摘要：
The influence of N-fertilization and crop species on the release of the greenhouse gas N2O was investigated at two sites in northern Germany from June 1994 till October 1996. The N2O release was measured daily. The results were correlated to the nitrate and ammonia content of the soil as well as to fertilizer type, crop species and soil moisture. The results of the investigations showed no effect of N-fertilizer type or crop species on the N2O release. Main result of this work is that lowering the N fertilization to about 50% of the standard could reduce the N2O release.
