Microbial and isotopomer analysis of $ N_{2} $O production pathways in a calcareous film-mulched farmland
Abstract The effects of long-term film mulching and primary nitrogen (N) fertilization strategies on the microbial processes underlying $ N_{2} $O emissions from calcareous upland soils are poorly understood. A two-year field experiment including five treatments viz. no mulching with recommended N (...

| 520 | |a Abstract The effects of long-term film mulching and primary nitrogen (N) fertilization strategies on the microbial processes underlying $ N_{2} $O emissions from calcareous upland soils are poorly understood. A two-year field experiment including five treatments viz. no mulching with recommended N ($ N_{225} $), film mulching with recommended N ($ F_{225} $), high dose N ($ F_{380} $), manure addition ($ F_{225+M} $), and no N ($ F_{0} $) was conducted to explore the $ N_{2} $O production pathways in a maize (Zea mays L.) cultivation system using combined isotopocule and quantitative PCR analysis. The cumulative $ N_{2} $O emissions were 0.56 − 0.68, 0.70 − 0.71, 1.06 − 1.07, 1.50 − 1.54, and 0.16 − 0.19 kg $ N_{2} $O-N $ ha^{−1} $ in $ N_{225} $, $ F_{225} $, $ F_{380} $, $ F_{225+M} $ and $ F_{0} $ treatments, respectively. Nitrifier denitrification and/or classical denitrification accounted for 53.4 − 85.0% of the total $ N_{2} $O emissions in the high $ N_{2} $O emission period. Long-term film mulching changed the $ N_{2} $O-related community composition and led to a significantly higher fraction of bacterial denitrification and/or nitrifier denitrification ($ f_{denitrification} $) in most events, compared with those in bare land. A relatively low $ f_{denitrification} $ and high $ N_{2} $O/($ N_{2} $O + $ N_{2} $) ratio often occurred in the $ F_{225+M} $ (in mixing-reduction scenario) and $ F_{380} $ treatments. Correlation analysis suggested that $ N_{2} $O fluxes were positively correlated with $ NO_{3} $−-N, dissolved organic N, total N, soil temperature, soil organic carbon, and the abundance of AOB amoA and nosZ genes, whereas they were negatively correlated with soil pH and C/N. Overall, our results suggest that long-term film mulching and N fertlization strategies could impact the processes of $ N_{2} $O production and consumption, whereas denitrification was still the primary $ N_{2} $O production pathways. | ||

Long-term film mulching changed the $ N_{2} $O-related community composition and led to a significantly higher fraction of bacterial denitrification and/or nitrifier denitrification ($ f_{denitrification} $) in most events, compared with those in bare land. A relatively low $ f_{denitrification} $ and high $ N_{2} $O/($ N_{2} $O + $ N_{2} $) ratio often occurred in the $ F_{225+M} $ (in mixing-reduction scenario) and $ F_{380} $ treatments. Correlation analysis suggested that $ N_{2} $O fluxes were positively correlated with $ NO_{3} $−-N, dissolved organic N, total N, soil temperature, soil organic carbon, and the abundance of AOB amoA and nosZ genes, whereas they were negatively correlated with soil pH and C/N. Overall, our results suggest that long-term film mulching and N fertlization strategies could impact the processes of $ N_{2} $O production and consumption, whereas denitrification was still the primary $ N_{2} $O production pathways.

Abstract The effects of long-term film mulching and primary nitrogen (N) fertilization strategies on the microbial processes underlying $ N_{2} $O emissions from calcareous upland soils are poorly understood. A two-year field experiment including five treatments viz. no mulching with recommended N ($ N_{225} $), film mulching with recommended N ($ F_{225} $), high dose N ($ F_{380} $), manure addition ($ F_{225+M} $), and no N ($ F_{0} $) was conducted to explore the $ N_{2} $O production pathways in a maize (Zea mays L.) cultivation system using combined isotopocule and quantitative PCR analysis. The cumulative $ N_{2} $O emissions were 0.56 − 0.68, 0.70 − 0.71, 1.06 − 1.07, 1.50 − 1.54, and 0.16 − 0.19 kg $ N_{2} $O-N $ ha^{−1} $ in $ N_{225} $, $ F_{225} $, $ F_{380} $, $ F_{225+M} $ and $ F_{0} $ treatments, respectively. Nitrifier denitrification and/or classical denitrification accounted for 53.4 − 85.0% of the total $ N_{2} $O emissions in the high $ N_{2} $O emission period. Long-term film mulching changed the $ N_{2} $O-related community composition and led to a significantly higher fraction of bacterial denitrification and/or nitrifier denitrification ($ f_{denitrification} $) in most events, compared with those in bare land.

Correlation analysis suggested that $ N_{2} $O fluxes were positively correlated with $ NO_{3} $−-N, dissolved organic N, total N, soil temperature, soil organic carbon, and the abundance of AOB amoA and nosZ genes, whereas they were negatively correlated with soil pH and C/N. Overall, our results suggest that long-term film mulching and N fertlization strategies could impact the processes of $ N_{2} $O production and consumption, whereas denitrification was still the primary $ N_{2} $O production pathways. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2023.

A two-year field experiment including five treatments viz. no mulching with recommended N ($ N_{225} $), film mulching with recommended N ($ F_{225} $), high dose N ($ F_{380} $), manure addition ($ F_{225+M} $), and no N ($ F_{0} $) was conducted to explore the $ N_{2} $O production pathways in a maize (Zea mays L.) cultivation system using combined isotopocule and quantitative PCR analysis. The cumulative $ N_{2} $O emissions were 0.56 − 0.68, 0.70 − 0.71, 1.06 − 1.07, 1.50 − 1.54, and 0.16 − 0.19 kg $ N_{2} $O-N $ ha^{−1} $ in $ N_{225} $, $ F_{225} $, $ F_{380} $, $ F_{225+M} $ and $ F_{0} $ treatments, respectively. Nitrifier denitrification and/or classical denitrification accounted for 53.4 − 85.0% of the total $ N_{2} $O emissions in the high $ N_{2} $O emission period. Long-term film mulching changed the $ N_{2} $O-related community composition and led to a significantly higher fraction of bacterial denitrification and/or nitrifier denitrification ($ f_{denitrification} $) in most events, compared with those in bare land. A relatively low $ f_{denitrification} $ and high $ N_{2} $O/($ N_{2} $O + $ N_{2} $) ratio often occurred in the $ F_{225+M} $ (in mixing-reduction scenario) and $ F_{380} $ treatments. Correlation analysis suggested that $ N_{2} $O fluxes were positively correlated with $ NO_{3} $−-N, dissolved organic N, total N, soil temperature, soil organic carbon, and the abundance of AOB amoA and nosZ genes, whereas they were negatively correlated with soil pH and C/N. Overall, our results suggest that long-term film mulching and N fertlization strategies could impact the processes of $ N_{2} $O production and consumption, whereas denitrification was still the primary $ N_{2} $O production pathways.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mulching</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">N</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O production pathway</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Gene abundance</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Isotopocule Manure</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Fangfang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bo, Qifei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tang, An</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gao, JiaRui</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wei, Xiongxiong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yue, Shanchao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shen, Yufang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Shiqing</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Biology and fertility of soils</subfield><subfield code="d">Springer Berlin Heidelberg, 1985</subfield><subfield code="g">59(2023), 4 vom: 18.
