    Abstract Chemical elements, such as carbon (C), nitrogen (N) and phosphorus (P), are major limiting nutrients in arid and semiarid grasslands and their stoichiometry (C:N:P) is a very important ratio to determine. In addition, it is critical to understand how plant stoichiometry responds to multiple environmental factors at the species level. In this study, we conducted a greenhouse experiment to investigate the effects of salt stress (4 g NaCl/kg soil), drought (35% of the soil water holding capacity) and N addition (10 g N/m2), as well as their interactions, on C, N and P concentrations and C:N:P ratios in two dominant… More >
