Nitrogen response efficiency increased monotonically with decreasing soil resource availability: a case study from a semiarid grassland in northern China
The concept of nutrient use efficiency is central to understanding ecosystem functioning
because it is the step in which plants can influence the return of nutrients to the soil pool and
the quality of the litter. Theory suggests that nutrient efficiency increases unimodally with
declining soil resources, but this has not been tested empirically for N and water in
grassland ecosystems, where plant growth in these ecosystems is generally thought to be
limited by soil N and moisture. In this paper, we tested the N uptake and the N use efficiency …
