Abstract: Nitrogen emissions from agricultural activities have garnered increasing attention due to their implications for environmental sustainability. Field studies conducted throughout a month is needed to improve flux estimates for the greenhouse gas nitrous oxide (N2O). In this study, we reported N2O emissions measured using gas chromatograph equipped with an electron capture detector. The soil at the experimental site was loamy. N2O emissions were significantly higher from the root systems of nodulating soybeans compared to non-nodulating soybeans during the late growth period. To mitigate nitrogen emissions in soybean cultivation, optimize fertilizer application, promote biological nitrogen fixation through inoculation and legume cover cropping, implement crop rotation, use cover crops, reduce nitrogen loss through erosion control, manage irrigation efficiently, employ precision agriculture, educate on nutrient stewardship, utilize biofertilizers, conduct environmental monitoring, invest in legume breeding, and enact government regulations and incentives for sustainable nitrogen management practices. Therefore, this study significantly advances our knowledge of sustainable soybean cultivation and the pivotal role and means in mitigating environmental challenges linked to nitrogen emissions.
