Organic fertilizers altered both the diversity and connections between soil microbes, which has implications for soil health and agricultural sustainability.
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.
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.

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.
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.
Soil Greenhouse Gas Emissions and Nitrogen Dynamics: Effects of Maize Straw Incorporation Under Contrasting Nitrogen Fertilization Levels
Not relevant to microplastics — this study examines how maize straw incorporation into soils with different nitrogen fertilization histories affects greenhouse gas emissions and nitrogen cycling in agricultural fields.
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.
Linking rhizospheric microbiota and metabolite interactions with harvested aboveground carbon and soil carbon of lakeshore reed wetlands in a subtropical region
Researchers studied how soil microorganisms and plant-produced chemicals in wetland reed rhizospheres interact to influence carbon storage in lakeside wetlands. Understanding these relationships helps protect wetlands as important carbon sinks in the face of climate change.
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.
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.
Ecological Responses of Maize Rhizosphere to Antibiotics Entering the Agricultural System in an Area with High Arsenicals Geological Background
Researchers investigated how antibiotics from cow manure enter a maize cropping system in an area with naturally high arsenic levels, finding that oxytetracycline and sulfadiazine significantly altered soil nutrient conditions in the rhizosphere while interactions with arsenic and other metals showed no significant differences.
