Abstract:Previous studies have demonstrated changes in plant growth and
reproduction in response to nutrient availability, but how
investigations of such responses to multiple levels of nutrient
enrichment remains unclear. In this study, we manipulated nitrogen (N)
and phosphorus (P) availability to examine seed production responses to
three levels each of N and P addition in a factorial experiment: no N
addition (0 g N m-2 yr-1), low N addition (10 g N m-2 yr-1), high N
addition (40 g N m-2 yr-1), and no P addition (0… Show more
