Data for 'Resource availability alleviates microbial relative C limitation but aggravates N and P limitations from dry to humid grasslands'

Soil microbial resource limitations are linked to microbial metabolism and biogeochemical processes, reflecting the microbial demand for carbon (C), nitrogen (N), and phosphorus (P). However, understanding the confounding effects of climatic, edaphic, plant, and microbial factors on microbial resource limitations at large spatial scales remains limited. Here, we explored the patterns and drivers of microbial resource limitations along a 3000-km transect on the Tibetan Plateau using vector analysis of enzymatic activity.
