我们使用了一个自动化的通量监测系统，以测量N2O，NO和NO2通量从1999年5月和2000年9月之间的Andisol字段。在1999年和2000年，小白菜和菠菜分别种植了1.5个月。我们在每个地块上施用了15 g N m−2的油饼、牛粪、鱼粉、干牛粪或尿素。在整个栽培期间，有机地块的N2O和NO排放量分别为2.55 mg N m−2至35.2 mg N m−2和2.48 mg N m−2至22.5 mg N m−2。尿素图的值分别为10.9 mg N m−2至21.1 mg N m−2和52.0 mg N m−2至105 mg N m−2。我们估计，日本Andisol田有机肥的N2O排放量与化肥相当。
We used an automated flux monitoring system to measure N2O, NO, and NO2 fluxes from an Andisol field between May 1999 and September 2000. Pac choi and spinach were cultivated for 1.5 months in 1999 and 2000, respectively. We applied 15 g N m−2 of oilcake, cattle manure, fishmeal, dried cattle excreta, or urea to each plot. N2O and NO emissions from organic plots over the cultivation period were 2.55 mg N m−2 to 35.2 mg N m−2, and 2.48 mg N m−2 to 22.5 mg N m−2, respectively. Those from the urea plot were 10.9 mg N m−2 to 21.1 mg N m−2, and 52.0 mg N m−2 to 105 mg N m−2, respectively. We estimated that N2O emission from organic fertilizer is equivalent to that from chemical fertilizer application on Japanese Andisol field.
