ClearShort‐term effects of mineral and combined mineral‐organic fertilization in soil microbial communities
A one-year fertilization trial in a Qinghai-Tibet Plateau greenhouse found that both mineral and combined mineral-organic fertilization increased bacterial richness and decreased fungal diversity compared to unfertilized soil, with available phosphorus as the primary driver of microbial community structure changes.
Application of Organic Fertilizer Changes the Rhizosphere Microbial Communities of a Gramineous Grass on Qinghai–Tibet Plateau
Researchers examined how organic fertilizer application altered rhizosphere microbial communities in a gramineous grass, finding significant shifts in bacterial diversity and composition that may influence nutrient cycling and soil health in grassland ecosystems.
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.
Linking bacterial and fungal assemblages to soil nutrient cycling within different aggregate sizes in agroecosystem
Researchers investigated how bacterial and fungal microbial assemblages within four different soil aggregate sizes correlate with nutrient cycling in rice fields in Southern China, finding that deterministic processes govern bacteria while stochastic processes govern fungi, and that macroaggregates showed stronger regulation of carbon, nitrogen, and phosphorus cycling by soil properties than microaggregates.
Microplastics reduce soil microbial network complexity and ecological deterministic selection
Researchers found that microplastics reduce soil microbial network complexity and shift community assembly from deterministic to more stochastic processes, suggesting that microplastic pollution may fundamentally alter microbial ecological interactions in terrestrial systems.
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.
Clomazone impact on fungal network complexity and stability
Researchers investigated how the herbicide clomazone affected soil fungal network complexity and stability, finding that while node count decreased by 12-42, average degree and network density increased under clomazone treatment, and overall network robustness improved while vulnerability decreased, indicating increased but restructured fungal network stability.
Soil Microbial Communities in Pseudotsuga sinensis Forests with Different Degrees of Rocky Desertification in the Karst Region, Southwest China
Researchers studied how increasing levels of rocky desertification in karst forests in southwest China affect soil microbial communities. They found that bacterial diversity declined significantly as desertification worsened, while fungal communities showed more resilience. Key soil properties including pH, organic carbon, and available nitrogen were identified as the main drivers shaping these microbial community shifts.
Soil metagenomics reveals the effect of nitrogen on soil microbial communities and nitrogen-cycle functional genes in the rhizosphere of Panax ginseng
Researchers studied how different levels of nitrogen fertilizer affect the soil microbial communities around ginseng roots. They found that moderate nitrogen boosted beneficial microbes and improved ginseng yields, while excessive nitrogen decreased soil pH, reduced microbial diversity, and increased disease-causing organisms. The study highlights the importance of balanced fertilizer use for maintaining healthy soil ecosystems in agricultural settings.
Structural and Functional Characteristics of Soil Microbial Communities in Forest–Wetland Ecotones: A Case Study of the Lesser Khingan Mountains
Researchers examined soil microbial communities across a forest-to-wetland gradient in China's Lesser Khingan Mountains, comparing mixed forest, conifer forest, wetland edge, and natural wetland. Natural wetland soils harbored the most distinct bacterial communities, driven primarily by high organic matter, nitrogen, and phosphorus content.
Influence of different irrigation methods on the alfalfa rhizosphere soil fungal communities in an arid region
Researchers examined how traditional flood irrigation versus drip irrigation methods affect fungal diversity, community structures, and ecological functions in alfalfa rhizosphere soils in the arid Xinjiang region of China, finding that irrigation method significantly shapes soil fungal communities.
Biodegradable microplastics enhance soil microbial network complexity and ecological stochasticity
Researchers found that biodegradable microplastics increased soil microbial network complexity and shifted community assembly toward more stochastic processes, suggesting they reshape soil ecosystems differently than conventional plastics.
Root carbon inputs outweigh litter in shaping grassland soil microbiomes and ecosystem multifunctionality
Researchers analyzed 13 years of field data from a semi-arid grassland and found that carbon inputs from plant roots matter more than leaf litter in sustaining soil microbial diversity and overall ecosystem health. Removing plants caused greater microbial and functional declines than removing surface litter, underscoring the hidden importance of below-ground carbon in maintaining healthy soils.
Shifts in maize microbial communities and networks are correlated with the soil soil chemical property under different fertilization regimes
A corn field experiment compared how different fertilizers — chemical versus organic — shaped soil microbial communities and their interaction networks. Organic fertilizers altered both the diversity and connections between soil microbes, which has implications for soil health and agricultural sustainability.
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.
Different Distribution of Core Microbiota in Upper Soil Layer in Two Places of North China Plain
Researchers compared the composition and distribution of core soil microbiota in upper soil layers at two locations on the North China Plain, examining how habitat and dominant plant species shape bacterial community structure relevant to nutrient cycling and carbon storage. The study found meaningful differences in microbial community composition between the two sites, reflecting local environmental influences.
Soil-Microbial CNP Content and Ecological Stoichiometry Characteristics of Typical Broad-Leaved Tree Communities in Fanjing Mountain in Spring
This paper is not about microplastics; it examines soil microbial carbon, nitrogen, and phosphorus stoichiometry across four subtropical forest types in Fanjing Mountain, China, to understand nutrient cycling and microbial nutrient limitations.
Effect of Nitrogen Addition on Tiger Nut (Cyperus esculentus L.) Rhizosphere Microbial Diversity and Drive Factions of Rhizosphere Soil Multifunctionality in Sandy Farmland

Soil nutrient heterogeneity alters productivity and diversity of experimental plant communities under multiple global change factors

Rhizosphere Soil Microbial Community Under Ice in a High-Latitude Wetland: Different Community Assembly Processes Shape Patterns of Rare and Abundant Microbes
Researchers investigated community assembly processes shaping rhizosphere microbial communities under ice in a high-latitude wetland, using 16S rRNA gene and ITS sequencing for two plant species during ice-covered and ice-free stages. They found bacterial communities were primarily shaped by homogeneous selection and dispersal limitation across both stages, while fungal communities were dominated by dispersal limitation under ice and ecological drift during the ice-free period.
