Co-application of a biochar and an electric potential accelerates soil nitrate removal while decreasing N₂O emission
Denitrification is an important mechanism for mitigating groundwater nitrate (NO3−) pollution. Our previous results showed that electric potential application (−0.5 V versus standard hydrogen electrode) accelerated subsoil ...
Enhancement of subsoil denitrification using an electrode as an electron donor
Laboratory culture studies have demonstrated that some microbial strains can use electrons generated by electrodes in the denitrification reaction. To test whether the native soil microbiota can use electrode electrons for ...
Rice root Fe plaque enhances paddy soil N₂O emissions via Fe(II) oxidation-coupled denitrification
Iron (Fe) plaque, defined as a film of poorly crystalline Fe oxides deposited on the surface of rice roots, potentially mediates paddy-soil N₂O emissions. The aims of this study were to test if, and how, Fe plaque affects ...
Identification and verification of key functional groups of biochar influencing soil N₂O emission
(Springer Nature, 2021-01-26)
Biochars containing abundant and diverse functional groups can influence soil nitrous oxide (N₂O) emissions. It remains unclear how these functional groups alter soil N₂O emissions and which specific functional groups are ...
N₂ production via aerobic pathways may play a significant role in nitrogen cycling in upland soils
The importance of di-nitrogen (N₂) production via aerobic pathways has been verified in a significant number of pure microbial strains. However, to date there are no reports confirming this in situ. In this study, we ...
