Outline of Final Research Achievements

We conducted soil incubation experiments with soils amended with various pelleted manure fertilizers (PM) to elucidate mechanisms and characteristics of nitrous oxide (N2O) emission from PMs. We found that N2O emission from soils amended with PM was generally higher than that amended with chemical fertilizers. However, the N2O emission was decreased by addition of ammonium sulfate, urea, or small amount of lime nitrogen. The N2O emission was also decreased by covering the soil with polyethylene film (soil mulching) after amendment of PM for two weeks. Decrease in the N2O emission by the addition of ammonium sulfate or urea, or by the soil mulching indicated that N2O was produced mainly via denitrification process inside the pellets, and that it could be decreased remarkably by restraining denitrification. On the other hand, decrease in the N2O emission by the addition of lime nitrogen indicated that N2O emission could also be decreased to some extent by restraining nitrification.
