Greenhouse farming as a source of macroplastic and microplastics contamination in agricultural soils: a case study from Southeast-Hungary
Researchers quantified macroplastic and microplastic contamination in greenhouse farmland soils in China, finding significant accumulation of polyethylene film fragments throughout the soil profile and in underlying groundwater, demonstrating that greenhouse agriculture is a substantial source of agricultural soil plastic pollution.
Management of agricultural plastic waste in Portugal to prevent microplastics
This study assessed agricultural plastic waste management practices in Portugal and their role in generating soil micro- and nanoplastics. Poor management of plastic mulches and other agricultural films was identified as a significant and preventable source of persistent soil contamination.
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.
Management of agricultural plastic waste in Portugal to prevent microplastics
Researchers examined the management of agricultural plastic waste in Portugal, assessing how mismanagement of plastics used in farming has led to soil contamination with microplastics and identifying practices that reduce plastic fragmentation and environmental release. The study found gaps between best practices and actual farm-level waste management that result in preventable plastic accumulation in agricultural soils.
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.
Vertical distribution and characteristics of soil microplastics under different land use patterns: A case study of Shouguang City, China
Researchers systematically investigated microplastic distribution across seven land use types and three soil depth layers in Shouguang City, China. The study found that greenhouse and polytunnel agricultural soils had the highest microplastic abundance, dominated by polyethylene and polypropylene film fragments, with concentrations decreasing with depth but still reaching 11-19% of total levels in the deepest layer at 40-60 centimeters.
Accumulation of microplastics in greenhouse soil after long-term plastic film mulching in Beijing, China
Researchers found that microplastic contamination in Beijing greenhouse soils increased with the duration of plastic film mulching, with abandoned greenhouses accumulating the highest levels at over 2,200 particles per kilogram of soil.
Tracking the source of microplastics in soil—an exploratory case study in peach orchards from east-central Portugal
Researchers tracked the sources and types of microplastics found in agricultural soil at peach orchards in east-central Portugal by analyzing soil, irrigation water, organic fertilizers, and atmospheric fallout. They identified microplastics from multiple entry points, including irrigation and soil amendments, with fibers and fragments being the most common shapes. The study demonstrates the need for a multi-source approach to understanding how microplastics accumulate in farmland.
Macro- and micro-plastic accumulation in soils under different intensive farming systems: A case study in Quzhou county, the North China Plain
Soil samples from six farming systems in the North China Plain showed macroplastic abundances from 0.2 to 46.8 kg/ha and microplastic concentrations up to 3.7×10⁴ items/kg, with greenhouse and mulched vegetable fields showing the highest contamination.
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.
Mapping of Agricultural Plastics Pollution in Soil: case study of Italy, France and Norway
Researchers developed an atlas quantifying and localizing agricultural plastic waste in Italy, France, and Norway, finding that plastic mulch films and other agricultural plastics accumulate in soils and generate microplastic contamination that varies significantly by crop type, climate, and waste management practices.
Quantification of macroplastic litter in fallow greenhouse farmlands: case study in southeastern hungary
A survey of fallow greenhouse farmlands in southern Hungary found an average of 434 macroplastic pieces per 100 square meters on soil surfaces, predominantly film fragments from agricultural covers. This quantification of large plastic debris matters because macroplastics are the primary source of microplastic contamination in farmland soils as they break down over time.
Microplastics Derived From Disposable Greenhouse Plastic Films and Irrigation Pipes: A Case Study From Turkey
Researchers found an average of 11.13 microplastics/kg in agricultural soils in Turkey's Adana region where disposable greenhouse plastic films and irrigation pipes are used, with one site reaching 32 microplastics/kg, linking agricultural plastic inputs directly to soil microplastic contamination.
Spatial and temporal variance of microplastics in agricultural soils
This study reviewed how microplastic concentrations in agricultural soils vary by location and over time across multiple European field sites. The findings highlight that farming practices are direct sources of soil plastic contamination, and that long-term monitoring is needed to understand accumulation trends and their effects on soil health.
Understanding the impact of microplastic contamination on soil quality and eco-toxicological risks in horticulture: A comprehensive review
This review examines how microplastic contamination in horticultural soils affects soil quality, plant health, and food safety. Microplastics alter soil structure, reduce beneficial microbial activity, and can transfer toxic chemicals to edible crops. Since horticulture provides a significant portion of the global food supply, understanding and addressing microplastic contamination in these soils is critical for protecting human health.
Plastics derived from disposable greenhouse plastic films and irrigation pipes in agricultural soils: a case study from Turkey
Researchers investigated plastic contamination in agricultural soils in Turkey where disposable greenhouse films and irrigation pipes are used. They found an average of 16.5 plastic pieces per kilogram of soil, with about 42% being microplastics, and evidence indicates that removing used plastics after the growing season significantly reduces soil contamination.

Methodological Approach for Detecting Polypropylene Microplastics in Agricultural Soil in Southern Portugal
A methodological approach was developed specifically for detecting polypropylene microplastics, one of the most common plastics in the environment. Improved polypropylene-specific detection methods help fill a gap in monitoring programs, since this polymer can be challenging to identify with general-purpose techniques.
A nationwide assessment of microplastic abundance in agricultural soils: The influence of plastic crop covers within the United Kingdom
A nationwide study of 108 agricultural sites across the United Kingdom found microplastics in all soil samples, with concentrations averaging 3,680 particles per kilogram. Fields where plastic crop covers were used had significantly higher microplastic levels than those without plastic covers. This study shows that common agricultural plastic use is a major source of soil microplastic contamination, which could ultimately affect crop quality and enter the food chain.
