Special Issue Information

The coupled cycles of nitrogen (N) and carbon (C) form the fundamental backbone of Earth's biogeochemistry, governing the structure and function of ecosystems and the global climate; these interactions/feedbacks are very critical yet complex processes. N availability has an impact on the C cycle, though this remains to be fully understood. Moderate N levels can enhance the absorption of CO2 by plants, increasing the input of plant-derived C into soil. However, excessive N inputs may lead to soil acidification, stimulating biodiversity loss and greenhouse gas emissions and thereby weakening long-term C storage capacity. Understanding these delicate N-C interactions is therefore paramount for predicting climate change and developing sustainable environmental policies.

This Special Issue in Nitrogen aims to explore recent advances in our understanding of how N-C interactions influence biogeochemical cycles—particularly carbon sequestration—in Earth's ecosystems, such as croplands, forests, grasslands, and wetlands. Topics of interest include, but are not limited to, the following:

Investigating the microbial mechanisms (e.g., microbial communities, functional genes, and metabolites) regulating N-C cycling processes within Earth's ecosystems.

Exploring the effects of N inputs, transformations and availability on C fate (e.g., C fixation, stability, and emissions) and examining potential variations across different ecosystems.

Understanding the responses of N-C interactions to climate change factors (e.g., warming, precipitation, elevated CO₂) and anthropogenic disturbance measures (e.g., agricultural management, land use change).

We welcome original research, comprehensive reviews (meta-analysis), perspectives, and case studies exploring the coupling mechanism of N-C interactions within Earth's ecosystems, aiming to provide scientific evidence for mitigating global climate change.
