ClearSelenium alleviates the adverse effects of microplastics on kale by regulating photosynthesis, redox homeostasis, secondary metabolism and hormones
Researchers found that treating soil with selenium could protect kale plants from the harmful effects of microplastic contamination. Microplastics triggered damaging oxidative stress in the plants, but selenium helped restore the balance by boosting antioxidant defenses, improving photosynthesis, and regulating plant hormones. This suggests selenium supplementation could help maintain food crop health in microplastic-contaminated agricultural soils.
Concentration-Dependent Impacts of Microplastics on Soil Nematode Community in Bulk Soils of Maize: Evidence From a Pot Experiment
Researchers found that polypropylene microplastics altered soil nematode community composition in a concentration-dependent manner, reducing bacterivore abundance and shifting the soil food web structure, indicating disrupted soil ecological functioning in agricultural settings.
Microplastics in soil can increase nutrient uptake by wheat
Researchers found that microplastics in soil can increase nutrient uptake by wheat by stimulating microbial activity and altering root interactions, suggesting microplastics may disrupt natural nutrient-cycling strategies in agricultural systems.
Revealing the Selenium-Mediated Regulatory Mechanisms of P. stratiotes in Response to Nanoplastics Stress from Multiple Perspectives of Transcriptomics, Metabolomics, and Plant Physiology
Scientists found that tiny plastic particles (nanoplastics) seriously damage water plants by disrupting their ability to make food from sunlight and causing harmful stress inside their cells. However, when researchers added selenium (a natural mineral) to the water, it helped protect the plants from plastic damage by boosting their natural defense systems. This research could help us clean up plastic pollution in lakes and rivers, which is important since these water sources can affect human health through drinking water and food chains.
Mitigating the detrimental impacts of low- and high-density polyethylene microplastics using a novel microbial consortium on a soil-plant system: Insights and interactions
Researchers tested a novel microbial consortium containing bacterial and fungal strains to mitigate the harmful effects of polyethylene microplastics on soil and sunflower growth. The study found that microplastics altered soil pH, electrical conductivity, and organic carbon levels, but the microbial consortium treatment helped counteract some of these detrimental effects on the soil-plant system.
Silicon regulates microplastic-induced phytotoxicity and its detoxification mechanism: A plant-microbe perspective
Researchers investigated whether silicon supplements could protect kale from the harmful effects of polyethylene microplastics in soil. They found that silicon increased plant biomass by 16-25% and reversed microplastic-induced suppression of soil enzymes, while also promoting beneficial soil bacteria. The study suggests that silicon could be a practical strategy for improving crop resilience in microplastic-contaminated agricultural soils.
Uncovering the intricate relationship between plant nutrients and microplastics in agroecosystems
A study of wheat grown in soils with varying microplastic levels found complex interactions between MPs and plant macronutrients and micronutrients, with MPs altering nutrient uptake in ways that could affect crop productivity in contaminated agricultural soils.
Microplastic particles alter wheat rhizosphere soil microbial community composition and function
Researchers found that microplastic particles altered wheat rhizosphere soil microbial community composition and function, with different polymer types inducing distinct shifts in bacterial diversity and nutrient cycling processes.
Effects of inorganic and organic selenium intervention on resistance of radish to arsenic stress
Researchers studied how organic and inorganic selenium supplements affect arsenic uptake in radish plants under arsenic stress conditions. They found that organic selenium was more effective than inorganic selenium at reducing arsenic absorption and improving the plants' antioxidant defenses. While not directly about microplastics, the study contributes to understanding how soil amendments can help crops resist environmental contaminant stress.
Dual-Stress Mitigation of Sclerotinia under Microplastic Toxicity by Nano-Selenium: Redox Balance, Pathogen Suppression, and Transcriptome Reprogramming
Researchers investigated whether selenium nanoparticles could protect rapeseed plants from combined stress caused by microplastics and the fungal pathogen Sclerotinia. The study found that selenium nanoparticles improved photosynthesis, reduced oxidative damage, and showed strong antifungal activity, suggesting they may help mitigate microplastic-induced phytotoxicity and fungal disease in agricultural settings.

Microplastics Reduce the Negative Effects of Litter-Derived Plant Secondary Metabolites on Nematodes in Soil
Researchers found that microplastics in soil reduced the toxic effects of plant-derived chemicals (phenolic compounds from leaf litter) on soil nematodes. The microplastics appeared to absorb the plant chemicals, reducing their bioavailability to the worms. This shows that microplastics can change soil chemistry in unexpected ways, potentially altering how soil ecosystems function.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
Effects of polystyrene microplastics on the agronomic traits and rhizosphere soil microbial community of highland barley
Researchers investigated how polystyrene microplastics of different sizes and concentrations affect highland barley growth and the microbial communities in surrounding soil. They found that smaller particles reduced grain weight while larger particles decreased spike dimensions, and all microplastic treatments significantly lowered soil bacterial diversity. The study also showed that adding degrading bacteria helped restore microbial community structure closer to normal conditions.

This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
