Microplastics in Agricultural Soils: Sources, Fate, and Interactions with Other Contaminants
This review examines how microplastics enter farmland through irrigation, fertilizers, and plastic mulch, and how long-term farming practices affect their spread and aging in soil. The paper highlights that microplastics can either increase or decrease the toxicity of co-existing pollutants like pesticides and heavy metals depending on how strongly each contaminant binds to soil versus plastic particles.
Microplastic contamination in the agricultural soil—mitigation strategies, heavy metals contamination, and impact on human health: a review
This review examines how microplastics contaminate agricultural soil through plastic mulch, irrigation water, and fertilizers, then alter soil chemistry, harm beneficial microorganisms, and reduce crop productivity. The authors highlight that microplastics can accumulate in crops and enter the human food chain, posing risks to food safety and human health, particularly through daily food and water consumption.
Microplastics in agroecosystem – effects of plastic mulch film residues on soil-plant system

Both types of mulch film residues are found to have negative effects on the soil-plant system, raising questions about the environmental safety of biodegradable plastic alternatives.
Microplastics in Agriculture- a Review
This review examines the growing presence of microplastics in agricultural environments, covering their sources from plastic mulch films and irrigation water, their effects on soil health and crop quality, and the implications for food safety and sustainable agriculture.
Microplastic Pollution in Terrestrial Ecosystems and Its Interaction with Other Soil Pollutants: A Potential Threat to Soil Ecosystem Sustainability
This review examines microplastic pollution in soils and how plastic particles interact with other pollutants like pesticides and heavy metals. About 80% of all plastic waste produced in the last 75 years has ended up in landfills or the environment, where it breaks into microplastics that alter soil health and contaminate crops. The combined effects of microplastics with other soil pollutants could threaten food safety and ultimately human health.
Environmental health implications of plastic use in agriculture
This review discusses the environmental health implications of plastic use in agriculture, including soil microplastic accumulation from mulch films, microplastic uptake by crops, and potential entry into the food chain. The authors recommend shifting toward biodegradable alternatives and tightening regulations on agricultural plastic disposal.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
This systematic review examines how plastic mulch films used in agriculture break down over time and release microplastics into farm soil. The films improve crop growth but create lasting environmental damage as plastic fragments accumulate and alter soil properties. The findings underscore the importance of developing truly biodegradable alternatives to protect farmland from microplastic pollution.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
This systematic review traces the full lifecycle of plastic mulch films used in farming, from application to breakdown in soil. While these films boost crop yields, they leave behind persistent residues that fragment into microplastics, potentially contaminating soil and groundwater. The review highlights the need for biodegradable alternatives to reduce long-term microplastic accumulation in agricultural land.
Plastics in soils: impacts on agriculture and food
This work reviews the impacts of plastic pollution in soils on agricultural productivity and food safety, examining how plastic particles and associated chemicals affect soil health, crop growth, and food quality. The publication is part of the international scientific literature on plastic contamination of agricultural systems.
Influence on the processes of retention and transport of pesticides and ecotoxicity of microplastics in a tropical soil
Researchers investigated how high-density polyethylene microplastics from agricultural mulch films affect the behavior of three pesticides in tropical soil, finding that microplastics altered pesticide sorption, transport, and leaching while also increasing ecotoxicological effects on earthworms.
Microplastic contamination in agricultural soils from mulch films and organic amendments: Transformation mechanism, soil-Biota toxicity, and future perspectives
This review examines how agricultural soils are becoming increasingly contaminated with microplastics from plastic mulch films and organic amendments like compost, with land-based contamination being 4 to 23 times higher than in water. Microplastics in farmland can harm soil organisms, disrupt soil structure, and enter the food chain through crops, posing potential risks to human health.
Polyethylene film incorporation into the horticultural soil of small periurban production units in Argentina
Researchers surveyed Argentine horticultural soils and found plastic film residues covering 10% of the soil area, then demonstrated in laboratory experiments that polyethylene film strongly adsorbs pesticides (up to 2,284 µg per gram of plastic versus 32 µg per gram of soil), suggesting plastic mulch residues act as pesticide reservoirs that may alter contaminant fate in agricultural fields.

Behavior of microplastics and plastic film residues in the soil environment: A critical review
This critical review examines the behavior and fate of microplastics in soil environments, particularly in agricultural land where plastic mulch films and biosolid applications have left a legacy of contamination. Researchers note that many soils now contain an estimated 50 to 250 kilograms of plastic residue per hectare, but the difficulty of extracting and measuring plastic particles from soil has limited our understanding of the risks. The study calls for improved methods to assess whether soil-borne microplastics can migrate to groundwater, air, and the human food chain.
Macro- and microplastic accumulation in soil after 32 years of plastic film mulching
Researchers quantified plastic accumulation in an agricultural field after 32 continuous years of plastic mulch film use. They found roughly 10 times more macroplastic fragments in fertilized plots than non-fertilized plots, likely because plant roots and stems became entangled with the film making removal difficult. The study found that plastic mulch contributed 33% to 56% of total microplastics detected down to one meter of soil depth, demonstrating substantial long-term accumulation from agricultural plastic use.
