had been used, quantifying macro- and microplastic contamination in soils to assess how different agricultural plastic products contribute to soil plastic pollution.
Agricultural plastic films reshape soil microplastic distribution, nitrogen cycle and ecological risks in facility agriculture
Researchers compared microplastic characteristics in protected agriculture systems and traditional farmland soils in China, finding significantly higher microplastic abundance in mulched farmland and documenting correlations between microplastic presence and altered soil nitrogen cycling and heavy metal distribution.
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.
Impact of Management Strategies on Reducing of Mulching Film Residues Pollution in Arid Regions
Researchers examined the impact of different management strategies — including increased polyethylene film recycling rates and adoption of biodegradable mulch films — on reducing mulching film residue pollution in arid agricultural regions. The study found that combining recycling incentives with biodegradable film adoption significantly reduced soil plastic accumulation, supporting sustainable agricultural development in water-limited dryland farming systems.
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.
Effects of Future Climate Change on Spring Maize Yield and Water Use Efficiency under Film Mulching with Different Materials in the LOESS Plateau Region of China
Researchers used the DNDC biogeochemical model to evaluate effects of future climate change (2021-2100) on spring maize yield and water use efficiency under polyethylene film mulching and biodegradable film mulching in China's Loess Plateau, finding that biodegradable films can maintain yields while reducing plastic pollution under projected warming and increased rainfall.
Effects of Different Mulch Types on Farmland Soil Moisture in an Artificial Oasis Area
Not relevant to microplastics — this study compares how different mulch materials (including conventional polyethylene plastic films) affect soil moisture retention in an arid farming region of China, focusing on water management rather than plastic fragmentation or microplastic contamination.
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.
Microplastics in agricultural soils: Extraction and characterization after different periods of polythene film mulching in an arid region
Researchers developed a new method to extract microplastics from agricultural soil and found that fields mulched with plastic film for 30 years had the highest microplastic concentrations, at 40 mg per kilogram of soil, with particle size decreasing as the years of mulching increased. The study highlights the long-term accumulation of microplastics in soils under continuous plastic film agriculture.
Environmental risk of multi-year polythene film mulching and its green solution in arid irrigation region
Researchers found that 19 years of polythene film mulching accumulated up to 2,900 microplastic particles per kilogram of soil along with elevated plasticizer concentrations, and demonstrated that biodegradable film alternatives could significantly reduce this environmental contamination.
Estimating the potential of climatic factors for global generation of microplastics from agricultural plastic films
Researchers combined national agricultural plastic film usage data with emission factor models and Monte Carlo simulations to estimate the global generation of microplastics from agricultural films. The resulting estimates highlight the large but uncertain scale of this contamination source for soil and food security.
