Table 1 Results from an ANOVA analysis evaluating the effect of species, nitrogen (N) sources, N forms, N levels, and their interactive effects on N uptake rates during treatment periods. Italics indicates p < 0.05.

From: Organic nitrogen uptake is a significant contributor to nitrogen economy of subtropical epiphytic bryophytes
