“…Seasonlong N 2 O emissions averaged 4.7 kg N 2 O ha −1 season −1 across all treatment combinations. The range of season-long N 2 O emissions reported in the current study was more than three times greater than the range of season-long emissions reported by Rector et al (2018) from a delayed-flood rice production system (1.0-1.5 kg N 2 O ha −1 season −1 ) in the field under conventional tillage on a silt-loam soil in east-central Arkansas, but was substantially lower than season-long emissions reported from the upper portion of a production-scale, furrow-irrigated rice field (4.5-24.5 kg N 2 O ha −1 season −1 ) in east-central Arkansas (Della Lunga, Brye, Slayden, et al, 2023;Slayden et al, 2021). Measured season-long N 2 O emissions suggested that the two water regimes used in the current greenhouse study more closely matched processes observed and emissions measured from flooded than in furrow-irrigated conditions, particularly from the perspective of nitrification-denitrification coupled reactions.…”

“…The Mg provided by ECST also could have played a role in decreasing CH 4 production and emissions (Figure 5). A negative correlation between soil Mg concentration and season-long CH 4 emissions has been reported in previous studies from rice fields under flooded and furrow-irrigated conditions (Della Lunga et al, 2021;Della Lunga, Brye, Slayden, 2023;Huang et al, 2002), although the actual causeeffect relationship remains unclear. The pelletized form of CPST and the powdered form of ECST also likely contributed to measured differences in CH 4 emissions from the struvite-P sources (Figure 5).…”

“…Being a relatively new management practice in rice production systems, furrow-irrigation and subsequent production and release of GHGs have not been evaluated in large-scale, long-term studies worldwide yet. Although a few studies have evaluated season-long emissions in rice under furrow-irrigated conditions in Arkansas (Della Lunga, Brye, Slayden, et al, 2023;Karki et al, 2022), several studies have highlighted the substantial impact of different water regimes, specifically AWD, in rice fields (Z.

“…The current study encompassed one growing season from May to September 2021. Following procedures described by Della Lunga, Brye, Slayden, et al (2023) and J. Brye (2024), fifteen 51-L plastic tubs (67 cm long, 15 cm tall, 51 cm wide) were prepared and placed in a greenhouse at the Milo J. Shult Agricultural Research and Extension Center (SAREC) in Fayetteville, AR, with a split-plot design, where the wholeplot factor was arranged as a complete randomized block design with three blocks (i.e., replications).…”

“…Similar to the methods adopted in previous studies (Della Lunga, Brye, Roberts, et al, 2020Della Lunga, Brye, Slayden, et al, 2023;Rector et al, 2018;Rogers et al, 2014;Slayden et al, 2022;Smartt et al, 2016), gas fluxes were calculated using the best fit of a linear regression among the concentrations measured for the three time points (i.e., 0, 30, and 60 min). Only gas fluxes with linear regression slopes ≥0 were retained for the final dataset; thus, only GHG emissions, and not uptakes, were evaluated in this study.…”

Greenhouse gas (GHG) emissions from rice (Oryza sativa) systems have been correlated to water management practice, but to date, no study has directly evaluated three main GHGs (i.e., methane [CH4], nitrous oxide [N2O], and carbon dioxide [CO2]) under flood‐ and furrow‐irrigated conditions at the same time as affected by various fertilizer‐phosphorus (P) sources, in particular the reportedly slow‐release struvite‐P source. Therefore, the objective of this study was to evaluate the effect of water regime (flooded and furrow‐irrigated) and fertilizer‐P source (diammonium phosphate, chemically precipitated struvite, electrochemically precipitated struvite [ECST], triple superphosphate, and an unamended control) on GHG emissions and two‐ and three‐gas global warming potentials (GWP* and GWP, respectively) in the greenhouse. Methane emissions were 10 times greater (p < 0.05) under flooded (29.4 kg CH4 ha−1 season−1) than under furrow‐irrigated conditions (2.9 kg CH4 ha−1 season−1), and four times lower (p < 0.05) with ECST (3.4 kg CH4 ha−1 season−1) than other fertilizer‐P sources, while CO2 emissions were three times greater (p < 0.05) under furrow‐irrigated (23,428 kg CO2 ha−1 season−1) than under flooded (8290 kg CO2 ha−1 season−1) conditions. The GWP* under furrow‐irrigated conditions was almost 40% lower (p < 0.05) than under flooded conditions. Although N2O emissions were unaffected by fertilizer‐P source, the N2O contribution to GWP* was more than 80% under furrow‐irrigated conditions. Flood‐ and furrow‐irrigated water regimes require diversified approaches in GHG mitigation, where the best management for ECST needs to be more fully evaluated.

Phosphorus (P) fertilizers with low water solubility, like struvite (MgNH4PO4·6H2O), have been identified to possibly reduce nutrient losses in furrow-irrigated cropping systems. However, there is a lack of research on the impacts of P and nitrogen (N) fertilization on greenhouse gas [GHG; i.e., methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2)] production in furrow-irrigated rice (Oryza sativa). The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (CPST), triple superphosphate (TSP), diammonium phosphate (DAP), environmentally smart nitrogen (ESN), and an unamended control (CT) on GHG emissions, global warming potential (GWP), and plant and soil responses at the up-slope position of a furrow-irrigated rice field in east-central Arkansas. Seasonal CH4 and CO2 emissions did not differ (P > 0.05) among fertilizer treatments, while N2O emissions were greater (P = 0.02) from CT (i.e., 5.97 kg ha−1 season−1), which did not differ from ECST, and were lowest from ESN (1.50 kg ha−1 season−1), which did not differ from TSP, CPST, ECST, and DAP. Global warming potential was greatest (P < 0.05) from CT (1612 kg CO2 eq. ha−1 season−1), which did not differ from ECST, and was lowest from ESN (436 kg CO2 eq. ha−1 season−1), which did not differ from TSP, ECST, CPST, and DAP. The combination of numerically greater yield and lower N2O emissions from CPST and ESN suggested that slow-release fertilizers could constitute an effective mitigation tool to reduce GHG emissions, maintain production, and improve sustainability in furrow-irrigated rice systems.

The cultivation of rice is one of the main sources of greenhouse gas (GHG) emissions due to continuously flooded irrigation (CF), which demands large volumes of water. As an alternative solution, alternate wetting and drying (AWD) irrigation has been developed as a water-saving strategy. This study was conducted at the Experimental Agricultural Station (EEA) in Vista, Florida, in the Lambayeque region located on the northern coast of Peru. Thus, it was analyzed the effect of AWD irrigation at different depths (5, 10, and less than 20 cm below the surface) compared to CF control on methane (CH4) and nitrous oxide (N2O) emissions and rice grain yield. AWD treatments reduced CH4 emissions by 84% to 99% but increased N2O emissions by 66% to 273%. In terms of Global Warming Potential (GWP), the AWD10 treatment demonstrated a 77% reduction and a Water Use Efficiency (WUE) of 0.96, affecting only a 2% decrease in rice grain yield, which ranged between 11.85 and 14.01 t ha−1. Likewise, this study provides sufficient evidence for the adoption of AWD irrigation as a strategy for the efficient use of water resources and the mitigation of GHG emissions in rice cultivation in the study area, compared to continuous flooded irrigation.
