| Abstract | Determining the abundance of N isotope (delta N-15) in natural environments is a simple but powerful method for providing integrated information on the N cycling dynamics and status in an ecosystem under exogenous N inputs. However, whether the input of different N compounds could differently impact plant growth and their N-15 signatures remains unclear. Here, the response of N-15 signatures and growth of three dominant plants (Leymus chinensis, Carex duriuscula, and Thermopsis lanceolata) to the addition of three N compounds (NH4HCO3, urea, and NH4NO3) at multiple N addition rates were assessed in a meadow steppe in Inner Mongolia. The three plants showed different initial foliar delta N-15 values because of differences in their N acquisition strategies. Particularly, T. lanceolata (N-2-fixing species) showed significantly lower N-15 signatures than L. chinensis (associated with arbuscular mycorrhizal fungi [AMF]) and C. duriuscula (associated with AMF). Moreover, the foliar delta N-15 of all three species increased with increasing N addition rates, with a sharp increase above an N addition rate of similar to 10 g N m(-2) year(-1). Foliar delta N-15 values were significantly higher when NH4HCO3 and urea were added than when NH4NO3 was added, suggesting that adding weakly acidifying N compounds could result in a more open N cycle. Overall, our results imply that assessing the N transformation processes in the context of increasing global N deposition necessitates the consideration of N deposition rates, forms of the deposited N compounds, and N utilization strategies of the co-existing plant species in the ecosystem. |
