ClearPolyethylene 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.
Nanoplastic alters soybean microbiome across rhizocompartments level and symbiosis via flavonoid-mediated pathways
Researchers applied polypropylene and polyethylene nanoplastics to soybean growing conditions and found that the particles altered soil chemistry, changed bacterial communities, and unexpectedly accelerated root nodule formation and nitrogen-fixing activity at lower doses. The effects varied by plastic type, with polyethylene nanoplastics having a stronger impact on soil enzyme activity. The study reveals that nanoplastic pollution can reshape the soil microbiome and influence how plants form beneficial partnerships with nitrogen-fixing bacteria.
Sub-micron microplastics affect nitrogen cycling by altering microbial abundance and activities in a soil-legume system
Researchers found that very small (sub-micron) polyethylene and polypropylene microplastics in soil significantly altered nitrogen cycling by changing the abundance and activity of bacteria around soybean roots. While the microplastics did not affect plant growth directly, they increased nitrogen uptake and shifted the balance of nitrogen-processing bacteria. These hidden changes to soil chemistry could have long-term effects on agricultural productivity and the nutritional quality of crops.
Polyethylene microplastic and soil nitrogen dynamics: Unraveling the links between functional genes, microbial communities, and transformation processes
Researchers conducted a six-month experiment to understand how polyethylene microplastics in soil affect nitrogen cycling, a process critical for soil fertility and plant nutrition. They found that while total nitrogen levels stayed stable, microplastics significantly altered the forms of nitrogen present by increasing ammonium and nitrate while decreasing dissolved organic nitrogen. The study suggests that microplastics reshape soil microbial communities and their nitrogen-processing activities, potentially disrupting the natural nutrient balance in agricultural soils.
Polyethylene 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.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
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.
Polyvinyl chloride and polybutylene adipate microplastics affect peanut and rhizobium symbiosis by interfering with multiple metabolic pathways
Researchers found that both PVC and biodegradable PBAT microplastics significantly disrupted the symbiotic relationship between peanut plants and nitrogen-fixing rhizobium bacteria. The microplastics reduced nodule formation by 33 to 100 percent and altered metabolic pathways involved in the symbiosis. The study suggests that microplastic contamination in agricultural soils could impair the natural nitrogen fixation process that legume crops depend on for healthy growth.

Researchers found that low-density polyethylene (LDPE) microplastic contamination in field soil negatively affected fenugreek plant growth, root nodulation, and rhizosphere microbial community structure, raising concerns about agricultural soil health.
Impact of Nanoplastic Contamination on Rhizosphere Microbiome and Plant Phenotype
This study examined how nanoplastic contamination affects the rhizosphere microbiome (soil bacteria around plant roots) and plant growth. Nanoplastic exposure altered soil microbial communities and reduced plant growth, suggesting these tiny plastic particles could disrupt the soil ecosystems that support food production.
Macroplastics in soybean cultivation: Neutral on plant growth but disruptive to nitrogen-fixing microbiome
Researchers studied how larger plastic debris (over 2 centimeters) in agricultural soil affects soybean growth and the nitrogen cycle over a 71-day experiment. While the macroplastics did not visibly affect plant growth, they significantly disrupted nitrogen-fixing bacterial communities and altered soil nitrogen chemistry. The study suggests that even when crop yields appear unaffected, plastic contamination in farmland may be quietly undermining the beneficial soil microorganisms that plants depend on.

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.

Researchers found that adding polyethylene microplastics to soil changed the bacterial communities and disrupted the nitrogen cycle, which is essential for soil fertility and plant growth.
