Long-term nitrogen deposition enhances microbial capacities in soil carbon stabilization but reduces network complexity.

ABSTRACT:

Background

Anthropogenic activities have increased the inputs of atmospheric reactive nitrogen (N) into terrestrial ecosystems, affecting soil carbon stability and microbial communities. Previous studies have primarily examined the effects of nitrogen deposition on microbial taxonomy, enzymatic activities, and functional processes. Here, we examined various functional traits of soil microbial communities and how these traits are interrelated in a Mediterranean-type grassland administrated with 14 years of 7 g m^-2 year^-1 of N amendment, based on estimated atmospheric N deposition in areas within California, USA, by the end of the twenty-first century.

Results

Soil microbial communities were significantly altered by N deposition. Consistent with higher ab
