Measurement of nitrous oxide emissions from upland fields in Thailand




Nitrous oxide emissions from upland soils were measured during a period of one year by the closed chamber method at four experimental sites in Thailand. Two treatments consisting of the application and absence of application of nitrogen fertilizer were set in triplicate at each experimental site. The total amount of nitrous oxide emitted throughout the maize cultivation period ranged from 0.08 to 0.48% of applied nitrogen fertilizer and these rates not significantly different from those recorded in the temperate zone.
