Short summary
The Qinghai–Tibet Plateau is sensitive to climate change. We documented seasonal and interannual dynamics of soil microbial and available N in an alpine meadow in this region. Consistently increasing trends of microbial biomass and available N pools were observed during the nongrowing season. Significant shifts in microbial communities largely contributed to microbial reduction during soil thaw. Divergent seasonal dynamics of different N forms showed a complementary nutrient supply pattern.
