Annual soil respiration (R) and its % decreased for each year in the pine forest (PF), the mixed conifer and broadleaf forest (MF) and the broadleaved forest (BF) under different SAR treatments (mean ± standard deviations).

<p>n = 3 for all the treatments. Mean values within a row with different lowercase letter have significant treatment differences at <i>p = </i>0.05 level. The treatments are: CK = control, T1 = pH 4.0, T2 = pH 3.5, T3 = pH 3.0. % decreased = 100 ((R of the CK treatment – R of each treatment)/R of the CK treatment) % (in the same time period); negative values within the column means % increased. The 1^st year: April 2010 to March 2011; The 2^nd year: April 2011 to March 2012; Mean: April 2010 to March 2012. Unit: kgCO2 m⁻² yr⁻¹ for R.</p

Relationship of soil respiration rate with soil temperature or soil moisture under different SAR treatments in the pine forest (PF), the mixed conifer and broadleaf forest (MF) and the broadleaved forest (BF).

<p>n = 126 for all the treatments. The treatments are: CK = control, T1 = pH 4.0, T2 = pH 3.5, T3 = pH 3.0.</p
