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.
Polyethylene Microplastics Inhibit Peanut Nodulation via Metabolic and Transcriptional Pathways
Scientists found that tiny plastic pieces from agricultural plastic films prevent peanut plants from forming healthy partnerships with beneficial soil bacteria that help them grow. These microplastics disrupt the plant's natural processes and block the formation of root nodules, which are essential for peanuts to get nitrogen from soil bacteria. This matters because it shows how plastic pollution in farmland could reduce crop yields and food production, potentially affecting our food supply.

Researchers examined how polyethylene microplastic contamination in soil affects the bacterial communities associated with legume plant root nodules. They found that microplastic treatments accelerated nodule formation but disrupted the balance of beneficial nitrogen-fixing bacteria in the nodules. The study suggests that soil microplastic pollution may interfere with the symbiotic relationship between legume crops and their nitrogen-fixing bacterial partners.
Responses of maize (Zea mays L.) seedlings growth and physiological traits triggered by polyvinyl chloride microplastics is dominated by soil available nitrogen
Researchers found that PVC microplastics in soil reduced maize seedling growth primarily by depleting available nitrogen, a nutrient essential for plant development. The microplastics altered soil bacteria, enzymes, and nutrient levels, with nitrogen availability explaining nearly 88% of the changes in plant growth. This suggests that microplastic pollution in agricultural soil could reduce crop yields by starving plants of essential nutrients.
Response of peanut plant and soil N-fixing bacterial communities to conventional and biodegradable microplastics
Researchers tested how conventional plastics (polyethylene and polystyrene) and a biodegradable plastic (polylactic acid) affect peanut plant growth and nitrogen-fixing soil bacteria. They found that while none of the plastics reduced plant biomass, the biodegradable PLA at high doses dramatically altered soil nitrogen levels and bacterial community composition. The study suggests that biodegradable plastics may not be as harmless to agricultural soil ecosystems as commonly assumed.
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 affect the nitrogen nutrition status of soybean by altering the nitrogen cycle in the rhizosphere soil
Researchers investigated how three types of microplastics — polystyrene, polyethylene, and polyvinyl chloride — affect soybean growth by altering nitrogen cycling in the root-zone soil. They found that polyethylene and polystyrene promoted nitrogen availability and soybean growth, while polyvinyl chloride disrupted the nitrogen cycle, reduced beneficial soil microorganisms, and inhibited plant growth. The study suggests that different types of microplastics can have opposing effects on crop nutrition through their impact on soil microbial communities.
Response of common bean (Phaseolus vulgaris L.) growth to soil contaminated with microplastics
A pot experiment adding LDPE and biodegradable (PLA/PBAT) microplastics to soil at 0.5–2.5% by weight found no significant effects on common bean shoot or root biomass, though higher LDPE concentrations increased specific root nodules, suggesting subtle effects on nitrogen-fixing symbiosis.
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.
Biodegradable and conventional mulches inhibit nitrogen fixation by peanut root nodules – potentially related to microplastics in the soil
A four-year mulching experiment with peanuts found that both conventional polyethylene and biodegradable (PLA-PBAT) plastic mulches reduced root nodule nitrogen fixation by 54–59%, with microplastics from the mulch films likely contributing to this suppression. Since biological nitrogen fixation is a key natural process that reduces the need for synthetic fertilizers, this finding suggests that agricultural plastic use may have hidden costs for soil fertility and farming sustainability.
Effects of polyethylene microplastics and cadmium co-contamination on the soybean-soil system: Integrated metabolic and rhizosphere microbial mechanisms
Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.
The impact of arbuscular mycorrhizal fungi and endophytic bacteria on peanuts under the combined pollution of cadmium and microplastics
Researchers tested whether beneficial soil fungi and bacteria could help peanut plants cope with combined contamination from cadmium and microplastics. They found that the microbial treatment effectively trapped cadmium in the plant roots, preventing it from moving into the shoots and edible parts. The study suggests that harnessing natural soil microbes could be a practical strategy for growing safer food in polluted farmland.
