Fig. 1From: Effects of thinning intensity on nutrient concentration and enzyme activity in Larix kaempferi forest soilsSoil carbon concentration (TC; a), soil nitrogen concentration (TN; b), and carbon and nitrogen ratio (CN ratio; c) in the control, 20 % thinning (T20), and 30 % thinning (T30) at a depth of 0–10 cm 3 years after thinning. Different letters indicate significant difference among the three thinning intensities (n = 3; P = 0.05). Error bars represent the standard errorsBack to article page
