The study shows that farmland use type and agricultural practices like plastic mulching significantly influence both the amount and type of microplastic contamination in soils.
Effects of land use and landscape on the occurrence and distribution of microplastics in soil, China
Researchers investigated how land use patterns affect microplastic contamination in soils across different agricultural, orchard, grassland, and woodland areas in Yunnan Province, China. Agricultural lands, especially those with greenhouses and traditional farming, had significantly higher microplastic levels than grasslands and woodlands, with fragments being the dominant shape. The study suggests that farming practices, including plastic mulch use and fertilizer application, are major contributors 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.
Abundance, spatial distribution, and characteristics of microplastics in agricultural soils and their relationship with contributing factors

Impact of plastic film mulching on microplastic in farmland soils in Guangdong province, China
Researchers surveyed farmland in Guangdong, China's largest economic province, to determine how much plastic mulch film contributes to soil microplastic pollution. They found that fields using plastic mulch had significantly higher microplastic levels than those without, and the contamination correlated with years of mulch use. The study helps clarify the direct agricultural contribution to soil microplastic pollution in regions with many overlapping pollution sources.

Meta-analysis of 321 observations across Chinese agricultural soils found that vegetable-growing soils had the highest microplastic contamination, followed by orchards, cropland, and grassland. Agricultural film mulch significantly increased soil microplastic levels, especially in orchards, while higher population density and economic activity correlated with increased contamination across all land types.
