Atmospheric nitrogen fixation in the rice rhizosphere was determined under in situ conditions of growing flooded rice using the N-15 isotope method. The whole plant growing in a pot at a reproductive stage was placed in a specially designed glass container and exposed to a ^<15>N_2 atmosphere. The amounts of total nitrogen fixed in the rice rhizosphere under the experimental conditions were 1366,592,878,and 698 μg per pot containing 0.4 kg of soil during ^<15>N_2 exposure for 7 to 13 days in the four experiments conducted in this study. It was also found that the nitrogen fixed in the rice rhizosphere was translocated into other plant parts. Nineteen to 25% of the total atmospheric nitrogen fixed in the rice rhizosphere was found in the roots, leaves and stems, and ears of the rice plants during the ^<15>N_2 exposure period.
