We combine field observations, microcosm, stoichiometry and molecular stable isotope techniques to quantify N2O generation processes in an intensively managed low carbon calcareous fluvo-aquic soil. All the evidence points ammonia oxidation linked nitrifier denitrification (ND) being major generating N2O. When NH4+-based fertilizers are applied soil will produce high peaks which inhibited almost completely by adding nitrification inhibitors. During with NH4+ concentrations (>80 mg N kg−1)...
Abstract. The effects of nitrogen and straw management on global warming potential (GWP) greenhouse gas intensity (GHGI) in a winter wheat–summer maize double-cropping system the North China Plain were investigated. We measured nitrous oxide (N2O) emissions studied net GWP (NGWP) GHGI by calculating exchange CO2 equivalent (CO2-eq) from emissions, agricultural inputs practices, as well changes soil organic carbon (SOC), based long-term field experiment established 2006. includes six...
The IPCC assume a linear relationship between nitrogen (N) application rate and nitrous oxide (N2O) emissions in inventory reporting, however, growing number of studies show nonlinear under specific soil-climatic conditions. In the North China plain, global hotspot N2O emissions, covering land as large Germany, correlation N remains unclear. We have therefore specifically investigated response to applications by conducting field experiments with five rates, high-frequency measurements across...
Abstract Soil carbon sequestration is being considered as a potential pathway to mitigate climate change. Cropland soils could provide sink for that can be modified by farming practices; however, they also act source of greenhouse gases ( GHG ), including not only nitrous oxide (N 2 O) and methane CH 4 but the upstream dioxide CO ) emissions associated with agronomic management. These latter are sometimes termed “hidden” or “embedded” . In this paper, we estimated net balance Chinese...
Abstract. Nitrous oxide (N2O) is a long-lived greenhouse gas with large radiation intensity and it emitted mainly from agricultural land. Accurate estimates of total direct N2O emissions croplands on country scale are important for global budgets anthropogenic sources the development effective mitigation strategies. The objectives this study were to re-estimate using localized emission factors database measurements Chinese croplands. We obtained paddy fields (0.41 ± 0.04%) uplands (1.05...
Summary Koji making is an essential step in the production of high‐quality soy sauce. In this study, we inoculated koji with a halophilic aromatic yeast ( Zygosaccharomyces rouxii ) and Aspergillus oryzae investigated effects on volatile compounds quality sauce moromi. Our results suggest that optimal inoculation was approximately 1.5 × 10 6 per gram koji, excessive greatly decreased A. enzyme activity. comparison control group, there were no significant changes concentrations amino...
We investigated the linkages between composition and abundance of ammonia –oxidizing bacteria (AOB) denitrifiers emissions N 2 O in a summer maize ( Zea mays L.) field calcareous, intensively managed, agricultural soil. The treatments were zero‐N (control), NH 4 + –based fertilizer (favoring nitrification), NO 3 − glucose soil compaction (NO +Glu+Com, favoring denitrification), urea straw (U+S, representing conventional farming practices). observed substantial period (approximately 1 wk)...
Core Ideas Effects of improved N management on net GWP and GHG intensity were investigated. Fertilizer production irrigation the main contributors to GWP. Optimized chemical manure can decrease relative conventional N. Improved could realize food security mitigation concomitantly. Agricultural is one sources greenhouse gas (GHG) emissions globally. Net global warming potential (net GWP) (GHGI) investigated in a maize–wheat rotation from 2011 2014 North China Plain by summarizing exchange CO...
Nitrogen oxides (NO x ) have long been the focus of air pollution control. Examining spatial and driving characteristics NO emissions at urban scale from supply-chain perspective is critical. Using inventory method environmentally extended input–output analysis, energy-related 90 cities in eastern China were calculated, patterns sectors analyzed both production- consumption-based perspectives. The results show that production-based Chinese are substantially affected by their industrial...

We monitored soil respiration (Rs), temperature (T) and volumetric water content (VWC%) over four years in one typical conventional alternative cropping systems to understand Rs different with their respective management practices environmental conditions. The control was double-cropping system (winter wheat summer maize year - Con.W/M). Four were designed optimum N management, i.e. optimized winter (Opt.W/M), three harvests every two (first year, or soybean; second fallow then spring W/M-M...
