Fig. 2

Effect of experimental N addition on above- ((a) MS, (b) TS, (c) DS) and below-ground biomass ((d) MS, (e) TS, (f) DS) of three temperate steppes from 2017 to 2018. Lowercase letters represent significant differences among different treatments in 2017 at the 0.05 level, while uppercase letters represent significant differences among treatments in 2018 at the 0.05 level. Data show the mean ± standard error (n = 3) (same as below)
