Field studies using a chamber technique to measure emissions of nitrous oxide (N 2 O) showed that the N 2 O emissions induced by fertilization of soil with anhydrous ammonia (180 kg N ha −1 ) were markedly reduced by addition of nitrapyrin [2‐chloro‐6‐(trichloromethyl)‐pyridine] to this fertilizer. The emission of N 2 O induced by application of anhydrous ammonia in the fall was reduced 63% by addition of nitrapyrin at the rate of 0.56 kg ha −1 . The corresponding reduction when nitrapyrin was added to anhydrous ammonia applied in the spring was 87%. These observations indicate that nitrapyrin has potential value for reduction of the N 2 O emissions induced by nitrogen fertilization of soils and the possible adverse effects of these emissions on our climate.
