Microplastics contamination in soil affects growth and root nodulation of fenugreek (Trigonella foenum‐graecum L.) and 16 s rRNA sequencing of rhizosphere soil
Summary
Researchers found that low-density polyethylene (LDPE) microplastic contamination in field soil negatively affected fenugreek plant growth, root nodulation, and rhizosphere microbial community structure, raising concerns about agricultural soil health.
The study aimed to observe the effect of low LDPE (low-density polyethylene) microplastics (MPs) contamination of soil on the growth of the Fenugreek plant, the number of root nodulation formation, leghaemoglobin (Lb) content of nodules, and metagenomics of rhizosphere soil. This study was performed in the field area, and Fenugreek seeds were sown, MPs contaminated soils, and their effect on plant growth was observed. Analysis of microbial community in rhizosphere soil was observed by 16S rRNA gene sequencing. A significant increase in the height of plants in the microplastic treated soil was observed. No detrimental effects of MPs were detected on the other physiological growth parameters of the plants, including the number of leaves, stem diameter, chlorophyll content, number of root nodules, or the leghaemoglobin content. The microbial composition in the rhizosphere soil was significantly altered in the presence of MPs. The abundance of order Rhizobiales (genus Rhizobium) was highly reduced in microplastic-treated soil. In contrast, various plastic degrading and pathogenic bacteria were selectively accumulated in soil due to the presence of MPs.

Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
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.
Impact of Nanoplastic Contamination on Rhizosphere Microbiome and Plant Phenotype
This study examined how nanoplastic contamination affects the rhizosphere microbiome (soil bacteria around plant roots) and plant growth. Nanoplastic exposure altered soil microbial communities and reduced plant growth, suggesting these tiny plastic particles could disrupt the soil ecosystems that support food production.
[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.
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.
