“…However, the experimental conditions could be considered as comparable between cropping systems, thereby allowing us to compare their emissions; thus, seasonal patterns were identified for the different systems. The emission levels of systems S1, S3, and S5 were globally comparable to those observed in 2011 in the same area (Vermue et al 2013), as well as to punctual measurements performed in the agricultural region of eastern France (Henault et al 1998) for comparable pedoclimatic conditions.…”

Integrated weed management aims to decrease the dependence of cropping systems on herbicides by using a combination of several agricultural practices. Environmental impacts of individual practices under various conditions are already known. However, there is scarce knowledge on the impact of combining several practices. Therefore, we studied N 2 O emissions of weed management cropping systems that use differing practices such as crop diversity, tillage, and herbicide pressure, during about 1 year. Data were compared with a conventionally managed cropping system. Results were also simulated using the NOE model. Results show a large variation of N 2 O emissions, ranging from 177 g N 2 O-N/ha for intensive tillage integrated weed management to 362 g N 2 O-N/ha for the conventional cropping system, 777 g N2O-N/ha for the no herbicide cropping system and 5226 g N 2 O-N/ha for no-till integrated weed management. Most N 2 O emissions occurred in spring, despite the absence of fertilizing related N 2 O peaks. The lowest emissions occurred in autumn and winter. Emissions are explained by interactions between specific soil potential denitrification rate, soil bulk density, temperature, soil water, and inorganic N contents. N 2 O emissions are accurately predicted by the model NOE, with a global Nash-Sutcliffe coefficient of efficiency equal to 0.80.

“…Dobbie et al (1999) obtained higher emission factors from potato and brassica crops (1.8-7% of N applied) than for wheat and barley (0.2-0.7% of N applied). This was also found by Henault et al (1998) for wheat compared to oil seed rape (0.42 compared to 0.55%). Similar observations have been made by Brumme et al (1999) regarding the litter quality in forested ecosystems.…”

The results of a literature study examining quantitative estimates of N 2 O emission rates are presented for a range of land-uses across Europe. The analysis shows that the highest N 2 O emission rates are for agricultural lands compared to forests and grasslands. The main factors regulating these rates are available mineral nitrogen, soil temperature, soil water content and the available labile organic compounds. These controls operate across different time-scales, all must exceed a certain threshold for N 2 O emission to occur. The results support the need for an emission factor function of land-use and climate within models describing nitrogen dynamics in catchments. This would allow the assessment of the net N 2 O emission within catchments in terms of current levels and potential changes associated with climate variability, climate change and land use change.

“…Because the cumulative N 2 O emissions usually Ding et al (2013) linearly correlate with fertilization rates (Henault et al, 1998;De Klein et al, 2006;Halvorson et al, 2008), the above experiential algorithm for estimating the annual cumulative N 2 O emissions from agricultural fields could be expressed in a more general form:…”

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.
