Based on an ongoing long-term field experiment commenced in 2011 on the Chinese Loess Plateau, we investigated the responses of soil properties, wheat yield and yield stability of winter wheat (Triticum aestivum L.) to ammoniated and conventional straw incorporation during 2017–2020. The three treatments were: (i) no straw (Control), (ii) conventional straw incorporation (CSI), and (iii) ammoniated straw incorporation (ASI). We found that the ASI treatment on average significantly increased wheat yield by 10.1% and yield stability by 19.5% compared to the CSI treatment, and significantly increased wheat yield by 26.9% and yield stability by 38.7% compared to the Control treatment. Changes in wheat yield and yield stability were positively related to ASI-induced increases in soil water storage. When compared to the Control and CSI treatments, the ASI treatment on average significantly increased soil organic carbon (SOC) content by 17.2% and 14.2% and total nitrogen (TN) content by 27.3% and 18.3% in 0–10 cm depth, and it significantly increased SOC content by 19.2% and 12.4% and TN content by 27.8% and 19.4% in 10–20 cm depth, respectively. There were positive relationships between changes in wheat yield and SOC and TN content. These results demonstrate that it is feasible to achieve higher wheat yield and yield stability while increasing SOC and TN content by optimizing straw management practices in semi-arid areas.",
