This study was conducted in broadleaved Korean pine forest in Changbai Mountains to explore the effects of nitrogen deposition on soil respiration. The levels of nitrogen deposition were control( CK),low nitrogen( 23 kg·hm- 2·a- 1),medium nitrogen( 46 kg·hm- 2·a- 1) and high nitrogen( 69 kg·hm- 2·a- 1) by adding urea at the beginning of June,July and August since 2011. Soil respiration was measured by three to four times at mid month from May to October by using infrared gas analyzer. Soil respiration showe...
