Table 3 P values for repeated measures ANOVA concerning the effects of sampling year (SY), logging residue loading treatments (T), and their interactions on soil nutrients after 5 years (2001), 10 years (2006), and 19 years (2015).

From: Long-term logging residue loadings affect tree growth but not soil nutrients in Pinus contorta Doug. ex Loud. forests

The comparisons among the three sampling years were conducted using Tukey’s test. The different letters in the same column mean significant difference among the sampling years after treatments. The mean difference is significant at the 0.05 level, n = 5
