Estimates of the rate of nonsymbiotic fixation of N 2 15 were calculated on an area basis for several natural woodland and cultivated field soils. Results supported the conclusion that much of the nitrogen gain in the field may be associated with periods or regions of anaerobiosis, or with localized available energy sources. There was agreement with many earlier conclusions drawn from nitrogen balance experiments.
