ClearEffects of residual mulching films with different mulching years on the diversity of soil microbial communities in typical regions
Researchers examined four cotton fields in Xinjiang, China with varying polyethylene mulch film histories (0-25 years) using high-throughput sequencing to assess how residual film and microplastics affect soil microbial communities. They found that short-term mulching (0-10 years) increased microbial diversity while continuous 25-year mulching significantly decreased bacterial diversity, with Proteobacteria and Ascomycetes dominating, and residual film accumulation reducing bacterial community diversity without significantly impacting fungal diversity.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.

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.
Evaluating the Impact of Traditional and Biodegradable Mulch Film Residues on Heavy Metal Dynamics and Maize Productivity: Insights from Arbuscular Mycorrhizal Fungi Community Analysis
Researchers compared the long-term effects of traditional polyethylene and biodegradable mulch film residues on soil properties, heavy metal uptake in maize, and beneficial soil fungi communities. Traditional mulch residues increased the accumulation of arsenic and cadmium in maize roots while altering soil chemistry, whereas biodegradable mulch residues also affected fungal communities but in different ways. The study suggests that neither type of mulch film is without environmental consequence, and that their residues can influence both crop safety and soil microbial health.
Plastic Film Residue Reshaped Protist Communities and Induced Soil Nutrient Deficiency Under Field Conditions
Researchers conducted a field experiment to examine how long-term plastic mulch film residues affect soil microorganisms and nutrient cycling. They found that plastic residues significantly reduced the diversity of protist communities, which play key roles in soil health, and led to deficiencies in soil moisture, nitrogen, and phosphorus. The study underscores that agricultural plastic waste creates lasting negative effects on soil ecosystems well beyond its intended use.
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.
Rice Cultivation under Film Mulching Can Improve Soil Environment and Be Beneficial for Rice Production in China
This review examines the benefits and drawbacks of growing rice under plastic film mulch in China, which improves water efficiency and yield but contributes to microplastic contamination of agricultural soil. While degradable films and organic fertilizers offer partial solutions, long-term plastic residue in farmland remains a concern. The study highlights the tension between agricultural productivity and the risk of microplastic pollution entering the food supply through soil.
Effects of mulching film on soil microbial diversity and community of cotton
Researchers compared how traditional polyethylene (PE) plastic mulch and biodegradable PBAT mulch affect soil microbes in Chinese cotton fields. PBAT mulch significantly altered the diversity of soil fungi — particularly boosting Gibellulopsis — while neither type of mulch strongly affected bacterial diversity, suggesting biodegradable mulch changes the soil ecosystem in ways that need further study.
The layout measures of micro-sprinkler irrigation under plastic film regulate tomato soil bacterial community and root system
Researchers investigated how different layout measures of micro-sprinkler irrigation under plastic film affect soil bacterial community structure and root system development in tomato crops in Northwest China. The L1C2 treatment produced the most stable bacterial community and best root morphological development, positively contributing to increased tomato yield and supporting water-saving production practices.
Effect of Long-Term Biodegradable Film Mulch on Soil Physicochemical and Microbial Properties
Long-term use of biodegradable mulch film was compared to conventional plastic and no-mulch controls in terms of soil physical, chemical, and microbial properties, with results showing that biodegradable mulch altered soil structure and microbial diversity in ways differing from both conventional plastic and bare soil. The findings raise questions about the cumulative effects of biodegradable plastic residues on agricultural soil health.
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.

Characteristics of microplastics and their abundance impacts on microbial structure and function in agricultural soils of remote areas in west China
Researchers found that agricultural soils in remote western China using plastic mulch film had about four times more microplastics than fields without it, mostly tiny polyamide fragments under 50 micrometers. The microplastics changed the diversity and function of soil bacteria, including boosting organisms linked to organic matter breakdown. These microbial shifts could affect soil health and potentially increase health risks from crops grown in contaminated soil.

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.
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.
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.
