“…Soil moisture is one of the great significance indicators of soil properties during rice-growing seasons and has impacts on greenhouse gas emissions by changing soil permeability, microbial activity and Eh (soil redox potential) [45]. Water content did not change significantly in continuous flooding conditions; the water layer had a constant height of 3-5 cm.…”

Irrigation regime and fertilizer nitrogen (N) are considered as the most effective agricultural management systems to mitigate greenhouse gas (GHG) emissions from crop fields, but few studies have involved saline-alkaline paddy soil. Gas emitted from saline-alkaline paddy fields (1-year-old and 57-year-old) was collected during rice growing seasons by the closed chamber method. Compared to continuous flooding irrigation, lower average CH 4 flux (by 22.81% and 23.62%), but higher CO 2 flux (by 24.84% and 32.39%) was observed from intermittent irrigation fields. No significant differences of N 2 O flux were detected. Application rates of N fertilizer were as follows: (1) No N (N0); (2) 60 kg ha −1 (N60); (3) 150 kg ha −1 (N150); and (4) 250 kg ha −1 (N250). The cumulative emissions of GHG and N fertilizer additions have positive correlation, and the largest emission was detected at the rate of 250 kg N ha −1 (N250). Global warming potential (GWP, CH 4 + N 2 O + CO 2 ) of the 57-year-old field under the N250 treatment was up to 4549 ± 296 g CO 2 -eq m −2 , approximately 1.5-fold that of N0 (no N application). In summary, the results suggest that intermittent irrigation would be a better regime to weaken the combined GWP of CH 4 and N 2 O, but N fertilizer contributed positively to the GWP.

Irrigation and soil management can impact soil nitrous oxide (N2O) emissions. Flood and sprinkler irrigation systems together with conventional tillage are the main practices used in the high yielding maize systems in Mediterranean Spain. The objective of this field work was to quantify the effect of the irrigation system (i.e., flood, F; and sprinkler, S) and the soil tillage system (i.e., conventional tillage, CT; no‐tillage maintaining the maize stover, NTr; and no‐tillage removing the maize stover, NT) on the N2O emissions from the soil during 3 yr (2015, 2016, and 2017). S irrigation, with mean values of 1.35 kg N2O‐N ha−1 yr−1 throughout the 3 yr, obtained 42% lower N2O emissions than F irrigation. On average of the three growing seasons, yield‐scaled N2O emissions by grain yield and by grain N uptake in F irrigation were two‐fold higher than in S irrigation. Moreover, in one out of three growing seasons (2017), no‐tillage systems (i.e., NTr and NT) showed greater yield‐scaled N2O emissions compared with CT. The higher maize grain yield with the S irrigation compared to F irrigation, as well as the lower N2O emissions reported under S irrigation resulted in the reduction of the yield‐scaled N2O emissions. Our findings highlight the role of sprinkler irrigation decreasing N2O emissions in comparison to flood irrigation in Mediterranean agroecosystems.

“…The changes in the differences in nitrogen cycles affect the temporal and spatial distribution for various forms of nitrogen in the soil and the formation of N 2 O. The different soil conditions of different irrigated crops greatly affect soil microbial processes of nitrification and denitrification, which control N 2 O production in soils [6,7]. In arid and semi-arid regions, FI is the most popular traditional surface irrigation system in China [5].…”

In arid and semi-arid regions, water-saving irrigation is the primary mode of local agricultural production. Since the chemical fertilizer is the principal source of nitrous oxide (N 2 O) emissions, we present results from a two-year (2016-2017) field experiment on a potato field to verify the general influence of water-saving irrigation on N 2 O emissions. A split-plot experiment was established with two irrigation systems and two fertilizer treatments, which give a total of four treatments. Two different irrigation systems were investigated: (i) flood irrigation with nitrogen fertilizer (NF-FI) combined with a control without any fertilizer (C-FI) and (ii) overhead sprinkler irrigation with a nitrogen fertilizer (NF-SI) accompanied with a control without any fertilizer (C-SI). The N 2 O emissions of the fertilizer treatment were greater than those of the control under each irrigation system. In plots where the fertilizers were applied, using overhead sprinkler irrigation reduced the average cumulative N 2 O emissions between 40.72% and 59.65% compared with flood irrigation. This was mainly due to the lower amount of water applied and the lower availability of NO 3 − -N and NH 4 + -N of soil associated with an overhead sprinkler irrigation. This work shows that the overhead sprinkler irrigation is an effective strategy to use to save water and mitigate emissions of the atmospheric pollutants N 2 O in comparison to flood irrigation.
