“…The water droplet heat and mass transfer at humid atmospheric air is taken into account when assessing atmospheric appearance and creating climate models [1]. Water spray application in air conditioning [2], fire suppression [3][4][5][6][7], gas cooling [8,9] and agricultural irrigation systems [10,11] can be considered as traditional.

“…The irrigation was triggered when SMP at a depth of 0.2 m directly under the sprinklers reached −24.5 kPa, and the irrigation was stopped when the amount of water applied in each irrigation event was about 10 mm. The topsoil in sprinkler-irrigated fields was looser than that in flood-irrigated fields [36]. The [37].…”

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.

“…Sprinkling irrigation compared with furrow irrigation increases soil porosity, improves soil permeability. The topsoil in sprinkling irrigation fields was looser than that in furrow irrigation fields (Sun et al, 2008). Sprinkling irrigation is one of the water-saving irrigation methods widely adopted in agricultural production.…”

Sprinkling water is applied in shorter irrigation intervals and lighter irrigation applications in arid areas. The water-saving irrigation is the primary method of local agricultural production. Since chemical fertilizer is the primary emission source of nitrous oxide (N2O), it is appropriate to verify the general influence of water-saving irrigation on N2O. Results of the study, conducted in a potato field as the experimental site for two consecutive years, using two different irrigation systemsnamely, furrow (FI) and sprinkling-irrigation (SI) with a mineral N fertilizer (NF) and a control without any fertilizer (Control) are reported. The N2O emission fluxes with NF were higher than those of the control in each irrigation system. On plots where the NF was applied, mean emissions fluxes of N2O was 152.02 μg/(m 2 hr) in FI, 36.53μg/(m 2 hr) in SI from 2016 to 2017. The reduction of N2O emissions from SI was due to the lower amount of water applied every time and the lower NO3 --N and NH4 + -N of soil associated with SI. This work showed that SI is a method that helps save water and mitigates emissions of the atmospheric N2O pollutants compared to FI.
