ClearPolyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality
Researchers studied how polyethylene microplastics at different concentrations affect soil microbial communities and overall ecosystem function in a maize growing system. They found that higher concentrations of microplastics shifted microbial community composition, reduced beneficial bacteria involved in nutrient cycling, and impaired multiple soil ecosystem functions simultaneously. The study suggests that microplastic contamination in agricultural soils can undermine the biological processes that support healthy crop growth.

Agri-plastics in soils drive changes in the rhizosphere bacterial community and plant transcriptome in Arabidopsis
Researchers grew Arabidopsis thaliana in soils mixed with plastic film residues (≥5 mm at 5% w/w) and examined rhizosphere bacterial communities and plant gene expression. Plastic residues significantly altered rhizobacterial composition without affecting plant growth or flowering, suggesting soil microbiome disruption may precede visible plant effects.
Potential impacts of polyethylene microplastics and heavy metals on Bidens pilosa L. growth: Shifts in root-associated endophyte microbial communities
Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.
Influence of soil microplastic contamination on maize (Zea mays) development and microbial dynamics
Researchers grew maize (corn) in soil contaminated with varying amounts of microplastics and found that higher microplastic levels disrupted soil bacteria and fungi, caused leaf damage like yellowing and tissue death, and led to elevated heavy metals in plant tissue above safe limits. The results point to serious risks microplastics pose to crop health, soil ecosystems, and food safety.
Polyethylene and polyvinyl chloride microplastics promote soil nitrification and alter the composition of key nitrogen functional bacterial groups
Researchers found that polyethylene and PVC microplastics in soil increased nitrification (a key step in the nitrogen cycle) and changed the composition of nitrogen-processing bacteria. These changes could affect soil fertility and the availability of nutrients for crops. The study highlights how microplastic contamination in agricultural soil may have hidden effects on food production by altering fundamental soil processes.
Microplastics increase soil microbial network complexity and trigger diversity-driven community assembly
Researchers found that microplastics in soil increased bacterial network complexity and shifted microbial community assembly in a diversity-dependent manner, with high-density polyethylene causing more harm to plant growth than polystyrene or polylactic acid particles.
Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.

The results suggest that soil management history influences how resilient soil microbiomes are to microplastic contamination.
Soil plastisphere interferes with soil bacterial community and their functions in the rhizosphere of pepper (Capsicum annuum L.)
Scientists found that microplastics in soil create their own unique microbial communities, called the plastisphere, which can include potential human pathogens and plastic-degrading bacteria. These plastisphere communities interacted with the bacteria around pepper plant roots, potentially affecting plant health and soil function. The study suggests that microplastic contamination in farm soil could change the microbial environment around food crops and possibly introduce harmful bacteria into the food production system.
