ClearImpact of Different Soil Tillage Practices on Microplastic Particle Abundance and Distribution
Researchers compared microplastic particle abundance and depth distribution in agricultural soils under conventional tillage, minimum tillage, and no-till practices, finding that tillage intensity affected both total MP concentrations and the vertical mixing of particles through the soil profile.
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 study examined how microplastic particles are incorporated into soil in agricultural settings, finding that farming practices — particularly tillage and irrigation — facilitate microplastic mixing through the soil profile.
Microplastic distribution and transport in agricultural soils : from field to burrow scale
Researchers investigated the spatial distribution and transport of microplastics in agricultural soils through field surveys and laboratory experiments. They found that sewage sludge amendments led to significantly higher microplastic contamination than mineral fertilizers, and that earthworm activity was a key mechanism for moving plastic particles deeper into soil. The study highlights the importance of accounting for both horizontal and vertical microplastic transport in soils when assessing agricultural 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.
Processes 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.
Spatial distribution of microplastics in Mollisols of the farmland in Northeast China: the role of field management and plastic sources
Researchers investigated how farmland management practices affect the distribution of microplastics in vegetable fields in Northeast China. They found seven types of plastic polymers in soil layers down to 30 centimeters, with larger macroplastic fragments being the primary source of microplastic contamination. Higher fertilization doses contributed more to microplastic generation than tillage frequency.
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.
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.
Vertical distribution of microplastics in urban farmland soils. A case of Mabibo Bonde la Mchicha farm, Dar es Salaam, Tanzania
Researchers mapped the vertical distribution of microplastics in farmland soils in an urban fringe area, finding that particles were not uniformly distributed by depth and that agricultural tillage influenced vertical mixing. Fibers and fragments were most abundant, predominantly from agricultural plastic films and irrigation water.
Indirect Effects of Microplastic-Contaminated Soils on Adjacent Soil Layers: Vertical Changes in Soil Physical Structure and Water Flow
Laboratory experiments showed that microplastic contamination in upper soil layers indirectly altered the physical structure and water flow of adjacent uncontaminated lower soil layers, suggesting that microplastics can affect soil hydrology beyond their immediate zone of contamination.
Microplastic accumulation in agricultural soils: Source apportionment and impact on soil microbial community structure
Researchers investigated microplastic accumulation patterns in intensively farmed agricultural soils at multiple depth intervals, using polymer fingerprinting to apportion contamination sources among plastic mulch, treated wastewater irrigation, and organic amendment application. The study assessed impacts on soil microbial community structure using FTIR-confirmed microplastics extracted by zinc chloride density flotation.
Vertical transport of microplastic in agricultural soil in controlled irrigation plot experiments
Researchers conducted field plot experiments in agricultural soil and found that microplastics migrate vertically with irrigation water, with smaller particles (53–63 µm) penetrating up to 6 cm deep and larger particles remaining near the surface, indicating that water infiltration is a key driver of subsurface plastic transport.

Researchers measured the effects of microplastics used in common agricultural practices — including mulch film residues and irrigation-delivered particles — on soil physical, chemical, and biological properties. Microplastic presence altered soil aggregation, water retention, and microbial community composition, with effects depending on plastic concentration, polymer type, and soil texture.
Investigating microplastic dynamics in soils: Orientation for sampling strategies and sample pre‐procession
This study develops improved methods for sampling and detecting microplastics in soil, addressing a major gap in current research.

Better detection protocols will help scientists accurately measure how much microplastic is accumulating in agricultural and natural soils.
