Effect of Biological Denitrification Inhibitor on N₂O Emissions from Paddy Soil and Microbial Mechanisms [PDF]

Microorganisms
The denitrification process is the main process of the soil nitrogen (N) cycle in paddy fields, which leads to the production of large amounts of nitrous oxide (N2O) and increases N loss in paddy soil.
