ClearMicroplastics reduce nitrogen uptake in peanut plants by damaging root cells and impairing soil nitrogen cycling
Researchers found that microplastics reduce nitrogen uptake in peanut plants by damaging root cells and impairing soil nitrogen cycling, with polypropylene and rubber crumb particles at high concentrations inhibiting plant growth and disrupting the soil-plant nitrogen system.
Inhibition of Peanut (Arachis hypogaea L.) Growth, Development, and Promotion of Root Nodulation Including Plant Nitrogen Uptake Triggered by Polyvinyl Chloride Microplastics
Researchers investigated the impact of polyvinyl chloride (PVC) microplastics at four dosages (0.5%, 1.5%, 2.5%, and 3.5%) on the growth, development, root nodulation, and nitrogen uptake of peanut (Arachis hypogaea L.) plants. They found that PVC microplastics inhibited plant growth and development while paradoxically promoting root nodulation, suggesting complex soil-plant-microbiome interactions that could have implications for nitrogen cycling and food security in contaminated agricultural soils.
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.

Aged polyethylene microplastics modulate herbicide and antibiotic bioavailability and plant responses: A case study with glyphosate and tetracycline
Scientists found that tiny plastic particles commonly found in farm soil can stick to plant roots and change how plants absorb harmful chemicals like pesticides and antibiotics. The plastic pieces made plants more stressed and damaged, reducing important nutrients like chlorophyll by 30%. This matters because it could affect the safety and quality of the food we eat, since these plastic particles are becoming more common in agricultural areas where our crops are grown.
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.
Microplastics from agricultural mulch films: a threat to growth promoting abilities of bacteria?
Researchers tested how microplastics shed from agricultural plastic mulch films affect soil bacteria that promote plant growth, finding that mulch-derived microplastics reduced the abundance and activity of key plant growth-promoting bacteria. The results suggest agricultural plastic use could undermine soil health and crop productivity.
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.
Deciphering the response of nodule bacteriome homeostasis in the bulk soil-rhizosphere-root-nodule ecosystem to soil microplastic pollution
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.
Effects of microplastic type on growth and physiology of soil crops: Implications for farmland yield and food quality
Researchers tested how two common types of microplastics (polypropylene and polyester) affect corn, soybean, and peanut crops grown in real farm conditions. The effects varied by crop and plastic type, with polypropylene generally reducing peanut growth while polyester had milder impacts. These findings suggest that microplastic contamination in agricultural soil could affect crop yields and food quality in ways that depend on which plastics are present.
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.
Mechanisms of microplastic accumulation in the root zones of agricultural soils
Scientists found that tiny plastic pieces from farm materials like mulch films get stuck in soil and don't wash away easily, causing them to build up over time in areas where food is grown. This matters because these microplastics can potentially enter our food supply through crops that absorb them from contaminated soil. The research shows it's very difficult to remove these plastic particles once they're in farmland, suggesting we need better prevention methods to protect our food system.
Unveiling the Effects of Polypropylene Microplastics (PP-MPs) on Growth Attributes and Antioxidant Defense System in Wheat (Triticum aestivum L.)
Scientists found that tiny plastic particles from everyday items like food containers can harm wheat plants when present in soil at higher levels, stunting their growth and reducing important nutrients. This matters because wheat is a major food crop worldwide, and if microplastics continue building up in farmland soil, it could affect our food supply and the nutritional quality of foods we eat. The study shows that plastic pollution isn't just an ocean problem—it's also threatening the crops that feed us.
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.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil

Unraveling the impact of nano-microscale polyethylene and polypropylene plastics on Nicotiana tabacum: Physiological responses and molecular mechanisms
Researchers exposed tobacco plants to polyethylene and polypropylene microplastics of different sizes and found that both types suppressed plant growth in a dose-dependent manner, with polypropylene being more toxic. The microplastics disrupted photosynthesis, triggered oxidative stress, and altered hormone signaling and defense pathways in the plants. These findings demonstrate that microplastic contamination in soil can impair crop growth at the molecular level, potentially affecting agricultural productivity.
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.
Microplastic exposure inhibits nitrate uptake and assimilation in wheat plants
This study found that polystyrene microplastics in soil significantly reduced wheat plants' ability to absorb nitrate, an essential nutrient for growth. The microplastics damaged roots and shut down key genes needed for nutrient uptake and processing. This matters because microplastic contamination in farmland could reduce crop yields and lower the nutritional quality of the food we grow.
Effects of microplastics on selected physical properties of agricultural soils and on the response of the selected terrestrial isopod
Scientists found that tiny plastic pieces from agricultural films change how soil holds and releases water, with some types increasing available water for plants by about 5%. These microplastics also affect soil creatures that help keep ecosystems healthy. This matters because these plastic particles could be changing how our food is grown and may eventually end up in the crops we eat.

Researchers found that tire-derived microplastics in soil harmed peanut plant growth and disrupted soil bacteria, but adding biochar with a specially designed bacterial community helped counteract the damage. The biochar treatment restored soil health, improved microbial diversity, and boosted peanut growth even in microplastic-contaminated soil. This approach could help protect food crops from the harmful effects of microplastic pollution in agricultural land.
Biodegradable microplastics-induced free-living nitrogen fixation enhancement and diazotrophic community differentiation in soils
Scientists found that tiny pieces of biodegradable plastic in farm soil actually boost the activity of helpful bacteria that add nitrogen to the soil, which plants need to grow. However, these same plastic pieces also reduce other important nutrients in the soil and change which types of bacteria live there. This matters because as farmers use more biodegradable plastics, we need to understand how the tiny plastic pieces left behind might affect our food production and soil health.
Influence of polyethylene microplastics on Brassica rapa: Toxicity mechanism investigation
Researchers exposed the fast-growing plant Brassica rapa (related to turnip and cabbage) to polyethylene microplastics that had been degraded by sunlight, finding that the plastics stunted plant growth by up to 51% and triggered cellular stress responses. Genetic analysis revealed the microplastics disrupted the plant's immune and growth pathways, providing insight into how plastic pollution in agricultural soil could affect food crops.

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.
