nirS and nosZII bacterial denitrifiers as well as fungal denitrifiers are coupled with N2O emissions in long-term fertilized soils

observed after inorganic fertilizer application. The results demonstrated that organic fertilization had a significant impact on the community structure and activity of soil denitrifying bacteria and fungi. Our results also highlighted that after organic fertilizer application, nirS-and nosZII-denitrifying bacteria communities represent likely hot spots of bacterial soil N2O emissions while nirK-type denitrifying fungi represent hot spots for fungal soil N2O emissions.

Automated summary

Organic fertilizer has a significant impact on the community structure and activity of soil denitrifying bacteria and fungi. Results suggest that nirS and nosZII denitrifying bacteria may act as hot spots for bacterial N2O emissions, while nirK denitrifying fungi may act as hot spots for fungal N2O emissions.
