Alfalfa fields with different stand ages alters soil inorganic nitrogen dynamics through shifts in nitrogen-cycling functional genes across growth stages [PDF]

Frontiers in Microbiology
IntroductionAlfalfa cultivation is associated with soil nitrogen availability and microbial nitrogen-cycling functional potential. However, how soil inorganic nitrogen and nitrogen-cycling functional genes vary with alfalfa stand age across growth stages

Responses of Soil Nitrogen-Cycling Microbial Communities and Functional Potential to Grazing Intensities in Alpine Meadows [PDF]

Microorganisms
Although grazing is a key driver of nitrogen cycling in alpine meadow soils, a systematic understanding of how different grazing intensities shape the structure and functional potential of soil nitrogen-cycling microbial communities remains lacking.

The microecological mechanism of Cordyceps chanhua promoting soil nitrogen cycling [PDF]

Environmental Microbiome
Background The nitrogen cycle is crucial to the function of the Earth’s biosphere. Entomogenous fungi have been proven to promote nitrogen metabolism and cycling in host insects, and transfer nitrogen from insects to soil.

The hidden potential of archaea in carbon and nitrogen cycling in agricultural soils: a review [PDF]

Frontiers in Microbiology
The soil microbiome drives soil nutrient cycling and is intrinsically linked to plant productivity in agriculture. Archaea are members of many soil microbiomes and play important roles in nutrient cycling, particularly in the carbon and nitrogen cycle ...

Interaction Mechanisms Among Soil Environmental Factors, Microbial Communities, and Nitrogen-Cycling Functional Genes in Cool-Climate Maize Fields [PDF]

Microorganisms
Cool-climate maize fields are characterized by low soil temperatures, strong seasonal hydrothermal fluctuations, and peat-influenced soil profiles, which may lead to patterns of nitrogen (N) cycling distinct from those in conventional agricultural soils.

Mikania micrantha invasion restructures rhizosphere nitrogen cycling through enzyme activation, microbial recruitment, and allelopathic regulation [PDF]

Microbiome
Background Plant invasions profoundly influence terrestrial ecosystems by reshaping nutrient cycling processes. However, the mechanisms through which invasive plants such as Mikania micrantha modulate soil nitrogen (N) cycling and microbial communities ...

Characterizing nitrogen cycling microorganisms and genes in sediments of the Three Gorges Reservoir. [PDF]

PLoS ONE
Microorganisms play a central role in driving the biogeochemical cycles in lakes (reservoirs). This study aims to refine the microbial-driven nitrogen cycle processes in the sediments of the Three Gorges Reservoir and assess the overall state of nitrogen

Protozoa-driven micro-food webs shaping carbon and nitrogen cycling in reservoir ecosystems [PDF]

Environmental Microbiome
Protozoa-driven micro-food webs are pivotal regulators of microbial community structure and carbon–nitrogen cycling. By mediating trophic cascades that regulate bacterial and algal populations, protozoa influence nutrient remineralization and energy flow.

The spatial distribution and biogeochemical drivers of nitrogen cycle genes in an Antarctic desert

Frontiers in Microbiology, 2022
Antarctic deserts, such as the McMurdo Dry Valleys (MDV), represent extremely cold and dry environments. Consequently, MDV are suitable for studying the environment limits on the cycling of key elements that are necessary for life, like nitrogen.

Research status and trend of coupling between nitrogen cycle and arsenic migration and transformation in groundwater systems

Shuiwen dizhi gongcheng dizhi, 2022
The coexistence of ammonium, arsenic and dissolved iron in groundwater is a common phenomenon in aquifer systems. They have a strong interaction and affect the nitrogen cycling and the migration and transformation of arsenic in groundwater systems. Based
