“…Nitrogen fertilizer application has been recognized as the key factor for increasing NO and N 2 O emissions from agricultural field, because it provides substrates for driving soil nitrification and denitrification processes. Reducing total N input has been verified to be an effective measure for mitigating N 2 O emission from the agricultural field in the NCP (Ding et al, 2007;Ju et al, 2011;Shi et al, 2013;Yan et al, 2013). However, this strategy is not practical, because farmers usually prefer to use high fertilization rate for increasing crop yield.…”

“…However, this strategy is not practical, because farmers usually prefer to use high fertilization rate for increasing crop yield. Other optional measures for mitigating N 2 O emission were also investigated in the NCP, such as applying manure (Meng et al, 2005;Cai et al, 2013;Ding et al, 2013;Hu et al, 2013) and straw Hu et al, 2013), adding nitrification inhibitors and slow release fertilizer (Ding et al, 2010(Ding et al, , 2015Ju et al, 2011;Shi et al, 2013) and applying different kinds of nitrogen fertilizers (NH 4 + -N and NO 3 -N fertilizers) (Ju et al, 2011;Ding et al, 2015). Among these control measures, only the application of nitrification inhibitors and nitrate fertilizer are found to be effective (Ding et al, 2010(Ding et al, , 2015Ju et al, 2011).…”

“…Similar to other regions in northern China, Huantai County has experienced the agricultural intensification process including a high cropping intensity (200 %, winter wheat-summer maize), high fertilizer rate (500-600 kg N ha −1 yr −1 ), frequent irrigation and tillage, and an increasing ratio of crop residues incorporation since the 1980s (Shi et al, 2013;Kong et al, 2014). Agricultural intensification increased crop yield within a short period.…”

Abstract. Agricultural intensification has contributed greatly to the sustained food supply of China's population of 1.3 billion over the 30-year period from 1982 to 2011. Intensification has several and widely recognized negative environmental impacts including depletion of water resources, pollution of water bodies, greenhouse gas emissions and soil acidification. However, there have been few studies over this period on the impacts of intensification on soil organic carbon (SOC) at the regional level. The present study was conducted in Huantai County, a typical intensive farming region in northern China, to analyze the temporal dynamics of SOC influenced by climate and farming practices. The results indicate that from 1982 to 2011, SOC content and density in the 0-20 cm layer of the cropland increased from 7.8 ± 1.6 to 11.0 ± 2.3 g kg −1 (41 %) and from 21.4 ± 4.3 to 33.0 ± 7.0 Mg ha −1 (54 %), respectively. The SOC stock (0-20 cm) of the farmland for the entire county increased from 0.75 to 1.2 Tg (59 %). Correlation analysis revealed that incorporation of crop residues significantly increased SOC, while an increase in the mean annual temperature decreased the SOC level. Therefore, agricultural intensification has increased crop productivity and contributed to SOC sequestration in northern China. In the near future, more appropriate technologies and practices must be developed and implemented for a maintenance or enhancement of SOC in this region and elsewhere in northern China, which also reduce non-CO 2 greenhouse gas emissions, since the climate benefit from the additional SOC storage is estimated to be smaller than the negative climate impacts of N 2 O from N fertilizer additions.

“…As N-fertilizer is the necessary substrate for soil nitrification and denitrification, the huge amounts of N-fertilizer applications in this region can greatly stimulate N 2 O emission. Therefore, N 2 O emissions from the agricultural fields in the NCP have been investigated intensively (Zeng et al, 1995;Dong et al, 2000;Meng et al, 2005;Ding et al, 2007Ding et al, , 2013Sun et al, 2008;Wang et al, 2008Wang et al, , 2009Li et al, 2010;Cui et al, 2012;Cai et al, 2013;Hu et al, 2013;Shi et al, 2013;Yan et al, 2013). However, among those reports on N 2 O emissions from the fields, many studies were conducted for 1 year, and only the studies of Cai et al (2013), Hu et al (2013) and Yan et al (2013) implemented the N 2 O measurement for more than 1 year.…”

Abstract. Agricultural soil with fertilization is a main anthropogenic source for atmospheric nitrous oxide (N 2 O). N 2 O fluxes from a maize-wheat rotation field in the North China Plain (NCP) were investigated for 4 successive years using the static chamber method. The annual N 2 O fluxes from the control (without fertilization) and fertilization plots were 1.5 ± 0.2 and 9.4 ± 1.7 kg N ha in the corresponding years were 2.4 ± 0.5 %, 0.60 ± 0.01 %, 1.1 ± 0.09 % and 2.9 ± 0.2 %, respectively. Significant linear correlation between fertilized-induced N 2 O emissions (Y , kg N ha −1 ) during the periods of 10 days after fertilization and rainfall intensities from 4 days before to 10 days after fertilization (X, mm) in the 4 years was found as Y = 0.048X − 1.1 (N = 4, R 2 = 0.99, P < 0.05). Therefore, the remarkable interannual variations of N 2 O emissions and the EF d 's were mainly ascribed to the rainfall.
