Responses of plant carbon and nitrogen assimilations to nitrogen addition in a subtropical forest: Canopy addition vs. understory addition

Ecotoxicology and Environmental Safety, 2023
The global atmospheric nitrogen (N) deposition has intensified in recent years, resulting in a complex impact on forest ecosystems. This study investigated the effects of canopy (CAN) and understory additions of N (UAN) on leaf carbon (C) and N ...

Nitrogen addition alters soil microbial community structure and decrease nitrogen cycling gene abundance in acidic macadamia orchard soils [PDF]

Frontiers in Microbiology
Nitrogen addition can alter soil microbial communities and regulate nitrogen cycling processes. However, the role of nitrogen-induced soil acidification in modulating nitrogen cycling in macadamia orchard soils remains poorly understood.

Nitrogen saturation drives shifts in response patterns of non-structural carbohydrate pools in a meadow steppe after ceasing nitrogen addition [PDF]

Frontiers in Plant Science
Non-structural carbohydrates (NSC) in grassland plants represent the outcome of carbon (C) allocation processes and serve as integrative indicators of plant C status and nutrient balance.

Response of Soil Bacteria to Short-Term Nitrogen Addition in Nutrient-Poor Areas [PDF]

Microorganisms
Increasing nitrogen (N) addition induces soil nutrient imbalances and is recognized as a major regulator of soil microbial communities. However, how soil bacterial abundance, diversity, and community composition respond to exogenous N addition in ...

Antagonistic interaction between biochar and nitrogen addition on soil greenhouse gas fluxes: A global synthesis

GCB Bioenergy, 2021
Both biochar and nitrogen (N) addition have been proposed for enhancing plant productivity and increasing carbon (C) sequestration. Although numerous studies have been conducted to examine responses of soil greenhouse gas (GHG) fluxes to biochar or N ...

Transcriptome Profiling and Chlorophyll Metabolic Pathway Analysis Reveal the Response of Nitraria tangutorum to Increased Nitrogen

Plants, 2023
To identify genes that respond to increased nitrogen and assess the involvement of the chlorophyll metabolic pathway and associated regulatory mechanisms in these responses, Nitraria tangutorum seedlings were subjected to four nitrogen concentrations (N0,
