ClearSilicon alleviates the toxicity of microplastics on kale by regulating hormones, phytochemicals, ascorbate-glutathione cycling, and photosynthesis
Researchers found that microplastic pollution inhibits the growth of kale by disrupting its photosynthesis, hormone regulation, and antioxidant defenses. However, adding silicon to the soil helped protect the plants by strengthening their natural stress-response systems, suggesting silicon could be a practical strategy for growing safer food in microplastic-contaminated soils.
Selenium 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.

Researchers found that growing plants in soil contaminated with microplastics helped protect the soil ecosystem compared to unplanted soil. The root systems of plants stabilized the soil's microbial communities and reduced the carbon emissions caused by microplastic pollution, suggesting that maintaining plant cover could be one strategy to limit the environmental damage from microplastics in farmland.
Silicon mitigates combined cadmium and microplastics toxicity in rice by regulating glyoxalase system, and phytochelatin-mediated cadmium detoxification
Researchers demonstrated that foliar silicon application mitigates the combined toxicity of cadmium and microplastics in rice by enhancing antioxidant defenses, stimulating phytochelatin production to sequester cadmium, suppressing cadmium-uptake gene expression, and restoring chlorophyll content and hormone signaling to recover crop yield.
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.
From the rhizosphere to plant fitness: Implications of microplastics soil pollution
Researchers exposed strawberry plants to low-density polyethylene microplastics in soil and found significant harm, including reduced chlorophyll levels, altered nutrient uptake, and increased stress responses. The microplastics also shifted the soil microbiome toward potentially harmful fungi and bacteria. These findings show that microplastics in agricultural soil can damage crop health and change the microbial community that plants depend on.
Microplastics Modulate Carbon Sequestration in PaddyFields by Regulating Rhizosphere Silicon Mobility
Researchers investigated how biodegradable PLA and non-degradable PE microplastics alter rhizosphere silicon dynamics, carbon metabolism, and soil carbon storage in a rice paddy growth-cycle microcosm experiment. PLA transiently boosted grain carbon accumulation by 33% via altered silicon translocation, while PE reduced accumulation by 26-40%; both types ultimately disrupted long-term silicon bioavailability and carbon-silicon biogeochemical cycling in paddy fields.
The role of microplastic pollution in the modification of the physicochemical properties of arable soil and uptake of potential toxic elements by plants
Researchers conducted a series of studies analyzing how microplastic pollution modifies the physicochemical properties of arable soil and affects the uptake of potentially toxic heavy metals by plants, beginning with a comprehensive literature review of microplastic interactions with plant physiology, metals, pesticides, and pathogens.
Plant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.
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.
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.
Biochar alleviated the toxic effects of PVC microplastic in a soil-plant system by upregulating soil enzyme activities and microbial abundance
Researchers tested whether adding biochar to soil could reduce the harmful effects of PVC microplastic contamination on plant growth and soil health. They found that biochar amendment increased plant biomass, restored soil enzyme activity, and boosted beneficial microbial populations that had been suppressed by the microplastics. The study suggests that biochar could serve as a practical tool for rehabilitating agricultural soils contaminated with plastic particles.
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.
Tiny pollutants, big consequences: investigating the influence of nano- and microplastics on soil properties and plant health with mitigation strategies
Researchers reviewed the impact of nanoplastics and microplastics on soil properties and plant health, examining absorption and translocation mechanisms in plants. The study suggests that plastic particles alter soil structure and microbial communities, impair plant growth and nutrient uptake, and proposes mitigation strategies to address these emerging threats to agricultural ecosystems.
Exploring the potential of biochar for the remediation of microbial communities and element cycling in microplastic-contaminated soil
Scientists found that adding biochar (a charcoal-like material made from plant waste) to soil contaminated with microplastics helped restore healthy microbial communities and nutrient cycling. The biochar reversed negative effects that microplastics had on soil chemistry, including nitrogen and phosphorus availability. This suggests biochar could be a practical tool for repairing farmland damaged by microplastic pollution.

Microplastics alter soil enzyme activities and microbial community structure without negatively affecting plant growth in an agroecosystem
Researchers tested how three types of microplastics (polystyrene, polyethylene, and PVC) affected plant growth, soil enzymes, and microbial communities in an agricultural setting. The study found that while microplastics suppressed several soil enzyme activities and altered carbon cycling, they did not negatively affect plant growth and in some cases actually enhanced above-ground and below-ground plant productivity.

The study suggests that soil microplastic pollution may interfere with the symbiotic relationship between legume crops and their nitrogen-fixing bacterial partners.
