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

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.<br>Note:1 Af, <i>Artemisia frigida</i>, Cs, <i>Cleistogenes squarrosa</i>, Cl., <i>Carex spp</i>, Ic, <i>Ixeris chinensis </i>subsp<i>.
