| description | Ammonia (NH3) volatilization from nitrogen fertilizers is a major contributor to atmospheric particulate matter, posing risks to environmental and agricultural sustainability. This study evaluated NH3 emissions during Chinese cabbage cultivation under three fertilization regimes: urea (UR), solid manure compost (SMC), and a combined application of both (UR+SMC). Field-based static chamber measurements were conducted, and the influence of environmental and soil variables on NH3 volatilization was assessed using random forest modeling. Results showed that UR treatments led to significantly higher NH3 emissions than SMC, primarily due to rapid urea hydrolysis under moist and warm conditions. In contrast, SMC exhibited a brief emission peak immediately after application, followed by minimal release, indicating the slower mineralization of organic nitrogen. The UR+SMC treatment resulted in the highest cumulative NH3 loss, highlighting potential risks associated with combined fertilization. However, despite this high emission level, the crop yield in the UR+SMC treatment was lower than that observed with UR alone, suggesting that combined fertilization may not provide agronomic benefits proportional to its environmental cost. Soil analysis revealed that nitrogen inputs altered pH, organic matter content, and available nutrients, while temperature and soil moisture were identified as the dominant environmental drivers of NH3 emissions. These findings provide critical insights for optimizing fertilizer management strategies to reduce nitrogen losses while maintaining crop productivity. |
