An in situ device for assaying biological nitrogen fixation in flooded rice soils, using the acetylene reduction method, was developed. Diurnal variations in acetylene reduction by an inoculated field plot and by laboratory-grown cultures of nitrogen-fixing algae showed a prominent single-peak pattern of nitrogenase activity. The peak occurred at mid-day for laboratory-grown algae and at late afternoon for the algae grown in the field plot. Some nitrogenase activity was noted during the night… CONTINUE READING
