Microplastics abundance associated with farmland use types and the impact on soil microbial communities: A case study in Southern China
Researchers surveyed microplastic contamination across orchard, paddy field, and vegetable field soils in Southern China and analyzed how it affected soil microbial communities. They found microplastic levels ranging widely across sites, with very small particles under 30 micrometers being most common, and identified 32 different polymer types. 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.

Effect of microplastics used in agronomic practices on agricultural soil properties and plant functions: Potential contribution to the circular economy of rural areas
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.
