Effects of short-term nitrogen and phosphorus addition on leaf stoichiometry of a dominant alpine grass.

ABSTRACT: The effects of increasing nitrogen (N) and phosphorus (P) deposition on the nutrient stoichiometry of soil and plant are gaining improving recognition. However, whether and how the responses of N cycle coupled with P of the soil-plant system to external N and P deposition in alpine grassland is still unclear. A short-term external N and P addition experiment was conducted in an alpine grazing grassland in the KunLun Mountain to explore the effects of short-term N and P addition on the nutrient stoichiometry in soil and plant. Different rates of N addition (ranging from 0.5 g N m^-2 yr^-1 to 24 g N m^-2 yr^-1) and P addition (ranging from 0.05 g N m^-2 yr^-1 to 3.2 g P m^-2 yr^-1) were supplied, and the soil ava
