between aluminium and C (b), K (c) and Ca (d) contents. Asterisks indicate significant differences (P<0.05) between clearfelling (T100)

and the other treatments in (a). Error bars represent SD

Supplementary Data Fig 2 Nutrients in the decomposing needles released (positive values) or absorbed (negative values) where Block
9
had a significant effect. Obtained as (Entry et al., 1991): N t=C0 - [(1- W) Ct], where Nt is the amount of nutrient released or absorbed at
10
time t (mg g-1), C0 is the initial nutrient litter concentration (mg g-1), W is weight loss at time t (%) and Ct is the nutrient concentration
11
litter at time t (mg g-1). Lower case letters indicate significant differences (P<0.05).
