ClearDistribution characteristics of soil microplastics and their impact on soil physicochemical properties in agricultural areas of the North China plain
Microplastics are accumulating across agricultural soils of the North China Plain, with this study finding moderate-to-low abundance across multiple land use types and detecting that plastic particles affect soil texture, bulk density, and water-holding capacity. Altered soil physical properties from microplastic contamination could impair crop growth and soil fertility over time, with implications for food security.
Effects of land use/land cover change on soil physicochemical properties and soil carbon stock in Kochore district, southern Ethiopia
This study examined how changes in land use in southern Ethiopia affected soil quality and carbon storage over 20 years. While not about microplastics directly, the research is relevant because degraded soils from intensive farming are more vulnerable to microplastic contamination, and healthy agroforestry soils store more carbon and maintain better structure. Understanding soil health is important context for assessing how microplastics affect agricultural land.

Evaluating the impacts of microplastics on agricultural soil physical, chemical properties, and toxic metal availability: An emerging concern for sustainable agriculture
This study tested how five common types of microplastics affect soil properties and heavy metal availability in agricultural soil over 90 days. Microplastics changed soil structure, nutrient levels, and water-holding capacity, and actually reduced the availability of toxic heavy metals at higher plastic concentrations -- highlighting the complex ways plastic pollution is altering the farmland that produces our food.
The microplastics distribution characteristics and their impact on soil physicochemical properties and bacterial communities in food legumes farmland in northern China
Researchers surveyed farmland soil across five provinces in northern China and found microplastic contamination ranging from 1,600 to over 36,000 particles per kilogram of soil. Most of the microplastics were small fibers and fragments, primarily from agricultural plastic film and organic fertilizer use. The study found that microplastic presence altered soil properties and shifted bacterial community composition, suggesting these particles may affect soil health in food-growing regions.

Researchers found that microplastic accumulation in agricultural soils of Xinjiang, China increases significantly with mulching history, with fields mulched for over 20 years containing substantially more microplastics across all soil layers.
Silent Alienation of Soils through Microplastic in the Anthropocene – A Constraint for Soil Productivity?
This review examines how microplastics accumulate in soils and alter their physical properties and biological communities over time. Microplastics resist biodegradation and can reduce soil porosity, alter water retention, and harm soil organisms. The authors argue that ongoing plastic accumulation in farmland poses a long-term threat to soil productivity and global food security.

Macro- and micro-plastics change soil physical properties: a systematic review
This systematic review examines how plastic particles — both large and microscopic — change important soil properties like water retention, density, and structure. These changes can affect how well soil supports plant growth and produces food, raising concerns about the long-term impact of plastic pollution on agriculture.
Abundance and characteristics of microplastics in soils with different agricultural practices: Importance of sources with internal origin and environmental fate
Microplastic abundance and characteristics were examined in soils representing four agricultural practice types in Chinese farmland to evaluate the influence of land use on plastic particle accumulation. Microplastic concentrations and polymer types varied by agricultural practice, with plastic mulch film use and irrigation water source as key drivers of farmland soil contamination.

Researchers investigated microplastic distribution in paddy soils following long-term plastic film mulching in Southwest China, finding that ten years of continuous mulching significantly increased filmy microplastic accumulation and that weathering altered the chemical properties of these particles.
Determinants of environmental changes in human-modified ecosystems: Effects of plastics on moisture gradients, nutrients, and clay properties
Researchers examined how plastic pollution affects soil properties in human-modified ecosystems through field experiments in China and Rwanda, combined with laboratory tests on clay mixed with PET microplastics.

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.
