IntroductionBrachiaria humidicola, a tropical grass, could release root exudates with biological nitrification inhibition (BNI) capacity and reduce soil nitrous oxide (N2O) emissions from grasslands. However, evidence of the reduction effect in situ in tropical grasslands in China is lacking.MethodsTo evaluate the potential effects of B. humidicola on soil N2O emissions, a 2-year (2015–2017) field experiment was established in a Latosol and included eight treatments, consisting of two pastures, non-native B. humidicola and a native grass, Eremochloa ophiuroide, with four nitrogen (N) application rates. The annual urea application rates were 0, 150, 300, and 450 kg N ha−1.ResultsThe average 2-year E. ophiuroides biomass with and without N fertilization were 9.07–11.45 and 7.34 t ha−1, respectively, and corresponding values for B. humidicola increased to 31.97–39.07 and 29.54 t ha−1, respectively. The N-use efficiencies under E. ophiuroide and B. humidicola cultivation were 9.3–12.0 and 35.5–39.4%, respectively. Annual N2O emissions in the E. ophiuroides and B. humidicola fields were 1.37 and 2.83 kg N2O-N ha−1, respectively, under no N fertilization, and 1.54–3.46 and 4.30–7.19 kg N2O-N ha−1, respectively, under N fertilization.DiscussionsAccording to the results, B. humidicola cultivation increased soil N2O emissions, especially under N fertilization. This is because B. humidicola exhibited the more effective stimulation effect on N2O production via denitrification primarily due to increased soil organic carbon and exudates than the inhibition effect on N2O production via autotrophic nitrification. Annual yield-scaled N2O emissions in the B. humidicola treatment were 93.02–183.12 mg N2O-N kg−1 biomass, which were significantly lower than those in the E. ophiuroides treatment. Overall, our results suggest that cultivation of the non-native grass, B. humidicola with BNI capacity, increased soil N2O emissions, while decreasing yield-scaled N2O emissions, when compared with native grass cultivation.

“…A gas sampling connection was incorporated into one side of the drum, consisting of a silicone hose attached to a three-way valve connected to a 60 mL syringe for gas sample extraction. Additionally, a thermometer was installed at the top to measure the chamber's internal temperature [23]. To ensure homogeneous gas distribution during sample collection, a fan powered by a portable battery was installed inside [7,[24][25][26].…”

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.
