ClearEffects of cadmium contamination on bacterial and fungal communities in Panax ginseng-growing soil
Researchers examined how cadmium (a toxic heavy metal) contamination in soil affects the microbial communities around ginseng crops, finding that even low cadmium levels significantly disrupted bacterial diversity more than fungal diversity. Certain bacterial groups that tolerate cadmium became dominant, while beneficial microbes declined — changes that could affect soil health and ginseng safety.
The effect of intercropping leguminous green manure on theanine accumulation in the tea plant: A metagenomic analysis
Researchers examined how intercropping tea plants with leguminous green manure affects the accumulation of theanine, a key amino acid in tea. Using soil DNA analysis, they found that the green manure promoted nitrogen-cycling bacteria that enhanced nutrient availability for the tea plants. While the study focuses on agricultural practices, it provides insight into how soil microbial communities respond to different cropping strategies.
Metagenomics reveals the response of desert steppe microbial communities and carbon-nitrogen cycling functional genes to nitrogen deposition
Researchers used metagenomics to study how nitrogen deposition affects soil microbial communities and carbon-nitrogen cycling in desert steppe ecosystems. The study provides insights into how anthropogenic nitrogen inputs alter microbial functional gene expression, which can influence broader soil ecosystem processes.
Long-Term Compost Amendment Changes Interactions and Specialization in the Soil Bacterial Community, Increasing the Presence of Beneficial N-Cycling Genes in the Soil
Researchers found that long-term compost amendment significantly altered soil bacterial community structure and functional specialization, increasing microbial network complexity and promoting functional guilds associated with organic matter decomposition compared to non-amended soils.
Moderate Nitrogen Reduction Increases Nitrogen Use Efficiency and Positively Affects Microbial Communities in Agricultural Soils
A field study found that moderate nitrogen reduction did not significantly reduce crop yield due to increased nitrogen use efficiency driven by higher available phosphorus and potassium, while short-term nitrogen changes had limited effects on soil microbial community structure but increased nitrification-related bacterial functions.
Soil microbial community composition and nitrogen enrichment responses to the operation of electric power substation
Researchers collected soil samples from seven sites at varying distances from an electric power substation in southeastern China and used metagenomic sequencing to characterize microbial diversity and nitrogen cycling processes. They found that proximity to the substation reduced nitrogen fixation capacity and increased nitrification, with soil moisture, pH, and electrical conductivity identified as key determinants of community composition.
The impact of different preceding crops on soil nitrogen structure and nitrogen cycling in tobacco-planting soil
Researchers examined how the crop grown in a field before tobacco affects soil nitrogen levels and the microbial genes responsible for nitrogen cycling, finding that barley and rapeseed as preceding crops significantly increased available nitrogen while suppressing key nitrification genes. The results suggest crop rotation can meaningfully shape soil nutrient dynamics and microbial communities, with implications for sustainable tobacco farming.
Effect of Nitrogen Addition on Tiger Nut (Cyperus esculentus L.) Rhizosphere Microbial Diversity and Drive Factions of Rhizosphere Soil Multifunctionality in Sandy Farmland
Not relevant to microplastics — this study investigates how nitrogen fertilizer addition affects rhizosphere microbial diversity and soil multifunctionality in tiger nut crops grown in sandy farmland.
Maize root-soil microbial interactions and their effects on soil health and yield
Researchers examined interactions between maize roots and soil microbial communities, investigating how root-microbe dynamics influence soil health indicators and crop yield. The study found specific rhizosphere microbial associations that promote nutrient availability and plant productivity.
Inter-phylum negative interactions affect soil bacterial community dynamics and functions during soybean development under long-term nitrogen fertilization
Researchers found that the growth stage of soybean plants had a stronger influence on soil bacterial communities than 16 years of nitrogen fertilization, while fertilization more strongly shaped nitrogen-processing gene activity. Negative interactions between certain bacterial groups helped explain how soil microbial communities change over a crop's growing season.
Differences in the Microbial Composition and Function of the Arundo donax Rhizosphere Under Different Cultivation Conditions
Researchers compared the microbial communities in the root zones of giant reed (Arundo donax) grown in hydroponic versus soil conditions. The study found that hydroponic cultivation resulted in lower microbial diversity but higher abundances of nitrogen-fixing and photosynthetic bacteria, providing insights into how cultivation methods influence root-associated microorganism communities.
Linear responses of soil microbiomes, metagenomic and metabolomic functioning across ecosystems along water gradients in the Altai region, northwestern China
Researchers analyzed soil microbial communities, their genetic functions, and metabolic profiles across four ecosystems along a water gradient in the Altai region of China. Microbial diversity and carbon and nitrogen cycling functions increased linearly with soil moisture, demonstrating how hydrology shapes ecosystem-level microbial processes.

This review examines how different fertilizer types — chemical, organic, and compound — affect soil microbial communities, summarizing research on how fertilizer-induced changes in microbial diversity and function influence nutrient cycling and crop yield.
Metagenomics reveals the effect of long-term fertilization on carbon cycle in the maize rhizosphere
Metagenomics analysis of maize rhizosphere soil revealed that long-term chemical nitrogen fertilizer treatments increased abundance of genes regulating the reductive citrate cycle for carbon fixation, while straw return treatments increased carbon degradation gene abundance.

Polyethylene microplastic and soil nitrogen dynamics: Unraveling the links between functional genes, microbial communities, and transformation processes
Researchers conducted a six-month experiment to understand how polyethylene microplastics in soil affect nitrogen cycling, a process critical for soil fertility and plant nutrition. They found that while total nitrogen levels stayed stable, microplastics significantly altered the forms of nitrogen present by increasing ammonium and nitrate while decreasing dissolved organic nitrogen. The study suggests that microplastics reshape soil microbial communities and their nitrogen-processing activities, potentially disrupting the natural nutrient balance in agricultural soils.
