Interactive effect of non-growing and growing seasons precipitation addition on plants and soil stoichiometry in a semi-arid steppe

This data primarily focuses on the interactive effects of snow and rainfall augmentation on plant and soil stoichiometry. The effect of precipitation addition is examined across both non-growing (NP) and growing seasons (GP) to elucidate the interaction effect.Note:1 Af, Artemisia frigida, Cs, Cleistogenes squarrosa, Cl., Carex spp, Ic, Ixeris chinensis subsp.
