Effects of experimental nitrogen and phosphorus addition on litter decomposition in an old-growth tropical forest.

The responses of litter decomposition to nitrogen (N) and phosphorus (P) additions were examined in an old-growth tropical forest in southern China to test the following hypotheses: (1) N addition would decrease litter decomposition; (2) P addition would increase litter decomposition, and (3) P addi...
