The dataset of Life history strategies of grassland soil microbiomes drive their adaptability to resources and stress mainly by niche conservatism under nitrogen deposition

Atmospheric nitrogen (N) deposition usually alters the ratio of resources to stress in local environments and has important impacts on soil microbiomes. The adaptability of microbiomes to resources and stress can be highly reflected by high yield (Y)-resource acquisition (A)-stress tolerance (S) life history strategies, which successfully link microbial processes with environmental changes but still lack comprehensive analysis under the N deposition scenario. In this study, we analyze the variation of bacterial taxa, bacterial functional potential, and microbial traits under different N levels of ammonium nitrate (AN) and urea (AU) addition at a temperate grassland in Inner Mongolia. This dataset contained 96 metagenomic data, 96 16S rRNA gene amplicon data, and 96 ITS rRNA gene amplicon data.
