“…Correlation analysis N 2 O emission was significantly and positively correlated with Tmax, Tmin, Tmean, WFPS, CO 2 and Mineral N (r= 0.5549, 0.5241, 0.7729, 0.8345, 0.8262, 0.8507, respectively, p<0.01; Table 3). Temperature, radiation and mineral N have been shown to increase soil microbial activity and decomposition of organic matter, which influences N 2 O emission (Oertel et al, 2012 ). The arid climate of Griffith and sandy loam texture of the soil contribute to high water loss though evaporation or infiltration.…”

“…Gas sampling was performed at 7–10‐day intervals at each subplot based on the GHG sampling protocol of GRACEnet Chamber‐based Trace Gas Flux Measurement (Parkin & Venterea, 2010; Tenesaca & Al‐Kaisi, 2015). In this sense, the well‐known static closed chamber method was used to measure CO 2 emissions (Oertel et al, 2012).…”

Emissions of CO2 from the soil are the second‐largest component of the global carbon cycle, which has altered the climate and led to climate change. The main aim of this research was to evaluate the direct impact of climate and soil management systems on soil carbon emissions. Thus, CO2 emissions were measured from maize fields located in two different climate regions (continental and semi‐arid). The experimental design involved two different soil management systems (conventional tillage [CT], non‐tillage [NT]) from two different sites (Debrecen [Hungary], Karaj [Iran]). The results showed that total CO2 emission from the cultivated system (CT) was higher than that from the non‐cultivated (NT) one, regardless of the climate region. However, CO2 emissions from agricultural soil in a humid region are significantly different (p < .05) from semi‐arid regions, which clearly emphasizes the role of climate conditions in the CO2 emission processes. However, the general linear model reveals that all studied variables (soil management systems, date of measurement, soil temperature, soil water content) had a significant (p < .05) effect on soil carbon emission, where the explained variance was 0.866. The findings of this research stress the importance of NT in CO2 mitigations on the farm scale. However, the output could help to draw up mitigation strategies to minimize the total greenhouse gas emissions from agricultural soil in both countries.

“…The N 2 O emissions were measured using the sampling protocol of GRACEnet Chamber-based Trace Gas Flux Measurement (Parkin & Venterea, 2010). The samples were collected in both fields (CT and NT) for 7 to 10 days intervals and every 2 weeks (during wintertime) using the static closed chamber method (Oertel et al, 2012). The chamber was 12.5 cm high and had a diameter of 15 cm constructed on polyvinyl chloride (PVC).…”

Agricultural activity is the major anthropogenic source of nitrous oxide (N2O) emissions from terrestrial ecosystems. Conservation agriculture including crop residue management can play a key role in enhancing soil resilience to climate change and mitigating N2O emissions. We investigated the effects of crop residue rates, including 100 % (R100), 50 % (R50), and residue removal (R0), on N2O emissions in corn-wheat rotation under conventional (CT) and no-tillage (NT) systems. The key factors evaluated affecting N2O emissions included soil temperature, soil moisture, soil ammonium, and soil nitrate concentrations. Results showed that the N2O emissions increased with the increasing rate of residue under both CT and NT systems. Both R100 and R50 significantly ( p < .05) increased the N2O emissions compared to R0 during the annual rotation cycle. Soil moisture and mineral nitrogen (ammonium and nitrate) were the main driving factors that stimulated N2O emission in both CT and NT systems. In the NT and CT systems, cumulative N2O emissions showed a significant increase with R50 (+75.5 % in NT, +36.5 % in CT) and R100 (+134 % in NT, +40 % in CT) as compared to R0. Furthermore, no significant differences were found between R100 and R50 in the CT system, while in the NT system significant increases were observed for R100 compared to R50. Overall, our study justified as a first approach only during the first year that crop residue removal led to decreased N2O emissions under semi-arid conditions. However, due to the deteriorating impact of crop residue removal on crop productivity and soil C sequestration, this management method cannot be considered a sustainable agronomic practice. We suggest long-term studies to determine the appropriate rate of postharvest crop residue to achieve less N2O emissions and climate-friendly agricultural practices.
