ClearMicroplastics 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.

Investigation of the effects of polyethylene microplastics at environmentally relevant concentrations on the plant-soil-microbiota system: A two-year field trial
Researchers conducted a two-year field trial to study how polyethylene microplastics at environmentally relevant concentrations affect crops, soil, and microbial communities in a rice-wheat rotation system. They found that microplastics did not harm wheat growth but actually increased rice grain weight and plant height, while reducing soil nutrient levels including nitrogen and phosphorus. The study reveals that microplastics can alter soil bacterial communities and disrupt metabolic processes in ways that differ between crop seasons.
The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
Researchers investigated how different types of microplastics interact with soil nutrient availability and weed competition to affect crop growth. The study found that the effects of microplastics on plant performance depend on the polymer type and are modulated by fertilization levels and competition from weeds, suggesting that real-world agricultural impacts of microplastic pollution may be more complex than laboratory studies indicate.
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.
Microplastics in terrestrial ecosystem: Exploring the menace to the soil-plant-microbe interactions
This review summarizes existing research on how microplastics affect the complex relationships between soil, plants, and soil microbes. Microplastics alter soil structure, change the makeup of microbial communities, and disrupt beneficial partnerships between plants and helpful fungi and bacteria. These disruptions can reduce plant growth and nutrient cycling, which could ultimately affect crop yields and the quality of food produced on microplastic-contaminated farmland.
Microplastics reduce the wheat (Triticum aestivum L.) net photosynthetic rate through rhizospheric effects
Microplastics were shown to reduce the net photosynthesis and growth of wheat plants, with effects increasing at higher plastic concentrations. This demonstrates that microplastic contamination in agricultural soils poses a direct threat to crop productivity and food security.
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.
The Impact of Microplastic Pollution in Soils on The Uptake of Plant Nutrient Elements
A review study found that soil microplastic contamination interferes with plants' ability to absorb essential nutrients including nitrogen, phosphorus, and potassium, with effects varying by plastic type, concentration, and particle size. This has direct implications for food security, as crops grown in microplastic-contaminated soils may suffer nutrient deficiencies even when adequate fertilizer is applied.
Cascading effects from soil to maize functional traits explain maize response to microplastics disturbance in multi-nutrient soil environment
Researchers found that microplastics in agricultural soil can dry out the soil and disrupt nutrient availability for maize plants, but the crop partially compensates by growing longer, more efficient roots to forage for nutrients. This adaptive response — more pronounced in nutrient-rich soils — means microplastic impacts on crop yields depend heavily on soil conditions, complicating efforts to predict food security risks from plastic pollution.
Micro and nano-plastics on environmental health: a review on future thrust in agro-ecotoxicology management
This review examines the growing body of evidence on how microplastics and nanoplastics affect plant health, soil microbial communities, and agricultural productivity. The study highlights that plastic accumulation in agricultural soils can alter crop growth and yield while disrupting soil ecosystem dynamics, and calls for greater attention to agro-ecotoxicology management to address these emerging threats to food production.
Diversity and interactions of rhizobacteria determine multinutrient traits in tomato host plants under nitrogen and water disturbances
Researchers investigated how root-associated bacteria help tomato plants maintain nutrient uptake under nitrogen and water stress conditions. They found that microbial diversity and species interactions were key factors in supporting the plant's ability to acquire multiple nutrients simultaneously. While not directly about microplastics, the study advances understanding of soil microbiome dynamics that are relevant to agricultural systems increasingly affected by plastic contamination.
Particulate plastics-plant interaction in soil and its implications: A review
This review examines how micro- and nanoplastics in soil interact with plants, including uptake through roots, accumulation in plant tissues, and effects on growth, nutrient absorption, and soil microbial communities. The study highlights that these plastic particles can alter soil structure and chemistry in ways that affect crop development, raising concerns about food safety and agricultural productivity.
The Effect of Microplastics-Plants on the Bioavailability of Copper and Zinc in the Soil of a Sewage Irrigation Area
Researchers examined how different concentrations of microplastics affect the bioavailability of copper and zinc in sewage-irrigated soils, finding that microplastics can alter heavy metal mobility and plant uptake, with implications for food safety in contaminated agricultural areas.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
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.
Microplastic-induced changes in Cd and Cr behavior in the agricultural soil-wheat system: Insights into metal bioavailability and phytotoxicity
When common microplastics were added to agricultural soil growing wheat, they lowered soil pH and made toxic heavy metals like cadmium and chromium more available for plant uptake. The wheat plants showed signs of stress and accumulated more of these metals in their tissues, which is concerning because contaminated crops could pass these toxins along to people who eat them.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
