ClearProcesses controlling the transportation of microplastics in agricultural soils
Researchers investigated the physical processes controlling microplastic transport through agricultural soils, examining how soil structure, water flow, bioturbation, and particle properties interact to move microplastics from surface application sites deeper into the soil profile or laterally toward aquatic systems. The study addressed the dual role of agricultural soils as both sinks and potential sources of microplastic pollution to surrounding environments.
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.
Influences of land use and depth profile on the characteristics of microplastics in agricultural soils
Researchers examined how land use and soil depth profile influence microplastic characteristics in agricultural soils, finding that wastewater and sludge application, plastic mulching, and atmospheric deposition are key sources, and that MP type and abundance vary with soil management practice and depth, highlighting the importance of vertical distribution in soil MP studies.

This review examines the accumulation of microplastics in agricultural soils from sources like plastic mulching and irrigation, discussing their effects on soil properties and crop growth, along with current bioremediation approaches for removing soil microplastics.
Microplastic in Terrestrial Ecosystems and the Soil?
This review examined the occurrence and behavior of microplastics in terrestrial ecosystems and soils, questioning how particles move through and accumulate in soils and calling for more research on land-based microplastic impacts.
Soil Pollution from Micro- and Nanoplastic Debris: A Hidden and Unknown Biohazard
This review examines what is known about the fate and properties of microplastics and nanoplastics in soil, highlighting that agricultural land acts as a long-term sink for the ~300 million tons of plastic produced annually, with major knowledge gaps in detection and ecotoxicological effects.
Microplastic contamination in soil environment – a review
This review examines the sources, transport, degradation, and ecological impacts of microplastic contamination in soil environments. The study suggests that soil acts as both a major sink for microplastics and a conduit transporting them to aquatic systems, and that microplastics can negatively affect soil organisms and biogeochemistry, underscoring the need for more research on terrestrial microplastic pollution.
Macro and microplastics in the soil: abundance, characterization, identification, and interactions under different land uses in an agricultural sub-basin
Researchers examined the abundance, characterization, identification, and interactions of macro- and microplastics in soils under different land uses within an agricultural sub-basin, assessing how land-use patterns influence plastic pollution distribution and potential interactions with the soil environment.
The extent and impacts of soil pollution by microplastics
This study examines the extent and impacts of soil pollution by microplastics, reviewing evidence of how microplastic particles accumulate in terrestrial environments and affect soil ecosystems, organisms, and agricultural systems.
Microplastics in Agricultural Soil
This book chapter surveys microplastic contamination in agricultural soils, reviewing the sources of plastic inputs, concentrations found in different farming systems, and the effects of MPs on soil properties, microbial communities, and crop yields.
Recent advances on ecological effects of microplastics on soil environment
This review summarizes recent advances in understanding the ecological effects of microplastics on soil environments. Researchers found that soils serve as major sinks for microplastics, which can alter soil properties, affect plant growth, disrupt soil microbial communities, and interact with other pollutants. The study highlights that terrestrial microplastic pollution may be even more pervasive than aquatic contamination and warrants greater research attention.
A Review on Microplastic in the Soils and Their Impact on Soil Microbes, Crops and Humans
This review examines microplastic contamination in agricultural soils, detailing how microplastic particles act as vectors for toxic organic pollutants and heavy metals, disrupting soil physicochemical properties, microbial communities, crop growth, and ultimately entering the human food chain.
Activities of Microplastics (MPs) in Agricultural Soil: A Review of MPs Pollution from the Perspective of Agricultural Ecosystems
This review summarizes the origins, migration, and fate of microplastics in agricultural soil ecosystems, identifying plastic mulch film, irrigation water, and organic fertilizers as major sources. The study highlights that microplastic accumulation in farmland can affect soil structure, microbial communities, and crop growth, with potential implications for food safety through the terrestrial food chain.

This review synthesizes research on microplastic contamination of soil environments, covering the major sources of soil microplastics, factors influencing their accumulation and distribution, and the environmental risks they pose to terrestrial ecosystems and agriculture.
Impact of Different Soil Tillage Practices on Microplastic Particle Abundance and Distribution
Field experiments across different tillage and fertilization regimes quantified microplastic abundance and vertical distribution in agricultural soils, finding that tillage practices significantly influenced how deeply microplastics are mixed through the soil profile.
Microplastics transport in soils: A critical review
Researchers reviewed how microplastics move through soil, finding that their transport depends on a complex mix of particle properties, soil chemistry, water flow, and biological activity — and that these factors often interact in ways that produce contradictory results across studies. The review maps these knowledge gaps and calls for more controlled experiments to predict where microplastics accumulate and how they might reach groundwater or crops.
Significance of Microplastics in Agricultural Soil
This review examines the significance of microplastic contamination in agricultural soils, estimating it contributes approximately 20% of total plastic pollution in terrestrial ecosystems. Microplastics enter farmland through irrigation, mulch, and sewage sludge, and can be transported deeper into soil by plant roots and soil organisms. The accumulation of microplastics in agricultural land poses risks to soil health and the food grown in it.
