Summary The amount of nitrogen gas, oxygen, hydrogen, and methane in soil samples from a submerged rice field was determined using the modified Koyama's apparatus and gas chromatography. Soils planted to rice had significantly larger amounts of nitrogen gas than unplanted soils. The amount of N2 in a field soil increased after transplanting and reached a maximum at tillering. The amount of N2 in unplanted submerged soils did not increase significantly during the same period.
