About this Research Topic
Human activities including burning fossil fuels and using nitrogen fertilizers are significantly altering the manner and rate of atmospheric nitrogen deposition to terrestrial ecosystems. Ecosystem type, nitrogen deposition rate and type, and duration of nitrogen input have significant impacts on both aboveground and belowground ecosystems. Sustained nitrogen deposition could increase soil nitrogen efficiency and lead to soil acidification. Moreover, deposition may affect the enzymatic activities of soil microorganisms and soil respiration. Nitrogen deposition could also affect the diversity, community composition, and net primary productivity of aboveground vegetation.
Given the current suite of ecosystem impacts from nitrogen deposition, it is important to study the response of soil and vegetation, to nitrogen deposition and the plant-soil interactions associated with nitrogen deposition. Appropriate studies can reveal the ecological impacts caused by nitrogen deposition to better understand and assess the ecological risks of nitrogen deposition worldwide. They can also provide a scientific basis for the management and sustainable development of terrestrial ecosystems.
This Research Topic aims to investigate investigations on the effects and mechanisms of nitrogen deposition on plant and soil microbial community structure and function through field investigations, controlled experiments, and model development. We welcome submissions of original research papers, reviews, and methods, including (but not limited to) research on the following sub-themes:
• Effects of nitrogen deposition on extracellular enzymatic activities of soil microorganisms and soil respiration.
• Effects of nitrogen deposition on species diversity and functional diversity of soil microorganisms.
• Effects of nitrogen deposition on plant functional traits.
• Effects of nitrogen deposition on decomposition of plant litter.
• Effects of nitrogen deposition on plant community diversity.
• Effects of nitrogen deposition on plant community productivity.
• Effects of nitrogen deposition on community succession.
• Effects of nitrogen addition on plant-soil interactions.
• Effects of nitrogen deposition on carbon sequestration in ecosystems.
• Effects of nitrogen deposition on ecosystem element (C, N, P) cycles.
• Studies on different nitrogen deposition scenarios and multi-factor composite effects.
• Plant-plant interactions under altered N deposition
