| Outline of Final Research Achievements |
N2O is a powerful greenhouse gas and an ozone depleting substance. Agriculture is the largest source of N2O anthropogenic emission. It is important to elucidate the N2O production processes in agricultural soil, and to develop mitigation options.
N2O is thought to be mainly produced via microbial nitrification and denitrification, although the actual production process is not clear in site fields. The aim of study is to investigate N2O production processes in situ field. We developed continuous N2O flux monitoring system, continuous measurement technique of N2O isotopomer ratio by laser spectroscopy, and soil microbial analysis method to investigate N2O production processes.
