Grasslands contain enormous soil organic carbon (SOC) reserves, and even minor
fluctuations may have a great effect on the climate. N, P and S in soil organic matter (SOM) …

Eutrophication is a major driver of species loss in plant communities worldwide. However,
the underlying mechanisms of this phenomenon are controversial. Previous studies have …

Both nitrogen (N) and phosphorus (P) enrichment are known to impact plant diversity
globally. Recent studies suggest that P enrichment may be as important, or even more …

Atmospheric nitrogen (N) deposition is enriching soils with N across biomes. Soil N
enrichment can increase plant productivity and affect microbial activity, thereby increasing …

Anthropogenic activities and atmospheric deposition have increased the nitrogen (N) and
phosphorus (P) inputs to terrestrial ecosystems, which can significantly alter ecosystem …

Soil microbial carbon use efficiency (CUE), defined as the ratio between carbon (C)
allocated to growth and C taken up by microorganisms, is pivotal for the understanding of C …

Determining the abundance of N isotope (δ15N) in natural environments is a simple but
powerful method for providing integrated information on the N cycling dynamics and status …

Increased available soil nitrogen can increase biomass, lower species richness, alter soil
chemistry and modify community structure in herbaceous ecosystems worldwide. Although …

Aims Nitrogen (N) fertilizer is applied to the soil to increase the nutrient level and plant
productivity, but the effects of N addition on the soil microbial community diversity and …

Humus (HS) is an important component of soil organic matter. Humic acid (HA) and fulvic
acid (FA) are two of the most important components of HS, as they substantially affect …
