Abstract
In order to explore the effects of nitrapyrin (N-Serve) application on greenhouse gas emission and nitrogen (N) leaching of a waterlogged maize (Zea mays L.) field, we investigated the effects of applying nitrapyrin on soil ammonium (NH4+-N) and nitrate nitrogen (NO3−-N) content, nitrous oxide (N2O) fluxes, and the warming potential (GWPN2O) in a waterlogged maize field. The design included three treatments: waterlogging treatment with only urea application (V-3WL), waterlogging treatment with urea and nitrapyrin application (V-3WL+N), and no waterlogging treatment applying only urea (CK). Our results revealed that waterlogging led to the increase of nitrate concentrations across the soil profile, thus potentially increasing N leaching and decreasing N use efficiency. The accumulated N2O emissions increased significantly in waterlogged plots compared to control plots, and maximum N2O emission fluxes occurred during the process of soil drying after waterlogging; this resulted in an increase in GWPN2O and N2O greenhouse gas intensity (GHGIN2O) by 299% and 504%, respectively, compared to those of CK. However, nitrapyrin application was able to reduce N2O emissions. Nitrapyrin application was also good for decreasing GWPN2O and GHGIN2O by 34% and 50%, respectively, compared to V-3WL. In addition, nitrapyrin application was conducive to reduce N leaching and improve N use efficiency, resulting in a yield increase by 34%, compared to that of V-3WL. The application of nitrapyrin helped to mitigate agriculture-source greenhouse effects and N leaching induced by waterlogging, and was a high N-efficient fertilizer method for a waterlogged field.
