The objective of this study was to determine the effects of fertilizer types on total soil and heterotrophic respiration in red pine stands. Fertilizer (NPK=113:150:37 kg/ha/yr; PK=150:37 kg/ha/yr) was applied for three years (April 2011, April 2012, April 2013) in approximately 40-year-old natural red pine stands of the Wola National Experimental Forest, southern Korea. Total and heterotrophic soil respiration rates were monthly monitored for three years (April 2011 to March 2014). Mean annual total soil respiration rates (g CO₂ m²/h) were 0.47 for the NPK, followed by 0.45 for the PK and 0.44 for the control treatments. Similarly, heterotrophic soil respiration rates (g CO₂ m²/h) were 0.33 for the NPK, followed by 0.31 for the PK and 0.31 for the control treatments. These results suggest that mean annual total soil respiration rates were little affected by the change in nutrient availability with compound types (NPK or PK) of fertilizer in red pine stands. It is evident that heterotrophic respiration rates were independent of compound types of fertilizer because soil temperature is likely to control heterotrophic respiration activity.
